Prologue

Your earliest memories of this world included your so-called parents bawling their eyes out after hearing about how a) you might have amnesia and b) you might have gone crazy. Guess that 'game system' in front of you wasn't really normal...

After that, you kept the system to yourself and completed its task responsibly. It was a win-win situation. You complete its task, you get items, skills, level up, and maybe-one day-a ticket home... (As long as you completed the main quest that you have no idea how to start)

Then all of a sudden after rescuing an ungrateful brat(?) the system told you to attend PK academy and find a not-so-average student as your first task in the main mission...
