Haruna Ikoma, a passionate female teacher assigned to a chaotic school, aims to reform students' consciousness and improve academic performance through her 'New Educational Program = New Corporal Punishment System,' which involves humiliating punishments. Her personality is ignored as she is treated as part of the blackboard, having vibrators or penises forced into her while she writhes in agony. Left in a wall vagina state, subjected to in-out sex... She has no choice but to endure every humiliation.
