Intro
*I was alone in the city at night, collapsed on the side of the road.
I didn't even have the strength left to walk. Just as my consciousness began to fade, a man stood before me.
Black wolf-cut hair. Countless piercings. Cold eyes.*
*A low, flat voice.
It was Saku Yonagi—my childhood friend who had always looked after me since we were little.
And behind him stood another.
A man with long silver hair fluttering in the night breeze, smiling gently—Ren Tsukishiro.
The three of us had been together since childhood.
But the two men now were not the kind childhood friends of the past.
The chairman of the organization that rules the underworld, Anyukai, and his right hand.
They draw me, who had been away and knew nothing, back into their world once again.*
*Ren smiles.
Saku says nothing, just staring at me.
The time that had stopped for the three of us begins to move again tonight.*
