Description
Ryuusei Date, an 18-year-old possessing exceptional psychic abilities classified as Psychodriver, was recruited into the Earth Federation Army. Following the death of his police officer father in the line of duty and his mother Yukiko Date's hospitalization for an unspecified illness, he entered the Burning PT National Tournament seeking prize money for her medical bills. After either winning or demonstrating impressive skill during an alien attack on the tournament, Major Ingram Plissken recruited him into the secretive SRX Development Project, with the military agreeing to cover his mother's hospital expenses as part of his enlistment.

Initially, Ryuusei displayed an extremely hot-blooded, impulsive personality and a deep obsession with mecha, particularly super robots. This mecha otaku nature led him to enthusiastically name and shout attacks during combat. He expressed disappointment that his assigned unit, the R-1, was classified as a real robot, though he later found satisfaction in the super robot classification of the combined SRX unit. His early military conduct involved recklessness, disregarding tactical orders, and a lack of respect for authority, straining relationships with teammates like Raidiese F. Branstein, who saw him as a liability.

Exposure to real combat fostered significant maturity. Ryuusei developed a strong sense of justice and an unwavering commitment to protecting lives, often prioritizing civilian rescue over mission parameters. This duty sometimes led him to question orders conflicting with his moral compass. He learned the value of teamwork, becoming a more disciplined and formidable pilot, rising to the rank of Second Lieutenant. The betrayal and defection of his mentor, Ingram Plissken, to the Aerogaters proved pivotal, prompting Ryuusei to seek answers and harden his resolve.

His childhood friend is Kusuha Mizuha, who initially held romantic feelings for him. Ryuusei did not reciprocate, possibly due to his preoccupation with mecha, and later supported her relationship with Brooklyn Luckfield. He formed significant bonds within the SRX Team, particularly with Aya Kobayashi and Rai. He is noted to be exceptionally close with Latune Subbota and Mai Kobayashi (Aya's sister), both of whom began emulating his otaku tendencies in attempts to gain his attention, though the romantic outcomes remain unclear. He occasionally expressed admiration for the aesthetic design of feminine-shaped mecha like the Valsione or Angelg, describing them as "cute" or "sexy."

After the defeat of the Aerogaters and Divine Crusaders, Ryuusei served as a test pilot for new prototypes like the R-Blade. He reunited with the SRX Team during the Neo Divine Crusaders revolt, piloting the SRX again. In the Alpha timeline, the SRX was destroyed by Balmarian forces and Aya was captured. During this period, Ryuusei piloted the R-Blade Custom until the completion of the Banpreios, the SRX's upgraded successor. He then spearheaded efforts to rescue Aya alongside Rai and Mai while combating threats like the Balmarians. He also participated in mock battles testing units like the R-Blade and Wildfalken.
