1 Vol Zero : chapter zero : Start

My name is Ban and if your wondering how I got here then here it is.A few days after my last assassination job.I got hit by a car which ended as a hit and run on me.So no one knew I got hit and was left to bleed out.But after I died in that world I was put in a new world and did not know what was happening till I heard a old,mysterious,and creepy voice tell me in my head to become the strongest across the multiverse and not die till that happened.
