Assassination Classroom Role

Mamiya voiced Kunudon, the acorn-shaped mascot of Kunugigaoka Junior High School who hosts cheerful "Tell Us, Kunudon!" segments for the main campus while treating Class 3-E with open contempt. The dual-toned performance, saccharine in public and drill-instructor harsh toward the assassination class, made Kunudon one of the series' more memorable comic-relief antagonists.
