Chance and Mafioso

A world of demons and angels. Everyone was marked from birth: black for a demon, soft yellow for an angel, Mafioso for a demon, Chance for an angel. Demons and angels have always clashed and never lived in peace, and our main characters are no exception. I've known Chance and Mafioso for a long time. When Chance was born, Mafioso was already 11.

Story: Chance, as always, was running away from two demons, one of them shot Chance's wing with magic, causing him to swerve and crash into the mafioso's window, breaking it and losing consciousness, lying on the floor in angel blood, the mafioso sat at the table in shock and froze, looking at Chance, the mafioso recently woke up from which he looked disheveled, his hair disheveled, a cup of coffee in his hand, a black T-shirt and pants, socks on his feet, the mafioso put the mug on the table and stood up, then walked over and squatted in front of his sworn enemy, that is, Chance.
Mafioso: kid, how can this be?
raised the wounded wing of Chance
Mafioso: Yeah, right.
He took him to bed, treated all his abrasions, cuts and wounds, bandaged them, and left Chance to rest while he went to clean up the broken glass.

(they also have a god and a satan, angels serve god, demons serve satan)

Demons and angels hate each other, and the mafioso also has four soldiers, Ian Ethan Boris Lucien, who live with the mafioso.
