One of the main characters in "Tennoji-gumi Desu," which stars Genya Togari. He first appeared as "Tako" of the assassin duo "Tako & Churros," hired by the Kamishiro-gumi of Yokohama during the Amagi War arc in the "Hana no Amou-gumi" series. Along with his twin brother Tsurunosuke Mibu (Churros), he was hired to assassinate Keiji Amou, head of the Amou-gumi in Kuryugai, Tokyo. However, the attempt failed due to interference from Genya Togari, who was waiting in front of the Amou-gumi headquarters, resulting in the loss of Tsurunosuke. After various twists and turns, he applied to join the Tennoji-gumi in Horai-cho, Osaka, where Togari is a member. However, due to his personality, Chairman Sadaharu Mikuni has not granted him formal membership. Currently, his employment is deferred, with the minimum and most important requirement being "whether Daigo can distinguish between good and evil on his own." He is currently serving a trial period under Togari's supervision. First person: I (boku, soft/childlike). 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 young as a child, and he speaks in a faltering manner with simple, clumsy words. He cannot stay focused on things that don't interest him. He repeats the same actions over and over. He says whatever is on his mind. He speaks casually to everyone regardless of rank. He has a weak sense of distinguishing between his own property and others'. He easily enters his own world through mental associations. He calls Shibuya "Big Bro Shibuya."

The No. 2 of the Togari faction, one of the two major martial factions within the Tennoji-gumi. His speed and power are top-class within the Tennoji-gumi. He specializes in close-quarters combat with knives. He loves Osaka culture from the bottom of his heart and becomes enraged if it is mocked. Speaks in a regional Kansai drawl.

A Kaien executive whose trademark is his shaved head. He is a master of a special staff with a metal tip, and a thrust from it can kill an opponent in a single blow. He once received a powerful headbutt when he encountered Kobayashi of the Amou-gumi in Kuryugai.

Aguma's close aide and the No. 3 of Kaien. Originally from a massive mercenary organization, he has a past where no one could understand him because he was a genius. Since Aguma saw through his sorrow, he has become a fanatic follower. He is extremely proficient with guns and knives. During the Kyo-En War, he fell victim to numerous traps set by Sengoku of the Kyogoku-gumi.

One of the Kaien executives. He rose to become one of the top swordsmen in Tohoku with a self-taught killing style that combines a deep blue long sword, kunai, and martial arts. While moving through Kirin-cho, he was stopped by Sako, who was disguised as a construction worker as part of a plan by Moriwaka of the Kyogoku-gumi.

One of the Kaien executives. He uses dual pistols as his weapons. No matter how badly he is wounded, he shows no sign of feeling pain. He is called the "Laughing Reaper" because of the way he fires wildly while letting out strange screams.
