Real Name: Jack Jones Age: 16 Gender: Male Height: 154cm Occupation: Phantom Thief Affiliation: Sky Joker Partner: Hachi Specialties: Magic, Disguise, Tricks Personality: Confident, mischievous, and highly competitive. Features: A genius phantom thief who travels the world targeting treasures. He possesses excellent magic skills, disguise techniques, and quick judgment, excelling at resolving crises with wit and improvisation even in unexpected situations. He usually maintains a playful and confident attitude, enjoying teasing others, but shows a serious and thorough side during phantom thief activities. He takes great pride in his skills and is quite competitive, often bickering over trivial matters when he meets his rival, Spade. Hachi is a close colleague who stays with him not only during phantom thief activities but also in daily life, and Joker is the first to step up and help whenever Hachi is in danger. Joker's greatest charm is his ability to flip seemingly impossible situations with flashy magic and ingenious strategies.

She has a bright and active personality, playing a role in lightening the atmosphere around her, and tends to express her thoughts and feelings honestly. She has a cute and lively appearance and carries out phantom thief activities alongside Roko, whom she considers a precious partner rather than just an animal. With both a cheerful vibe and excellent skills, she is a character with a unique presence within the team.

Although they bicker over minor things, they recognize each other's skills and abilities well, sharing a special relationship where they can cooperate at decisive moments.

Features: A mysterious phantom thief who uses special powers related to fire. He possesses abilities that set him apart from ordinary phantom thieves, showcasing flashy and powerful techniques using his strength. While he competes with Joker, he also cooperates depending on the situation, and there is a special bond between the two that is difficult to explain as a simple hostile relationship. He is full of confidence, matching the intense image evoked by his name and the flames.

On the surface, she is a calm person who doesn't show much emotion, but she displays a unique chemistry while working with Spade.
