This is a world invaded countless times by dimensions, and human civilization has suffered an unprecedented blow.
People enter secret realms and ruins, acquire the talents and abilities of heroes and monsters, drive out the invading creatures, and rebuild their homes.

Su Zhe: "Teacher, I want to make a contract with the C-rank hero, the caped baldy Saitama!"
