Yumichika Ayasegawa

is the 5th Seated officer in the 11th Division of the Gotei 13, his captain is Kenpachi Zaraki.

Appearance
Yumichika wears the standard Shinigami Shihakushō uniform with some customizations. An orange piece of clothing sits on top of his uniform around the neck, which covers most of his chest that would otherwise be exposed by his uniform. This is connected to an orange sleeve on his right arm under the much looser fitting sleeve of the uniform. Yumichika has colourful feathers on his right eyelashes and eyebrow. He has shiny skin and jaw-length hair, which, in conjunction with the feathers, gives him a somewhat feminine appearance. Before he joined the Gotei 13, he wore a simple kimono with a flowery pattern on it, did not wear any feathers on his eyes, and his hair was down his back and tied in a loose ponytail with shoulder length pieces framing his face.

Personality
Yumichika is a narcissist who judges almost everyone and everything by beauty. He is also incredibly vain. Yumichika is a powerful combatant and wanted to become the third Seat of his Division, as he thought the kanji for the number three was the most beautiful. However, Ikkaku Madarame took it, so Yumichika took the fifth Seat, as he thought that the kanji for five resembled three. However, he is at times shown to be caring and helpful to others. He is extremely loyal to his friend Ikkaku, even going as far as to abandon his post at a pillar in the fake Karakura Town to try and save Ikkaku from being killed and threatening his allies who try to stop him. He cares deeply about what Ikkaku and Kenpachi think and hides the true nature of his Zanpakutō from them for fear of being hated.

History
Yumichika was a friend of Ikkaku Madarame from a long time ago, before Kenpachi Zaraki became a captain in the Gotei 13. During their past, the two went throughout the Rukongai together looking for fights, until the day where Ikkaku challenged Kenpachi to a fight and lost to him.

After a speech given to them by Kenpachi about surviving a battle and living to kill the one who failed to kill them, Yumichika brought the news to the still recovering Ikkaku. He had heard of Kenpachi becoming a captain and the two decided to join the 11th Division to serve under him. Both of them would prove themselves to Kenpachi and eventually became seated officers, Yumichika choosing the 5th seat as he found the number four to be an unattractive number and Ikkaku had already taken the third.

Soul Society arc
Yumichika, alongside Ikkaku, finds Ichigo Kurosaki and Ganju Shiba shortly after they arrive in Seireitei, and Yumichika fights off Ganju. Ganju spends most of the time running away and playing unsuccessful tricks, though he finally manages to defeat Yumichika with a type of blast bomb aimed right at his face. It is later the revealed that Yumichika easily recovered and that the bomb merely ruined his hair.

When Makizō Aramaki brings Orihime Inoue to the 11th Division, Kenpachi decides to help her because it means he will have a chance at a rematch with Ichigo. He brings along Yumichika, Ikkaku and Yachiru to break out Orihime captured allies. When busting into the prison Yumichika is noticed by Ganju, but Yumichika feigns to have forgotten him saying that he does not remember ugly people. When the captains and lieutenants of the 9th and 7th Division tries to stop the group, Yumichika winds up fighting with 9th Division lieutenant Shūhei Hisagi, when they try to stop Zaraki's group. After initially struggling, Yumichika wins by releasing his Zanpakutō's true Shikai form.

Bount arc (anime only)
Note: Events occurring in this arc are only in the anime and do not constitute canon material.

When the Bounts begin attacking living humans, Tōshirō Hitsugaya puts together a team of Shinigami consisting of Yumichika, Shūhei Hisagi, Rangiku Matsumoto, and Izuru Kira. Yumichika questions Hitsugaya as to why he was elected for the assignment. Hitsugaya explains that Kenpachi told him that Yumichika was the only one "with nothing better to do". Initially, Yumichika is the only one working on his own when the team arrives in Karakura Town, while the other Shinigami sent are assisting Ichigo and his friends who are dealing with the Bounts. Yumichika eventually manages to find the Bounts' main hideout, but decides to wait for the rest of his team.

When the rest of the team Hitsugaya organized arrives, Yumichika decides to go ahead on his own, but he (along with the rest of the group) is defeated by Ugaki's Doll. He is later found by Ichigo and Renji Abarai, who arrive later. They decide to carry Yumichika along, but they are all confronted by by Ugaki and his Doll in its full form. Renji decides to fight on his own, insisting that both Ichigo and Yumichika stay out of the battle. Ichigo shows numerous protests even during the battle, but Yumichika reveals to him that Renji used to belong to the 11th Division; and most members of the 11th Division fight to the death on their own, Renji being no exception (even after he was transferred). After Renji defeats the Doll, he can no longer continue. Yumichika urges Ichigo to continue on, telling him that he would look after Renji, so he wouldn't have to worry about him.

Yumichika also heads 11th Division matters along with Ikkaku, while Kenpachi and Yachiru are unable to.

Arrancar arc
Yumichika is later assigned to Tōshirō Hitsugaya's team to fight off the Arrancar. During the attack led by Grimmjow, he prevents Keigo Asano from interfering with Ikkaku's battle with Edrad Liones. During the third invasion led by Luppi, Yumichika takes part in the battle against him, but loses.

Fake Karakura Town arc
When Aizen and the top three Espada invade the fake Karakura Town, he along with Ikkaku, Shūhei and Izuru Kira, are left to protect the pillars that hold the real Karakura Town in Soul Society. Barragan Luisenbarn sends his Fracción to do battle at each point, with Yumichika getting paired with Charlotte Cuuhlhourne. Though initially their somewhat similar personalities cause an argument in a comedic fashion, the fight quickly turns serious, with Yumichika getting overpowered by Cuuhlhourne's attacks. He provokes the Arrancar to release his sword by slicing part of his hair after getting called his rival, greatly annoying himself. After Cuuhlhourne uses his ability, Rosa Blanca, to conceal the fighters completely, Yumichika is told that he will die a horrible death because no one can see them. Realizing that no one can see them, Yumichika activates his sword's true form, Ruri'iro Kujaku, and drains his Spiritual Energy.

As Charlotte asks if that form was the second stage of a Zanpakutō, a Bankai, Yumichika reveals his reasons to keep the true self of his Zanpakutō a secret from everyone else, believing it would have him kicked out of the 11th Division. He then takes a small bite of one of the petals to heal himself.

He is later surprised, along with the other Shinigami present, that Ikkaku lost his fight and becomes erratic and proceeds to go to his friend's aid. Hisagi tries to calm him, but Yumichika does not listen to him. This causes Izuru to knock him out with an anesthetic agent, stating that his manners are not appropriate when addressing his superiors and that he needs to calm himself.

Zanpakutō Unknown Tales arc (anime only)
Note: Events occurring in this arc are only in the anime and do not constitute canon material.

Yumichika, along with all other Shinigami who had learned their Zanpakutō's name, is called to Sōkyoku Hill under the belief that Captain Yamamoto called them. This is proven to be a trap set up by a rogue Zanpakutō spirit named Muramasa, who called them and had captured and sealed Yamamoto. To make matters worse, Muramasa somehow "frees" all the Zanpakutō spirits from their spiritual bond with their Shinigami partners.

Yumichika is not seen again until he arrives with other Shinigami to the 6th Division Barracks to surround some of the rogue Zanpakutō spirits and Captain Byakuya Kuchiki. He then lures away his Zanpakutō spirit, Ruri'iro Kujaku, to a secluded place so that no one sees the true power of Ruri'iro Kujaku. He and Ruri'iro Kujaku talk, with Ruri'iro Kujaku complementing Yumichika on his looks. This annoys Yumichika, who proceeds to provoke Ruri'iro Kujaku by calling him Fuji Kujaku. They prepare to fight each other with Ruri'iro Kujaku swearing to kill Yumichika for calling him Fuji Kujaku.

Yumichika is later seen in a bad condition, a triumphant Ruri'iro Kujaku smirking nearby. After remarking that he is unafraid to use his true power, the Zanpakutō prepares to unleash his Shikai. Yumichika panics, still more afraid to be kicked out of the 11th squad than to die; even after he is caught by the Ruri'iro Kujaku's Shikai, he stubbornly calls his Zanpakutō Fuji Kujaku. As Ruri'iro Kujaku's power continues to drain away Yumichika's energy, he mocks Yumichika by calling him a coward, saying he claims to value his self-perceived vision of beauty and expresses it to all, yet he hides his true power from the others in fear of being ridiculed.

After using some improvised Kidō to escape, Yumichika tricks Ruri'iro Kujaku by playing on his ego to use his powers again, finding an opening to counter and win. Before striking down his Zanpakutō, Yumichika explains that despite his reluctance to show his true powers to others, he chooses to do this not out of fear of ridicule, but because he has true pride as a member of the 11th division. After winning the fight, Yumichika faints from having lost so much energy from Ruri'iro Kujaku's power. He is later found by the 4th division and treated.

After recovering, Yumichika goes to the living world with several Shinigami, ready to face Muramasa.

Zanpakutō
Ruri'iro Kujaku redirects here. For the manifested spirit that appears in the Zanpakutō Unknown Tales arc see Ruri'iro Kujaku (spirit).

, "Nickname". It has the form of an average katana with a bronze cross guard shaped like a German cross and a purple handle.

Ruri'iro Kujaku is his Zanpakutō's true name. Ruri'iro Kuajaku is an odd sword it has a favorite color. "Azure" is it's favorite while "Wisteria" is it's least favorite. FuJi Kujaku is a Nickname that Yumichika gave it. Ruri'iro Kujaku really hates that name, so when Yumichika calls it that his Zanpakutō sulks and doesn't reach full power. It is only when he calls it by its true name, that its potential is achieved. Although Yumichika does not admit it to his 11th Division comrades for fear of being hated, especially by Ikkaku, since 11th Division Zanpakutō are generally used for direct attack, he has a Kidō-type Zanpakutō.


 * Shikai:
 * Fuji Kujaku: The Shikai command for Fuji Kujaku is . Yumichika runs his hand along the length of the blade as it glows a white light and transforms. As Fuji Kujaku, it takes the form of a sickle-shaped blade, or falx, distinguished from the khopesh by the cutting edge being located on the inside. A hinge at the hilt allows it to split into four identical blades. The guard still takes the form of bronze cross and it also retains the purple handle.


 * Ruri'iro Kujaku: When Yumichika says the command release . Ruri'iro Kujaku's blades flare up and transform into a number of glowing peacock feather-like vines. The guard still takes the form of bronze cross and it also retains the purple handle.


 * Shikai Special Ability: These vines move to grapple and ensnare an opponent. Once the opponent is sufficiently subdued the vines begin to grow energy buds that are being filled with the opponent's Reiatsu. The flowers actually use it as a form of power source, siphoning the Reiatsu the opponent emits in order to fuel their growth. When the flowers bloom the collected Reiatsu is turned against the opponent, either seriously incapacitating them or killing them in the process. By chewing on the petals of the bloomed flowers one's wounds are healed and their Reiatsu is revitalized. (It should be noted that the command Split and Deviate is the true release command for Yumichika's Zanpakutō). When the effect is over the vines release the target and shrivel up. The vines then recede back into the hilt and the sealed blade is reconstituted.


 * Bankai: Not Yet Achieved

Quotes

 * (To Ganju Shiba) "It's time. I'll let you choose. Would you rather I kill you, or would you like to jump into that pit and die? Please look this way and show me your expression. I want to see just how ugly you can get. Doesn't matter which one you choose, you'll still die either way. I can't take it when people are faced with a life and death situation and they don't know what to do."


 * (To Ganju Shiba) "This is inevitable I guess. Ugly people are always jealous of pretty people. It's only natural."


 * (To Ganju Shiba) "If you were a little bit less ugly, I might have spared your life."


 * (To Ganju Shiba) "Be sure not to make the same mistake again when you reincarnate. Ugly things are completely worthless. Since you're already ugly, I'll give you a clean, pretty death to compensate."


 * (To Shūhei Hisagi) "I haven't lost yet! I'm sorry, but you have to be dead for it to be considered a loss in the Eleventh Division."


 * (To Charlotte Cuuhlhourne) "I refuse to look upon something so hideous."


 * (To Charlotte Cuuhlhourne) "Rival, huh? You talk like you've acknowledged my strength, but I'm not interested in flattery from someone with such a messed-up hairstyle as that."


 * (To Charlotte Cuuhlhourne) "I'm a member of the Eleventh Division - the Gotei 13's specialized combat division. It's full of idiots obsessed with putting their lives on the line. Thanks to the style of our Division, there's always been a kind of unwritten rule that all our Zanpakutō have to be direct-combat types. Just having a Kidō-type Zanpakutō is enough to get a guy labelled a coward. I don't want any of my fellows in the Eleventh Division to see this Zanpakutō's ability. Especially not Ikkaku or my captain. That's why I had to thank you when you concealed us within the briar. If you had not used that technique, then no matter what happened in this battle, I would never have released my Zanpakutō. Even if I were to lose and die at your hands."
