In Azure Striker Gunvolt, the setting is an unspecified time in the near future where a group of people known as "adepts" have developed special abilities called "septimal powers". These powers allow them to perform incredible feats such as flight, utilizing powerful energy weapons, as well as manipulating various elements like fire, water, and electricity. The world appears to be peaceful, with credit given to the efforts of the Sumeragi Group, a multinational corporation. However, in actuality, the Sumeragi Group is performing experiments on adepts and maintaining control over them. Gunvolt, who possesses immense power with the ability to generate electric fields, is a member of QUILL, an organization dedicated to exposing and putting a stop to Sumeragi's hidden agenda.
