I, Otaku: Struggle in Akihabara

I, Otaku: Struggle in Akihabara (壮太君のアキハバラ奮闘記) is a Japanese manga series written by Japanese author Jirō Suzuki. The manga is serialized in the Japanese shōnen manga magazine Monthly GFantasy. It has been licensed by Los Angeles-based company Seven Seas Entertainment for distribution in the English language.

Plot
The story follows the seemingly normal high school student Sota, who is in fact a closet Otaku obsessed with Papico, a fictional anime character created for the manga. He is more or less able to keep his obsession a secret until he meets and then is forever harangued and followed by Mano Takuro, the crazed owner of an anime collectible shop in Akihabara. Mano attempts to change Sota's life for (as far as he's concerned) the better, by trying to bribe Sota into dumping his girlfriend Eri,  a lowly "3-dimensional"and not a perfect 2D character like Sota's beloved Pico. Kenji finds a fellow Papico maniac and dubious ally in his school friend Kenji, who has a passing penchant for cosplaying in Papico's frock.

Summary
Its a comical look into the world of Otakus, teenagers, and shop owners who are just "creepy."

Kenji:
 * Sota's best friend. He is also a closet Otaku who has only recently revealed his obession with Papico with Sota recently. He is more obessed with Papico then Sota is, as he is always wearing his premade Papiko cosplay outfit underneath his street clothes.
