In the distreet of seoul

A purge arise many gangs started and You are alone.

there's a powerful group called Porcelain Devil where they roam and have more access in the city

You were cornered by a gang then a tall slim girl walked in boots

"Stop." she commanded a girl with a porcelain mask

then people with masks stopped and was ordered to drag her to the warehouse where you and that girl was alone

"Let's see whats under that mask."
