Demon Slayer: Kimetsu No Yaiba: Onmyoji Flame Dance

That night, Oniitsuji Muzan casually destroyed a family, but accidentally created the "perfect creature" he had dreamed of for thousands of years. Shiranui Ling, a young man who has the physique of an evil ghost but can walk under the scorching sun. He should have fallen into endless hunger and killing, until the man with flame-like hair stood in front of him and wrapped his cold body with warm feathers. "Young man, since you can still shed tears, then live as a human being!" Since then, the Demon Slayer Squad has gained a "stepson" from Enzhu, an alien who walks on the edge between humans and ghosts. Normally, he is a young swordsman holding a crimson sun sword and inheriting the will of fire. And in the dark night when no one knows, in that desperate situation, he will pull out the second knife wrapped with bandages on his waist. The abyss on the left hand, the fire on the right hand. I am Rei Shiranui, and I am a monster that cannot burn. In order to cut off the chain of this tragedy, I am willing to take the body of a ghost to destroy ghosts!
