Overview Yumichika Ayasegawa
is the 5th Seated officer in the 11th Division of the Gotei 13, his captain is Kenpachi Zaraki.
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 colorful feathers on his right eyelashes and eyebrow. He has shiny skin, Purple and jaw-length black 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.
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.
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.
Ruri'iro Kujaku (aka Azure Peacock), "Nickname" Fuji Kujaku (aka Wisteria Peacock). 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 Kujaku is an odd sword, as it has a favorite color. "Azure" is its favorite while "Wisteria" is its 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. The spirit of Ruri'iro Kujaku seems to be as vain as his owner, as Yumichika is shown visibly getting angry with him for thinking of himself as beautiful, saying that he is full of himself. He even goes as far as to call his Zanpakutō annoying and tries to break the blade after performing Jinzen.
