As mentioned earlier, Gust’s PlayStation Vita game Ciel no Surge takes place in real time. This communication game has players interact with Ion, a mysterious girl who lost her memory. Depending on when you turn on your system you may see Ion eating a meal or sleeping.
Ion’s hair grows as time passes and she gets more talkative too. Players can also change Ion’s clothes and customize her look.
One interesting note is Famitsu mentions Ciel no Surge supports online play, but details on how Gust’s game uses it have not been revealed.
