Keigo Asano

Keigo is a student at the Karakura High School, in the same classroom as Ichigo Kurosaki. He is an extremely hyperactive character and often use overly-dramatic movements and words to act out his feelings. In other respects, he is the stereotypical Japanese teenager. The Asano family consists of Keigo's mother, father, his sister Mizuho, and Keigo himself.

Keigo is used mainly for comical effect. He is good friends with fellow student Mizuiro Kōjima. Keigo appears to be a shallow character at first glance, with a passion for slacking off. Indeed, he takes great pride in not making it to the honors roster (higher than the 50th ranking) and labels those who do so "traitors" (including Ichigo and Chad). However, Mizuiro states that Keigo is much smarter than his bad grades show. In a recent omake, he imagined Ikkaku to be a spy with a license to kill or a shogun's bodyguard who cuts down evil-doers. Mizuiro suggested that Ikkaku would be his older brother, as his sister Mizuho likes Ikkaku, much to Keigo's chagrin.

Keigo, like many of Ichigo's friends, is spiritually aware as a result of constant contact with Ichigo. While he can see spirits and other such supernatural phenomena, he has not manifested any unique abilities, much like Tatsuki Arisawa. He only becomes aware of the fact after seeing Ikkaku Madarame in battle, having dismissed his previous sightings as shootings for a TV show.

During the arrancar invasion, Ikkaku and a few others crash at his place due to Ikkaku saving him and a touch of intimidation.
