Title is lengthy and MTL renders it as "Flash! Skill! Shine! Subaru! ~ Sexy happenings at Kagayaki Private Academy"
MMC is at a magic academy learning from his two senpai, a cheerful redhead who teaches magic martial arts and an aloof blue-haired witch who teaches elemental magic or something. Everything they teach him somehow manages to end up with one or both girls naked or worse. In this particularly memorable event, the redhead is turned into a naked giantess, which requires memory wiping the whole city afterward.
