Yumichika Ayasegawa

Yumichika is the narcissist friend of Ikkaku Madarame. 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. Yumichika wanted to become the 3rd Seat, since he thought three was the most beautiful kanji, though Ikkaku took it, so Yumichika took 5th Seat, thinking that 5 looks almost like a 3.

It is not entirely clear if Ikkaku maintains the seat due to if he is superior to Yumichika, or if Yumichika allows him to have because of their friendship.

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.
