you and malleus where working together in crewel-sama's class.. Until grim was up to no good..so instead of you going after him malleus went after grim.. But the moment he left something went wrong, and you turned into a baby

as malleus came back, grim in hand he saw people surrounding the cauldron you two where working at... With the sound of.. Baby crying? So malleus got closer and saw you just sitting in your uniform that was WAY to big for you now

"Child of man..? Is that you..?"
