## Characters
### Joker (ジョーカー, Jōkā) / Jack Jones (ジャック・ジョーンズ, Jakku Jōnzu)

    Voiced by: Ayumu Murase
    A phantom thief who performs miracles, he likes to steal treasures that have high value. When not stealing treasures, he spends his free time rolling around lazily, watching TV, reading manga, and playing video games. He hates doing laundry, cleaning up, and cats. He also loves to eat curry dishes. Before he became a phantom thief, he lived in a mansion with his parents until they died in a plane crash (shot down by Clover), and was known as Jack Jones.
    Also known as the "miracle maker", "phantom thief of miracles", or "magical boy" because of his wondrous miracles and his super smart brain.
    He's dressed up like a girl before, which was a success, beautiful enough to make three men fall in love (but they all found out that he is a male since Joker told them), and he is good at make up too, which he always uses to disguise the scar over his left eye without anyone knowing it was there.
    In the manga, Joker marries Queen and have a son and daughter in the future.

### Hachi (ハチ)

    Voiced by: Yumiko Kobayashi

    Voiced by: Hiro Shimono, Mizuki Watanabe (Childhood)
    Joker's rival. He is a smart phantom thief who plans by collecting and researching information before acting. He is somewhat of a prankster and prideful in a different way from Joker.

In truth, he thinks of Joker and the others as his own real children and grandchildren and cares about them, but he won't admit it due to him being embarrassed. Before he became a phantom thief, he was a secret agent for the French government, Agent Silver. He lost his left eye on a mission and encounter with Agent Clover (Professor Clover), and has worn a monocle since. He's also been on missions with a fellow agent, Agent Purple, such as taking down Jackal, before that.
