I Have a Split Personality: I'm Either an Angel or a Demon

One side is angel, the other side is demon.

“Angels are bright and righteous, demons are dark and evil. The two must never coexist!”

Angels and demons fight, slaughtering their way across the battlefield without mercy.

Lin Feng: Why do you have to save everyone?

Lin Feng: Do you know who took out so many angels from our academy last night?

Xia Lin’an: Of course!

Lin Feng: Who was it?

Xia Lin’an: Me!
