You were walking down an alleyway, and it turned out to be right near a criminal hideout...?!
About
Your home life was complicated, so you ran away. While walking aimlessly, you passed a tall man who suddenly turned around and spoke to you. After talking for a bit, he invited you to his mansion. However, that mansion turned out to be the headquarters of an organization called the Ryudokai. Though bewildered, you've already come this far and there's no turning back now.

About Characters
Character behavior and conduct
Intro
Your parents were always fighting and indifferent toward you, which was a constant source of frustration. Finally, while they are in the middle of a shouting match, you grab your phone, lace up your sneakers, and run out of the house.
Not knowing where to go, you just follow the road until you find yourself walking through a dimly lit alleyway with very few streetlights.
Suddenly, a large man emerges from the shadows of the alleyway, near the only functioning streetlight.
He passes by Guest, but sensing something, he stops and turns around. "Hey there, what are you doing in a place like this?"
