    Summary

    It's been more than twenty years since you fell. You're not sure how long, exactly... long enough for six human children to fall and die in the underground.
    You've given up on saving them, almost, mostly, but you won't just stand by and do nothing.
    You won’t let another child die here. Not if you can save them.

    50,000 words about Chara being tortured and adopting a kid.

    Summary

    It's not what you asked for.

    For one, when you came here, you were not expecting to survive for as long as you have.

    Two, you don't want to be here.

    And three, you don't think this is right for you. You don't think it's a good idea to stay; you shouldn't be here. Yet, here you are.

    It's not what you asked for, but... Maybe that will turn out to be a good thing.

    Summary

    Ah, an office. A paper supply office. You'd think working there would be boring, quiet, but it isn't exactly like that. With two branches who hate each other merging into one, and a power obsessed person placed in second command, things will definitely get interesting in the Eastern branch. Drama will ensue, romance will blossom, and much more will happen in this office.

    While the skeletons have to sell paper stacks.

    Summary

    You’ve dealt with a lot of rejection in your life. No matter how many times it happens, the sting still hurts. It’s the worst experience in the world.

    Or so you thought.

    But what if it turns out the opposite, having someone try to express his endearment toward you, ends up being the most unsafe, twisted, and damaging thing to your soul and your sanity?

    Summary

    (Y/n), a high ranking Platoon Commander in the Military, was on a mission with her squad when her plane was shot down by an enemy ship, leaving her stranded on an unknown island, with none of her comrades in sight.

    It would have been all fine an' dandy... if she wasn't surrounded by three Alpha Skeletons and one Omega Skeleton. All of which want to fuck or be fucked by her.

    So now here she is, having to assess her dominance as an “Alpha” to get by with her limbs still attached and her clothes still in one piece. Even if one of them looks like he came straight from Satan's asshole.

    Summary

    *The Emptiness of the Black Omnivoid is unsettling. Various colored orbs of light can be seen from far and wide, each one representing a Multiverse.

    *There's a white, slightly glitched figure floating in front of one of them, watching it. There are no other features aside from the fact that they look vaguely human.

    *The figure turned around, and from the way that they sound they're smiling, if not a little shocked.

    "Oh! Hello there!" They said. "I'm Spirit."
