The trailer focuses on one of the four princesses, that is the business-minded, Gatling-wielding Monomaria. We see her in action and now we hear a little bit of her voice, performed with Rarisa Takeda Tago.
The game comes with a mechanic somewhat similar to the Criminal Girls series, where the player is motivated to cheer or reprimand the prince so as to further her training, depending on her actions and how they impact the game.
You can check the trailer out only below. If you would like to see more, you may even have a look at the following recent gameplay preview showcasing the praising mechanisms and battle, and the original show from October.
The game was supposed to be published to PS4, PS Vita, and Nintendo Switch January 25th, but it has recently been delayed into March 8th, 2018. Right now, no western release has been announced.
