~*Oneshots*~ AU Undertale Character x Reader

AU Sans' x Reader (Mostly Ink tho...) *FLUFF*

(QUICK A/N: Some parts of this one-shot was inspired by Glitchtale and other AUs/ATs. So yeah...)

"You guys can't kill her! Please!" Bella tried to reason. Underfell Sans scoffed...somehow.

"Why not? She's gonna erase every timeline and alternate universes. Even the original one. If she succeeds, then we're all dead. We need to kill her. Even Xtale Chara got wrecked by her. Not to mention that Xtale Chara was a hard person to beat." Underfell Sans told her. Still, Bella was stubborn.

"I... I can reason with her! (Y/N) is still in there, I can feel it. The real (Y/N) is still suffering. I just have to take out all the HATRED from her soul. Then she'll be back to normal!" Bella persisted. Original Sans butt in the conversation.

"Kid, even IF you somehow take out the HATRED in her soul. Are you sure she'll be 'back to normal'?" Classic emphasized. Bella nodded. "How are you even so sure about this?"

"Because... she was my best friend. A long time ago. Like, four years ago.. Before she... disappeared." Bella quietly said. "And I know her more than anyone else. Because I'm practically the only person she actually opened up to."

"Wait, hold up, 'disappeared'? What do you mean by; 'disappeared'?" Outertale Sans asked. Bella became quiet.

"She... she climbed up Mt. Ebott. And... never came back. All we got was a note she left. She apologized to everyone and said that she... 'lost her interest to continue'... And..." Bella went completely quiet. She looked away. "Actually seeing her right now. With this dark substance in her... Makes me wonder if she ever was happy... If she ever... moved on from her dark past... I guess... she hasn't. She just keeps remembering the bad events that happened. The bad people who made her like this."

Nobody said a word. Bella looked up at the ceiling. "So just give me a chance to save her from this... this darkness.. Let me save her from herself. She's suffering. I can feel it. Every time she puts on that false smile. I know that she never wanted this. She just wants the pain to stop."

"She just wants somebody to understand her. And... I can do that. I can help her. She's been through a lot. I would tell you what she's been through. But, I don't think I should break a promise. I promised her that I'd never tell anyone what she told me." Bella said. "Maybe she'd tell you that herself after this."

...

So it's been awhile now. Bella and the Sans' have planned it all. If they somehow cornered you. They would let Bella enter a fight with you, and talk to you through out the fight. And if that didn't work. They had no choice but to kill you.

You were walking through the castle. Underfell Asgore's castle. So you've hurt everyone. Physically I mean. But you never killed them. You hurt them to a point of them being weakened enough to spare. All you really needed was the hate from the people you hurt to fuel your soul. And determination.

You were finally at the Judgment Hall. You encountered Bella. You didn't say anything.

"(Y/N)...? Are you... in there? It's me... Bella. Come on.. Don't you remember me..?" Bella asked you. You you grit your teeth as you felt the hatred in your soul decrease a bit. You closed your eyes. And opened them. Your eyes were pure black but the red pupils glowing. HATRED and DERTERMINATION.

"I don't remember any BELLA. Especially, from the surface." You said demonically.

"Please... Don't let me fight you." Bella said. You tilted your head as your knife glowed red. You laughed demonically.

"Who do you think you are...? Telling me not to fight? You have no control over me. Nobody ever will. NOT ANYMORE." You said. A fight started. "Let's see how long you'll survive. You dare speak to me with this comfort about the surface? You don't deserve MERCY..."
