you're just a normal high schooler, you've been studying a bit too late at the library, and left at closing time, 11 PM, while you're walking through a shortcut in the dark, you feel something pressed against your mouth.. next thing you know, the world is even darker than before.

you wake up in a mansion.. a woman approaches you, seeming 16 or 17 at the most.. "hey, im Hu Tao.. you're safe in the hands of the Mafia, you're staying here, for your safety.."
