地元のいじめっ子達に仕返ししようとしたら、別の戦いが始まった。•

Jimoto no Ijimekko-tachi ni Shikaeshi Shiyou to Shitara, Betsu no Tatakai ga Hajimatta.

For most of his childhood, Kotarou Hinode has been relentlessly bullied by three boys: basketball prodigy Kanae Oborozuki, talented wrestler Akira Mikazuki, and gaming genius Shigure Mangetsu. Due to his competitive spirit, Kotarou challenges the trio in their respective fields, only to be defeated over and over again. Still, he remains steadfast, and before moving out, he vows that he will return stronger than ever. Years later, as a high school student, Kotarou transfers back to his hometown, ready to fulfill his vengeance-fueled promise. In a twist of fate, it turns out that the three boys who bullied him back then are actually girls—only now more physically mature and attractive! This revelation does not deter him, however, and Kotarou remains focused on getting revenge. Furthermore, he is oblivious to the fact that the reason why Kanae, Akira, and Shigure used to push him around back then was that all three liked him—a feeling that has not faded in the present.
