❤ ~ The Greatest Gift ~ ❤

▫◽◻1️⃣◻◽▫

This story takes place with a completely altered timeline. Whatever happened in the Anime and Manga, that is not the case here. This is indeed an omega verse, but still present in the Demon Slayer era. Does Not Take Place In A Modern Time AU.

'The Greatest Gift' is a Muzan X Yoriichi for the beginning. Later on, when Tanjirou is older, it will shift into a GiyuTan/RenTan. There will be many things, but Smut between Yoriichi and Muzan is not one of them. It will be heavily fluff, angst, and drama based. Smut may be added later when Tanjirou's relationships become relevant, but that won't be for some time. I hope you all enjoy this adventure. #MamaYoriichiForever<3

Other relationships are welcomed as well, so let me know if you would like a certain ship as a side relation. The more, the merrier. Also, please note that I may drop certain polls at the end of chapters. Those determine which way I may drive the story. Please do vote, even if that outcome is not chosen. I value each opinion.

Lastly, Tanjirou is half Demon and half Human. He physically resembles a human, but possesses Demon arts and strengths similar to a Demon. He is the child of Muzan and Yoriichi in this story, following a neutral role. He simply wants peace between Demons and Humans, due to his circumstances. Tanjirou will always remain the ball of sunshine, so no worries. No evil Sunshine here, so apologies to those that might want a more evil Tanjirou.

That is all the info you need to know about this story. Other than that, hope you enjoy this lengthy adventure and be sure to leave me your feedback throughout! (✿◠‿◠)

Each step was greeted by the crunching of dried leaves. Of the stifled snaps from twigs that broke beneath his weight. The cool morning breeze rolled throughout the thick woodlands, bringing chills along slightly tanned skin. Slight maroon colored hair shifted with each long stride, the black, yet red hues illuminated under the suns bright rays. Those maroon eyes wore worry like a coat, glancing behind with precision. They were wide, crested with caution. Firm hands held the katana tightly, the sheath held within his sash wrapped tightly around a somewhat slender waist. His garments were lose on him, being pulled at with each gust of wind. It made every step harder than the last, but he carried on. Forging ahead without hesitation. It was something that he had to do.

Yoriichi was once a Demon Slayer who lacked most things. He never saw himself as much, only went through the motions of life. Emotions were vacant for the longest time, but a single choice had swiftly pulled that reality away. Every fact that once defined him, was no longer relevant. His once empty expression was now seeping with countless feelings, flooding his own heart as his free hand rested along his stomach. Yoriichi was an Omega, a strong one at that. He never minded being alone since it felt natural. He was an enigma. An Omega that happened to be burdened with an unfortunate fate. What fate might that be?

Simple; he was mated to the worlds greatest enemy. Muzan Kibutsuji.

Most would assume he hated life's choice, but in truth it was not unappealing. He'd always felt something for the other and a mate was permanent. It was simply the morals the Demon held. He valued little, unlike Yoriichi. The two while destined to be together, were simply too different. Yoriichi still sought to protect the innocent, even if he was despised. Muzan sought the elimination of those who defy him, building his own army to besiege the title of ruler. One was good, whilst the other was beyond evil.

That single fact led to Yoriichi's choice to flee. He was willing to offer a chance, but Muzan was no Demon seeking redemption. He had his sights set and Yoriichi knew that. Their relationship was etched into the stars. They'd given it a shot, to make it work. But it was deemed impossible. So long as Muzan remained crested in darkness and bloodlust, there was no hope. But the world often found solutions to prove such theories wrong. That solution should have been impossible, but fate loved to twist luck. To make it irrelevant. Yoriichi was human. Muzan was a Demon.
