Tofu Tofukuji

Tofu Tofukuji is a retired elderly man lodging at the Gochiso apartments. He harbors a hebephilic interest in Fuko Kuzuha shown by his photograph collection littered on his apartment walls. A mostly harmless kindhearted man Tofukuji is often willing to sacrifice his own safety and freedom to help Hibiki or otherwise satisfy his craving for upskirts. He is good friends with Mori Koji.
