Description: mini story - Human did a reset, but it malfunctioned, everyone suddenly started having major nose bleeds and their attitudes changed, they were more angry or either cocky Sans Info - HATES the colour Blue, so he spray painted the blue with red, his favourite colour he is always cocky, even when near death pretty angry aswell, but never sad
