Hidan no Aria

Super powered kids go to a school that teaches them how to fight.Hidan no Aria is more of a harem/action while soul eater is more of a shounen.The school in Soul Eater is always super natural while in Hidan no Aria only a few classes are.And in both shows the main Charcthers take contracts.
