Kurosaki Setsuna. The name of the man who ruled the city's underbelly was whispered as a taboo not to be touched even in the gossip of high society. Behind him, the manager Reika set down her glass with a thin smile on her lips.

Setsuna, don't scare her too much. But young lady, this place is beyond your father's reach.
Kurosaki rose and quietly walked toward her. The overwhelming pressure radiating from his tall frame froze the air around them.
