    Summary

    [Y/N] [L/N] is a powerful mage with a bloodline well-known throughout the ages and her family have always been celebrated. They, however, despise how their bloodline trapped monsters beneath the ground. But, that is for another day. In not being able to afford basic accommodation for university, they had to rely on an old (and terrible) friend named Bethany. For some reason, most of Bethany's skeleton mates despise [Y/N] but why is that? Apart from the fact she is a mage?
    Just because she has a kindness soul, it doesn't mean she will stand for their bullshit.

    Summary

    "Just... let me die, if that's what you want," I spoke, broken and quietly.

    A low rumble of laughter was heard from across the room. "Let you die? That's a concept... but, unfortunately, it is also a mercy I am not willing to grant you."

    Summary

    Nightmare was patient. Like his brother, he let his emotions collect inside of him until they bubbled over and spilled out in the form of dark, passionate rage.

    Regardless, his patience served him. It allowed him to study others, and know exactly how to hurt them. How to draw out the most negativity. So that of his anger, one good thing would come at the very least.

    So that he could feed.

    Summary

    In a Multiverse where Ink and Error retire together after falling in love. Dream is now the new leader of the Star Sans and protector of the multiverse.

    With Error no longer a threat, Dream focuses his effort in pacifying the other big threat to the multiverse, his brother Nightmare. In an attempt to cure his brother of his curse of negativity, Dream uses a rather volatile serum from a rather lewd AU.

    How will this series of events play out? And how will the multiverse fair without Ink and Error?

    Summary

    《明日の星と月》|| [Bad/Star Sanses fan-story] || [Undertale AU]

    -------------------------

    "...since we are going to fight all the Pinnacle entities together.. I want us to be actually working together to fight them. I know protecting something is not your thing, but we have no choice but to do it together, brother." Dream said,

    "...all right. We'll work together." Nightmare stopped for a second, "But.. once this is all over, we'll go back to what we always do."

    "Of course. We'll also go back stopping you from causing negative feelings and destructions in the multiverse." Dream said.

    Since then The Bad Sanses and The Star Sanses worked together to fight the Pinnacle that threatens their world. With the 9 of them, will they able to destroy the Pinnacle even if they worked together?

    ------------------------------------------------------

    Enjoy!

    "I can't give you an answer to that. It's your decision, but we can't help you if you chose to leave."

     

    Who knew that the Bad Sanses, some of the most feared villain's in the multiverse, would get tired of fighting? Well they didn't, that's for sure. They also didn't know that the strange being they allowed to wander around the hideout would send them to an AU they can't get out of.

    As for what the girls stuck with watching them think of the situation? The frying pan Killer got hit in the face with speaks for it self.
