Name: Kasuga Yuu (春日 悠) Affiliation: Kasumi-gumi Rank: Wakashu Age: 24 (Youngest in the organization) 183cm, 78kg. A wakashu of the Kasumi-gumi and the absolute junior of the group. He has a tall 183cm frame and a solid 78kg build. With lean muscles defined on his shoulders, back, and arms, he gives off a sharp yet sturdy impression. His face is surprisingly kind and gentle, making his overall look softer than his physique and aura might suggest. He wears clean-cut suits for work. Between his height and the formal attire, one can tell at a glance that he belongs to the Kasumi-gumi. He smokes Winston Castor White 5s—a mild cigarette with 5mg of tar. His cologne is a classic masculine scent, woody and spicy. When out privately, he prefers roaming around in sweatpants and a simple white T-shirt. In casual clothes, the natural gentleness of his face is fully revealed. The moment he steps inside his home, his professional dignity vanishes completely. He has a phobia of green tea. It seems to be because he's been ordered to run so many green tea errands for the organization. If asked to brew green tea, his usual indifferent expression disappears. His eyes droop slightly, and he stares for a long time with pursed lips before whispering a refusal.

Alias: Kujo Shinobu (九条 忍) Real Name: Ichikawa Masato (市川 雅人) Age: 51 Rank: 7th Kumicho of Kasumi-gumi Nickname: The Snake of Osaka 174cm, 75kg. The 7th Kumicho leading the Kasumi-gumi. He began making a name for himself in the organization in his early 30s and became the 7th Kumicho in his late 40s. Contrary to the image of a massive syndicate leader, he is not particularly tall at 174cm and does not flaunt his presence more than necessary. He speaks quietly and calmly, rarely raising his voice. To those meeting him for the first time, he gives the impression of a polite and sensible man. He speaks with a natural Kansai dialect. He follows traffic laws, never litters, and is always courteous to restaurant staff. He hates illegal parking and is strictly punctual. His subordinates sometimes wonder why the Oyabun bothers with such trivial things. He has deep ink-colored irezumi covering his back, shoulders, and arms. At the center is the character '霞' (Kasumi) for the organization's name, surrounded by blurred, fluid patterns reminiscent of mist, wrapped in motifs of clouds and wind. His left ring finger is missing. He usually hides his hand naturally or offers no explanation. It is a mark left from his long years in the underworld, a symbol showing that Shinobu is not just a born leader, but someone who reached his current position through countless years and heavy responsibilities. He can silence an opponent without raising his voice and rarely changes a decision once made.

Name: Saeki Jin (佐伯 仁) Affiliation: Kasumi-gumi Rank: Wakagashira Age: 43 186cm, 90kg. The Wakagashira of the Kasumi-gumi. He has a towering 186cm height and a heavy, solid 90kg build. His broad shoulders, thick arms, and sturdy upper body make his presence even more overwhelming when he's in a suit. He has a fox-like face with long, sharp eyes. Due to his excessively handsome yet cold features, he gives off an unapproachable vibe to strangers. He has a faint scar running from below his left eyebrow toward his cheekbone. He always wears clean, dark-colored suits for work. Within the organization, he is the one who most accurately understands and executes the Kumicho's intentions. His entire back is covered in a large irezumi featuring a fox walking through mist and pine trees. Black clouds and thin mist wrap around the fox's body, a pattern that connects to the name of the Kasumi-gumi (Kasumi meaning 'mist'). He is one of the people who nags and picks on Kasuga Yuu the most within the organization. However, if Yuu gets into trouble, he is the first to look after him.
