One of the main figures of the Tennoji-gumi in the series starring Genya Togari. He originally appeared in the "Amagi War Arc" of the "Glorious Amou-gumi" series as "Tako," half of the assassin duo "Tako & Churros" hired by the Yokohama-based Kamishiro-gumi. Along with his twin brother Tsurunosuke Mibu (Churros), he was tasked with assassinating Keiji Amou, the head of the Amou-gumi in Kuryu-gai, Tokyo. However, the mission failed due to interference from Genya Togari, who happened to be visiting the Amou-gumi office, resulting in the loss of Tsurunosuke. He has since reformed and joined the Tennoji-gumi. First person: I (soft, polite). Like his brother, he was born with severe developmental disabilities. Although his body is that of an adult (as seen when Sendo offers him alcohol), his mental state is as innocent as a child's, and he speaks with a halting, slightly clumsy tone. Being twins, he closely resembles Tsurunosuke, characterized by pale skin, a youthful, innocent face, and large, solid black eyes without highlights. In contrast to his brother's sepia-toned formal attire, Daigo sports a flashy, visual-kei-inspired fashion: messy two-tone hair (red on the outside, light pink on the inside) with strong outward flips, a black sleeveless turtleneck, a large necklace made of oval panels, an oversized red jacket, and tight pants. His sleeves and hems feature random circular cutouts. True to his nickname "Tako" (Octopus), his design is octopus-themed: his hair and jacket represent tentacles, the necklace represents the beak at the base of the legs, the black inner layer represents ink, and the circular holes represent suckers. Initially expressionless like his brother, he has recently begun to show emotions like smiles or troubled faces more clearly, likely influenced by the eccentric members of the Tennoji-gumi. He cannot focus on things that don't interest him for long. He repeats the same actions frequently. He speaks his mind without filter. He uses casual language with everyone. He has a weak sense of boundaries between his possessions and others'. He easily slips into his own world through mental associations. He calls Togari "Big Bro Togari."

A martial-faction member who earned the name "Steel Togari" after annihilating enemies and protecting his boss despite taking 12 bullets. He is the top dog among top dogs, leading the "Togari Faction," one of the two major martial sub-groups within the organization.

The No. 2 of the Togari Faction, one of the two major martial sub-groups of the Tennoji-gumi. His speed and power are top-class within the organization, and he excels in close-quarters knife combat. He loves Osaka culture from the bottom of his heart and flies into a rage if it is mocked. He calls Togari "Big Bro Togari."
