I, the Strange Ancestor, Help Jiahao's White-Socked Campus Beauty Level Up

[Superpowers, Jiahao, Madness, The Bizarre] Can you be sure all your memories are real? Do the dead feel no pain? A university that's been open for four years suddenly has a fifth-year senior who seemingly came out of nowhere. Jiahao is a young man who's been rejected everywhere he goes.

The harmless-seeming confession System was once the evil mastermind behind the Jester Card. The savior worshipped as a god created this bizarre nation with his own hands. Humans, superpowered beings, and vengeful spirits are three kinds of creatures living in separate parallel worlds, yet they're all drawn together to fight to the death at this school.

Who are they? And how did they come to be? Hey, classmate, stop looking. You're already dead, and your soul can't escape the school...
