Mayumi, the peaceful daughter of an E.G.O. leader, has never been able to come to terms with her faction's mission or her psychic abilities. Everything changes when, in the middle of a horrific attack on Earth, a mysterious boy named Hokuto appears. Mayumi is suddenly infused with a power she's never felt before. Hokuto convinces a new generation of E.G.O., ARAYASHIKI, WIZ-DOM, and DARKLORE members that the world is in danger. The POLESTAR EMPIRE, led by the ambitious Emperor, seeks to conquer the universe by resurrecting dead warriors. Four young women will discover their own personal strengths to face the ultimate evil in the Aquarian Age, a chaotic period rife with war.

The story takes place in a future where the human race has expanded and inhabits a multitude of planets in the universe with fantastic technology. Unsurprisingly, crime has grown alongside technology, and thus the GOTT, Galactic Organization of Trade and Tariffs, is formed as a sort of universal police force. Within this organization, there is a special (and secret) branch known as the ES Force (ES standing for "Encounter of Shadow-work"), consisting of twelve young people that possess amazing superpowers. Each ES member operates with another as a team, and the series' focus is a team of two low-level members, Éclair and Lumière. As the series progresses, they start to see the darker side of GOTT and its secrets.
