School for killers. School for assassins. School for drug dealers. Specially, school for Mafias. Meet Xylyn Yildiz, the girl who will enter Helwell University — a university that brings chaos, destruction, ruin, and funerals. Created to train the future successors of the PNTGN. Now, Helwell trains them to kill anyone connected to the first Supreme. Family, relative, or friend. No one is safe.
