Takashi Nasujima

Takashi Nasujima is a teacher at Raira Academy. He would talk to Anri Sonohara, but as soon as Masaomi Kida would show up, Takashi would leave.

Before he targeted Anri, he was in a relationship with Haruna Niekawa. When he learned about Saika, he spurned Haruna and she moved to a different school. After he found out that Anri controlled the real Saika, he vanished.
