It will be about DxD and Vrains. My idea is having 12 lost incident victims instead of 6 and the AI created from them will be turned into the twelve zodiac. Also the OC will replace Issei as the Protagonist. I don't hate Issei he is a good character but I do not know how to put him in the story so that's why. The twelve zodiac AI will also have special powers that only they can use. The zodiac AI cannot use these abilities well unless they have fused with an individual of their choosing. The chosen individual has the control not the AI. I'm getting this idea from Star Force. Any way here are the Zodiac AI and their specialties.

Taurus-Neutral

Leo-Light

Scorpio-Poison

Aquarius-Water

Sagittarius-Nature

Gemini-Thunder

Cancer-Dark

Aries-Nuclear

Pisces-Mental

Capricorn-Earth

Virgo-Wind

Libra-Fire
