Powers & Techniques
Sechs is a genius; said to be as strong as an army of Mages. He specializes in Gravity magic, being the first Mage to ever master it. He can use it to fly and has acute enough control to use it to supress Acht's Union symptoms. Sechs also has an insane amount of magical power, which is needed to use his Gravity magic.
As a Union, Sechs possesses the Drive Deadly Sign, which allows him to turn other people into Unions. However, sometimes the process will fail, resulting in a Gainart explosion.
Sechs wields the Sword of Destruction: Kusanagi. Sechs controls it with Gravity magic to fire the blades at high speeds. The Kusanagi also lets him negate Phenomenon Interventions and grow stronger every time the world resets. By the time of the Es Route, Sechs is by far the strongest character in the XBlaze series, being able to easily kill four Es-N units at once as well as defeat Kuon, Mei and Es. Even Touya with the power of Awakening Release (XBlaze) can only barely defend against him for a while.

XBlaze Lost: Memories TIPS Entry
The 6th Ten Sage. He uses magic that controls gravity. Sechs comes across as distant and somewhat cold. Even his closest companions often have no idea what he's thinking or feeling. The only mage to truly understand the concept of gravity, he applies what he learned to his magic and became the youngest Ten Sage at the age of eighteen. He is considered a genius. Due to the difficulty and the sheer amount of raw magical power required to manipulate it, Sechs is believed to be the only mage capable of using gravity in his spells. During the Embryo incident, his crystal was shattered by Touya Kagari after his powers manifested and was cast into the Boundary along with the Kusanagi. It is believed that his soul, bound to the Kusanagi roams the infinite expanse of the Boundary.
