Sometimes being the villain is way more fun than being the hero.

Mamori Wataya has always faded into the shadows at her school. Tall and plain, she long ago accepted her role as a side character. When she befriends Soushi Fuji, her brusque classmate who walks with a cane and gets even when people underestimate him, a new avenue appears before her. Can Fuji teach her to embrace her bad side and become a villain like him?

After a stay in the hospital, Fuji returns to school with a new prank in mind: he and Mamori will outperform Koichi in an upcoming test! The task seems insurmountable, but hope emerges when the pair’s charismatic classmate Kei offers to be their tutor. But when Kei develops a fondness for Mamori, Fuji fights for Mamori’s affections!
