My Life Is so Hard as a Succubus

Demons and angels are originally opposing parties. In the war that lasted for hundreds of years, the two sides have been fighting for divine power and the dominance of the human world. One day, the Demon King of Lust, one of the seven most powerful demons, had a terrifying idea. Using the angel's flesh and blood to combine with her blood, a twisted thing was born that should not have appeared. The child "Eiger" who was born into this world without anyone's expectations, has the pure appearance of an angel, the cunning evil charm of a devil, the wings connected by black and white gradients, and the terrifying hidden strength is waiting to be unleashed. What awaits him in the future is the evolution of the devil's blackening, or the holy angel's purification. This novel and its characters are purely fictitious.
