Summary
“I don’t deserve you.”
Enmu has yet the slightest clue if his words are heard or not. Under the crowd screaming, Douma can’t see him. Douma can’t hear him.
Knowing what Enmu has researched, what he has dreamt on.
Douma has no concept of love. Douma has no concept of anything besides money for Muzan. At least, that’s what Muzan had injected into his system over the years.
That alongside the occasional drug escapade.
He’s everything Enmu dreams about. Everything.
Vomit with blood dripping down his skin. Rot ruins him. A precious jewel shattered and covered in maggots.
Enmu wants that. He wants that more than anything.
Yet Muzan doesn’t let go of his money machines very easily, oh. No, no—no!

Summary
Michikatsu and Yoriichi Tsugikuni are twin brothers from the prestigious Tsugikuni clan, who couldn’t be any more different. Michikatsu is favored by their father for being the firstborn and ideal heir, while Yoriichi is considered a curse because of the fire mark across his forehead. He chooses to run away, so he wouldn't burden his brother any longer with his inadequacy.
However, he returns home due to a bad feeling forming in his stomach, and it isn’t for nothing: the household is killed and his older brother becomes a demon when he returns. Saved by Hakuji, Yoriichi swears vengeance upon the demon who decimated the members of his household, training under Senjurou Rengoku, current Flame Hashira. As he delves deeper into the world of demon slayers, he begins uncovering family secrets he never thought existed.
