    Summary

    When a force outside of fate intervenes, it throws everything out of balance. Right as Tanjiro, Zenitsu, Nezuko, and Inosuke take off to go to the mission at Mt. Natagumo, they are forcibly dragged to a strange place. They aren't the only people either, slayers and the likes show up as well. The place they've been dragged to is strange as well, and escape seems impossible. Not only that, but the person who brought them here doesn't seem quite human or demon.

    Summary

    Ubuyashiki Amane is the wife of the leader of the Demon Slayers. She is a priestess. She has known horror and carnage. She has sat through reports of Slayers who were the only survivors of their groups, who can barely get through the words without crying for the lost or biting back pain from the demon’s blows. She has knelt beside doctors as they hold injured Slayers together, held teenagers down as they are treated for life-threatening wounds, and comforted warriors on their deathbeds as they fade from here to heaven. She is a mother, not just to her five children, but to every person in the Corps, and she holds that esteem in high honor. And every time, no matter how stoic she manages to keep herself, there is never a way to prepare for carnage. 

    The smell of blood and rot infests her nose as she climbs the mountain to the Tokito children’s home with Nichika and Hinaki, and those smells can only mean something is deeply, deadly wrong. 

    It takes everything she can not to sprint up the path and leave her children behind.

    Summary

    She doesn't remember when she stopped…breathing? Existing? She doesn't remember when it all became darkness. Darker than sleep. How does she know she is a she? She just does.

    Bumb…Bump Bumb…Bumb…Bump Bumb…Bumb…Bump Bumb…

    Over and over like a rhythmic clock. Being in that nothing for so long made almost everything she now feels irritating.

    Or...

    Sumire is a reincarnated soul that died peacefully in her first life but but awakens way too early into her next life: Her new goals- Keep her family alive, specifically that white haired muscles for brains idiot she so loves.
