It has come to my attention an important issue: That this is not really a crossover story. Despite having Jiraiya in it, there will be no further influence other than the basics like summoning, which I may replace with familiars anyway, Rasengan, definitely not replacing, Sage Mode, and Kage Bunshin. Even then, these will be explained with magic and chakra mixed together.
Plus, Jiraiya is the only character that will be in the story frequently, the other two Sannin will be in the story, but infrequently except maybe in a character arc. Other ninjas will be referenced but not actually in the story.
His status will be as a human who has risen to the title of Lucifer level despite being human, making him one of the only people to do so, giving him the title of Jiraiya the Gallant or Jiraiya of the Sannin. Giving him the title as one of the only three humans to be able to stand against an ultimate class devil in his life.
He is also going to be as long lived as a devil due to his chakra and the sage nature of it, same as the other two.
So, I am keeping this story up and posting another version under the actual Highschool DxD archive.
I may still update this story as well as that one, but what I will do is make the updates to this one come a week after the one in the actual archive.
