Sony after the Android version today on July 4, 2016 released the iOS version of the Shinkukan Doll smartphone game. The game available in the Japan AppStore as a free to play title. The Android version available a long time ago, from April 26, 2016.
This game plays in a fantasy world where the gravity is not working as we used to in the real life. You are playing with a special doll character in an anti gravity town and you have to help this robot like doll to customize herself. Of course you have to clear several missions to do it.
Despite the game already available you can pre-register until July 8, 2016 (18:00 local Japan time) and if you do it, you can start the game with 250 gift legacy chips.
