In a world that has forgotten God, demons have begun to appear. Two "angels", in the form of two powerful transforming heroes, have emerged: but they can't cooperate to save their lives, in both ordinary life and when they're fighting evil!
"Mad Dog" Segawa, a.k.a the superhero Avalon, is a thug who wants to become a fine and upstanding person in his everyday life. Meanwhile Mitsuki, the hardworking and uptight student council president and daughter of a prestigious family, just wants to shrug off her restrictions and live freely.
Neither of them knows that the other is the opposite hero... how will this strange situation play out!
