This auxiliary chapter is to inform some changes that I am considering making.
1. The Naberius family accident arc is kind of dragged out by what I reanalyzed. I'm thinking of rewriting or changing the parts, I'll keep the same idea of the fugue. But maybe reduce the change of view for the same situation. (This is a more optional change if I have the time)
2. I'm considering changing some of the powers, yes I established early on that he had Shadows and a little bit of Darkness. I'm thinking about keeping or removing the Shadows. His bloodline powers would be relative to the parents, the Light power of the Lucifers and the soul power of the Satanachia (as I established). I can keep the shadows as a spell he uses for now because he doesn't know how to use his innate nature, I'd just have to change the beginning a little to explain how he learned it. I'm leaning towards keeping the devil's power to use the human system of magic, but I'll stick with the decision to take away Darkness magic's affinity.
3. I'll change the beginning to explain how Grayfia got the information where the boy lived to take care of him temporarily. It doesn't make sense the way I wrote it because technically Rizevim's location is unknown, but it's within the territories of the Old Devil Kings Faction.
4. Finally, not exactly a change, but here's a preview of what I'm going to put in the protagonist:
• Base Powers(no outside influence) :
— Demonic Brilliance of Evil Light (Lucifer bloodline, by the way official DxD but never explored.)
— Underworld Waves (Satanachia bloodline, based on Saint Seiya's Cancer Manigold's soul power)
— Shadow Magic (Using the human system, soon she will be very weak until he gets a suitable mage to teach him)
5. Whether he will use external means to build more power? Of course, as a wise man would say, if it's in the game, it's for use.
— Sacred Gear? No! Why not? He will have something similar created by devils. A form of equipment equivalent to the antithesis of sacred gears.
— Power amplifiers that damage the body? Yes! Which? Ophis' serpent and the King Piece.
— Any weapons? Yes! He will obtain the weapon created by the Babylonian gods, the divine chains Enkidu. Just chains? I considered a sword, but since he's going to have multiple powers I think a chain that reduces the divinity of certain opponents would be more suitable. (Ps. If it's still not clear, the chains are inspired by Gilgamesh's Noble Phantasm from Fate)
— Anything else? Yes, a technique created by Grigori and a certain experiment that can amplify the Lucifer lineage's affinity with the light or holy element. In addition, he will also have two other itens relating to the seventy-two pillars of the underworld.
6. Will the character be overpowered inside the DxD in the future? Yes, that's the goal, he will have to face the Machine Gods of ExE in the future and against another being created for history. But, I intend for him to gradually develop his powers, and I want him to have defeats along the way, including planning that one of his defeats involves him trying to recruit a member of the peerage.
7. As for peerage, I already have some ideas, but later I create a specific auxiliary chapter for suggestions.
