Amidst a violent snow storm up in the mountains, two demons were sent out to extinguish the last living relations to the sun breathers. The Kamados. "Oi stop messing around you woman obsessed freak!" "Come on don't be so up tight!" "Huh... what's this?" A small child appeared from behind a snow covered bush, a small note tied to his neck as his bright red eyes stared at them inquisitively. "Tanjiro Kamado... you don't say" **** "You are to infiltrate the demon slayer corps and gain their trust Tanjiro. I'll always be with you, don't forget that" the demon king stated, his tone surprisingly soft. "Yes father"

In this story, Tanjiro wasn't able to become a human after the fight against muzan and becomes the new king of demons. Now in the modern era, tanjiro is attempting to create a serum using his blood to make his demons walk under the sun. But he discovers the new hashiras of the now demon slayer are the same hashiras he met in the past. And that is when he gets worried, because he remembers their strength. But using whats left of his humanity to create a drug that will weaken him so much giving the slayers a chance to kill him. But most of his humanity is now gone. The now modern hashiras remember their past lives and nezuko, Zenitsu, and inoskue remember their past lives.

Part of him wished he'd been late, but it was too late as the monster before him was ruthless. He tore the family apart, killing all. All Giyuu could do was watch in defeat until his turn came. He knew death only waited. This was his end. Or so he thought. Turns out, the world had other plans for him. Plans that revolved around a certain maroon haired boy who would be the turning point in the future.

Yoriichi had once been the best swordsman. Even as an Omega, he was feared by Demons. But choices led to his leave. What choices might have forced this conclusion? His love for the Demon King, Muzan Kibutsuji. His one and only mate. His destiny.

Will be a long series I do, following through the years of Tanjirou's growth. Drama, fluff, and multiple relationships are guaranteed in this adventure.)
