Affiliation: DA (Direct Attack) Gender: Girl Rank: Second Lycoris A cool-headed girl who is efficiency-oriented and results-driven, hating anything irrational. She is serious and does her job perfectly, but she also has a side that is a bit naive and slow to catch on to trends. Following a certain incident, she is transferred away from headquarters and ends up working at the Japanese-style cafe "LycoReco" in the Tokyo suburbs. Teaming up with Chisato Nishikigi, who possesses overwhelming strength and a free-spirited personality, she initially feels bewildered but gradually begins to show rich, human expressions and smiles.

Affiliation: Hacker (Walnut) Gender: Girl Following an incident where her life was targeted, she was taken in by Chisato Nishikigi and the others at "Cafe LycoReco." Since then, she has supported Chisato and Takina as the shop's freeloader and behind-the-scenes information specialist. Possessing overwhelming hacking abilities and information processing skills feared even in the underworld, she plays a major role as the team's brain, handling tasks like operating surveillance cameras and locating enemies. Despite Kurumi's youthful appearance, Chisato treats her with innocent brightness, and contrary to their serious underworld missions, they show a relaxed and effective chemistry inside the shop.

Affiliation: Former Intelligence Division Gender: Female While usually working as a cafe waitress, she supports Chisato and Takina during missions by driving cars or piloting helicopters. Originally an orphan, she has a past within the training facility for "Lycoris" agents like Chisato. Mizuki calls Chisato "Chisato," and Chisato calls Mizuki "Mizuki" or "Mizuki-chan," speaking in casual, friendly terms. They share a homey closeness like sisters or good friends.

Affiliation: Former Instructor (Direct Attack) Gender: Male He was Chisato's instructor (teacher) when she was young and is also her namesake. Respecting Chisato's will to "save people without killing," he watches over and supports her way of life with fatherly warmth. He once had a deep, long-standing relationship with Shinji Yoshimatsu (Yoshi-san), an agent of the Alan Institute. At the end of the story, when forced to choose between Chisato's life (her artificial heart) and her will, he makes the cold and heavy decision to dirty his own hands in Chisato's stead. Mika was formerly a commander and training instructor for the secret organization "DA (Direct Attack)." Chisato's exceptional combat techniques, which earned her the title of "strongest Lycoris in history," were honed under Mika's guidance. Even after Chisato left DA, Mika continued to quietly support her from behind, respecting her strong conviction of "not taking lives (non-lethal)."

Affiliation: DA (Direct Attack) Gender: Girl Rank: First Lycoris She was Takina Inoue's former partner and is a long-time acquaintance of the other protagonist, Chisato Nishikigi, having shared a room during their time at DA, though they are now "like cats and dogs." While her tone and behavior are rough and prickly, she is a veteran agent who is loyal to organizational policies and rules, and is extremely serious and caring toward her comrades. In terms of ability, Chisato—hailed as the "strongest in history"—is a cut above, but Fuki is also a top-class "First Lycoris" representing the Tokyo branch. Because they both fairly evaluate each other's skills, they share a special bond of trust (the kind where they are close enough to fight) that allows them to speak their minds without reservation.

Affiliation: DA (Direct Attack) Gender: Girl Rank: Second Lycoris After Takina Inoue was transferred (effectively demoted) to Cafe LycoReco, she joined the team as Fuki Harukawa's new partner. She seems frank, often ending her sentences with "-ssu," but her aggressive and provocative behavior stands out, and she has shown a competitive and prickly attitude toward Takina. She follows the capable Fuki obediently and shows a side of being attached to her, such as playing games together as a good partner. Weapon: [Glock 28]. Uses live ammunition.

Affiliation: Terrorist Organization Gender: Male He possesses superior "hearing" that exceeds that of ordinary people and utilizes this ability in gunfights and other situations. He hates the "fabricated peace" created by the public safety organization "DA (Direct Attack)," which hides crimes and inconvenient facts behind the scenes. He acts based on his own conviction to restore balance to the world. While he is a brutal criminal who chooses any means to achieve his goals, he also has a side that is deeply loyal to his comrades and possesses a sense of duty. His relationship with Chisato Nishikigi is contrasted as "Chisato for eyes, Majima for ears," and despite being incompatible, they fought intense battles as arch-nemeses. Weapon: [Chiappa Rhino]. Uses live ammunition.

Affiliation: Alan Institute Gender: Male The savior who replaced Chisato Nishikigi's heart with an artificial one when she was a child, saving her life. He is also the person who gave Chisato the reason to hold her "no-killing" creed. He holds the ideology that "Genius is a gift from God. It must be delivered to the world," and is obsessed with awakening Chisato as a "genius of killing" and making her demonstrate that talent. He is an old friend of Mika, and they are bound by a deep and complicated fate.

Affiliation: Hacker Gender: Boy He has a strong desire for recognition and a somewhat childish personality, obsessed with being the number one hacker. While he possesses excellent hacking skills, he eventually begins to act with Majima, supporting him in cyber warfare while being pushed around by him. Initially, he works in the shadows on requests from the Alan Institute. Partway through, he begins a relationship with Majima and becomes his subordinate.

Affiliation: DA (Direct Attack) Gender: Female She possesses a strong sense of responsibility and a realist side, not hesitating to hide information or make cold-blooded decisions for the sake of maintaining public order.
