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. However, she later returned to pursue her love for him. Before she could cut him with her saika, Anri appeared to save him. After Takashi found out that Anri controlled the real Saika, he ran off. He was last seen desperately trying to mug Shizuo Heiwajima, but the incident ends as expected, with Shizuo knocking Takashi out. Takashi hasn't been heard from since.
