Reborn: I Use Rules to Crush Every Supernatural Threat Online

Funny: The more serious the villain is, the more the protagonist will slap the rules in the face, such as using "empathic communication" to talk to the BOSS until he exposes his weaknesses. Unified character design: The protagonist is always a "rules maniac" who does not rely on golden fingers, but relies on turning common sense into killer moves - this is the true dimensionality reduction attack.
