And in other Kerisgame-related news, we're introducing a new hack! This one is a fluff hack revolving around akuma - we're repurposing the word to mean metaphysically inhuman things, which are usually but not always the children of Second Circle demons and up. The Four Winds are among the most powerful akuma in Hell. The children of Third and Second Circles are less powerful, but still akuma. That means that as a term, "akuma" means "being native to a Primordial Mythos" or something that's been artificially made such to the point that they no longer have a human soul structure. They are permanently Outside of Fate and Inside (Primordial) Mythos, and a normal being turned into an akuma metaphysically dies for the PoV of things like Exaltations.
That in turn means that means that DB akuma are fucking scary because they're playing in that sort of ballpark - and are also each metaphysically unique. It's not dissimilar, in their case, to oWoD Void Adaptation - they're no longer human, and have been turned into a spirit thing with powers themed around their old abilities (so they can still pretend to be a Dragonblooded or whatever), but which will have potent and dangerous new Panoply abilities as an upgrade.
The reason I mention this is because after a certain point, Infernals start having akuma children. Aiko, the little girl growing inside Sasi? Both her parents are quite powerful Infernals, and her mother has a Mythos Charm and her own soul-world. She's a little devil child; dark-skinned - not dark like a human, but dark like the night - and she can wear many faces. The fires of Malfeas burn in her bright green eyes and drip from her fingers when she wills it. When she dons her dragon form, brassy feathers are revealed, maned over her dark flesh - and in that form she breathes fire.
