Liberation Maiden must have been a huge success on 3DS and iOS, because Grasshopper Manufacture and publisher 5pb are now working on a PS3 visual novel adapted from the handheld adventure game. Ladies and gentlement, behold: Liberation Maiden SIN.
If you're unfamiliar with the premise of Liberation Maiden, the game is basically about Japan's teenage president Shouko Ozora, who arms herself with a giant mech suit in order to save her country. Liberation Maiden SIN stars Kaido Kiyoto, her Chief Aid.
Kaido happens to be a mind reader (Because WHY NOT?), and works closely with President Shouko and her cabinet of fellow teenage girls. Just to make this setup less creepy (but no less weird), Kaido also appears to be a teenager.
While the game hasn't been advertised as a dating sim, Famitsu mentions “many new beautiful women” (using the term "women" loosely) keeping Kaido busy. Suda51 also wrote some of the game's scenarios, apparently.
Beyond all that, we don't know much about Liberation Maiden SIN, not even when it'll be released.
