An Angel Is a Demon? What Nonsense!

[Urban supernatural, demons, no harem, no System, not invincible, not brainless, with a romance and people who like the protagonist but won’t end up with them]

They say... everything comes at a price.

Become a demon’s Host and gain power? Would you choose to wield the demon’s power and run wild in the world, or become a guardian until the demon completely takes over your body?

Then what is my price?

“O sole angel walking among mortals, please tell me, tell me the truth about you. Are you... an angel who will save the world, or...?”

“I am the Morning Star. I am Lu Xifan. I am the pride that will save the world... Close your eyes. I will save every one of you.”

“Who... are you, really?”

“Lucifer.”
