Oscar Storm used to be the shared pawn of both Rias Gremory and Sona Sitiri, but was neglected by everyone in the peerage. They always fond over Issei and Saji, even though their potential is near to nothing.
Rias and Sona always forced the work of both them and their peerages onto him, gave all of his hard work to both Issei and Saji & even punish him for the failures that these have committed.
Tried of being treated like absolute trash, Oscar request Sirzechs and Serafall to be removed from the peerages. After hearing his story and angry at their siblings poor leadership, they agreed.
Now a free devil, they recommend him to Malebolgia, the lord of the 8th Realm of the Underworld.
Once arriving, Malebolgia offers him to become his protege. Oscar wasted no time and accepted his offer.
After sometime has passed, Oscar becomes a powerful warrior in all of the 12 Realms. Alongside his peerage, which he gathered from many of the different Realms, are a force to be reckoned with.
But then, one day; Sirzechs, his Wife, his Son and Serafall came to the 8th Realm. Though happy to see them, the reunion was cut short by a situation: Riser has won the rating game against the combined peerages of Rias and Sona, meaning the two must marry him.
Although he voiced his distaste towards Rias and Sona, he agrees to it because he owes both the Gremory and the Sitiri families a debt.
But how'll things turn out against the former pawn and his ex peerages?
What if Issei never lived in kouh but lived in Kyoto instead? What if he wasn't even human But a Yokai Human hybrid? How would the Story unfold for Everyone involved in the Supernatural? How will this Affect the Relationship between the Yokai and the Three Factions? Will Rias be forced to marry Riser, and Asia Die at the Hands of Raynare and the Fallen Angels or Will a Japanese Half-breed Save them and be moved into the World of the Devils, Angels and Fallen angels, Along with the other gods only time will tell. One thing is for Sure things are never going to be the same for the young half-Yokai after this, But he is Damn well ready for what lies before him after his rough Past. Will the Woman he has loved since he was a child Return his love? Will he end up with more women falling for him and lusting after him? Only time will tell!
(AN: This is my First Fanfic, so sorry if it isn't the best out there, or if it has some Clich茅 and plot holes, I'll do my best to spot them and rewrite chapters to improve the Story. This Story will have a more experienced Issei, who is not just a crazy powerhouse for the sake of it but is Stronger off the rip than Cannon due to his Past. Also Any and All Sexualized content in this Story Involves Consenting adults that are over the age of 18!! Thanks to two of my Favorite creators on here for helping me Perfect the basic idea for the Story and form it into something that should hopefully work (@Helix_Asmodeus. and @DragongodAstaroth). Also, a Big thank you, @Skinny40k, for all the help with our discussions and the advice you gave!!)
