This is a Lucifer and mc as yuu' parents, Luke as ortho, and a mammon as idia story I just thought of it During mine photo shop class And I thought why not soooooo.... After a tragic accident both mammon's and Luke's live were lost leaving the other hart broken. But they must MoveOn. Mc and Lucifer end up getting married and has a child together, a beautiful, baby boy, who they named yuu and when the yuu was old enough, they were excepted. And to MC's father's school called nightravencollege where yuu's grandfather was the headmaster yuu ends up getting placed into ignihyde the room where he meets Shroud siblings idia Shroud and ortho Shroud and something immediately connects the three of them, some sort of familial bond, a bond that makes them separable, what would happen when the Shroud siblings meet yuu's parents and uncles and someone a certain white haired demon once called his lover?
