AU D. Gray Man (Most likely gonna be a Yullen, but fluffy) Allen Walker is the newest student at Black Order Academy. How will his new start be? Will his past catch up to him before he can run again? Or will it hit him like the mess it is?

Allen finds a black cat in a alleyway on his way home, the small animal beaten and bloody, but what will happen when the cursed boy takes him home to heal him? Allen x Kanda
