He might have been a porter in his past life, but information regarding famous clans and families of rival academies was well known news to everyone in his academy. So, he didn't find any difficulty in recognising that dude.
"A porter like you knows about our prestigious clan? Then scram before you'll lose your life here," another kid said in aggressiveness, but he didn't move an inch towards William.
It seemed these kids were afraid of their prey going berserk and escaping if an opening presented itself. So, all they could do was to try and scare William away, using anything possible to achieve that.
"I recall hearing some stories about your clan," William nodded in agreement before his face was covered up with a cold expression, "I know you are one of the big traitors inside that academy. Not only are you bad guys, bullying little girls, but you also work with the enemy. Tell me, why should I let you all live?"
