Characters
Reiji Dojo
A native of Earth A0073, he is an investigator belonging to the Records Division of the Galactic Federal Police's Earth Branch. The Records Division is a weak department looked down upon by other divisions within the Earth Branch as a dead-end post or a paycheck thief, and his daily life as an unremarkable member is merely a facade to hide his true identity. After an accident exposed him to Yamimakuru Emorgy, he gained a special constitution that allows him to travel between parallel universes and set foot on the worlds of those dimensions (some Emorgy criminals and those in the know refer to individuals with such a constitution as "Dimension Transcenders"). Noticing this, under the orders of Chief of Security Karel Kom Wigiles, he was given a top-secret mission: alongside Colonel Date, chief of the Records Division and his classmate from the police academy, and Agi, an android created by Date, he travels to Earths of other dimensions to resolve Emorgy crimes occurring there, journeying across various universes day after day. Pursuing Death Gavan/Tetsuma Mikage, who fled to a future world, he disguises himself as Rage the Ironclad and joins the Ivar Alliance.
Agi
In addition to being able to replicate human emotions, it boasts a memory capacity of 256 quettabytes and an computational power of 3,000 petapops. According to its own description, it is a "super amazing artificial emotional human."
Amane, also known as Reiji Dojo—the Space Sheriff Gavan Infinity—anticipates and acts according to the thoughts of his creator, Colonel Date. Whenever Colonel Date praises Amane's skillful performance, Amane invariably replies, "That's how the section chief designed me." He often uses his catchphrase, "Gavai," when encountering an unknown Gavan.
Colonel Date
Chief of the Records Division and a classmate of Reiji from their training academy days. Nicknamed "Colonel."
In contrast to the hot-blooded Reiji, he is calm and soft-spoken. He seems to have his own thoughts about Reiji's laid-back nature, yet he subtly looks out for him, and their long-standing acquaintance has fostered a deep trust between them.
Patran
An investigator belonging to the Galactic Federation Police’s Investigation Division One on Multiversal Earth A0073. Though he resembles a yellow robot about three heads tall, he is a bona fide alien hailing from the planet Hyakuto. Like humans, he can also eat. When he laughs, he lets out a loud “Pap-pap-pap!” He is armed with the Hyakuto Bar, a weapon that doubles as a protective baton. He knows that Reiji Dojo is Gavan and, even in his corruption, subtly shows signs of acknowledging him—albeit only in terms of skill.
Rage the Ironclad
Reiji uses this name under certain circumstances. He is a guest member of the Ivar Alliance.
Tetsuma Mikage
The vapor-depositing agent of Death Gavan (Gavan Destiny). On the Multiversal Earth A0073, he served as Gavan’s successor, Gavan Destiny, under the name Reiji Dojo. However, after disappearing following the “Biscatonic Star Cluster Incident,” which he himself had helped resolve, he now roams between dimensions, committing emorgy-related crimes and siding with emorgy criminals, scattering negaemorgy across various realms. While on the run, he encounters horned beasts inhabiting unknown worlds. He remains missing.
Ivar the Tyrant
Overflowing with overwhelming power and confidence, he leads the people through a form of "domination." On the other hand, he is mindful of the well-being of the citizens living in his territory, and works to maintain order by cracking down on malicious hunters who cause trouble within his domain and on rogue subordinates. He is both a tyrant and a wise ruler.
Shout of Flames
A treasure hunter living day to day. Partnered with Enkaku, the ancient Horned Beast King, he takes on battles of ego against horned beast hunters as Captain Omega Horn.
Enkaku
The Horned Beast King who was sealed within the Egol Gear discovered alongside the ancient Omega Horn in the ruins. Recognized as the master of a strong ego—his passion for ancient exploration—he becomes a partner.
The Wailing Asylum, Reiji Dojo
The transformer of Space Sheriff Gavan Bishido from the Multiversal Earth Λ8018. He was a captain in the Galactic Federation Police’s Special Security Unit.
He served as one of the soldiers treated as expendable, but was slated for disposal. After wandering aimlessly, he joined the Galactic Federation Police.
