บท 24: Bleach x DxD 4

So, I was thinking of what next to request on here when I found an old fan fiction that had a pretty interesting idea going. Unfortunately it only reached three chapters before being abandoned. Sadly, the idea doesn't really have a simple way to describe it, so I'll just list it out the way that I see it happening. I want Ichigo to be a mysterious character, and not necessarily the main character in the traditional sense. Rather, I want him to be a sort of support character that slowly goes more into the spotlight as the story progresses. I also want him to be the guardian for a less perverted Issei that was brought up by him. In other words, I want Issei to be an orphan that was adopted by Ichigo, and therefore he does not ever grow to become perverted in nature due to that. Other than that, I do want Ichigo to be post TYBW arc, with all of his powers, though all of that can be revealed later in the story. I want Issei to never become a devil and instead refuse to be a member of Rias's peerage. Of course, Rias will have to directly request this of him rather than him being in the middle of dying, as Issei will already be fairly strong by the time that Raynare comes to steal his sacred gear, and will be able to successfully hold her off. I want other Bleach characters to make appearances as support characters too, though you can give them some spotlight every now and then depending to the situation. The most notable ones I want to be involved are Kisuke and Tessai, but others such as Chad, Uryu, Orihime, or any shinigami would work fine. Have Issei be aware of Ichigo's strength, and train with him all the time, but do not let Issei know about Ichigo's past or his true origins until later in the story. Have Ichigo have notable connections with all of the different factions, but to them Ichigo disappeared off the face of the Earth several years ago, having last been seen a couple years before he adopts Issei. I got this idea from a fan fiction on fanfiction.net called "Our Lovely Song of Death" by Tek-Knight, if you're interested in reading the three chapters the story has. It's not very long, but the idea is nice, so I figured I'd give credit to where it's due.
