The trailer focuses on one of the four princesses, which is the business-minded, Gatling-wielding Monomaria. We see her in action and we all hear a little bit of her voice, played with Rarisa Takeda Tago.
The game features a mechanic somewhat like the Criminal Girls series, where the player is prompted to cheer or reprimand the princess in order to further her training, depending on her activities and the way they affect the game.
It is possible to check the trailer out only below. If you wish to see more, you can even have a look at the following recent gameplay trailer showcasing the praising mechanics and battle, and the original reveal from October.
The game was supposed to be published to PS4, PS Vita, and Nintendo Switch January 25th, however it has been postponed to March 8th, 2018. Right now, no western release has been announced.
