NISA is preparing for the upcoming launch and the game is coming to North America in limited quantities carrying an M-rating.
Why an M-rating? the ESRB writes:
“A variety of scenes depict a supernatural villain who harasses female characters and makes sexually suggestive comments (e.g., “Come, come and sit on daddy’s lap. We’ll have fun exploring each other,” “You can be a cunning linguist, my dear,” “I’m dying to leer at her longingly,” and “Mmmm, the height of ecstasy, licking a nubile maiden’s wounds!”/“No, hey stop . . . I said stop it!”)—accompanying licking sounds can be hea”rd off screen.”
If the suggestive nature of the game hasn’t turned you off, you can check out an interview with NISA hosted by Siliconera: here.
