Sumeragi Group

The Sumeragi Group is a enormous conglomerate that controls the power companies, the media, space development, and military technology of a specific small Far East Asian island nation making them it's de facto ruler. They are also responsible for producing all of the nation’s research on adepts, and are at the forefront of all research on both the Septimal (7th) wave of the Lifewave and adepts. They serve as the main antagonists group in the video game Azure Striker Gunvolt.

History
Ever since the Heian period (794-1185), Sumeragi has been involved with people who possess supernatural abilities, like the mystics and shamans attached to the Tetrad (4th) and Quinary (5th) waves of the Lifewave who were quite prevalent during that era.

In Azure Striker Gunvolt
At some point before the events of the game, Sumeragi created an artificial adept named Joule. Using her septima, which manifested itself into a girl known as Lumen, Sumeragi used her songs to help them track down adepts in a plan known as "Project Muse", a venture led by Lieutenant Nova Tsukuyomi. However, eventually Joule is freed by QUILL agent Gunvolt, prompting Sumeragi to begin looking for her.

Eventually, Sumeragi manages to track down the muse and recapture her, allowing Project Muse to continue. Unfortunately, Gunvolt heads to the orbital station Firmament and once again frees her, resulting in the deaths of several high-ranking officers, including Nova, and the failure of Project Muse, sending the Sumeragi Group into a chaotic state.

In Azure Striker Gunvolt 2
Despite the failure of Project Muse and the deaths of Nova and his adepts, Sumeragi is still shown to be exists in Azure Striker Gunvolt 2, though their spot as the main antagonists has been replaced by a group known as Eden. Exactly how big a role Sumeragi plays in the game is currently unknown.
