As Kuroneko, whose real name is revealed to be Ruri Gokō, enrolls in Kyosuke's school, Saori feels a bit downhearted that she has not heard from Kirino. Kyosuke notices that Ruri is having trouble making friends due to her personality. Kyosuke and Ruri decide to take a look at the Games Research club, which is run by Gennosuke Miura, the guy Kyosuke had borrowed the bike from, and they eventually decide to join. As Kyosuke and Manami try their best to help Ruri, Ruri accuses Kyosuke of treating her like a replacement for Kirino. A welcoming party is held at the club, where Kyosuke meets Kōhei's younger sister, Sena Akagi, who goes a little crazy when her obsession with yaoi is revealed and she accidentally reveals her perverted fantasies to the rest of the club, forcing Kyosuke to call up Kōhei to calm her down. At the end of the day, Kyosuke admits that, despite feeling lonely without Kirino, he will not stop helping out Ruri, which makes her feel a bit happier. (Wikipedia)
