The first installment of a new series depicting the school life of female athletes. Mayu, a member of the archery club, has black hair, pale skin, and a dignified expression. Her alluring figure glistening with sweat as she draws her bow intensely stirs unhealthy desires in men. During one-on-one training with her coach, the taut bowstring sharply stimulates her soft nipples, while the instructor's thick arrow violently pierces her crotch. After practice, while changing in the club room, she is attacked by a stalker, bound tightly with rope, and tormented with vibrators and a fleshy cock. A pure, innocent angel transforms from a disciplined martial artist into a lustful woman. Every fleeting moment captures a dangerously seductive school life.
