Known usually as a games publisher, DMM Games has just announced its first ever original project ever, Badminton Girls. The official site and Twitter page have just gone live.
We see five female silhouettes on the site, although we do not know their identities. As suggested by the clock shown the game is likely set in Sendai, Japan. There is little information for us to go on at this point in time, but it is safe to assume that we are looking at something related to the sport in question. An RPG or a simulator of some kind are the likeliest genres for this game.
The platform for Badminton Girls are not unknown either, although DMM plans to have the game go live sometime in Spring 2018. Be sure to check out the teaser site for further details.
