The Inheritance Ceremony Arc ((継承式編, Keishō-Shiki-hen?)) is the 5th story arc of the Katekyo Hitman Reborn! series. It was initially about Tsuna officially inheriting the title of Vongola Decimo from Vongola Nono, but turned into a war between the Vongola Decimo and his Guardians and the Simon Decimo and his Guardians.
The Simon Famiglia ArrivesThe Inheritance Ceremony Arc begins one month after the end of the Future Final Battle Arc. Reborn receives a message from the Vongola Nono and informs Tsuna that in a week, the Inheritance Ceremony would take place, establishing Tsuna as Vongola Decimo. At the same time seven new transfer students from Simon Middle School arrive due to earthquake warnings in their area. In no time Adelheid Suzuki is attempting to take over Hibari's Discplinary committee and Gokudera begins stalking Shitt P! (who he believed was a U.M.A). On his way back from school Tsuna and one of the transfer students Enma Kozato are beaten up by bullies. At this time Tsuna felt his Vongola Ring resonate with something prompting Reborn to investigate the Simon. Meanwhile, Ryohei gets into a fight with Kouyou Aoba during detention, Yamamoto becomes friendly with Kaoru Mizuno during baseball practice, and Julie Kato begins stalking Chrome Dokuro. Finding Enma, on the way home Tsuna noticed how similar he was to old self before he met Reborn. The next day at school, Adelheid and Hibari fight on the roof so Tsuna, along with his guardians and the other Simon students gather to stop the fight. Reborn then reveals that the Simon were in fact another Mafia Famiglia, known as friends of Vongola Primo and been invited as guests to Tsuna's Inheritance Ceremony. After school Tsuna discusses his misgivings over becoming the Vongola Boss with Enma who recommends he run away. At this point however a hitman from the Pesca Famiglia arrives in an attempt to kill Tsuna and to interfere with the upcoming Inheritance Ceremony but Tsuna defeats him easily. After finding this out Gokudera calls for a gathering between the Simon Famiglia and the Vongola Famiglia and splits everyone into groups to protect Tsuna. During the next few days Reborn observes the Simon Famiglia noting Kouyou and Ryohei finally working together, Kaoru regaining his confidence thanks to Yamamoto and Shitt P! communicating with Gokudera. Julie also asks Chrome on a date but is rejected. At around the same time, the Giegue Famiglia finds the location of the group that is trying to interfere with the Inheritance Ceremony at an abandoned factory. Although they try to take them out for the Vongola, they are killed by a mysterious female fighter who possesses a new flame type. Meanwhile, unsure of Tsuna's true motives Enma decides to test him, writing a note for Tsuna asking for his help, but unfortunately it is blown into the bin by accident and Enma is left waiting alone.
Tsuna goes for a meeting with the Ninth (who had arrived in Japan with his Guardian's) who tells him that Tsuna has the potential to destroy the corruption of the Vongola and return it to the ways of the first Famiglia, a vigilante group. Despite this, Tsuna refuses to become the new boss as he doesn't want to involve his friends. Later, Yamamoto is brutally attacked by Kaoru after seeing a slip of paper with the Vongola crest crossed out. He is found by Ryohei and taken to the hospital but is left in a coma. The only clue is the word Sin which Yamamoto wrote in blood which Reborn states would be given to Tsuna during the Ceremony suggesting the assailant will attack then. Filled with anger, Tsuna decides to go ahead with the ceremony in order to lure them out.
The Tenth's Guardians arrive at the ceremony and reunite with Naito Longchamp, Dino, and the Varia – except for Xanxus. The Simon Famiglia is also present, and they are surprised at seeing Yamamoto there and well.During the passing of the Vongola Sin, the Simon intervene and cause the Ninth to drop the Sin. He reassures Tsuna that it was merely a fake, and that the real Sin was inside a foolproof safe in another room. Just then, Enma reveals that he has broken into the safe and taken the Sin. He drips it onto his hand, which then transforms into a gauntlet. He reveals the story between Giotto and Simon Cozzato, and declares that he will bring the Simon Famiglia back to its former glory for that. The other six members then get the Sin onto their hands, and reveal their hidden power, said to rival the Vongola's Seven Sky Flames – the Seven Earth Flames.
Afterwards, Tsuna enters Hyper Dying Will Mode, but before he gets a chance to do anything, Enma uses his powers to crush Hibari, Gokudera, Chrome and Ryohei with ease, also revealing Yamamoto to be an illusion. Enma then proceeds to announce he only hasn't attacked Tsuna to make him experience the pain of Simon, and breaks the Vongola Rings of Sun, Cloud, Mist and Storm. Tsuna then attacks Enma, causing a reaction on their respective Rings, but he is overpowered. Adelheid then announces that Enma's powers will take seven days to reach full power, and thus Enma is only using a seventh of it, to the shock of both Reborn and Tsuna. After overwhelming Dino and the Varia, and finally breaking the Vongola Ring of Sky, the Simon take their leave with Julie taking Chrome saying they have date plans.
When Tsuna and his Guardians feel helpless, a mysterious old man who seems to be an acquaintance of the Ninth arrives. He also seems to have known Primo. His name is revealed to be Talbot. Talbot asks Tsuna if he is ready to bring the rings back, even with the risk of destroying the rings. Tsuna agrees to this, and Talbot talks to Ninth, requesting a room to himself. He upgrades the broken rings with the Box Weapons and Vongola Primo's blood, Penalty. Upon upgrading the Vongola rings, they look like nothing more than rocks. Talbot then says that the rocks have to be injected with an extreme amount of Dying Will. Tsuna, Gokudera, Ryohei and Hibari successfully unlock the powers of their respective rings, bringing forth the Sky Ring, the Storm Buckle, the Sun Bangle and the Cloud Bracelet.
Following this, Tsuna and his Guardians—minus Yamamoto and Chrome—along with the Ninth, his Guardians and the Varia, discuss the whereabouts of the Simon Famiglia's hideout. One of the Ninth's guardians discovers the location of the Simon base, via the private letter that Simon Cozzato sent to the Vongola Primo, Giotto. Tsuna requests for the Ninth's permission to allow him and his Guardians to invade the Simon hideout alone. Squalo protests, saying that the current situation is a mafia war – to which Tsuna replies that it is a fight for his friends. Timoteo agrees to let Tsuna and his Guardians to invade the Simon hideout, preparing three ships for them.
Tsuna and his Guardians return to the Sawada household to prepare for the assault. But on the way, Tsuna stumbles across Kyoko and Haru at a shop. Reborn asks him if he wants to greet them. Tsuna hesitates, unsure since he doesn't want to involve them in battle again. He gives the girls a silent goodbye and runs off to go to his house. Upon arriving, Tsuna discovers that he received a letter and package from the present Shoichi, who received memories of the future battles from Uni. The package contains the new headphones created by the present Spanner, who also received memories from Uni.
The Battles of Pride & The Seven Keys
Tsuna and the others arrive at the Simon Famiglia's Island. They are immediately greeted by the Simon Famiglia. Enma comments that Tsuna's Guardians arrived faster than expected and that they made the right choice to come alone, saying the island cannot contain mountains of corpses. The two Famiglias are interrupted by the Vindice, who claims to have come to fulfill the promise between Vongola Primo, Giotto, and Simon Primo, Cozzato. Because of Giotto and Cozzato's steadfast friendship, the Famiglias are forbidden to fight each other. According to the Vindice, this is the second time this law has been breached, and thusly, the Guardians must battle each other, with the loser imprisoned in the Vindice Prison forever.
Following this warning, the Vindice disappear. Without much of a choice, both Famiglias agree to fight. Adelheid explains that they seek only one goal, and Enma explains that the Simon Famiglia's history is engraved in the island. One by one, the Vongola Guardians must head for the goal, where Enma will be waiting. As Enma and his Guardians prepare to leave, Tsuna unleashes his Vongola Gear, challenging Enma on the spot. Enma smiles, commenting that Tsuna has grown more capable, and that he will await him with bated breath.
Ryohei Sasagawa vs Kouyou Aoba
- Battle Result: Draw
The First KeyAfter Ryohei and Kouyou collapse, Tsuna, Gokudera and Reborn rush to their side to provide medical attention. However, the Vindice intervene, declaring that since both combatants lost, they were both to be imprisoned in the Vindice Prison. Before being taken away, Ryohei explains that he had no regrets with following his pride to the end. When Tsuna exclaims that he didn't know if he had any pride Ryohei assures him that he had felt it and told Tsuna to find it and follow it. At that moment the Vindice drag him and Kouyou through a portal ignoring Tsuna's cries of protest. After this, the Vindice give them a small bag and tell them it is the first key that was entrusted by Giotto and Cozzato. Along with the bag, the Vindice show each of the members of the Simon and Vongola Families the memories of Vongola Primo and Simon Primo. Giotto is shown calling out to Cozzato, saying that he dropped his wallet at Paolo's shed. Cozzato replied that he intended to drop it because he could not stand to see Paolo and his family starve. Giotto revealed that he and G also did the same thing, leaving food for Paolo. Giotto, Cozzato, and G shared a hearty laugh, introducing themselves to each other and ending the memory. Somewhere inside a room, Chrome wakes up after seeing Giotto and Cozzato's memory. She sees a silhouette of a man resembling Mukuro standing by the terrace but it is revealed to be Julie Kato. Chrome asks Julie where she was to which Julie explains the situation. Chrome notices her trident lying on top of a dresser, and reaches out to grab it, but is interrupted by Julie, who offers her a new change of clothing, and even offers to help her change. Chrome refuses, but Julie is persistent. Adelheid then enters the room all of a sudden, informing Julie of a meeting with the other Simon Guardians. On the way, Adelheid comments that she will kill Chrome once she is no longer of use to them as a hostage. As Adelheid and Julie arrive at the meeting place, they discuss the battle between Kouyou and Ryohei, and also the memory given by the Vindice. Julie makes clear that he is uninterested, so long as they win. Julie turns to leave, but is stopped by Adelheid, who tells him that it is his responsibility to remain involved with the battle against the Vongola. Julie, visibly annoyed, grabs Adelheid's jaw telling her to keep quiet. However, Julie changes his demeanor, cheerfully stating that there is nothing to worry about, as he will help if things go bad.
Meanwhile, the Vindice tell Tsuna and his Guardians that the seven keys that were entrusted by Giotto and Cozzato, and, along with another memory, will be awarded upon another loss. Tsuna realizes that there will be a continuation of Giotto and Cozzato's memories, and as such, decides to follow through with the battles. On the way, Reborn realizes that Tsuna is still thinking about Ryohei and tells him if he gave up now, Ryohei's efforts would be wasted. Tsuna says that he didn’t even know his own pride but Reborn tells him that he can figure it out later, for now concentrate only on winning to save Chrome and reveal the truth behind Giotto and Cozzato. Noticing that it is almost dark, Tsuna and the others decide to camp. While they are asleep, Lambo is awakened by a rabbit in front of him and chases after it, falling into a pitfall. Tsuna and Gokudera also fall to the pitfall and find themselves in a cave surrounded by rocks. In the middle of the cave, Lambo encounteres Large.
Lambo vs Large Ooyama
- Winner: Lambo
The Second KeyWhile everyone congratulates Lambo for his victory, Large begins to yell that even though he lost, Simon will never lose because Enma will avenge him. He explains that Enma is a better boss than Tsuna because he protects his family from the ally families of the Vongola who killed the current Simon Famiglia's parents. The Vindice then appear behind Large and chain him as they give them a flower that is the second key left by Giotto and Cozzato.
The Vongola and Simon begin to witness again the memory of Giotto and Cozzato. At some poor town in Italy, Giotto, G, and Cozzato arrived at a flower shop that was attacked by some thugs because the owner, Franco, refused to gave them 90% off and all doctors in town were threatened by them and didn't show up. This angered Giotto who stated that he had enough already. Cozzato then suggested forming a Vigilante group because if nobody can help them, they have to protect the town themselves with a powerful leadership with no one else beside Giotto who would be suited for that role.
After they witness the memory, they are shocked to find out that it was Cozzato who suggested forming the vigilante group that became the core of the Vongola Famiglia. Large shows his disbelief but Gokudera interrupts that only a great person will be chosen as Vongola and pointed out that Large himself was beaten by one of the Vongola guardians. This angers Large and he then asks Lambo if Tsuna is a good boss, which Lambo answers that he never thought of Tsuna as his boss, however, he states that Tsuna is a great Brother. Before Large is taken by the Vindice, he states that he could never forgive the Vongola but he accepts Lambo, saying that it was fun. Lambo then turns back to his younger self and Tsuna and the others are relieved that he won the match. Back at Japan, at Namimori hospital, Byakuran comes to the unconscious Yamamoto on the hospital bed with his wings spread out open.
Later, at Simon's meeting room, Julie comes and playfully says that he heard Large was defeated, this makes him get scolded by Adelheid. Julie then comments that Kaoru will not fight since he had beat up Yamamoto before the ceremony. Adelheid then asks if he got any new information from their spy but Julie replies that they didn’t have any information for him. He then drags Enma to drink some coffee with him so he'd be able to relax. In a different room, Julie then reveals that he actually did get some information from the spy and tells him about CEDEF being the key of the past of their ancestor and shows him a picture of Tsuna's father, Iemitsu. This enrages Enma even more and Julie convinces him that Vongola Primo was a cunning man and already planned all this from the very beginning and tells Enma to see the Vongola as the absolute enemy, which Enma agrees to. Julie then thinks that all is going according to his plan.
Tsuna, Gokudera, Lambo, and Reborn continue their way to the Simon's hideout and reach a deserted, rundown town. When they check the town, they hear a voice from one of the houses that turns out to be Shitt P! who is writing her homework. When Gokudera calls her, she just ignores him until he calls her by her preferred name, "Shittopi-chan" and she finally responds to Gokudera's call, much to the surprise of Tsuna. She then challenges Gokudera to fight one-on-one with her which he agrees to since he was interested in fighting a UMA. When Gokudera is about to tell her his pride, she cuts him off and instead reveals his pride herself, that Gokudera's pride is being a subordinate of the Vongola tenth, which Gokudera admits to. At this, Shitt P! comments that Gokudera is weak and reveals her pride is fighting for herself since she loves herself more than anybody else. Gokudera then summons Uri who is seemingly tamed but then slowly begins to scratch his face until Gokudera orders Uri to Cambio Forma and reveals his Vongola Gear, creating the revival of his former title, "The Smoking Bomb."
Hayato Gokudera vs Shitt P!
- Winner: Gokudera
The Third Key
The Vindice then appear and give the third key which turns out to be a letter. The flashback shows that Cozzato received a letter from Giotto that told him about the Vongola Famiglia that had grown so big that even the police couldn't interfere. However, Giotto worried because many people feared the Vongola and the biggest war ever will coming up soon and requested for Cozzato's help. After reading the letter, Cozzato decided to help Giotto and said he will come soon. After this flashback, Shitt P! comments that because Cozzato fought for Giotto and was betrayed by him, she decided to live for herself. She was bullied by others and after some time she assured herself that she was right to act as an individual. She then calls Gokudera an UMA, much to the shock of the others but also says that he is interesting and she wishes to know more about him.
Tsuna then interrupts stating that he will save Ryohei and also the other Simon Guardians that were being imprisoned in the Vindice Prison, much to the shock of the others and even Tsuna himself who wonders why he said that. However, Enma then comes and says it's none of his business and intends to help Shitt P! but the Vindice still take her with them, saying that they won't let anyone interfere. Before being taken away, Shitt P! says that Enma is kind and she was glad she joined the Simon. Enma then unleashes his Simon ring power with teary eyes, blaming Tsuna for the loss of his friends and everything precious to him. Adelheid and Julie arrive at the scene. Adelheid tries to stop Enma but is stopped by Julie who says that they should let him go. Enma then declares that he will defeat Tsuna right here and right now.
Tsunayoshi Sawada vs Enma Kozato (Round I)
- Battle Result: Enma's ring out of control and he retreats along with Adelheid and Julie.
Demon Spade's Revelation
Back at the Simon hideout, Chrome attempts to escape but Julie has already arrived back there and laughs at her futile attempt. He then says that they get along quite well, a whole lot more than Mukuro, and also knows about Chrome's past. Chrome is surprised and asks how he knows about Mukuro. He begins to reveal that the island has a special defense structure in place and Mukuro's illusions cannot reach her. The reason that Chrome's organs were still functioning well was that he was the one who created them in place of Mukuro. Chrome at first doesn't want to believe this, stating that she received the body from Mukuro. Julie then tests it by making her organs disappear, which they do, making Chrome's stomach sink and making her cough blood. He tells her that the reason he went that far to help her even though they were enemies was that both Chrome and her body are important to him and then he recreates her organs. Julie then offers her to become his, which Chrome quickly refuses and says that she doesn't need the organs that he made, which surprises Julie and he decides to tell her his secret.
He was the one who devised the entire war between the Vongola and the Simon for two goals; first to annihilate the Vongola which Enma and Adelheid were already doing their best to accomplish, and second is to use Chrome as his entrance to get to Mukuro and take his body. Julie then dismisses his illusions and reveals his true identity as the First Generation Vongola Mist guardian, Demon Spade and shocks Chrome greatly. He requests Chrome to submit her body by her own will but Chrome refuses again and gives Demon no choice but to punish her and proceed to use his right eye that reveals a spade symbol, controlling her mind to make her obey to him.
Back at the Vongola ship, Timoteo asked Ganauche if there is any news from Tsuna, to which Ganauche replies that there isn't. Ganauche then suggests for Timoteo to sleep since he hasn't slept for four days but Timoteo refuses and instead asked about the condition at Namimori hospital but is then interrupted with the arrival of Nie Brow Jr. who has information regarding the Simon Famiglia. He says that all seven members of the Simon had their families killed when they were still very young.
Timoteo then asks if they were persecuted or not, when Nie Brow Jr. says that many cases existed, Timoteo interrupts by saying that he asked whether they truly persecuted or not. Nie Brow apologizes and promises to speed up the information but then says that something was different regarding the cases of Enma's parents and sister. Timoteo asks what that means and he is reminded about the "Flood of Blood" incident that occurred under CEDEF, which surprises Timoteo as he remembers and is in utter disbelief.At Enma's room, Enma dreams about his sister while Adelheid stays by his side as she wonders how Julie got the information regarding Enma's Ring Holders and as she remembers the past, he was not the kind of person who would agitate Enma this much. Before she leaves, she assures Enma that she will purge the Vongola.
On the way to the Simon hideout, Lambo asks Tsuna to play with him since he was silent all the way due to the shock he received when Enma revealed to them about his father. Suddenly, a helicopter appears and flies away and Gokudera uses this to cheer up Tsuna but fails. Tsuna then finally speaks, he isn't sure if he is doing the right thing anymore because he thought that Enma isn't lying since he could feel his sorrow and sadness through his fist. Reborn then comments that he also thinks that Enma isn't lying but he also said that even though what Enma said was true Reborn wonders if the Simon really wanted things to turn out this way as he said that when Enma attacked them, something didn't feel right, suspecting there's a dark shadow behind the Simon.
Meanwhile, at another room in the Simon hideout, Chrome changes her clothes to the Simon Middle School uniform. Demon then appears as he comments that the uniform suits her well. He changes back to Julie as he says that he wants to quickly get used to controlling her mind so she should be by his side all the time.
Kyoya Hibari vs Adelheid Suzuki
- Winner: Kyoya Hibari
The Fourth Key
The Vindice appear to arrest Adelheid and to give the fourth key, an inkwell. The fourth key shows Giotto and the others in the middle of a meeting regarding the massive mafia war they were in. Knuckle suddenly enters and informs his fellow Guardians that the Simon are surrounded by enemies from all four directions and are at the center of the enemy's camp. Giotto who is bewildered by this information is confused as to how Cozzato came to know of the war, and intends to rescue his friend without hesitation. However, Demon Spade assures the Primo that he will be the one to assist the Simon, which Giotto accepts and is relieved by. When the memory ends, everyone realizes that someone has set a trap for Cozzato, since Giotto had never spoken of the Vongola's war to Cozzato. Hibari then realizes someone is watching them and throws his handcuff towards the figure who reveals himself to be Julie along with Chrome. Adelheid asks Julie to take care of Enma, to which Julie agrees but then continues by saying that from now on he will leave his place in the Simon Famiglia.After Reborn refers to him as the dark shadow of the Simon, he finally reveals himself as Demon Spade, much to everyone's shock. Reborn is suspicious of whether or not he is the real Demon Spade or not, to which Demon replies by saying that whether they choose to believe or not, he exists. When Tsuna asks why he's done all that he has, Demon simply answers it is all for the sake of the Vongola. He states that Giotto was a great leader but lacked ambition in the mafia world, where power and greed are the only absolute justice. He continues, saying that with Giotto's nature it would have been impossible to create the flawless Vongola Famiglia and therefore, he would do anything necessary to eliminate anything and anyone that will weaken the Vongola—just like Cozzato and the Simon whom he saw as a threat. Thus, admitting that he was the cause of Simon Cozzato's death. Demon tells of how he used the Simon's dormant power amplified by hatred in order to try and eliminate the tenth boss candidate who would try to succeed Primo's will. This angers Adelheid who then realizes that Julie must still exist and demands from Demon where he is and what he has done to him. However, the first Mist Guardian answers that there is probably a slight bit of "that garbage" left inside him and Adelheid tearfully apologizes to Enma. Demon comments that the Simon are a bunch of inexperienced children after all. However, at this moment, Kaoru appears and stabs Demon from behind.
Vongola & Simon vs Demon Spade (Round I)
- Battle Result:
- Kaoru loses his pride before the fight and is taken away by the Vindice along with Adelheid.
- Demon withdraws from the battlefield with Chrome after a brief fight with Yamamoto.
The Fifth KeyAnother Vindice appears behind Kaoru and arrests him, stating that Kaoru already lost his pride before the battle could even start, thus, making him the loser. Kaoru explains that his pride was to do anything for the sake of the Simon. However, to betray Yamamoto, who he sees as his friend, is unbearable to him and he wants to pay for the crimes he has committed and apologizes to Adelheid, for he no longer has any capability to fight the Vongola. Demon mocks him as trash and useless and then says that thanks to his loss, they are finally able to see a fantastic show. The fifth key is revealed to be a document with a Dying Will Flame on it. Demon states that the next memory that will be shown is the last moments of Cozzato, who fell into his trap and was killed, his limbs pulled off one by one until his death.
The fifth key shows Demon along with his subordinates, who have found Cozzato's location. Knowing how persistent Cozzato is, he hands his subordinates a letter with a Dying Flame signed on it to trick Cozzato and the others so that he could kill him when there's an opening. After this, Demon went back to Vongola mansion, pretending that he was beat up and his subordinates were killed and lies to Giotto that Cozzato was already dead, which upset Giotto and replies that Demon has done a good job and he's at his debt
At Simon's place, which was surrounded by enemies, Demon Spade's subordinates arrive, saying that they have come to help them. However, Cozzato knew that they were sent by Demon to kill him, since he knew that the third letter that he received was fake because the letter was signed "from Primo" and Giotto would never refer himself that way to him. Cozzato turns into Hyper Dying Will Mode, stating that he will fight until the end for his friends and his Famiglia. At this, Demon Spade's subordinates tear apart the letter and reveal themselves as G and the other Guardians that were ordered to assist them by Giotto, who had seen through Demon Spade's plan. G assures Cozzato that the men with him are just like him, Giotto's guardians, and that they can be trusted. G explains that they could've gone all out but they didn't want Demon to know that they were saving him and told Cozzato the four guardians would fight the enemies, while he and Cozzato would go to Giotto. Before they go, Cozzato thanks G and the others. As the memories ended, which revealed that Cozzato had not been killed, it shocks all of the participants, especially Demon, who then shouts in disbelief that Giotto had saw through his plan. Reborn said that it seems the history of the Simon has been rewritten. Tsuna happily exclaims that Giotto never betrayed Cozzato and that their friendship never wavered at all. Demon furiously curses Giotto, who had faked Cozzato's death, but is interjected by Reborn who wonders if Cozzato had never been assassinated, then why are there no lying records of him afterwards, much to everyones confusion.
Simon Rings Awakening
Demon, disguised as Julie, approaches Enma at his throne and informs him of Kaoru and Adelheid's losses the at Vongola's hands, enraging Enma further who is then finally consumed by his own hatred. Satisfied that now Enma has completely become a killing machine, Demon changes back and leaves the task of defeating Tsuna and his friends to him.
In a circular building, Demon approaches Chrome, whom he had tied up and undone his mind control on her. He assures her that he will let her meet Mukuro, explaining that he will remove the barrier that is surrounding Simon Island so that Mukuro can come to save her and he'll be able to fight Mukuro with the awakened Simon Desert Ring. Demon removes the barrier and Chrome's illusionary organs, taunting Mukuro that Chrome will die if he doesn't come to save her. Shortly, as he has expected, Mukuro replaces Chrome and declares that he will take Demon to the realm of the dead.
Tsunayoshi Sawada vs Enma Kozato (Round II)
- Winner: Tsuna, Enma is allowed to watch the battle until the end before being imprisoned.
The Sixth KeyAfter explaining Demon Spade's plot, Enma offers to help them to save Chrome, much to Tsuna's happiness and he agrees. At this, Reborn comments that both Tsuna and Enma will be a perfect No-Good combo and Lambo adds that Tsuna is greater No Good out of the two. This causes brief laughter that is soon interrupted by the arrival of the Vindice who decide that Enma is the loser of the battle. Tsuna tells them that there's no need for any fight anymore because they no longer have any ill feelings towards each other. However, the Vindice states that the battle will continue until the end because that is the law that had been decided by their ancestors and present the sixth key, which is a clear pacifier.
The memory reveals that Cozzato requested for Giotto to keep the lie that the Simon Famiglia had been killed as the truth. Cozzato explained that he had a strong feeling that it won't be a simple task to eliminate Demon Spade and if Demon continued living, the Simon would only be a burden. Therefore, it would be better if Simon just went into hiding and disappeared from the mafia world and any view, much to Giotto's protest. However, Cozzato insisted and convinced him that the Simon are not weak. At this, Giotto reluctantly agreed but not before he asks Cozzato to swear in return that the Vongola will always support the Simon from the shadow and their bonds will stay close until the end of times. As Cozzato swears this, Bermuda von Veckenschtein, an Arcobaleno with a clear pacifier and a Vindice appeared, intent on upholding the law.
As the memories ends, Reborn questions why the Vindice possess the clear pacifier. When the Vindice refuse to answer this, Reborn groans, making Tsuna surprised to see for the first time Reborn being bothered by something this clearly.
Mukuro Rokudo vs Demon Spade
- Winner: Mukuro
Demon purposely lost the battle with Mukuro and manages to possess Mukuro's body and frees himself from the Vindice Prison. The Vindice negate the war between the Vongola and Simon and strike a deal with both Families that if they are able to defeat Demon, the imprisoned Family members will be released. Demon arrives on the battlefield and is ready to fight Tsuna and his Guardians one last time.
- Winner: Tsuna
The Seventh KeyThe key reveals Giotto, Cozzato, and G, met face to face with Bermuda von Veckenschtein, the Arcobaleno carrying a clear pacifier who claimed that if the Vongola and Simon ever fight one another, they would deliver the punishment. Giotto objected, saying that it has nothing to do with them. The Arcobaleno retorted and replied that the destiny between the Vongola and the holder of Arcobaleno pacifiers would always be intertwined, much to Giotto's confusion. Cozzato agreed since he believed that their children won't fight against each other. The Vindice revealed that they will imprison the losers until the day they die. Giotto finally agreed with one condition: After each battle, he wishes for their true history to be shown. Cozzato added that if the each sides still cannot let go of the enmity between them even after knowing the true history, the Vindice are free to do anything to them. However, if both Families reconcile and regain their friendship, if they honor their will, they have to have their Flames within the rings burn as one as evidence of their will to keep the promise.
Tsuna picks up Demon Spade's pocket watch with an old photograph of Vongola Primo's Guardians with a beautiful woman beside Demon. The dying Demon tells them that the woman was Elena, his lover. Demon begins to tell of his past and his reason behind all of his actions, revealing that it was all for Elena's sake who loved the Vongola Famiglia more than anything. Tsuna wonders out loud does Elena truly love the Vongola that Demon had made since it controls people through fear without taking the feelings of the weak into consideration and tells Demon that he understood Elena's feelings when the latter questions him. Tsuna assures Demon that Elena feels gratitude towards him and she thanks him. Demon cries as he pleads for Elena's forgiveness for being unable to save her and starts to fades away. Reborn convinces him to leave the Vongola to Tsuna, and Demon finally acknowledges Tsuna and his Guardians, entrusting the Vongola to them and finally dies in peace. The trapped Vongola Guardians and Julie, along with the imprisoned Simon Guardians and Ryohei are freed and each of them reconciles and Mukuro is taken back to his own body. The Vindice then reveal that they still have one final thing to tell them.
After the battle between the Simon and Vongola ends, Tsuna returns to his normal life at Namimori, rushing to get to school to not get scolded by Hibari, but finds Enma on his way running away from a dog. The two rush across a road and meet up with Shitt P! who is stalking Gokudera, who calls her a freak and runs off in another direction. The No-Good Duo finally reach the gates of Namimori where they encounter Large and Lambo, who had been staying up and playing. Large told them that the inspection by the disciplinary group was postponed since Hibari went to Kokuyo Land to fight Mukuro.

The Eighth Key
The memory begins with a sight of Cozzato's Famiglia's children playing in the river and eating. Then, a little girl called Magi approaches Cozzato and asks if she could have more friends, Cozzato says that she'll have to wait a while. Then a man resembling Julie states once the situation is cooling down they can invite the Vongola Family to their island; however, Cozzato says that they'll never be able to see the Vongola ever again, and that Giotto knows that fact too. But they believe in each other, so that someday, their descendants could finally meet and smile again with the Vongola. Tsuna and Enma laugh together as they remember this, ending the Inheritance Ceremony Arc.
