The trailer concentrates on one of those four princesses, that is the business-minded, Gatling-wielding Monomaria. We see her in action and now we hear a little of her voice, played by Rarisa Takeda Tago.
The game comes with a mechanic somewhat like the Criminal Girls series, where the player is motivated to cheer or reprimand the prince in order to further her training, depending on her actions and how they affect the game.
It is possible to check the trailer out just below. If you would like to see more, you can also have a look at the following recent gameplay preview showcasing the praising mechanics and battle, and the original reveal from October.
The game was designed to be released for PS4, PS Vita, and Nintendo Switch January 25th, but it has recently been delayed into March 8th, 2018. At the moment, no western launch has been declared.
