“Cuteness is invincible!” Day after day, the mysterious girl Mira appears, causing chaos as she tries to steal the hero’s transformation belt. After being rebuilt by the doctor, Mira has reached her full power — but her new form is that of an irresistibly cute girl! Based on the theory that “a hero will never raise his hand against women or children” and “justice can’t defeat cuteness,” Mira is ordered to make the hero fall in love with her and take his belt. However, the hero believes love only brings trouble. Even as he struggles against Mira’s overwhelming charm, he swears he will never fall in love with her. Thus begins a romantic comedy where justice and evil clash head-on, neither willing to give in to the other!
