Yumichika Ayasegawa

is the 5th Seat of the 11th Division, his captain is Kenpachi Zaraki.

Character Outline
Yumichika is the narcissist friend of Ikkaku Madarame. Yumichika is a powerful combatant and wanted to become the 3rd Seat, since he thought the kanji for the number three was the most beautiful, though Ikkaku took it, so Yumichika took 5th Seat, as he thought that the kanji for 5 resembled 3. He has colorful feathers on his eyelashes and eyebrow, and shiny skin and hair, giving him a rather womanly appearance in the early manga. Yumichika judges everyone and everything by beauty, and is also incredibly vain. However, he is at times shown to be caring and helpful to others. He along with Renji Abarai are the only two people who have seen Ikkaku's Bankai although, Keigo Asano also might have seen it.

History
Yumichika knew Ikkaku from a long time ago, before Zaraki was a captain. During their past the two went throughout the Rukongai together looking for fights, and one day Ikkaku lost to Kenpachi Zaraki. After a speech given to them by him about living to kill the one who failed to kill them, and later after hearing news of Kenpachi becoming a captain, the two joined the 11th Division to serve under him. They proved themselves to Zaraki and became seated officers.

Synopsis
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 manages to defeat Yumichika with an explosive. He later fights 9th Division lieutenant Shūhei Hisagi when he tries to stop Kenpachi from helping Ichigo's friends, and wins by releasing his zanpakutō. Yumichika is also sent to Karakura Town to fight off the Bount, and commonly helps Ichigo and friends fight off the Bount, and also heads 11th Division matters with Ikkaku while Kenpachi is unable to. Yumichika is later assigned to Tōshirō Hitsugaya's team to fight off the arrancar, and prevents Keigo Asano from interfering with Ikkaku's battle with Edorad Leones. He later loses to Luppi in the third invasion of the arrancar.

Zanpakutō
Fuji Kujaku (Wisteria Peacock):


 * Shikai: The shikai command for Fuji Kujaku is "bloom" (sake, "bloom for me" in the English adaptations). In its shikai, Fuji Kujaku 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 Fuji Kujaku to split into four identical blades. Although Yumichika doesn't admit it to his 11th Division comrades for fear of being hated, since 11th Division zanpakutō are generally used for direct attack, he has a kidō-type sword.


 * Shikai Special Ability: By using the command sakikurue (tearing deviate), Fuji Kujaku flares up and takes the appearance of many peacock feathers, after which it drains the opponent's spiritual power, allowing him to beat even lieutenant-level fighters with apparent ease. Powerful as it is, Yumichika only makes use of his zanpakutō's kido properties when no other member of the 11th Division is around, lest they witness the true nature of his zanpakutō.

It is also assumed he's trying to learn his bankai, though Fuji Kujaku is just as narcissistic as Yumichika himself, leading Yumichika to comically yell at his sword while trying to break it against a boulder.
