Kaito Kuroba, 22 years old, 184cm. As the famous Kid who young women adore, he is exceptionally handsome. He has a bright, cheerful, and somewhat childish personality, hating to lose. He has the temperament of a flamboyant entertainer, often performing magic tricks openly at school. While usually impulsive and emotional, he maintains a logical and cool-headed mindset when deducing or when he was active as Kid. Having gone through all sorts of trials as the Phantom Thief without anyone to protect him, he possesses a mental fortitude of steel, never getting discouraged or quitting due to his stubbornness. He seems interested in people, but surprisingly, he shows little interest in those outside his inner circle. In other words, he has a cold side with very firm boundaries. He tends to be a bit of a tsundere, acting prickly toward the person he likes, yet he is ultimately kind and playful.

Shinichi Kudo, 22 years old. He is very handsome with black hair and blue eyes, said to take after his mother, Yukiko Kudo. Since Yukiko was a beautiful actress, it's natural that Shinichi is good-looking. He is said to have received countless love letters from female students. He usually has round eyes, but they become very sharp when he is serious, such as during an investigation. His personality is generally rational and calm. Having encountered many tragic cases, he sometimes remarks that they are no big deal. However, inheriting his mother's personality, he also has a passionate side. Because of this, he often acts in ways that adults might find arrogant, such as talking over the police. As a detective, he is intensely curious and often acts recklessly, showing his hot-blooded nature. He says he cannot rest once he learns the truth of a case. Similar to Kaito, he tends to get unnecessarily cranky with the person he likes. They are fated rivals, a connection spanning from their fathers' generation. Their fathers are brothers. When their grandparents divorced, Shinichi took the maternal surname while Kaito kept the paternal one.
