[Western Fantasy + Male-Male Romance + Seven Deadly Sins + Everyone’s Favorite + No Pairing in the Main Story]
The world was made up of Heaven, the human realm, and Hell.
The angels of Heaven and the demons of Hell were sworn enemies. Whenever they met, they fought.
Vilder was a demon born in Hell.
He followed the Demon King’s orders to tempt humans in the mortal realm and gather their desires. Before long, he became a thorn in the side of both humans and angels.
Then disaster struck, and no one could stay out of it. This time, the dark beings everyone had always considered villains stood on the same side as them.
And those who had once despised and looked down on Vilder came to trust him with their lives after everything they went through.
“Until the world is destroyed, I’ll stand with you through everything.”
(The protagonist is beloved by everyone, with both friendship and romance. His moral compass as a demon is chaotic and evil. It’s a Western fantasy setting, but humans have developed technology.)
