Kinako Serizawa

Kyouko's friend, also an otaku. She turns out to be afraid that Kyouko forgot about her and becomes extremely jealous of the Kyouko and Aki dating, claiming Kyouko has changed. But actually, she also is a girl who wants boys to love her, one boy specifically: Haji. She started to stalk him and found his piercing lying somewhere, so finally with an excuse to talk to him, she returned it. But it was a trap, set up by him, just to talk with her, and kissed her on the spot. Afterwards he said he only would have sex with the woman he loved, but that that woman wasn't her, but then she yelled she would teach him about sex, since he still was a virgin. Later he tells her he knew she was virgin herself from the start.
