So, given the fact that this is a DxD story, obviously pairings will be made.
The pairings are somewhat up to whoever reads this, lol.
Obviously, Grayfia and other characters who are married won't count nor will the fallen angels that attacked issei and Asia because who would spare or love the people that basically killed your brother and a innocent girl lol, I never understood that in DxD fanfics.
Issei will be paired with Rias simply because I don't really know how to make her character work in a relationship, not because I dislike her or anything. Same with Irina.
I'm not too sure about sona or her peerage either, but if anyone gives me a good suggestion on how to go about it, I'll see.
Issei so far
1. Rias
2. Irina
3. Ravel
For y/n, just leave your pick for whoever you think is best
1.
2.
3.
4.
Also, for more info about y/n
His sacred gear is basically Fenrir sealed similar to the dragons, but Fenrir isn't exactly cooperative if yk his story, but with training y/n has learned to use most of the power on his own other than balance breaker.
So far, he can howl with powerful wind magic and has a sword with Fenrirs fang that can harm pretty much anyone.
He has increased strength, speed, and senses
He is able to use magic pretty easily since he has the son of a God in him.
He can use golden chains to hold enemies down similar to what was used on fenrir himself
He can summon twin spectral wolves to attack enemies as well.
He was trained by Azazel and got help from Odin. He's already met vali and his team, but he doesn't know about his plans to eventually leave and join the khaos brigade.
If I were to rank his power for the moment, I'd say he's around that level of power where he'll put up a good fight with Kokabiel.
With him being that strong, I'll have to work around him, not just washing everyone in season one, so events can still happen as they should.
