The Mob Character Who Woke Up!

Kaizen Renji Asahina was an NPC in a popular RPG, designed only to sit in class, nod on cue, and say three recycled dialogue lines. But one day, something glitches and he wakes up. Suddenly aware, trapped inside the Academy of Heroes, Kaizen must survive: A Demon King candidate as his overly earnest roommate. A terrorist student club that crowns him “Lord Shadow.” An Inquisitor waiting for any excuse to turn the academy into a warzone. He’s just an NPC. Why is he the center of the story now!?
