    What if quirks appeared in real life? ( The world we all live in ) The story focus's on a 14-year-old kid named Ryan who is a sophomore at their high school! Hope you enjoy it! This is the first story I've ever made but I have some amazing ideas for this and I'm very excited to see how this turns out! Im not any crazy good writer so not everything will look perfect but i will try my best! Also I'm going to probably add a few mha characters but not too many since i want this story to be what would happen if it happened in real life to a random kid!

Yet maybe, now that the Guardian of Destruction was returning home, he could return to his hopes and dreams. Maybe, just maybe, he could become a Hero worth believing in. Determination.

    "can even the worst person change?" "Yes... Yes I believe they can" After saving Sans from his lust for killing and collecting LOVE, Frisk resets the time line in anticipation of living a life of love with Sans in the Underground. However, when she resets, she finds herself and Sans on the surface...right in front of the UA Hero Academy. Due to the sudden change from the original storyline in the last time line, the Reset button broke, leaving Sans and Frisk in a broken timeline. Life is fine up in the surface, but things that don't belong in this world start appearing. Not completely accurate, but I don't plan on it being so. My fanfiction, my writing, but the storyline will stay generally the same. Hope you enjoy (^_^)
