It appears that we may be getting the second game in the Utawarerumono trilogy, if this rating by the ESRB is anything to go by. This listing lists the title, under the name Utawarerumono: Masks of Deception, as coming exclusively to the PS Vita in North America and releasing with an M rating for various content descripters including blood, language and partial nudity. The publisher is listed as SEGA, however no formal announcement has been made yet from SEGA or Atlus USA, the publisher of the recently localised Aquaplus games.
Here is the description of the listing.
This is a strategy role-playing game in which players help an amnesiac hero regain his lost memories. From a 3/4-overhead perspective, players explore the environment, interact with characters, and engage in turn-based battles against enemy soldiers. Players use swords, staffs, and magic spells to attack enemies; damage is indicated by flashes of light and hit-point numbers. A handful of sequences depict large bloodstains on the ground and splashes of blood as a character slashes through an army of enemy soldiers; large blood stains may also appear on the players’ screen. The game contains references to sexual material in the dialogue (e.g., “We would like you to describe Master’s habits. His sexual likes and dislikes. . .The average number of times Master is able to perform on a nightly basis. Also his favored positions” and “It’d be a shame if those great t*ts of yours never get the lovin’ they deserve.”). Some sequences and gallery images depict characters partially nude with obscured breasts and buttocks; one prolonged sequence involves a character losing her underwear/bottom and exposing her groin— though no genitalia is depicted. The words “f**k” and “sh*t” appear in dialogue.
Utawarerumono: Itsuwari no Kamen released in Japan back in 2015 for PS4, PS3 and PS Vita, with the third game Futari no Hakouro releasing last year in Japan for the same platforms. The original Utawarerumono visual novel originally released back in 2001 for PC as an adult title, before receiving all-ages PS2 and PSP ports later in the decade exclusively in Japan.
