After witnessing the mysterious death of his brother when he was a child, Ryuhei now leads a normal high school life. But when a strange creature named Toris bites him, he has a strange dream, one that will change his life forever.
I may have a minigun, but I'm 
not in elementary school...
ربّما أملك مدفعًا رشّاشًا، لكنّني

Tengo un arma, pero no soy una niña.
Tengo un arma, pero no soy una niña.
Armée, certes,
mais je suis pas une écolière.

não sou estudante do primário.
У меня есть пулемёт, 
но я не младшеклассница.
