A 15-year-old, hardworking, boy with superhuman strength, speed, and martial arts training, that was summoned to Geminar from Earth. He is the younger half-brother of Tenchi Masaki. It is later revealed that he was hypnotised by Washu Hakubi prior to his journey, and exhibits characteristics of Ryo-Ohki when startled. He's an incredibly skilled swordsman (Mexiah claims that he's better than she is), master martial artist (capable of safely catching thrown knives in mid-flight), and is a one-boy army inside of a Seikijin cockpit. His Seikijin is unique in that it is white.
A vassal of Lashara's, Maya is sort of a cross between a nanny and a secretary for her. She offers sage-like advise to Lashara on various topics and helps her to stay on the topic at hand. Along with her two assistants, Angela and Vanessa, Maya is always there to take care of Lashara's more mundane everyday needs. Maya is the first to recognize Kenshi's potential and abilities.
Koro are two-tailed cabbits that usually serve as guards or messengers due to their ability to exchange information from long distances through their calls. Because of a pendant containing a piece of Ryo-Ohki's spaceship form, the Koro are attracted to Kenshi, the power of the pendant is revealed when the pendant is being examined by Ulyte and a large swarm of Koro appear at the window.
A thin, gangly woman working under Hannah, Jozzy is a worker division leader who is in charge of cleaning the students rooms. She has doubts about Kenshi's abilities when he's assigned to assist her, but quickly discovers the lightning fast speed in which he completes his tasks, and with the proficiency of a pro. The manner in which Kenshi impresses his superiors consequently makes Jozzy look good to the other department heads as Kenshi's boss.
A male seikishi that goes to the Holy Land Academy and one of Dagmyer's lieutenants. An intelligent man with rectangle glasses and a suave smile, he only follows Dagmyer to observe the end-results of his ambitions. Neil and his friend Alan abstain from joining the final battle between the Holy Land students and Ran's bandits, as they don't wish to fight against their own classmates. They surrender peacefully to the students after they witness Dagmyer's defeat.
Lithia's personal secretary and member of the student council. She becomes friends with Kenshi when he fetches a hankerchief that was her mother's from a cliff-face after it was placed there by older students who were being mean to her. Lapis also functions as something like a servant to Lithia, taking care of some of her basic needs, though this is most likely out of loyalty and not responsibility. Her sekijin is yellow with white patches of fur and a tail much like a lion's. Her sekjin's weapon is a halbard.
Recently elected Chancellor of the Shitoreiyu Empire, he practically takes over the government of Shitoreiyu in Lashara's absence. Father of Dagmyer and Ulyte's older brother, he seems to have no use for familial ties or emotions, and does not tolerate failure of any kind, even from his own son. His family have been craftsmen for generations, and therefore have information on the Senshi civilization, which also gives Babalun information on the general location of Gaia's shield, as well as the ability control anything created by the senshi civilization. Babalun uses the Babel fortress to take over the Holy Land and reactivate the Sekishin, Gaia. After discovering that Kenshi is the child of one of the mad-made seikishi made to destroy Gaia, he attempts to take control of Kenshi's body but he underestimates Kenshi's Jurian blood as well as his willpower. After failing to take control of Kenshi, he reactivates a fully restored Gaia, now equipped with Gaia's shield, and orders Doll to pilot it. When it appears that Kenshi is on Par with Gaia, Babalun takes matters into his own hands, and merges with the sekishin, which causes Gaia to transform into perfect Gaia, so he in effect becomes Gaia itself. After an intense battle with Kenshi, he is finally defeated when Kenshi's Tenchi rock sword turns to energy, shrinks and solidifies just for a moment into what looks like a Lighthawk sword, which cuts through Gaia's armor like butter. After losing his physical form, he attempts to take Ulyte's body to keep living, but Ulyte uses the device that he (as Reia) stole from the barrier workshop to delete all the data in Babalun's core crystal, which causes it to shatter, effectively killing Gaia for good. Dagmyer comes across a fragment of the core crystal later and cuts himself on it, causing the crystal to glow slightly. What this may mean is unknown for now.
