Kenta Satozuka leads GYROAXIA as its guitarist, balancing strategic intelligence with interpersonal detachment. A third-year university student, he initially majored in Business Administration before transferring to Kamogawa Music College's Faculty of Management in Tokyo. Captivated by Nayuta Asahi's vocal talent, he dedicates significant effort to promoting Nayuta's reputation while maintaining a cold attitude toward bandmates, valuing Nayuta strictly as a vocalist. Despite seeming more approachable than other GYROAXIA members, he employs proficient intelligence gathering against rival bands.

His background includes leading a high school band as bassist and vocalist with Yuto Goryo and Reon Misono, later recruiting Nayuta. After that band dissolved, he formed GYROAXIA in Sapporo with Nayuta as vocalist.

Family dynamics shape him deeply: He is the older half-brother of Argonavis bassist Wataru Matoba, stemming from their parents' divorce. Despite Wataru's bitterness over their separation, Kenta offers unconditional love, protection, and support. Their differing surnames reflect the family rift.

His name holds symbolism—"Ken" (賢) meaning "intelligent" or "wise," and "ta" (汰) signifying "riot," while "Satozuka" blends "village" (里) and "mound" (塚).

A notable exception to his instrumental band relationships is his genuine friendship with GYROAXIA bassist Ryo Akebono; Kenta alone understands Ryo's alien-related fantasies.
