Reborn (リボーン, Ribōn) is the eponymous character and deuteragonist of the series of the same name. While seemingly appearing to be a baby, he's actually holds the title of the world's strongest hitman and is a well-known for his ties with the Vongola Family. After an encounter with a man in an iron hat, he's cursed with the Sun Pacifier of the Arcobaleno.
Reborn is a small infant, he's slightly tanned with black spiky hair, and thin curly sideburns. His main outfit is an all black suit, with a red long sleeved shirt and black necktie from underneath, and a black fedora with an orange stripe, his fedora seems to contain all of his hair. He is always seen with his pet chameleon Leon, on the brim of his hat, along with his his Sun Arcobaleno Pacifier
While in his adult form, he wears a yellow long sleeved shirt instead, and his blazer is changed to a sweatervest in some promotional images.
Reborn has also worn many various costumes that vary in design and creativity, which are often very easily able to trick others into believing that he's a different person, except for Tsuna who can easily see through his costumes.
Among all the Arcobaleno, he is said to be the strongest. It was revealed in a flashback that Reborn initially showed anger towards the Arcobaleno curse; however, after a period of exile, he came to accept it, asking Shamal to "erase" his old self. As an Arcobaleno, he remains fairly calm through any situation and always putting a straight face, even in his "fights" against Colonnello. He also is rather sadistic and likes to occasionally tease his students, much to both Dino's and Tsuna's dismay. He did, however, admit to have snapped when Timoteo was revealed to be in Gola Mosca during the Varia Arc, and was also shown to be enraged when he could only helplessly watch as Tsuna was being beaten up by Daemon.
Reborn's past is shrouded in mystery, though it can be assumed that at some point in his life he had built the reputation as the world's strongest hitman, which had happened even before he met his fellow Arcobaleno. He was said to be quite close to first Arcobaleno boss, Luce, and at an unknown point in time, he began working for Timoteo.
During an unknown point in his life, he became a famous mathematician, going under the name "Borin", and solved math problems that were previously considered impossible. Though, it's also possible that his "Borin" persona could have been a look alike.
Reborn is introduced as Tsuna's home tutor after Nana found his flier. He then reveals to Tsuna his true intention and Tsuna's relation to the first Vongola Boss, helping him to befriend Kyoko in process.
Throughout the arc, Reborn mostly takes a mentoring back seat in the arcs, rather than the direct fighting; however, he can be credited with helping Tsuna achieve much higher levels and gain new, more powerful attacks. And he is shown wearing many costumes and appearing in his many hideouts. He is a known celebrity at Mafia Land.
Before he learns of the seriousness of the attacks, Reborn, along with Nana encourages Tsuna to learn how to defend himself. But when he and Tsuna visit the hospital after Ryohei falls prey to the attacks, he discovers the watch. When Leon's tail falls off, the severity hits him. He reads Tsuna the letter he received from the Ninth, and opts to gather a group to do battle with Mukuro's gang.
Kokuyo Land Invasion
Bianchi, Yamamoto, and Gokudera join Reborn and Tsuna as they begin their offensive. During Takeshi's bout with Ken, he kicks Tsuna into the Botanical Dome because he expressed concern over Takeshi. He helps the two out of the hole after Takeshi wins the fight and accompanies the group to a rest area, where he sleeps through the encounters with M.M. and Birds. When Reborn awakens, Tsuna runs off to go and pursue Fuuta, and the rest of the group stays behind to take on the next killer, who turns out to be the Fake Mukuro. When Gokudera is temporarily incapacitated by Shamal's Trident Mosquito side effects, he watches as Yamamoto takes on the Fake Mukuro. He and Takeshi simultaneously figure out and reveal the trick of the Steel Serpent Ball. But, it wasn't enough for his future pupil to win. As Bianchi steps to the plate to fight next, and is nearly pulverized, Reborn shoots Tsuna with the final Dying Will Bullet just before he catches the weapon. Reborn looks on as Tsuna takes the win, and as Lancia reveals that Mukuro is actually still up ahead.
Reborn is forced to condone leaving Gokudera behind to take on Chikusa and supplies Tsuna with the whip Dino gave him. He mainly observes as Tsuna frees Fuuta from possession and gains his new X-Gloves to battle with Mukuro, only intervening when Tsuna panics in the midst of the fight, and he has to talk some sense into him.
Reborn, during the down time between Ring Battles, trains Tsuna on how to use the Dying Will Zero Point Breakthrough in order to take on and defeat Xanxus. However, when Hibari returns from training after Hayato's Storm Ring Battle, to bite everyone-Varia and Tsuna's Family- to death, Reborn placates him by promising that he may be able to battle Mukuro again, which greatly pleases Hibari. For the remainder of the Arc, Reborn has a mainly static role of training and commenting. He lastly shoots Tsuna at the start of the fight when Xanxus tries to gain a cheap shot before the match starts and watches as Tsuna's Family proves victorious in the Sky Battle.
Arrival & The Search for the Strongest
Reborn is the first to be transported to the Future and trapped there. It is not yet revealed how he found his way to the Vongola Headquarters, but he is next seen greeting Tsuna and Gokudera as they arrive there with Lal Mirch, though he has to wear a special suit to keep from being killed by the anti Tri-ni-set radiation that Byakuran is pumping into the atmosphere. The anti Tri-ni-set radiation affects the Arcobaleno severely, paralyzing their movement and killing them slowly, but it does not seem to have an effect on normal people. Reborn reveals to Tsuna that he needs to gather all seven of his guardians to do battle with Byakuran's forces. Reborn doesn't venture out of the base at all during this plotline due to the radiation. He does, however, help Tsuna with his training after he returns with Kyoko, Haru, I-Pin, Lambo, and the Yamamoto from 10 years ago by getting Tsuna to realize what his true goals are, which were to "protect everybody," not "to return to the past."
Merone Base Invasion
Reborn appears after Tsuna is captured by Spanner as a hologram projected by Tsuna's headphones and witness to Spanner instructing Tsuna on how to use the contacts to perfect his X-Burner. He remains with Tsuna for the rest of the invasion, and gets Giannini to program a holographic distraction during Tsuna's fight with Genkishi. When Shoichi Irie reveals that he is an ally of the Vongola, Reborn believes him, mostly because he answered the questions that Reborn had being thinking about since he was sent to the Future.
As Tsuna and his Family are sent back to the past, Reborn tells them the few Abilities and characteristics of the Arcobaleno. He also remembers that the current Sky Arcobaleno is missing, which may become a predicament for Tsuna in the Future Trials. He also reminded Tsuna that he is also an Arcobaleno, in which he says that he would not hold back during the Trial.
During Reborn's Arcobaleno Trial, he informs Tsuna that his Trial was a seven-on-one, all-out battle with him, and that all six of the Guardians, including Lambo, were to participate. He knocks out Tsuna and takes down Hibari, Chrome, Ryohei, Gokudera, and Yamamoto. When Tsuna finally comes to, the sleeping Lambo is the only one who was in a good condition.
Tsuna at first does not want to fight Reborn, but Reborn tells him that he's still "too soft" and that his fallen comrades are his responsibility. Tsuna finally accepts this and enters Hyper Dying Will Mode and fights Reborn. Reborn allowed himself to be beaten into a wall but Tsuna stops as he is about to use his X-Burner and gets shot down by Reborn's Chaos Shot, who said "I cannot pass a person not fit to be Boss."
He gets captured by Verde, along with all the other Arcobaleno besides Aria, using a variation of anti Tri-Ni-Set waves, which only paralyzes them, as opposed to outright killing them. After Verde's trial, he was asked for a second chance at his trial by Tsuna, but he said that it wasn't necessary. He states that they completed it in their fight with Verde.
To prepare for "Choice," the war game that Byakuran is making the Vongola Guardians play, Reborn asks Shoichi to explain the rules. While he finds the game tasteless, he has great faith that the technicians will come up with solutions for the problems they will be facing. One of their solutions was to make the Guardians ride Motorbikes for extra mobility. When explaining to Tsuna how to ride, he instructs Tsuna to pop the clutch without Tsuna realizing that it was wrong. Reborn's reasoning is that Tsuna should get the worst parts over first that is his tutoring method.
When Dino arrives at the Vongola Headquarters and assigns the Guardians their tutors, Reborn assumes the role of "Tutor Fairy," mostly likely only so he can discipline Dino if he makes any mistakes.
Reborn is present during Yamamoto and Hibari joining the group in the moments before Choice begins. He sees them all unleash their Vongola Boxes and generate twice the amount of FVs needed to transport them- a whopping 10 million. He is engulfed in a beam of light along with everyone else present.
He wakes up in the Lightning Field that Tsuna selected, and listens as Byakuran explains the rules of Choice more clearly. Reborn, along with the rest of those chosen to sit out of the first battle, relocate to the Vongola Audience Stalls to watch the battle of Tsuna, Gokudera, Yamamoto, Shoichi, and Spanner for the Vongola versus Kikyo, Saru, Torikabuto, and Daisy for the Millefiore under the Target Rule.
Later, he protects Yuni from Byakuran by shooting him, saying that if he lays a finger on the Arcobaleno Boss, he won't sit back and watch.
Seeing that Tsuna and the others need to become stronger, Reborn arranges to have them sent back to the past. While in the past, Reborn gathers the other Arcobaleno to train Tsuna and his friends. He is also the one who explains to them that they will be tested by Vongola Primo's Guardian. Reborn will train Ryohei, as they both have Sun Flames.
Reborn begins to stay to Ryohei's and Kyoko's house as being Ryohei's temporary tutor.
Reborn was an audience to Yamamoto's trial.
It was stated by Reborn that because Lampo hid inside a castle inside the amusement park and the only objective was for Lambo to acquire three stamps and go to him, it shows his obvious distaste for Lambo and the fact that he had not prepared beforehand. He goes to the amusement park with Lambo, Tsuna, Gokudera, and Yamamoto. Verde finally shows up himself, after sending all sorts of tests on Lambo and defeated by Lambo's Elettrico Cuoio. Reborn chides the defeated Verde and tells him that he is a tutor and should not do this to his student.
During Gokudera's trial, Reborn is seen sitting on Namamori School roof top discussing with Fon, Collonello and Skull on their counterpart students. Skull tries to brag about him and Hibari, but the rest of the Arcobaleno there ignores him. As Skull repeats his sentence many more times, Reborn calmly takes Skull and throws him off.
During Hibari's and Ryohei's trial, Reborn tricks Skull into taking action on Hibari. When Skull tries to attack the school, he tells Tsuna, Gokudera and Yamamoto not to interfere with Hibari and Ryohei arguing and later, defending the school. Eventually, Reborn told Yamamoto to tell the first-year base ballers to evacuate from the school.
After arriving back with the rest of the gang from the past, Reborn tells Tsuna that they do not have much time before the Real Six Funeral Wreaths appear from the teleportation system. Soon after Giannini gets the alert that they have arrived, Reborn goes and inform the rest.
He flees the Vongola Base together with the rest as Squalo tries to buy time by fighting with Zakuro. Upon hearing Haru's suggestion of a hideout, he decides to agree into hiding at the place Haru knows of.
Upon reaching the place, which turns out to be Adult I-Pin's ramen customer's place, (uncle) Kawahira suspiciously tells them that he knows what is going on and they can trust him on luring away Zakuro. At first, Reborn was suspicious but decides to trust him. When Kawahira uses his Segno Hell Ring to create fake killer intent to lure Zakuro away, Reborn starts to ponder who exactly Kawahira is, he is being able to create strong illusions too.
When Kikyo, Bluebell and Zakuro arrives to take Yuni away, Reborn joins in Gamma and Tsuna in defending Yuni. Reborn sits on Basil's Alfin to travel to the air to help out, shooting at Kikyo, tell him that the Vongola do not fight alone but as a team. With that inspirational sentence, the rest of the Guardians become prepared to fight against Kikyo, Bluebell and Zakuro. Kikyo decides to retreat, leaving Reborn and the others behind.
Fleeing into the forest according to Yuni's suggestion, he tells Tsuna that he has to come up with a plan to continue protecting Yuni from Byakuran. After seeing the slight conversation between Yuni and Gamma, Reborn decides to talk to Gamma about his feelings for Yuni. As Gamma and Reborn walk away from the camp, Reborn tells Gamma that he should stop treating Yuni like a child and admit her feelings towards him.
When the 7³ set ring bosses, the Mare and the Vongola calls, Yuni's Sky pacifier resonates and she floats upwards. Determined to protect the Arcobaleno's boss, Reborn tries to break the barrier around Yuni, only to get deflect off.
Reborn gets a notice from the 9th Boss that the inheritance ceremony would start in a week's time.
Investigating the Simon Famiglia
Reborn, getting suspicious, uses the opportunity on the Simon Famiglia guarding Tsuna to test Koyo Aoba (since it was his turn). Just nice, Ryohei appears at Tsuna 's house, following Koyo's taunts on a piece of paper. Upon Nana's suggestion, he decides to give the friendly rivals a study test (which they share the hatred of studies, both being 'idiots'). He gives them an easy test written on extra hard plates. He slyly tells them that if they manage to break the plates, he would have to postpone the test. He watches over the duration of the two spending time in Tsuna's room. When Tsuna's room explodes, he rushed up with the rest to see the plates broken by Ryohei's Maximum Cannon. He was impressed by Ryohei's strength, but was more shocked by Koyo being able to withstand Ryohei's Maximum Cannon without receiving any injuries.
Arrival at Simon Famiglia Island
Reborn arrives at the island with Tsuna, Gokudera, Lambo and Ryohei on the Ninth's boat with his guardians. He debarks with Tsuna and his remaining guardians to the island. When Tsuna activated his new Vongola Gear when the Simon Famiglia arrived, Reborn felt that Tsuna feels different.
Ryohei Sasagawa vs Koyo Aoba
Reborn, together with Tsuna, Gokudera and Lambo could only stand at one side and watch the fight between Ryohei and Koyo.
After Ryohei and Koyo collapse because of the severity of their injuries, Tsuna, Gokudera and Reborn rush to their side to provide medical attention. However, the Vendice intervene, declaring that since both combatants lost, they were both to be imprisoned in the Vendicare Prison. Reborn doesn't receive the memories contained in the First Key.
Hayato Gokudera vs Shitt P.
After the Vindice take their leave, Reborn with Tsuna, Gokudera and Lambo carry on walking on the road. Soon, they reach a town which looked like the town Giotto and G. met Simon. There, they meet P.Shitt. Reborn observes the battle between P.Shitt and Gokudera. He was impressed when Gokudera wasn't disillusioned on Tsuna and still insists on becoming Tsuna's right-hand man, trying to live it up to G.
Tsunayoshi Sawada vs Enma Kozato
Shortly after Shitt P's, defeat, Enma furiously ambushed Tsuna, forcing Tsuna to fight back. However, Enma then revealed that Iemitsu was the one who killed his family, shocking Reborn, Tsuna, and Gokudera. This revelation caused Tsuna to lose his will to fight and nearly killed if Enma's Simon Ring didn't lose control. This made Enma has no choice but to retreat. Reborn immediately approach Tsuna, asking whether he is okay. Seeing Tsuna didn't respond to his question, Reborn kicked him to get his attention, but realised that Tsuna was too depressed by the revelation.
Kyoya Hibari vs Adelheid Suzuki
On their way, Reborn states his suspicion of Enma's sudden attack and suspected that there's a possible black shadow that controlling the Simon from behind the scene. Reborn further comments that Simon is not monolithic, angering Adelheid who overheard it. He, Tsuna, Gokudera, and Lambo then watched her battle against Hibari, which resulted with the latter's victory. Once receiving the fourth key, Reborn concludes that there's someone who wanted Cozarto to be killed by sending the fake letter to him. This proven to be true when Julie, who revealed himself to be Daemon Spade possessing Julie's body, admitted himself to be the culprit behind everything that had happened.
At this revelation, Kaoru attacked Daemon, but later turned out the one he stabbed was an illusion created by Daemon, who stabbed back Kaoru from behind. To prevent Tsuna and his friends attacking him all at once, Daemon ordered Chrome to trap Tsuna, Gokudera, Hibari, Reborn, and Lambo with her mist barrier, preventing them from interfering. Yamamoto then arrived to save Kaoru, with the latter being imprisoned by the Vendicare since he had lost his pride, allowing them to witness the fifth key that shows Cozarto and his Family survived from Daemon's scheme thanks to G. and the other remaining Guardians who was sent by Giotto after realising Daemon's plan. This revelation shocks everyone and makes Reborn wonder why there's no clue about Cozarto's survival.
After Daemon and Chrome decided to retreat, Reborn asked what Tsuna will do regarding Iemitsu killing Enma's family, which Tsuna answered that he will believe in his father.
Tsunayoshi Sawada vs Enma Kozato (Rematch)
At Simon Castle, Tsuna confronts Enma who was too overwhelmed by hatred, leading him no choice but to fight him. After much struggling, Tsuna able to save Enma from his out control Flame and received the sixth key, which is a clear pacifier that shows Cozarto decided to hide within shadow to fool Daemon and swore to Giotto that the Simon Family will always be there to support the Vongola. The oath made by the two bosses led a Vendicare with a baby who holds the clear pacifier to appear before them to uphold the mafia law. Reborn immediately asked where the Vendicare got the pacifier, but they refused to answer.
Tsuna & Enma vs Daemon Spade
Reborn and the others went to the circular building where Mukuro is and finds him apparently already defeated Daemon. Unfortunately, this turned out to be planned by Daemon, who lost on purpose in his battle against Mukuro so he can possess Mukuro's body in the Vendicare Prison before Mukuro could return. The Vendicare appears and tells that Daemon has staged a prison break and since Daemon's actions are based on his dedication for Vongola, the Vongola must be the ones to defeat him in exchange they will free Ryohei and the other Simon Guardians.
Daemon reappears, powering up with the five Simon Rings he has stolen from the prison, trapping Gokudera, Lambo, Yamamoto, and Julie inside his illusionary worlds in the process. Hibari challenged him to a one-on-one fight, which led to Hibari be trapped as well. Tsuna and Enma decides to fight together and with Chrome and Mukuro's help eventually able to blast Daemon with XX-Burner. However, it turns out Daemon barely survived the attack and proceeds to crush Tsuna's bones to pieces. This angered Reborn who wished to help his student, but the Vendicare threatened that if he interfere, they will be his opponent.
Just before Tsuna was killed, Enma's Simon Ring merged with Tsuna's Vongola Ring, granting Tsuna the power strong enough to defeat Daemon.
Reborn is shown to be having a dream of the time when a mysterious man gathered the "I Prescelti Sette", the aforementioned group becoming the Arcobaleno as a result. In the dream, he recalls the experience, but is suddenly turned back into his infant body. The mysterious man that gathered them reveals himself and presents them with the opportunity to turn back into their adult forms with a competition, where the strongest Arcobaleno's form will be reverted. Reborn resisted at first, but after his Arcobaleno colleagues all agreed, agreed as well. Later, he asks Tsuna and Dino, explaining the curse of the Arcobaleno after they agreed to fight for him. Reborn is then seen the next morning walking with Tsuna to school, while the Kokuyo Gang shows up, Verde revealing himself and the fact that he asked them to fight for him, causing Reborn to mentally comment that Verde and Mukuro together were a troublesome duo. Reborn is later on seen walking with Tsuna to Dino's hotel, later following Belphegor, who, upon their arrival, kidnapped Tsuna to Xanxus's office. As Reborn arrives, a man claiming to be the planner of the "Representative Battle of the Rainbow" arrives, introducing himself as Wonomichi and states that he would be explaining the battle, who does so. On the first day of the Representative Battle of the Rainbow, Reborn only goes up to Iemitsu and Colonnello after Tsuna is defeated by Iemitsu to form an alliance with them.
On the second day of the Representative Battle, Reborn takes Team Reborn, his team, to Team Yuni's mansion to hear some intel about Team Verde, who were immensely powerful on the first day of the battle. Night soon falls, and the battle begins, with Reborn and Yuni sitting in the mansion while their representatives fought. When Iemitsu terminates his and Team Reborn's alliance, Reborn is visibly angry. When Reborn attempts to stop Colonnello's Maximum Rifle shot along with Gamma and Tsuna, Reborn preparing to release his Arcobaleno Curse, Byakuran intervenes and takes the blow. When Tsuna is defeated by Iemitsu and the latter is about to hurl a boulder at the former, Reborn, in his un-cursed form, intervenes and easily heavily injures Iemitsu, while teaching Tsuna a lesson about his two largest flaws in battle, though Tsuna is unaware who the un-cursed Reborn is. Reborn leaves his un-cursed form and watches as Tsuna fights Iemitsu.
During the third day battle with Team Bermuda, Reborn noticed that Tsuna hesitated to fight full power out of fear that doing so would destroy the boss watch. Seeing that Tsuna slowly getting cornered, Reborn shouted at him to forget about the boss watch and fight like his life depends on it. Reborn then took out Tsuna's 0 test score, revealing that the only reason he joined the Representative Battle is to make him stronger, Finally convinced, Tsuna prepared to continue to fight with all of his strength even if the boss watch breaks. Tsuna understands Reborn and both he and Jaque start to fight at full power. After Tsuna defeated Jaque, Bermuda comes because he wants to invite Reborn onto the team. Reborn rejects the offer. Bermuda created a warp hole and sucked Reborn with Tsuna too because Tsuna wanted to save Reborn. They both arrive in a place with skeletons on the floor. Reborn said that he let himself get sucked because Reborn wanted to know what Bermuda meant about "the truth." Looking up, Reborn and Tsuna see a stone revealing the secrets of the Arcobaleno.
Bermuda and Jager appeared in front of them and started to explain that the Arcobaleno are human sacrifices that Checker Face has set up to protect the Pacifiers from generation to generation. Once the Arcobaleno's life span start to reach to the end due to the curse, Checker Face will choose seven people to become the next Arcobaleno through either contract job or Representative battle and removed the flames of the previous Arcobaleno from the pacifiers, leaving them either to die or becoming Vindice. To get his revenge on Checker Face, Bermuda offered Reborn once again to join him. Reborn questioned why he choose him out of all Arcobaleno and what will happen to the current Arcobaleno if Checker Face was killed. Bermuda explained that he likes crazy people like him and witnessing Tsuna's growth through his teaching is what made him realized how Reborn is different from the other Arcobaleno. He revealed that if Checker Face is defeated, the current Arcobaleno, the Vindice, and everything that involved with it will die as killing Chekcer Face means destroying the Arcobaleno system itself. Reborn didn't mind dying, but he disagreed if Lal and Yuni are getting involved with it. Tsuna, against the idea, declared that he won't let Bermuda win the Representative Battle. Hearing Tsuna's declaration, Reborn decided to follow Tsuna's will.
However, Reborn immediately changed his mind when Jager single-handedly overpowered Tsuna, seeing no possibility for Tsuna to win against him and told him that there's no need for Tsuna to die for them, the Arcobaleno since this is the Arcobaleno's problem alone. He told Tsuna that he can return the boss watch whenever he wants to. Once they got back, he immediately called the other Arcobaleno except Skull to a meeting and told them everything that Bermuda had told him. The meeting ended in a huge argument when Reborn considered joining Bermuda since he wanted to stop the Arcobaleno system even though it would be at the cost of his life while Colonnello doesn't want Lal to get into this and Mammon and Verde refused to die because of Bermuda's scheme. Yuni and Fon tried to mediate them, but Mammon used an illusion that accidentally hit Yuni. They finally stopped arguing, took Yuni to the hospital and parted ways without making up.
In the morning, Reborn finds Tsuna and Tsuna says that he has something to tell him. Tsuna brings Reborn to Namimori Shrine, deciding to skip school. When Reborn says that as a home tutor he wouldn't permit it, Tsuna angrily rants about everything that had happened ever since Reborn came into his life and tells Reborn that he's not qualifed to be a home tutor. After his outburst, Tsuna states that he won't let Reborn die.
After Talbot manages to find a peaceful solution to the Arcobaleno's problem, Reborn remains as Tsuna's tutor. After pretending to have changed his mind about making Tsuna the next Vongola boss, he leaves for a few days and then returns with a declaration that he now intends to make Tsuna "Neo Vongola Primo", which is essentially the same as "Vongola Decimo", just under a different title. Reborn is last seen joining Tsuna, Tsuna's Guardians and the girls for a celebration. He is the last character seen by the end of the manga.
Reborn is Timoteo's most trusted assassin. Timoteo is Vongola IX, and, as such, is the one who asked him to teach Tsuna how to succeed the Vongola Famiglia. Reborn thinks very highly of him and respects him. They often communicate with letters about Tsuna's progress and growth. The Ninth seems to reveal many secrets of the Vongola to Reborn since he knows that Reborn can be trusted with such information. When Xanxus stated that he had done something to the Ninth at Lightning Ring Battle, Reborn was already prepared with his gun. Also, when the Ninth was revealed to be inside Gola Mosca as part of Xanxus's scheme, Reborn stated that he had already lost his patience but wouldn't fight out of respect for the Ninth's will. He also often convinced Tsuna to think about the Ninth's feelings when Tsuna refused to take part in the Inheritance Ceremony.
Tsuna is Reborn's student. Reborn was sent to train him to make him a true successor of the Vongola Famiglia. He is quite hard and fierce to Tsuna, his Spartan methods of training, which make Tsuna more often than not, involved Tsuna getting shot, facing danger, and humiliation. This makes Tsuna become wary of him, and, due to Reborn's involvement with the Mafia, makes Tsuna try to avoid him. However, they later form a bond of friendship that allows them to work together after the many situations they have been through together and this bond is what makes a drastic improvement in Tsuna's ability and character to lead the Vongola, something that Tsuna recognizes, though Reborn still largely remains a teaching figure.Reborn has also shown concern for Tsuna's well-being, as shown when he was frustrated as he watch Tsuna being beaten up by Daemon and wanted to help him if only the Vindice didn't interfere. Colonnello has said that Reborn is like another father for Tsuna, as he is always there for Tsuna when he needs him and will do anything if it will help Tsuna grow. The extent of Tsuna's and Reborn's bond is shown to be very deep, proven when Tsuna shouts at Reborn when the latter about to give up the Representative Battle, which finally bring up Reborn's desire to live longer in order to watch his student's growth.
Dino was Reborn's student before Tsuna. Reborn was sent to train him to make him the Boss of Chiavarone Famiglia. Similar to Tsuna, Dino was treated fiercely by Reborn with Reborn's Spartan methods of training that made the young Dino become wary of him, and until now, still does. Reborn often likes to tease and make fun of Dino, referring him as No-Good student of his along with Tsuna. Despite Reborn's treatments, Dino has come to respect Reborn and is grateful to him since it is thanks to Reborn's training that Dino has become a great and dependable Boss for his Famiglia. Dino and Reborn care for each other but are not quite as close as Tsuna and Reborn are.
Reborn briefly tutored Yamamoto during the Future Arc. Although Yamamoto sees Reborn as a child, he respects the latter's power and skills. Reborn also favors Yamamoto and even revealed an Arcobaleno secret to him after Yamamoto was able to land a hit on Reborn's hat in combat.
Reborn forms a special relationship with Luce, Aria, and Yuni, who all share the same blood and destiny. Before becoming an Arcobaleno, Reborn seems to be close to Luce and cares for her. Luce was also the one who commented that Reborn's sideburns were his most attractive feature. Reborn is mostly seen with Luce and they were shown to have talked about personal or Famiglia problems. After Luce's disappearance, Reborn was also the first person who realized the resemblance of Aria with Luce and apologized to her for forcing her to carry the Arcobaleno curse. Aria also sees him as a good friend possibly because of his relationship with her mother. In the Future, the first time Reborn met Yuni, he immediately recognized her, just like when he met Aria. Yuni also immediately called Reborn "Uncle." He can act very protective of Yuni because she is the Boss of the Arcobaleno. He is also the only one who understood her feelings and her destiny as the Sky Arcobaleno, just like her mother and grandmother.
Colonnello, Lal, and Fon are Reborn's old friends. Colonnello claims to be his great rival but they actually have a lot in common and share some of the same qualities and traits, like having a sharp tongue and sleeping out of the blue. They also often punish Skull when he had done something stupid.
Lal acknowledges Reborn's strength and even admitted that he was the strongest Arcobaleno, though she is often irritated by him because he knows what she was thinking and what action she will take, which ends up in argument. Reborn sometimes like to tease Lal since she doesn't have a sense of humor.
Reborn rarely interacts with Fon since Fon lives in China, but they are on good terms. Reborn acknowledges Fon as a high-skilled martial artist and both of them also give some suggestions to each other whenever needed.
Skull, on the other hand, is only seen as an errand boy or a lackey, which annoys Skull because he feels that Reborn never sees him as an equal, but also found that he's afraid of Reborn when he starts to punish him. Skull often tries, to no avail, to prove that he is superior that always resulted him being punished by Reborn.
Reborn and Mammon don't seem to be on good nor bad terms; however, Mammon thinks of Reborn as a shameless and foolish person but, at the same time, is also aware of his strength.
Out of all Arcobaleno, Verde is the one that Reborn doesn't get along the most. Reborn never considered Verde as a comrade and found it hard to trust him due to Verde's obsession with his research and the fact that he will do anything to accomplish it. Verde only thinks of his research and didn't care when he broke the Arcobaleno Pact, and he sees Reborn and the others as merely a subject of his research. He commented that he found it unpleasant to be with the other Arcobaleno and Vongola. Their mutual dislike towards one another is furthered shown when Verde joined the Representative Battle simply because he wanted to defeat Reborn.
