Byakuran is the former Boss of the Gesso Famiglia and the current leader of the Millefiore Famiglia. Due to the actions committed by his future-self, he is considered the main antagonist of the Future Arc. In the present, he is chosen as Yuni's representative in the Representative Battle of the Rainbow.
Byakuran has spiky white hair and light purple eyes. His distinguishing feature is a purple tattoo under his left eye. In his first appearance, he wears the standard White Spell uniform with a Mare Ring symbol on the side of his shirt and has silver shoulder pads with the Millefiore insignia like the other members. In the Choice Arc, Byakuran wears a white shirt under a black jacket with the Millefiore insignia. Kikyo and Zakuro also wear the same outfit. In the final battle, Byakuran wears a white outfit and a purple jacket; he also has scars on his back, where he grows his black and white wings. In the present, he dons more casual clothing, wearing a hooded vest, a long-sleeved shirt, still wearing his choker, a loose belt, and ripped jeans.
During his first appearance in the Future Arc, he is shown to have a cheerful disposition around his subordinates, especially toward Shoichi Irie, even though he knew of the latter's betrayal. He even threatens one of his Funeral Wreaths, Bluebell, after she suggests he kill Yuni for her acting arbitrarily. Otherwise, this is only if they hold his interest; he hides his ruthlessness and cruelty behind a good-natured facade. Once he "gets bored" of someone, he won't hesitate to have them killed. He will do anything to achieve his goal, not caring if it would mean sacrificing innocent people or destroying the world, even referring to them as his toys.
In the present time, however, after his future-self was defeated by Tsuna, Byakuran seems to have had a change of heart even though he still retains his carefree and easy-going personality, which Gamma finds annoying most of the time. His change was clearly proven when he protected Tsuna from Collonnelo's Maximum Rifle simply for the sake of Yuni, who has been kind to him from the bottom of her heart, stating that he would protect her.
Initially, his aim was to obtain the "Ultimate Power" (Tri-ni-set) by gathering the Vongola Rings, Mare Rings, and Arcobaleno Pacifiers together in one place; he has a portrait with a slot for each item. To achieve his goals, Byakuran has ordered the complete extermination of the Vongola Famiglia, even targeting their friends and allies. He had a special radiation released into the atmosphere in order to kill all Arcobaleno members which was called Non Tri-ni-Set. Before the appearances of young Tsuna and his friends in the future, Byakuran had been researching them, as well as time travel, in order to get ahold of the Vongola Rings, which had been destroyed in his time.
According to Shoichi, Byakuran's power can only be used during certain circumstances and that their era's unique events are what created his power. He has the ability to communicate with every other Byakuran that is in a different parallel universe, giving him the knowledge and experience he gained from countless worlds, which is similar to Mukuro, who has the collective experience from living in each of the six realms of existence.
Revealed by Shoichi after the Choice game, Byakuran met Shoichi's younger self many times after Shoichi came into possession of shells for the 10 Year Bazooka. However, his ability to see into parallel worlds was awakened because the same Shoichi from the past met Byakuran of two different futures. With this ability, Byakuran was able to use knowledge from different parallel worlds to become ruler of each of them. Though such immediate progress was deemed impossible by Reborn, Shoichi reveals that Byakuran sent a device containing information of the parallel worlds to the younger Byakuran through Shoichi. This effectively allowed Byakuran a ten-year head start in his progress to rule the world.
Byakuran is the leader of the Millefiore Famiglia, which came about after a merger between his old Gesso Famiglia and Yuni's Giglio Nero Famiglia. He had a fight with Mukuro Rokudo, who was spying on the Millefiore Famiglia under the guise of Leonardo Lippi, whose true identity was soon known by Byakuran after he joined.
Merone Base Invasion
Byakuran appears in hologram form at the end of the Merone Base Invasion to announce that he knew Shoichi would betray him, and that he had Real Six Funeral Wreaths waiting to fight the Vongola Famiglia. They arrange for a game called "Choice" to be played in a few days' time. The Vongola Famiglia agree to it, and Byakuran's hologram disappears.
Byakuran is first seen going to get five of his Real Funeral Wreaths and later appears before the Vongola Famiglia in the form of a giant storm cloud. He watches as Tsuna and his Guardians generate twice the amount of Fiamma Volts necessary to transport them, the rest of the Family, and their base to the Lightning Field that Tsuna goes on to select.
He explains the rules of Choice and he and Tsuna use the Gyro Roulette to select the participants. For his Family, Kikyo, Saru, Torikabuto, and Daisy were chosen to participate, the match of which ended in the favor of the Millefiore. However, when he comes to claim his prize, Shoichi reveals that when the two were creating Choice, if he lost their next match, he would get one request which he uses now: he requests a rematch. Byakuran refuses, claiming he never made such a promise. However, Yuni suddenly appears telling Byakuran that as the co-leader of the Millefiore Famiglia she should have a say in the matter. This prompts a serious look from Byakuran for the first time since his appearance.
Byakuran comments that Yuni is looking better, resulting in Shoichi revealing that Byakuran had drugged her and made her into a shell of her former self in order to gain control over Black Spell, essentially turning her into a figurehead. Yuni reveals that she countered this by putting her heart someplace "far away". She then goes on to say she has the same power as Byakuran. After reiterating her reinforcement of the rematch, Byakuran shoots it down, claiming that she was only the second-in-command, at which point she withdraws her Famiglia from the Millefiore and asks for protection from the Vongola.
Upon learning about Yuni taking the Pacifiers and witnessing their resurrection, he tries to force her to go back to his side but was stopped by Reborn. With a passive approach, Byakuran proposes to Yuni that the Vongola Rings stay with the Vongola Famiglia in exchange for her return to the Millefiore side together with the Arcobaleno Pacifiers. But Yuni refuses the proposal saying that she knows why Byakuran wants her back. In response, Byakuran threatens Yuni that harm will befall the members of the Black Spell if she continues with the betrayal but Yuni stands firm.
As a result, he sends Torikabuto, Zakuro, and Kikyo to attack Vongola members but they were trapped by Hibari's Box Weapon. Thus, Byakuran himself pursues Yuni who was escaping together with the Vongola Famiglia and states that he won't be stopped. When Bluebell asks Byakuran why he didn't kill Yuni, he threatened to kill her if she ever mentioned it again. Byakuran and five of his Six Wreaths then search for Tsuna's Family.
Byakuran came back from his search of the parallel worlds and stated that he found where Kawahira was and where he was hiding Tsuna and the others. After the final battle between the Real Six Funeral Wreaths and the Vongola begins, Byakuran sent Ghost to the battlefield, uncaring that Ghost's ability to absorb Flames resulted in the death of 2 of his Funeral Wreaths. After Ghost is defeated by Tsuna, Byakuran himself shows up and reveals that all of the Flames absorbed by Ghost went to him.Tsuna's seemingly successful attacks on Byakuran are rendered completely ineffective against Byakuran's attacks. Additionally, the unity of the Sky elements of the Tri-Ni-Set coming together isolates the battle from everyone but the two bosses. In response to Byakuran's taunts of his pitiful life, Tsuna says he has no regrets and Vongola Primo appears from his Vongola Ring, releasing the limiters of the Vongola Rings and granting them maximum output, with this Tsuna beats up Byakuran and rips off his wings. Byakuran gets up and states that in all the parallel worlds, this parallel world's Tsuna is the only one to make him spit out blood, prompting him to use his full power. Byakuran and Tsuna soon engage into a fight once again, but Byakuran changes his motive into getting back Yuni rather than toying around with Tsuna after seeing Yuni was serious to sacrifice herself for the revival of the Arcobaleno.
Byakuran failed to retrieve Yuni as she and Gamma sacrificed themselves to revive the Arcobaleno. Both attack each other at full strength, ending in Byakuran's defeat. Immediately prior to his defeat, Byakuran recalls the time when the Cervello had chosen him to be the holder of the Sky Mare Ring.
After Lambo's battle with Rauji Ooyama, Byakuran appears with his Wings extended in the hospital room where Yamamoto was lying unconscious; Yamamoto later states that Byakuran healed him, due to the fact that he looked out the window and saw him. It was also said that Byakuran looked 'refreshing'.
The present Byakuran reappears with the Six Funeral Wreaths (except Ghost) after the Sky Pacifier began expelling flames in front of Gamma, Nosaru, and Tazaru. Despite the outbursts of Gamma and the other members of the Giglio Nero Famiglia, Byakuran remains calm and announces that he and the Wreaths would be fighting in the tournament as the representatives of Yuni along with Gamma, Tazaru, and Nosaru. Yuni then appears from the forest, clutching the Sky Pacifier as it falls towards her.
Yuni then greets everybody, also thanking Byakuran for fighting for her. Both he and Yuni anticipate meeting Reborn and Tsuna, Byakuran also anticipating meeting Shoichi and noting that Tsuna was interesting, having defeated his future self. Afterwards, he is seen agreeing with Yuni that they had to plan their battle carefully after being informed of the Representative Battle of the Rainbow's rules by Wonomichi. He also lightly smiles when Gamma shouts in frustration, wondering why Yuni asked Byakuran as well as himself, as Gamma thought Yuni only needed him. The next day, Byakuran visits Tsuna's house slightly later than the CEDEF and offered to Tsuna that they form an alliance in the upcoming battle royale of the Representative Battle of the Rainbow. He is eliminated on the second day of battle when he protects Tsuna and the rest of Team Reborn from Colonnello's Maximum Rifle. Tsuna visits Byakuran after the third day of battle and asks for his help to fight together with along with the other teams. During the fourth day of the battle, he, along with Dino, Mukuro, Squalo, and Xanxus become elite members of the Allied Team and participate in the battle with the remaining wrist watches to fight Jager, preventing the latter to help his two teammates. After the battle, Mammon soon charged him 10,000,000 yen an hour for replacing his organs with illusions.
In the future, Byakuran sealed Yuni's soul to collect the Arcobaleno Pacifiers and awaken the Trinisette. Upon Tsuna's intervention and Yuni coming back to her senses, Byakuran expressed nothing but the fact that Yuni was his last piece upon awakening the Trinisette, and anger when 'his toy' died. However in the present during the events of the Rainbow arc, their relationship improved greatly. He became Yuni's team boss representative. When Tsuna questioned him about his motive, Byakuran said that similar to Tsuna in the future, he felt the same regarding Yuni - he wanted to do things properly and give it his best for the sake of that child.
In the future, Byakuran doesn't really care about his comrades. No remorse was given when they had died despite being their saviour who had helped each of them when they were at their lowest in life. To Byakuran, he hadn't done it out of care, but out of the fact that they had been useful to him and his plans. In the present, his relationship with the Six Funeral Wreaths has improved as it appears that he cares for each of the members compared to his future counterpart.
Byakuran was Tsuna's enemy in the Future Arc and taunted him about his misfortune, while also expressing satisfaction that he had finally found a worthy opponent. Tsuna's older self concocted an elaborate scheme to defeat Byakuran, which succeeded when Tsuna killed him. At present, however, their relationship has improved to the extent that Byakuran defended Tsuna from an attack launched by Colonello. In his first appearance after returning from the alternate future, Byakuran briefly visited the Sawada residence and was eager to see Tsuna's room. According to Yuni, Byakuran and Tsuna are similar in a way neither of them understands.
Byakuran had met Shoichi when they had still been in university and had befriended each other along the way. It was also because of their friendship that they decided to create the game called choice, which is later used as a battleground between the Millefiore and Vongola, to pass the time. In the future, when Shoichi had turned out to be on the Vongola's side, Byakuran had revealed that he had known all along about Shoichi's true intentions to defeat him. Shoichi had been saddened at Byakuran's defeat and death, but he had held strong on his belief that Tsuna had to defeat Byakuran for the greater good. After Tsuna had killed Byakuran and everyone returning to the present, Shoichi seems to have renewed his friendship with Byakuran.
Weapons and Abilities
Due to Shoichi traveling to the future and meeting two versions of Byakuran, Byakuran is mentally connected to every other Byakuran living in the separate parallel universes. This knowledge is utilized as a battle advantage: the Real Six Funeral Wreaths know about the techniques of the enemies he fought in these worlds. However, Byakuran becomes greatly weakened and needs a day to recover after using this ability. It is also mentioned by Yuni that Byakuran's powers are growing weaker over time.
- Sky Mare Ring: Granted to Byakuran due to his ability to see into parallel worlds. Byakuran is capable of firing bolts of energy from the Ring and has several White Dragons that appear to grow from it, to aid him when fighting.
- Ghost: Ghost has the ability to drain the Dying Will Flames of all those who are close by; however, he is also a version of Byakuran brought from another parallel world. As such, Byakuran can steal any Dying Will Flames Ghost absorbs and make them his own, greatly increasing his speed, stamina, and attack power.
- White Dragon: (白龍, Shiroryu) The White Dragon is Byakuran's Box Weapon. It was made with the highly advanced technology of the Millefiore Famiglia and is exclusively for him.
- Black Dragon: The Black Dragon is a Box Animal used by Byakuran. Unlike the White Dragon, the Black Dragon is able to split and multiply, making it harder for the enemy to avoid attacks.
- Wings: Byakuran's scars on his back have been revealed to be space for him to grow a set of White Wings made of Dying Will Flames (however, these are possibly only for appearance's sake, as he already has Flame Boots). They also seem to be a result of looking into parallel worlds. Once torn off, they grow back as a black pair capable of morphing into claws. Byakuran's final attack can be compared to Tsuna's X-Burner, only with black Flames. However, Byakuran grows roots from his back that shoot out of his legs to support him during this attack instead of using a Flame "cushion."
- White Applause: (白拍手, Shirohakushu) Byakuran can negate any attack by clapping his hands. This technique requires a certain degree of power to match the opponent's attack, however, as Byakuran's palms were injured when he tried to negate Tsuna's more powerful Burning Axel.
- White Finger: (白指, Shiroyubi) Byakuran simply focuses Sky Flames from his ring and launches a powerful shockwave type attack that blasts his opponent with tremendous force from his finger.
- Transparent Giant Hand: Byakuran is able to create a giant hand which is linked to his own, to capture the enemy from a distance.
- Black Flame Attack: Byakuran grows roots from his back that shoot out from his legs and plant themselves in the ground in order to stabilize him. Next, Byakuran concentrates Black Flames from his hand which rotates at an extremely high speed and then releases them as a blast.
- Healing: Due to the vast knowledge he gained from the Parallel Worlds, Byakuran knows extensive healing techniques. His skill in this area is so great that he could completely heal a person whose condition is critical enough for regular doctors to give up hope.
- Byakuran participated in an extra manga skit called "What if Reborn!" as a grocery store worker. However, all of the vegetables he sells turn out to be marshmallows.
- Byakuran's Future self is the first person that Tsuna has ever killed.
- The Real Six Funeral Wreaths are all named after flowers. Byakuran was named after the white orchid.
- His shorthand used in fandom is 100, because the first kanji of his name can be read as 'Byaku' which is used for '100' as well as means 'white'.
- He has a sweet tooth, as he is often seen eating various confections throughout the manga and anime, namely marshmallows. One of his new favorite candies is Namimori's style custard cream puffs, similar to Kyoko's favorite.
- When the people from the present that went to future returned to the past, the present Byakuran is seen without his tattoo; however, in Inheritance Ceremony Arc and Curse of the Rainbow Arc, Byakuran has the tattoo.
- In the most recent poll, Byakuran ranked 7th in strength.
- During Mr Rebokku's Ciao Ciao Interview, Byakuran stated that his favorite word was 'World Peace'.
- Byakuran has two character songs: Perfect World and PARADE.
