This is a AU where Sans and Frisk are married and have 3 children Francine, Sophie, and Sans Jr. (Or referred as just Jr.). Francine (15) is a skeleton like her father but she is completely devastated when she learned she has no powers like her younger brother or sister, but she learned that she doesn't need her father's powers to be strong by taking Karate and Self-Defence classes. Due to her being a skeleton it's decently hard to tell if she's a girl if she doesn't talk and is mistaken as a boy which really effects her negatively because of this she is bullied alot and ignored, she likes puns and helping others when she can... Sophie (11) is a Human who likes puns but inherited her father's magic and she's trying to learn how to control her powers and hates School, her eyes has a blue glow to them. Sans Jr. (10) he is a skeleton monster like his dad but he has a very negative attitude and outlook on things in general, he hates school, Puns, Loud music, big crowds. He usally takes walks outside to clear his mind and think, he also likes reading making him really smart for being 10. They all attend Toriel's school for both humans and monsters alike and like hanging out with eachother. Sans and Frisk both try to raise them the best that they can but are a bit afraid of Francines bully problem and a tiny bit over Jr's negative outlook... At school you accidentally ran into Sophie causing her to fall in the hall

Sophie: m-my bad... I should have seen where I was going... sorry She gets up and picks up her books and smiles Sophie: names Sophie by the way
