Beyond Humans and Ghosts

[A little angst + Not a saintly protagonist + Multiple heroines]

Yi Jiang, a student who has just graduated from high school, is inexplicably dragged into the business of slaying demons and monsters.

He signs a contract with the world's greatest blade, Slayer of Demons,

and is saddled with a huge debt.

To stay alive a few more years and earn enough to pay it off,

he accepts his fate.
