From the creator of Senran Kagura as well, so you can expect a few certain things.
UK Publisher PQube announced today that Valkyrie Drive: Bhikkuni is indeed heading to North America and Europe exclusively for the Vita this year.
Valkyrie Drive: Bhikkuni is a game from the same director of Senran Kagura, Kenichiro Takaki. The series revolves around pairs of girls fighting, but the girls can turn into weapons through kissing each other. This is possible because of a virus that separates them into two classes: Extars and Liberators. Extars "...transform into high powered weapons when sexually aroused." Liberators, on the other hand, wield those weapons. And because of the nature of the game, there will be clothes stripping similar to that in Senran Kagura.
More gameplay features include taking on large waves of enemies, aerial combat, leveling up weapons, dressing room shenanigans/touching similar to Senran Kagura, 7 playable characters, 28 story missions, and even an arena-like multiplayer between 4 players. There is no word on any different modes, however.
Because of how over-the-top Valkyrie Drive was compared to Senran Kagura, it was only released in Japan -- though Kenichiro definitely wanted to release it in English.
Naturally, this changed just now.
Nichegamer also reported that the publisher will not censor the game on Twitter, unlike how it was done in Tokyo Mirage Sessions:
Valkyrie Drive: Bhikkuni is set for a English release on the PlayStation Vita both digitally and physically in 2016; no exact date has been given just yet. Nor is there any word on a collector's edition. There is also an anime called Valkyrie Drive: Mermaid if fans wish to know more about the world of this game.
