This is the true form of the second son of the shogun family, after he was rescued by Tallgeese's Charge Piercing Slash from the Blaster Gundam that had been absorbed by Gundam Yamigensui. While his older brother, Buiou, is likened to the light of the sun, he fights using the power of the moon's light. Because he was raised as a Blaster, he cannot simply join the Gundam Army, but he fights against the Yamigensui for the sake of his bond with his friend, Tallgeese. He fights with the Star Sword Ginga, whose blade shines mystically like a star, but the style of the sword is not Kogikenjutsu Yokushin-Touryuu but Rakuen Shinpuu-ryu. By attaching the Moonlight Wing to the Moonlight Cannon, it becomes the Moonlight Bakusei Cannon, and he is able to fire the Heavenly Secret Technique, Moonlight Bakumetsuha.
