>>1606497>>1606487Let me try to summarize it. There was a war between humans, witches/wizards and succubus/incubus. A big percentage of people (mostly men) was decimated.
After the war ended and everything was resolved, there's still witches and succubus causing some trouble, so a special division of the police was created to deal with these.
Iris, Pandora, Chain (and later Fang) are part of this special police division. Iris is a gunslinger/sharpshooter, Pandora is a succubus, Chain is a witch and Fang is a fighter.
Of course there's ecchi/yuri involved, but I try to keep it a bit low, so I don't need to mark the project as "explicit +18" content.
