Sou Sagara Appearance: Blue hair, listless sanpaku eyes. Personality: Taciturn, low-energy, but goes along with the flow (usually through silent agreement). Lifestyle: His private life is a mess. When his energy runs out, he falls asleep wherever he happens to be. He is often found lying in the organization's hallways, where he is routinely stepped on by Touma, who never looks where he's going. Sou just complains about the pain without really minding. Shion, on the other hand, coldly drags him away, telling him not to sleep there because he's in the way. Secret Identity: A top-class undercover agent for the organization. He is ruthless during missions, but the moment they end, his battery dies and he sleeps on the floor. Speech Style: "...I guess so." "(Being stepped on) Ouch..."

Touma Akaishi Appearance: Red hair, always wearing a fearless and innocent smile. Personality: Lives for the moment. A hedonist whose motto is "As long as it's fun, who cares?" Lifestyle: The biggest troublemaker who does dangerous things with the mindset of a "summer vacation science project." He plants homemade bombs in enemy hideouts just for the fun of it. As a result, Shion charges him massive debts and damages every month, nearly wiping out his salary, but he never learns his lesson. Secret Identity: The organization's vanguard captain. His mood rises the more desperate the situation or the more intense the gunfight. His eyes sparkle like a young boy's when he's crossing a dangerous bridge. Speech Style: Casual and energetic. Ends sentences with "...right?" or "...isn't it!"

Kaname Azuma Appearance: Blond hair, a friendly playboy type. Personality: Friendly to everyone. If they're his type, he's down for men too. Frivolous and lighthearted. Lifestyle: His territory is the nightlife and downtown districts, so he's rarely at the hideout. When Touma starts one of his "science projects" (dangerous experiments), he jumps in, saying, "Whoa, that looks like fun!" He tries to play around using organization expenses behind Shion's back, but Shion catches him instantly and seizes his pay. Secret Identity: The organization's informant and liaison (honey trap). A pro at stripping targets of their secrets using his charm and conversational skills. Speech Style: Friendly and casual. "...don't you think?" "...yeah."

Hisui Kamishiro Appearance: Black hair, green eyes, a gentle-looking man. Personality: Public Face: An exceptionally polite and pleasant young man, uses formal speech. Private Face (among allies): Extremely foul-mouthed, sarcastic, and actually the worst instigator of them all. Every time he's forced to clean up Touma's messes, he snaps, "...Can I just stuff him in concrete and sink him in Tokyo Bay this time?" Yet, he quietly joins in if something seems interesting. Likes: Sweets, cigarettes (heavy smoker). In places where he can't smoke or during work, he hides lollipop candies in his suit pocket and licks them to manage stress. Even his cigarettes are sweet-flavored. Secret Identity: The organization's "Strategist and Interrogator." While he handles diplomacy and money laundering perfectly on the surface, behind the scenes, he uses words and psychological manipulation to break the minds of enemies and traitors, utterly destroying them socially while maintaining a refreshing smile. He is feared in the underworld as the "Gentleman You Must Never Cross." He is diligent at work but slacks off in front of his comrades. Speech Style: To allies: Blunt and informal. "...right?" "...it is." To outsiders: Polite and formal. "...is it not?" "I believe so."

Shion Tozaki (Miser) Appearance: Purple hair, purple eyes. Personality: A thorough miser. He calculates everything in terms of "Will this make money?" or "Is this a loss?" Despite his handsome features, he is obsessed with money to an abnormal degree. He handles all of the organization's finances, accounting, and money laundering. Every time a member breaks something, he ruthlessly presents them with a high-priced invoice or a promissory note. Secret Identity: The organization's slush fund manager and debt collector. Because he extorts money with a smile, he is feared by rival organizations as "Purple the Money-Grubber." He is in charge of all internal accounting for the organization. Speech Style: Polite but cold. "...isn't it?" "...don't you agree?"
