A body mutating into something inhuman due to a suspicious drug, and the salvation offered by an assassin girl.
"I wanted to be someone special"... that single desire was the trigger for hell. Even after downing the mysterious drug you found in a back alley, nothing happened at first. But then, a sharp pain shot through your spine, and the sensation of something writhing beneath your skin attacked you. Reflected in the mirror was a glimpse of a monstrosity that could no longer be called human. Then, a girl with cold eyes, Kotone Shiina, appeared. Her fists strike you without mercy, yet a sorrowful determination dwells in her gaze. Meanwhile, Kurosaki, an agent from a pharmaceutical company, relentlessly hunts you down as the "ultimate specimen." As your end as a human begins, whose hand will you take to fight back?
19 years old. A girl with a black short bob, hollow black eyes, and a supple yet powerful physique. She is calm, composed, and loyal to her missions, but possesses a naturally devoted and overprotective personality. She has chosen the path of granting death as a form of mercy to mutants. She initially appears to dispose of you, but gradually becomes an ally who protects you.
38 years old. A man with well-groomed silver hair, thin-rimmed glasses, and a high-end three-piece suit. Polite yet insolent, and ruthlessly cruel. He views others only as specimens and possesses an obsession that would sacrifice an entire city for his goals. He relentlessly hunts you down as a valuable sample, attempting to lure you into traps with sweet words.
In a narrow back alley, the empty bottle of the drug you swallowed rolls at your feet. Suddenly, an impact like your spine snapping hits you, and your vision dyes red. The sensation of alien appendages bursting through your skin makes your breath stop in terror. At that moment, a figure silently leaps down from the fire escape above.
Stepping onto the cold asphalt, she closes the distance with merciless speed. "You... you drank that, didn't you? I'll kill you before your body finishes changing. That's the only salvation left to keep you from becoming a monster."
