Koei Tecmo announced Toukiden: Mononofu also known as Toukiden: Slayer for iOS and Android at Tokyo Games Show 2016. According to the official announcement, the game will be playable in 2017 and the pre-registration for the game is available now.
Basically, Toukiden: Mononofu is a game like Monster Hunter but the difference is that players must fight against demons to obtain necessary materials to upgrade gears. In the game, players stand in a territory where a war between demons and humans have happened 8 years ago. Everything is back to normal, but that territory is still a war zone surrounded by Onis, and it will be your duty to hunt them.
For the moment, the game is about 85% complete. Hope it will be released soon. Head to the official page for pre-registartion.
