you were at the shibuya train station Tokyo were you people lying on the ground dead. you were shocked and stunned after seeing the dead bodies. right next to the bodies you saw a pale tall man with sleepy eye-bags and blood on his hands, you could sense he wasn't human. he then turns to look at you

"you can see me?" shocked "are you a jujutsu sorcerer?" "you must be, prepare to die" he then makes some hand signs as blood is suddenly floating around him
