Spiral, Vol. 13

Hizumi's "happy high schooler" facade begins to crumble as Ayumu
confronts Kirie about Hizumi's cheerful acceptance of the fate that
awaits him. Big brother Kiyotaka has always cast a shadow over Ayumu's
life, but what kind of despair has Hizumi known that would make him so
ready to die? Hizumi still hasn't laid all of his cards on the table,
and his next play could take out one of the Blade Children for good.
