Kono Fukushuu ni Gyaru wa Iranai

Nozomi Kashihara has spent his entire life without affection. Orphaned and raised by a criminal syndicate, he ultimately turned his back on the very organization that took him in. Now living as an unremarkable high school student, he keeps his head down and his past buried—until he steps in to rescue a gyaru classmate from a gang of delinquents. The incident unexpectedly draws them together, but as their bond deepens, Kashihara grows increasingly convinced that the girl by his side may actually be a hired killer sent to eliminate him.
