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, kind-hearted 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.
