Abyssal Dision

In 2018, Dision finished his academy in Sandbury Defense College, organized by General Resource Ltd. He graduated with a degree in Aerospace Engineering. Then he joined up with General Resource Defense Force on September soon after his graduation. During his time with GRDF, he was designated as Ace pilot after successfully carrying out missions he was assigned to in outstanding result, including his service of suppressing terrorist operation in 2026.

In year 2030, it was believed that Dision was in GR's experimental research, known as 'DOE', a military project led by a woman that he loved, Yoko Inoue. Dision and Yoko were experimenting with transferring personalities onto the electrosphere when an unknown military group decided to bomb the research lab, just after Dision's personality was downloaded onto the electrosphere. It seems as if the AI Dision does not recognize himself and seems heartbroken that she is with another man. Utterly failing at warning them, the bomb explodes destroying the lab, and killing Yoko and the real Dision. AI Dision is completely helpless to do anything but watch the burning wreckage from a security camera in the distance.

In the same year, Dision was recognized that he met a 9-year-old girl that possessed fascinate ability in piloting, especially using COFFIN system. Later, he invited this girl, known as Rena Hirose, to participate GR's power development project, before she joined UPEO 7 years later, in 2037.

Dision was a military partner of Keith Bryan, who graduated from the same college in Sandbury Desert. During the war, they were seen to have some flight and combat trainings with UPEO's pilots. But later on, he defected from GRDF and was found out that he was the primary leader of a terrorist organization, called Ouroboros. He was alleged that he had led the organization for a long time, and later he was revealed he was an 'Artificial Intelligent' program that had the ability to hack another AI program that flew aircraft through COFFIN system. His presence as AI programmed pilot was the result of sublimation
