Anonymous; Code is a visual novel video game developed by Mages and Chiyomaru Studio, and is the sixth mainline entry in the Science Adventure series. Along with being a visual novel, it also has a fully working implementation of Conway’s Game of Life built in that can be accessed via the in-game menu. Following a series of delays, the game was released for PlayStation 4 and Nintendo Switch on July 28, 2022, in Japan. A Western English release, published by Spike Chunsoft, was announced in July 2022 with a Windows port, and released on September 8, 2023.



The game takes place in the year 2037, one year after the disastrous “Sad Morning” event which occurred on February 6, 2036. Due to date overflow errors caused by the Year 2036 Problem, a network of orbital laser satellites called SA4D (Strategic Attack For Defense) went out of control and attacked the capital cities of numerous countries around the world, causing significant chaos, destruction, and death.

Tokyo in particular suffered greatly, with the numerous satellite laser hits creating “Craters” all over the city. As a result, there are concerns that a similar disaster, the Year 2038 Problem, will occur. Meanwhile, technology has progressed significantly, with wearable computers called BMIs allowing people to seamlessly connect to the internet. Quantum computing has also become commonplace, with international laws put in place to prevent the creation of Earth Simulators.


However, that does not stop groups from researching them in secret. One such simulator is developed by child prodigy Asuma Soga at the Gai Institution, dubbed GAIA. GAIA can not only reconstruct or simulate events that happened in the past or present but can also predict future events, allowing whoever controls it to influence the future.

The story follows Pollon Takaoka, a young 16-year-old hacker who lost his father during Sad Morning. He makes a living taking jobs with his friends in the hacker circle Nakano Symphonies. He also comes into possession of a mysterious power he dubs “Save & Load”, which allows him to set “save points” in time and travel back to them by “loading” them like a game.


However, any saves made after the save he loads are deleted and lost, and saving the loads too far back in time puts too much strain on his brain, giving him an illness where he repeatedly goes comatose and is unable to stop tragic events from happening.

So he has to use his new power very carefully and avoid overusing it, but when used properly, he has miraculous abilities to predict the future and alter future events, something someone with an Earth Simulator can also do, putting him in competition with those who have access to Earth Simulators in trying to predict and influence future events.


Pollon initially just has Cross and Wind as friends to help him out, but gradually makes more friends and allies such as Tengen Ozutani (a private detective and former astronaut), Nonoka Hosho (a young girl and child prodigy who invents many gadgets), Liddie Kumar (a brilliant mathematician and online influencer), Rosario Rossellini (a Vatican assassin and skilled fighter who is fiercely loyal to Momo), and the Cyber Force Dolls (a trio of young police officers who solve cybercrimes and are also an idol group).
