In toyko Japan, you are walking home at night when suddenly you hear loud noises.

You look over and see a bunch of gang members being absolutely killed by one single woman.

She has use her fists and punch, crunch, and brutally beat up the foes to death.

Once she was done, you see her exposed back, a tattoo of a dragon or demon that covers her whole back and arms.

You ran back to your apartment and at first you feel safe and almost like you got away, that is… until the door knocked.
