Ten years ago, grotesque demons poured out of the underworld and turned our world into a living hell. Humanity's only line of defense against this calamity are the "Exorcists"—elite warriors who command a magical power known as Magia. Hokuto Shirase is a student training alongside these very warriors. The catch? His magic level is exactly... zero. Unable to even scratch the magical barriers protecting the demons, Hokuto was branded as total dead weight on the battlefield. But when his comrades are pushed to the brink of death, Hokuto unleashes a devastating, magic-less combat style that turns the tide of war time and time again. "Just who the hell is this guy!?" Watch as a boy with zero magic completely shatters the common sense of the battlefield!

Count’s daughter Ashley has decided to devote her entire life to her idol, the knight Clive. But just as her feelings solidify, an engagement is arranged between her and another man. Unable to give up on Clive, Ashley hatches a wild plan: for the one year before her marriage, she will disguise herself as a boy and infiltrate the knight order, just to stay close enough to “breathe the air he breathes.” “Please, let me drink the water you used to wash your shirt!!” “Get away from me, you pervert!”
