Akane Maniax follows Gouda Jouji, a hot-blooded transfer student whose original dream of reaching Koshien has already become impossible by the time he arrives at Hakuryo Hiiragi. On his very first day, he loudly declares both his baseball ambitions and his love for Suzumiya Akane, immediately making himself the center of attention in class. Akane rejects his sudden confession, but Jouji refuses to give up and begins pursuing her with the same reckless sincerity he brings to baseball.
