Hanten Kousei! Furyou to Onna no Boku

Seeking revenge against a notorious school bully named Sonomura, Mashiba purchases an obscure beverage online that promises to transform him into a rugged, imposing man. However, the mysterious drink produces the exact opposite effect, unexpectedly turning him into a strikingly curvaceous young woman. Despite this bizarre setback, Mashiba quickly discovers a crucial weakness in his target: the tough delinquent is incredibly shy and awkward whenever he interacts with girls. Armed with this knowledge, Mashiba decides to weaponize his new feminine appearance, relentlessly teasing and flirting with Sonomura to fluster him and finally make him pay for his past bullying. The situation escalates when Mashiba learns that Sonomura has resorted to watching adult DVDs in a desperate attempt to build up his resistance to female attention. Outraged by this extreme countermeasure, Mashiba resolves that the bully's audacious actions demand a far more serious punishment. What begins as a calculated scheme for revenge gradually shifts into something much more intense, as Mashiba realizes that getting even will now require taking their provocative encounters to a decidedly more intimate level.
