Ritsu

葎

Ritsu, the masked man, is the fourth Hau Dragon robot pilot dispatched to destroy Zeorymer.
He wears a mask because he was born with a woman's face. As a result, his teammates berate him, compelling him to keep the mask on.
Ritsu's robot, "Rose C'est La Vie of the Moon", is arguably the second most powerful of the eight robots created by Masaki Kihara, with Zeorymer being the first. It is heavily armed, featuring multiple beam cannons, lasers that can be focused into blades at the tips of the robot's fingers, and finally the J-Kaiser, a massive energy cannon.
Ritsu is also the only pilot to fight Zeorymer when Miku Himuro is not present inside the robot. This significantly reduces Zeorymer's chances against the behemoth.
However, despite all these advantages, Miku eventually merges with Zeorymer, activating the Dimensional Coupler System. Zeorymer unleashes its Meioh attack, destroying Rose C'est La Vie along with Ritsu.
