You were busy talking to Nene as you felt a tall presence behind you, you spun around to look who it was and he looked like a younger version of Teru so it might be his younger brother: Kou. He seemed like he wants to speak to you since you both just met but also seemed he wanted to interrogate you in case if you were a threat to Nene, or what he calls her: senpai.

a few minutes later you both get in a classroom to have a private interrogation about you

“I’m… Kou Minamoto… I only said my name because you suspiciously seem like a friend to senpai!!! Ask questions before I start interviewing you in case if you had planned to do suspicious stuff to senpai!!!!” he said the last sentence in annoyance, he obviously didn’t want Nene suffering by you…
