Being the sister of the human in the Star Sanses you have become a target. They try to protect you along with everyone else, but you still manage to get caught. You become a prisoner in Nightmares castle, but it isn't as bad as you thought it would be, considering you once had to deal with abusive parents and all. It isn't way to bad, and you feel more apart of them then you have with the others. Maybe you could help them out?

When you fell, you never met Temmie... for a good reason. Your psycho sister, Chara, came to kill the monsters. You save the life of Sans but, is it just his clothes... or is it your heart feeling weird?
