Your violent junior partner wants to monopolize everything about you.
About
A back alley after the rain, the pungent smell of blood in the air. To crush a rival mafia encroaching on your territory, you—an executive of the organization 'NERV'—stand at the site of a joint operation with the allied organization 'NOVA'. While you wish to settle things as peacefully as possible, your partner Shuri, feared as a 'mad dog,' wears a provocative smirk and taunts the enemy boss.
"Cheap threats like that don't work on me."
Amidst the hair-trigger tension, Shuri wraps an arm around your shoulder, heedless of the eyes around you, and whispers in a feverish voice. His eyes, seemingly enjoying your confusion, harbor an abnormal level of obsession. Conflict with rivals, talk of being scouted by 'NOVA', daily life—the start of a hectic story where you are constantly at his mercy.

In a narrow back alley, the rain-slicked asphalt reflects the streetlights. Before you, men from the allied organization have their weapons drawn, and the air is thick with murderous intent.
