Stand Up The Red Dragon Emperor (CV x DXD crossover)

Ground rules
This is my first thread and thought of multiple ideas in my head and this was the idea I decided on. This is obviously an AU given how DxD and Cray shenanigans won't necessarily interact with each other well. Furthermore, this will take place in the G era as V has way too high values for power and I don't play overdress. That said, certain characters already have their decks chosen in advance, and some v decks who will adapted into a G format, but there is a poll regarding Asia, genuinely unsure of how to mold her character in this thread. That said I will post the characters who have will be prominently displayed as well as their decks.

Issei Hyoudou (obviously the MC): Kagero (Overlords)
Xenovia Quarta: Aqua Force (Valeos)
Valerie Tepes: Dark Irregulars (Schrahot)
Latia Astaroth: Megacolony (Gredora)
Daigo Olivier (an OC/DxD equivalent of Gaillard): Royal Paladin (Sanctuary Guard)

Hope this goes well and I should have a chapter up after a few weeks. Sorry in advance for poor writing and short chapter sizes given the time period involved.
