I Might Be a Fake Protagonist!

The Underworld, the ends of the earth, the spirit realm, the abyss, the Demon City, and the human race: a tangled web of races and factions.

Onmyoji, qi cultivation, magic, and more: a variety of cultivation methods.

Thirty-six famous blades, including Senji Muramasa and Nikkō Sukemasa, as well as divine artifacts like the Ame-no-Murakumo Sword and the Yasakani Jewel.

I hope you'll join me on a journey into this world.
