Ritsu pilots the Rose C'est La Vie of the Moon within the Hau Dragon's elite Hakkeshu unit. His most prominent feature is an extremely feminine facial appearance, deliberately engineered during his in vitro creation by scientist Masaki Kihara as an implanted psychological flaw. This trait fuels Ritsu's deep-seated inferiority complex and significant distress, leading him to constantly conceal his face behind a steel mask to avoid attention.

Within the Hakkeshu, Ritsu operates alongside Saiga (pilot of Omzack of the Thunder), Rokfel (pilot of Dinodilos of the Earth), and Giso (pilot of Burrstone of the Mountains). Group dynamics involve Giso's feelings for Rokfel and Rokfel's interest in Saiga, though Ritsu's specific relationships remain undefined. His mecha, Rose C'est La Vie, ranks among the Hau Dragon's most powerful units, rivaling Zeorymer. Its armaments include concealed chest and leg beam cannons, energy blades formed from combined finger beams (Moon Beam Swords), and the ultimate J-Kaiser weapon. The J-Kaiser requires orbital energy pods and generates blasts capable of creating massive craters and penetrating mountains.

Ritsu participates in the final battle against Zeorymer. During this engagement, the last three Hakkeshu mecha, including Rose C'est La Vie, sortie together, but internal bickering hampers the pilots. Masato Akitsu, piloting Zeorymer under Masaki Kihara's influence, confronts them and reveals the Hakkeshu pilots are clones derived from a single original zygote, representing fractured aspects of one personality. Immediately after this revelation, Zeorymer unleashes its devastating "Meiou" attack, simultaneously obliterating all three Hakkeshu mecha and killing Ritsu alongside Saiga and Rokfel.
