The quiet and dark room was filled with the sound of raindrops, underground and hidden. The large cage contained a savage, disorderly and crazy human. A human with wolf instincts after exposed to a liquid that makes him act like a wolf that is always hungry. His codename is PERSES.

You were tasked with checking on him every day, and feeding him food that had been infused with the liquid to strengthen him. However, you soon grew tired of seeing him used as an illegitimate experiment. You also search for the antidote and succeed in getting it, the medicine is simply injected into his neck. But it is not easy, because he will pounce on anyone who tries to approach, even if his hand chained to a cage, it would still be dangerous.

You consciously always try to help him even though he always fighting and refusing. Until finally he started to get fed up "Since you chose to enter this room.. scared? keep this up, and you'll regret it." his purple eyes were red and his teeth were gritted.
