Karura was once princess of Na-Tunku before she was taken down and replaced with a puppet of the Shakukoporu. She is found after killing many enemy soldiers *with her bare hands* in order to escape. Even though she's royalty, she decides to live a "normal" life as "Karura", serving Hakuoro. She and her brother are the last two Giriyaginas on Earth. Her superhuman strength lets her wield a ridiculously heavy sword, thus making her a very effective shock troop, acting more like Hakuoro's tank on the battlefield and ripping through enemy troops. She's often seen carrying a jug of sake around, sometimes even on the battlefield. She appears to have known Urutori from long ago, though their shared history is never revealed. During the slave's revolt in Na-Tunku, Karura swears everlasting devotion and fealty to Hakuoro, the most sacred vow one of her kind can make. Her brother, Derihourai, becomes the new emperor of Karurauatsuurei (named after Karura), the new name she gives Na-Tunku after the slave's revolt succeeds.
The Director General of Space Patrol's Ogikubo branch. He has a strong sense of justice, to the point that his many catchphrases include the word "Justice." Although he talks big, he acts little, often relying on other characters, especially his secretary. He also jumps to conclusions, as seen when he repeatedly arrests and frees Luluco in the first episode.
He is almost always seen sitting at his desk and gesturing with his extended index and middle fingers in the shape of a gun. His skeletal body constantly burns with a purple flame, which appears to be a manifestation of his sense of justice.
Jean Henri Fabre first appears in the beginning of the first episode, when he attempts to steal the "Immortal Beloved." He rides a giant mechanical grasshopper and can control bees and other insects to use as weapons. Like the insects he studied, juvenile Fabres are shown moulting from one form to another, growing from child to adult in a few days. Two Fabres are shown in the series; the first Fabre apparently dies by crashing into a Tokyo office building, but actually moulted and escaped, taking the form of a child until he fights and is killed by Drake Anderson within the I-Jin base.
Toboe is the youngest of the group often acting more like a puppy. Toboe was raised by an elderly woman as a pet. She gave Toboe his silver bracelets. Although she died, Toboe has an affection for humans that none of the other wolves can understand (with the exception of Blue). Toboe looks up to Tsume and usually follows him when the group splits up. He also seems to have the best hearing out of all of them. Toboe seems to be a Red wolf in the series. (Source: Wikipedia) Toboe's name means "Howling" in Japanese.
A wolfdog who was pet to the family of Quent Yaiden. After the destruction of her home, Kyrios (Curious), and most of her family, she travels with Quent hunting wolves. She lives her life as a pet dog, unaware of her wolf bloodlines. Upon meeting Cheza, the wolf in her is awakened. Unable to continue hunting her own kind, she leaves Quent to travel with the pack to Paradise. She grows especially close to Hige. Blue has black fur and blue eyes, looks, in addition to most likely based after a Grey Wolf, to be either part German Shepherd or part Siberian Husky (this is the most probable due to her eyes).

A police detective and ex-husband of Cher Degre. He is still very much in love with Cher and seeks to protect her, often half-jokingly asking if they still have a chance together. (Source: Wikipedia)
