Manabu Kuchiki is one of the main characters from the Genshiken anime and manga.
Kuchiki becomes a full-member of Genshiken together with Ogiue in volume four apparently after being kicked out of the Anime Club. He wants to be nicknamed Kuchi and enjoys it when people use this nickname.
It is revealed that Kuchiki doesn't need to look for a job since he's pretty much guaranteed to have a job at a local bank thanks to family connections.
In the AWA fics, Manabu made his debut at the sixteenth chapter of All Worlds Alliance Stories.
Kuchiki is tall with a short haircut and a long, oblong-shaped face with a pursed lips.
Kuchiki is a very abrasive individual, with a loud and obnoxious style of speech and hyperactive mannerisms that often offend others. He has no qualms about doing indecent or improper things that get him in trouble, such as spying on Ogiue when she first joined, and is frequently beaten throughout the series following failed sexual assaults against both women and men in the club.
Kuchiki knows that his personality is off-putting but most often his intentions are good, such as when he caught a thief during the school fair and annoyed him into returning the stolen goods. He is actually the second-best fighting game player in Genshiken, next to Kousaka. He twice expects himself to be named the next Genshiken president, only to be passed over by Ohno and then Ogiue. Mostly a background comedic character, Kuchiki is used as a goad for a good many of Genshiken's slapstick and off-color jokes. One might even consider him a boke to the rest of the Genshiken's tsukkomi.
- Joins the series about midway. Butt-Monkey who's even more Proud to Be a Geek than Madarame. His actions are partially the reason why the Genshiken is so small, especially near the end of the series.
