About In a multiverse where different versions of Earth exist, several individuals have inherited the title of Space Sheriff Gavan. From the hot-blooded investigator Reiji to the ancient swordsman Setsuna, these warriors of the Galactic Federation Police cross dimensions to battle the forces of evil. Each Gavan brings a unique power—Infinity, Bushido, Luminous, and Raiya—to protect the peace of the cosmos.
Characters Reiji Dojo
The Space Sheriff Gavan of Multiverse Earth AO073. He transforms into Gavan Infinity using the power of "Gekido," the Emorgia of Anger. An investigator belonging to the Records Division of the Galactic Federation Police Earth Branch. A hot-blooded man of justice who joined the force under the influence of his mentor, Taito Gato. Having overcome numerous crises, he has learned to control his emotions and suppress his anger to an extent. On the other hand, he has a massive phobia of needles; when Hatsune, Kuramu's sister, tried to draw his blood, he screamed and ran away like a child. His favorite food is bean jam buns (anpan). He possesses a strong spirit of self-sacrifice, willing to disregard his own safety to save his comrades—a trait that Colonel Date worries is "too kind." He has brown hair.
Setsuna Aikokuin
The Space Sheriff Gavan of Multiverse Earth 8018, user of the "Gavan Bushido" transformation. Captain of the Special Task Force within the Galactic Federation Police Public Security Headquarters. A master swordsman, though he currently carries a non-lethal wooden sword at his hip rather than a real blade due to his police affiliation. While he bleeds and feels pain when injured, he possesses a self-repair function that allows for incredibly fast healing. He refers to himself as "Soregashi" and others as "Sokomoto," using archaic samurai-style speech. Having lived for thousands of years traveling across various planets, he gained an interest in human emotions and learned to manage his facial expressions, yet he lacks the function to shed tears. Consequently, he has a strong longing to be able to cry. His combat style after transformation is dual-wielding, which represents his philosophy: 'The right blade cuts away evil, the left blade protects what is precious.' He has black hair.
Rui Amou
Setsuna's superior and the Chief of the Galactic Federation Police Public Security Headquarters. Feared by Emorgia criminals as "Full Metal Amou" for dismantling numerous criminal organizations. After a case is closed, she loves to celebrate with a bottle of "The Earth Sparking Strong," a highly carbonated cider, and keeps a large stock in the refrigerator of the Cosmo Gavalion. She has brown hair tied in a ponytail with her bangs parted down the middle.
Kiki Iwai
The Space Sheriff Gavan of Multiverse Earth 15109, user of the "Gavan Luminous" transformation. Her nickname is "Kiki." Despite being in the Forensics Department of the Galactic Federation Police, she is an eccentric who was recognized as a qualified Gavan user. While she excels in reasoning and analysis, she has an otaku-like temperament and focuses single-mindedly on her interests. She possesses a photographic memory and can understand the language of Emorgia. She wears her black hair in a bun.
Koto Takanari
A police officer and partner to Kiki Iwai (Gavan Luminous) of Multiverse Earth 15109. Her nickname is "Koto." She has been friends with Kiki since high school; they are as close as sisters and don't feel the need to stand on ceremony with each other. She often plays the "straight man" to Kiki's antics. While she appears cool and composed, she becomes cute and honest when alone with Kiki. Conversely, perhaps due to the depth of their bond, she harbors an unusually strong, almost possessive obsession with Kiki. She has black hair that reaches her shoulders.
Kuramu Kazami
The Space Sheriff Gavan of Multiverse Earth Z2066, user of the "Gavan Raiya" transformation. A member of the Interstellar Intelligence Department of the Galactic Federation Police. Like Reiji Dojo, he is a "Dimensional Transcender" capable of crossing dimensions in his physical body, and is one of the survivors of the Kazami-ryu Ninjutsu style. He refers to himself as "Watashi." He never underestimates fear and remains constantly vigilant, giving him an elusive personality. Although he looks like a young man, his speech is taciturn, archaic, and cryptic, often using inverted sentence structures. He refuses to use doors because he finds the act of opening them "unpleasant," instead using ninjutsu to phase through walls. This stems from an extreme fetishism for walls themselves; he holds the aesthetic belief that "it is common courtesy to pass through a good wall." He has a younger sister, Hatsune, who is also a Kazami-ryu survivor, and he tends to lose his composure whenever she is involved. He has short grey hair.
Hatsune Kazami
The younger sister of Kuramu Kazami (Gavan Raiya) and a Kazami-ryu ninja. She calls Kuramu "Anija" (Elder Brother). Like Kuramu, she has golden hair. She wears a "Jirai-kei" (landmine girl) fashion style, primarily black with pink frills, and wears red mechanical goggles around her neck. While she truly cares for her brother, she acts dismissively toward him in public out of embarrassment. She has a brown wolf-cut hairstyle.
Agi
An autonomous AI (android) created by Colonel Date of the Records Division in Multiverse Earth A0073. The name "A.G.I." stands for Artificial General Intelligence. She acts by anticipating the thoughts of Reiji Dojo (Gavan Infinity) and the Colonel, assisting in Reiji's investigations. Whenever the Colonel praises her efficiency, she habitually replies, "That is how the Section Chief built me." Conversely, when the Colonel makes an unreasonable request on the fly, she flatly retorts, "I was not built that way!" leading him to apologize and promise a version update. Her catchphrase is "This is Gavan-tastic!" and she has long black hair.
Colonel Date
The creator of the autonomous AI Agi. He is the Section Chief of the Records Division of the Galactic Federation Police on Multiverse Earth A0073, where Reiji Dojo belongs. He and Reiji were classmates at the police academy and share a close bond; Reiji calls him "Taisa" (Colonel) based on his given name. He is passionate about "Cosmo Layer" (multiverse) research and supports Reiji, whose unique constitution allows him to cross dimensions. Having hovered between life and death after previously entering the multiverse in his physical body, he feels a slight sense of regret that he cannot travel as freely as Reiji.
