Protagonists •
Tenchi Masaki is a teenager who accidentally releases the space pirate
Ryoko. His actions unintentionally cause the destruction of his school and the revelation that he is part-Juraian and a member of their royal family. In the 1st OVA it is revealed that he can create Light Hawk Wings (the power of the goddesses and Jurai ships) without the aid of a royal tree, and can also perform energy-matter conversion. •
Ryoko Hakubi is a creation of the scientist
Washu Hakubi (of her own egg and a substance called Masu), Ryoko was a space pirate in the service of Kagato until she was sealed in a cave for 700 years; she is released by Tenchi in the first episode. She draws most of her powers from three mysterious gems and is partnered with the
cabbit spaceship Ryo-Ohki. •
Ryo-Ohki, the title character, appears as a grey-colored cabbit (a cross between a cat and rabbit) and can transform into a spaceship. •
Ayeka Masaki Jurai, is a princess of the Juraian Royal Family. She is searching the galaxy for her half-brother and future betrothed Yosho with her sister Sasami when she detects Ryoko (whom Yosho had been pursuing prior to his disappearance) her tree-ship Ryu-Oh crashes on Earth, where she reluctantly joins Tenchi and Ryoko. •
Sasami Masaki Jurai is Ayeka's younger sister and a princess of the Juraian Royal Family. She stows away on Ayeka's ship prior to the search for Yosho. She has merged with the Goddess
Tsunami, which grants the Jurai family its royal trees. Sasami frequently cooks for the household. •
Mihoshi Kuramitsu, a member of the powerful Kuramitsu family of the Seniwa empire and a Detective of the Galaxy Police, is prone to clumsiness and can act ditzy, despite being highly intelligent. Mihoshi is distantly related to Washu, and through that lineage has the power of improbably good luck. She crashes on Earth while looking for Kagato. •
Washu Hakubi is a former Director of the Galaxy Academy and ranked as the top scientist in the universe. Washu's more recent pursuits involve investigating the three gems (the ones Ryoko were given) and creating lifeforms capable of harnessing their power (of which the Ryoko/Ryo-Ohki combination is one). She was trapped by Kagato and later released by Mihoshi. It is revealed in OVA 3 that Washu is a human manifestation of a sister-goddess to Tsunami and Tokimi. •
Noike Kamiki Jurai was raised in an orphanage and later joined the Galaxy Police. She was Mihoshi's partner and was adopted by Seto Kamiki Jurai, Ayeka and Sasami's grandmother, and is introduced as Tenchi's fiancée in OVA 3. The engagement, however, is a political pretense to allow her to monitor the powerful members of the household.
Villains and antagonists • Kagato is a former student of Washu (revealed in spin-off media as a creation of hers). In the pursuit of science, he frequently pillages ruins for relics with no regard to life or property, earning him the nickname 'Ruins Buster' and status of Eternally Wanted by the Galaxy Police. Kagato is the main antagonist of the 1st OVA making an attempt to recover Ryoko (whom he previously brainwashed into serving him) and use the power of her gems to capture Tsunami. • Doctor Clay, a former colleague and academic rival of Washu from the Galaxy Academy, is in service to Lady Tokimi in OVA 2 (in which he is the primary adversary) and is ordered by her to capture Washu and bring her to Tokimi. Clay uses the shape-shifting android
Zero to replace Ryoko and capture Washu. However he is outsmarted by Washu, captured and handed over to the Galaxy Police. • Tokimi is a mysterious hyperdimensional being (stated to be beyond all dimensional space) who is one of the "Choushin", the greatest "goddesses" in existence. Her sisters are
Tsunami and
Washu. Introduced in the second OVA series, where she orders
Dr. Clay to bring
Washu to her. Tokimi is not portrayed as an antagonist in the 3rd OVA, since she considers Tenchi as the result of their research to find a being even more powerful than herself, theorising that it might have created the Choushin themselves. While Tsunami and Washu were experimenting within the lower universes to try to discover an even higher level being, Tokimi was left in-charge of all
22-dimensional reality and controls it from the Hyper-dimension through higher-dimensional supervisors to conduct higher order chaos experiments. Though Tokimi's actions lead to trouble for Tenchi and his group, Tokimi turns out not to be a true villain as there was no malice in her actions but simply lacked the wisdom of her sisters. Tokimi now currently lives with the Tenchi family, as a smaller form, Toki-Chan. • Z (full name Z-0001332536893) is the principal antagonist of the third OVA series of
Tenchi Muyo! Ryo-Ohki. An anomalous being of great power, capable of punching holes through planets seemingly without effort. He is capable of creating Lighthawk Wings created through the experiments of Lady Tokimi. Throughout the 3rd OVA, he stalks Tenchi and his household, setting up a confrontation between Tenchi and Misao Kuramitsu and ultimately battling Tenchi to prove his superiority and disrupt the choushin plans. Z is portrayed as suffering from the loss of his family and resentful of the Goddesses and their meddling, despite serving Tokimi. • The is an anomalous being created as the sum total sentient "counter-force" from the Choushin Goddesses' sum total experimentation on 22-dimensional reality, and somehow merging with queen Misaki of Jurai. It is capable of causing their lower-dimensional shadows physical injury (visually appearing to corrupt their body, turning them black). Z found her in the future and used her in his plans to kill Tenchi and stop Tokimi's experiments. The counter-actor is stopped and healed by a kiss from the ascended future Tenchi and is revealed to be Masaki
Misaki Jurai (The 2nd Empress of Jurai and mother of Ayeka and Sasami) from some point in the future. :Background information released by the series creator indicates the Counter-Actor is from a point in the distant future (ten thousand years or more) when both her husband Azusa, and her co-wife Funaho have passed on, which caused Misaki to eventually go mad from her grief and destructive power. According to this information, during his time travel after being struck by Z's Light Hawk Wing, Tenchi was to encounter Misaki in her future time. Unfortunately, while planned, it was cut from the OVA.
