He became a third-rate villain in a messy game.

Talent 0, Personality -100, Destruction D-1. I've been possessed by a third-rate villain in a game I created. I'm destined to be killed by the protagonist tomorrow. There's no system, no skill, no talent. The only thing I can trust is the 'setting error' of this game that only I know of . I was just struggling to survive, but the original protagonist started to become corrupt because of me.
