Nagi: the king of video games. Chiharu: the knight of light novels.  Kayura: the soldier of cosplay. The three powerful individuals meet by chance in the holy land of Akihabara.  Tsugumi becomes a bystander, not being able to predict the result of the battle that she was the cause of.  Then Hayate mutters, “I’m sorry…”

No podría importarme menos si eres mi hermana o no.
