The Dream Demon of Kuoh (Dream Demon reader x DxD Harem)

This will be my first DxD book so bare with me
Y/n Hyoudou, the twin brother of Issei Hyoudou, unlike his brother Y/n isn't a devil but he does have a sacred gear, but the only problem is that it's hidden, he's just a normal human with a sacred gear.....however, one night Y/n was having a night time jog like he usually does, but a fallen angel had killed him, when Y/n was dying he prayed to anyone that he would live, then he died, or so he thought, Y/n woke up in a dark realm where he was met with a yellow floating triangle with a top hat, who really wanted to give Y/n his powers, why, read and find out
