VOICES - The Seventh Soul [English Version] A failed experiment has unleashed two shadow demons-creatures that feed on their victims' deepest fears and self-hatred. For Frisk and Sans, scarred by painful memories, these demons embody sorrow and despair. In the Underground, they fight against the shadows and their own inner darkness, but the closer they grow to one another, the stronger the grip of despair becomes. Their only hope lies in a fragile bond-love and friendship that must resist the voices of madness.

THIS IS BEING REWRITTEN BOTH HERE AND ON MY AO3 "AppleBloomer" Cross was a loyal servant to Nightmare, even proving he would give his life to save his king. Nightmare had plenty of secrets hidden within himself. Until a small fit of rage gave away his true emotions for Cross. Cross had to face Nightmares growing emotions towards him, while dealing with a threat that could end their whole world. Ark Two: When Cross feels the happiest, things are pulled away from him when a long lost part of himself awakens with the soul purpose of tearing his life apart. Without a voice, he has to figure out how to take back his life from the one person who could destroy it all. The hints are slow, but maybe Nightmare will get it.

(TW: unaliving thoughts and memories at the beginning. It gets better over time, don't worry! Trauma is difficult to overcome...) You didn't want a second chance. You didn't want to survive. You wanted the sweet release of death. But it seemed like the universe was far too cruel to allow you even that. It took away your memories, your free will to choose whether you live or die...hell, it took the one thing in life you owned! Your own name! And now it seemed like you had to live yet another cruel life, doing things you never wanted done to others. But...at least you could do things your way. Maybe this second chance wouldn't be so bad... (Reincarnated as Nightmare Sans, but unlike other stories, you have no clue what Undertale even is) (WE REACHED NUMBER 1 IN THE UNDERTALE TAG YOOOOOOOO) (9/13/25)

Rewards: #1 Crossmare #1 IN UNDERTALE?!?! ARE YOU SERIOUS?!?! *** There wasn't a creature in the entire multiverse quite like Nightmare. Most viewed him as an insane overlord high on power, but he radiated far too much calculation and control for blind madness to be the cause of his personality. No, he was smart. Incredibly so. He best be, as he ran an entire kingdom of misery and suffering just out of reach from the universe's nosey "Saviors." Cross had a difficult time deciphering his master's intentions. One may argue that he had no choice in being the ravenous king he is now, but that life had forced him down the path long ago for the sake of feeding. That's what this is all for after all. The pain and suffering. It was to feed the king. Cross couldn't despise him for such a basic necessity, no matter how foreign the concept and how often hunger turned the king's attention his way.

He had been serving 'the one who takes' for quite some years. Most of the creatures in the batches of new recruits either died or betrayed their king. But Cross would never do that. The god had given him a home, friends, a new purpose, a second chance at life to prove his worth. In exchange Cross served him, stayed by his side, devoted his life to him in such a manner that it almost could be called worshiping. He was a god, afterall. Cross knew he would do anything for Nightmare. He'd kill for him, had killed for him, he'd protect him, even die for him. And if that couldn't be achieved, well, then he'd die with him.

F!god is from harrish6 and I was inspired by " Lovesick: The Last Cure" created by @glitchy_protecter. none of the pictures are mine. Error basically gets a harem. Inks Will find out WHY he destroys and regrets everything he's ever done to him and the others in the council. They latter realize how innocent Error really is and see how much of a cute bean he is. Warning! Swearing Sexual content Mature Possessiveness Imprisonment
