Little mouse

In this universe it's heavily based off of the beastars, the anime, universe. So hotch works for the BAU along with his team, (I'll give a description for each character as part one then part two will be the story start) on a brutal case where the unsub is throwing the team for a loop, so to avoid spending more expenses they call in a helping hand a young 24 year old who has connections with Gideon. (Btw I made the cover I know it's not good but I couldn't really find a picture that looked good so yea))
