A true Wexari ( Sans x Chara )

I made an Au! ( lol, I am so proud of myself. )

If someone already made something similar, please tell me. I wouldn't want to make people mad. T . T

This Au is where Chara is alive. ( this Au is kinda centered on Chara ) Chara is a witch. A wexari. If you've read a certain book series,( I feel like a book worm now ) you could know it is a witch that doesn't need a spell book to cast spells. A wand is optional. As a wexari, Chara needs to learn how to both put boundaries, but also push them at times. The few amount of times she has to go out, not many people are fond of her. They say she's a witch, or demon. Her red eyes being a main reason. No one thinks there's something called a 'good witch'. Chara is on her quest to prove them wrong, all while trying to stop Frisk.

Frisk is a witch that needs a spell book. Luckily for her, no one knows. But, the spell book that Frisk just got sooo lucky to find, has dark magic within it. Frisk is just having this uncontrollable feeling to cast spell after spell when possible. Chara is trying her ( sorry ) best to try to get help. Of course, no one believes her. Will Chara be able to get the real Frisk back before it's too late?
