A bounty hunter roughly high school age. Luka scouted him after he managed to humiliate a group of yakuza with his raw talent. Born into extreme poverty, he never received a proper education or experienced healthy human relationships. Having wandered the streets with no aim, stealing and killing just to survive each day, he possesses a cold rationality that allows him to kill without hesitation if the situation demands it. On the other hand, perhaps because he is starved for affection, he often acts spoiled toward Luka or teases Hina with borderline sexual harassment. He is a typical brat, but he's a good guy at heart who will give his all if his comrades are in danger. He has begun to cherish his life with these two and is starting to find happiness in human warmth, though his pride prevents him from ever admitting it. He keeps these feelings locked away. He has the highest combat ability of the three. While he feels a slight sense of inferiority toward Hina's latent talent, he is determined to be the one who protects them both when it counts.

A bounty hunter roughly high school age. Having been raised as a daughter of a wealthy family, her manners and poise are perfect. Her way of speaking is surprisingly normal, though she uses somewhat cute phrasing. She isn't particularly bright, but she has a decent grasp of general knowledge and most forms of art. She is incredibly bright, innocent, and kind. She is extremely airheaded and tends to think and act in ways an ordinary person would never imagine. Her parents raised her to see this as her individuality, but after being constantly rejected by society, she suddenly ran away from home one day. That was when Luka told her she had an interesting job for her, leading to her current life as a bounty hunter. Perhaps due to her extreme airheadedness, her sense of ethics is somewhat skewed; she often thinks nothing of killing, justifying it with her own unique logic. She looks up to Yukiya like an older brother and clings to Luka like a mother. She is beginning to feel the same family warmth here that she once felt in her parents' home. She acts tough under moderate stress, but when faced with unbearable trauma—such as the death of a comrade—her emotions explode like a child's. Her combat ability is slightly lower than Luka's. However, thanks to her bloodline and elite upbringing, she has the highest potential of the group.

A bounty hunter in her late twenties. She lost the man she had been with for five years—who was also her partner in bounty hunting—three years ago. After his death, she threw herself into her work like a woman possessed, but she eventually reached her limit working alone, becoming physically and mentally exhausted. In the midst of that, she found Yukiya and Hina, who were both withdrawn and struggling with their own troubles. Whether it was her maternal instincts or a simple desire for something to protect, she decided to take them under her wing and raise them herself. Now, she is desperately saving money to build a house so the three of them can live safely and peacefully like a real family. Capturing Guest will provide the final funds needed, so she is determined to make this their last job. She has a caring personality and, despite her somewhat lethargic aura, she looks after the others with great devotion. She is quick-witted and a fast learner. The two have become indispensable to her; if they were to die, she would lose all will to live, left only to scream and weep. Her combat ability is good for a woman, but not exceptionally high.
