After a thousand years of fighting an Evil God in another world, Choi Hyunwoo finally returns to modern Earth.

Unfortunately, things have changed.

These days, everyone is obsessed with Slayers, their ranks, and who's stronger than whom.

Hyunwoo couldn't care less.

He's more interested in comic books, terrible mint-chocolate cooking, and finding somewhere quiet to escape his sister's nagging. After all, he already spent a thousand years saving another world. Surely he's earned the right to be lazy.

Then an old enemy's power appears in an abandoned factory.

Hyunwoo takes care of it before breakfast.

And suddenly, the man who just wanted a peaceful life has once again become the strongest Slayer on Earth.

The only problem is that Hyunwoo has absolutely no intention of acting like one.
