Kouhei and Kyousuke.

Kyousuke is one of Kouhei's friends. They share the same status: both of them have a little sister.

In episode 12, both of their little sisters sent them to Akihabara (秋葉原?) to buy an eroge during a midnight release.

Sena AkagiEdit

Kouhei's little sister. She is a fujoshi (腐女子?, lit. "rotten girl") who loves to fantasize about men loving each other. Kouhei is a supportive brother to Sena, although Sena doesn't want to admit that she and her older brother are close to each other.

When Sena tells everybody in the Games Research Club that she fantasized Makabe being gang-raped by the other club members, it causes Makabe to have a deep trauma. Sena goes wild all of a sudden, and Kyousuke have no other choice but to call Kouhei to calm her down.


  • In episode 10 of the anime series, Kyousuke, while introducing to Kanako as Ayase's manager, Kyousuke introduced himself to Kanako as Kouhei Akagi.
