Galaxy Police. She met Seina when he was first taken from Earth to the GP Academy, and was taken by Seina's hair, which she constantly pets. Since then, Mitoto would be occasionally popping into Seina’s life from time-to-time, often helping him out during certain events in the boy’s life. (Toonami version; the redub was necessary due to Seiryo's original English voice sounding too effeminate). After his humiliating "defeat" by Tenchi Masaki, Seiryō developed a personal hatred for all Earthlings, a grudge which would continue on into Tenchi Muyō! GXP. He holds a teacher's position at the Galaxy Police Academy, and immediately develops a distaste for the human Seina Yamada when he becomes a cadet. Seina becomes Seiryō's unwitting nemesis, constantly foiling his endless idiotic plots for revenge (mostly through Seina's streak of bad luck). Having rebounded from his missed shot at Ayeka, Seiryō becomes infatuated again by childhood acquaintance Amane, despite being frequently and violently rejected; her attachment to Seina only serves to deepen his hatred for the young recruit, so much so that in Episode 6, Seiryō deliberately holds up the necessary body augmentation that Seina needed to at least survive life at the academy. However, Mikami Kuramitsu found out and punished Seriyō by assigning him to clean toilets... with her niece Mitoto supervising. Seiryō is brash and overconfident, often severely embarrassing himself through acts of sheer incompetence. However, he is also an accomplished fighter, and is quite proficient with a lightsword.

("Otokui Kami-Sama wa" ("御得大神は"))) and becomes the captain of the Daluma guild's new anti-Seina Good Luck Fleet, constructing the Fleet's flagship, Seiryo becomes the captain of the Daluma guild's anti-Seina Good Luck Fleet's flagship; in a stunning display of idiocy, Seriyō names his flagship "Unko" after all the other ships in the Daluma guild's anti-Seina Good Luck Fleet's flagship had taken many of the "perfect good luck names". (運呼, "Unko" which could mean "Luck Bringer" in Japanese... is also translated as うんこ, lit. "poop", a childish word for "excrement", when spoken aloud). After fighting the G.P. ship Kamidake II to
