Asano, Keigo

浅野啓吾

Keigo is generally a goofy and extremely hyperactive character, frequently employing overly dramatic movements and words to express his feelings. In other ways, he fits the stereotype of a Japanese teenager: he enjoys watching fireworks, playing role-playing games, attending beach parties, and so on. Initially serving as little more than a source of comic relief, Keigo becomes a more prominent character later in the series. The Asano family comprises Keigo's mother, father, his sister Mizuho, and Keigo himself. Like Tatsuki Arisawa, he is unusual in that he lives with both parents, unlike many other recurring characters in the series.
A good-natured teenager, Keigo is used primarily for comical effect, typically in situations involving failed attempts to woo girls and interactions with Ichigo. He is good friends with fellow student Mizuiro Kōjima, whose calm, innocent demeanor and success with women serve as a foil to Keigo's impulsive, wannabe personality.
At first glance, Keigo appears to be a shallow character with a passion for slacking off. Indeed, he takes great pride in not making the honors roster (ranking higher than 50th) and labels those who do so "traitors" (including Ichigo and Chad, who ranked 23rd and 11th, respectively). However, Mizuiro states that Keigo is much smarter than his bad grades indicate.
Later, it is revealed that Keigo can see ghosts and even soul reapers, during the Hueco Mundo/Arrancar arc. The first soul reaper Keigo ever saw was Ikkaku Madarame, who saved him from an arrancar. Keigo also saw Ichigo in soul reaper form, before Ichigo left for Hueco Mundo at Urahara's underground training site, with Tatsuki and Mizuiro.
