- "Eh? Takamina said I was suspicious? Is it because I’m tall? To say that Mariko is tall enough to use a blunt weapon from above… Besides, I had no problems with Renacchi. She is cute and a good girl. Isn’t there some other girl who has a motive? Like for example, people who lost to Renacchi in the janken tournament… Ah, but at that time Renacchi was a research student so maybe she wasn’t in it… But really, it’s not me."
