Lin Xiu accidentally obtained the [Taotie Pattern], gaining a portion of Taotie's power and beginning his journey through different worlds.
On his very first day in another world, he found himself in a terrible situation... A demon had captured him and tied him up.
Then, by a twist of fate, he drank the demon's blood and awakened his own [Spirit-Eating] constitution!
Demons can eat humans, so why can't humans eat demons?
And so, in the world of Demon Slayer, a demon-eater feared by all demons was born!
PS: A crossover series. The first world is Demon Slayer. Re:Zero, Overlord, and Unbreakable Machine-Doll are under consideration.
