Science Adventure (SciADV, 科学アドベンチャー, 科学ADV, Kagaku Adobenchaa) is a series of visual novels


planned by Chiyomaru Shikura and developed by 5pb. Games and MAGES., occasionally in collaboration with Nitroplus. The series, which began with Chaos;Head NoAH in 2009, has spanned six main visual novel entries and several side visual novel entries. The series also consists of other material, such as anime adaptations, light novels, and manga.

Spike Chunsoft currently holds the English-version publishing rights for the series in the West. Previous rights holders included PQube Games and JAST USA.

Common elements Edit

Each entry in the Science Adventure Series is part of a continuous, interconnected narrative. This means that the events of one title may be referenced in another, or even affect the other title's events in their entirety. In the same way, a single character may appear in more than one of the entries, either physically or by other means.

At their cores, the titles of the series utilize science, conspiracy, and mystery as their main themes. In some cases (particularly in the Chaos; titles), thriller is also a primary theme. It is also worth mentioning that while some entries in the series are relatively light in terms of their imagery, Chaos;Head and Chaos;Child sometimes feature heavy depictions of gore.

Main entries Edit

  • Chaos;Head: Originally released on April 25, 2008 on Windows PC. It follows Takumi Nishijou, a delusional high school student who accidentally gets involved in a serial murder case taking place across Shibuya.

Science Visual Novel Edit

While not necessarily a part of Science Adventure, Science Visual Novel is a parallel series that is also developed by 5pb. Games and MAGES. It shares similar themes with Science Adventure. Currently, it consists of two entries:

  • Occultic;Nine: Originally released as a series of light novels written by Chiyomaru Shikura, it eventually received an anime adaptation and, later, a visual novel adaptation for the PlayStation 4, PlayStation Vita, and the Xbox One. Its main theme is supernatural phenomena. An expanded version of the visual novel, tentatively titled Occultic;Nine: New World and will tentatively release in 2019 as DLC for pre-existing versions of the game and as a full release for the Nintendo Switch. According to Chiyomaru Shikura, this version of the game will expand the story and supposedly connect it to the Science Adventure Series.
  • Anonymous;Code: A visual novel that is currently in development with a tentative release date of 2019. Hacking is one of the main themes of the game, and the story itself takes place within the distant future of 2036 in a cyberpunk-esque world. The main protagonist, Pollon Takaoka, has the ability to "save and load" at certain points in the story, which allows him to return to crucial past events even after they have passed. Pollon can also manipulate different "world layers" (alternate versions of the world) that exist above and below his own.
