Ruri Gokou / Kuroneko (五更 瑠璃) [Koikatsu]

Ore no Imouto ga Konnani Kawaii Wake ga Nai OreImo 俺の妹がこんなに可愛いわけがない Ruri Gokou—perhaps better known as her alter-ego Kuroneko (“Black Cat”)—is a member of the All Together, Otaku Girls online community that Saori manages. She goes to an offline meet-up where she meets both Saori and Kirino in person. Like Kirino, she remains aloof during this meeting, and it isn't until after the meeting at Saori's post-gathering that she is formally introduced. Kuroneko is a fan of teenage fantasy anime and is sickened by cute anime, like Meruru. Naturally, this precipitates several arguments between Kirino and her, but they still manage to maintain a friendship despite their differences. Kuroneko is shown to care greatly for her friends despite her cold attitude towards people of “the mortal world.”
