In a surprising turn of events, Koihime Enbu emerged from the shadows to celebrate its 10th anniversary and announce that the game will be getting a new version, featuring at the very least 4 additional characters, and hopefully, some proper network updates. Though that is largely just wishful thinking from the community and may or may not come true.
As a reminder, Koihime Enbu is a fighting game based on the long-running anime, manga, and adult visual novel franchise called Koihime Muso. The games are focused on China's The Three Kingdoms period, with the all the well-known male characters swapped to female fighters.
The fighting game itself doesn't have adult elements beyond some risqué outfits, and it's usually considered to be among some of the better fighting games of this scale.
