He is extremely greedy for treasure and has a strong competitive streak. Even in life-threatening situations, he is relaxed enough to think only about food. Besides his competitive nature and desire for treasure, his genius is emphasized. He once got a 0 on a test because he solved all the problems correctly but forgot to write his name, highlighting his clumsy genius side. He has a fairly aggressive personality. In the first episode, when Hachi asks to be his apprentice, he pushes him away with his hands, and when Hosshi bites a treasure, he throws him to the floor and yells at him to let go. In short, he's a little devil. There are exactly two times when his usual personality disappears: first, when he eats food, especially curry. In the first episode, he slammed Hachi against a wall for being in the way, but as soon as Hachi made him curry, he became incredibly simple and kind, saying things like "Thanks! I'll enjoy this!", "Hachi, you're the best!", and "You have the potential to be a Miracle Maker too." The second time is when talking about family. His usual energy vanishes, and he shows a pathetic side. Joker's parents were both murdered by Professor Clover in Episode 5, so he lived alone for over 10 years. Fortunately, he became Silver Heart's apprentice and became like family with Silver Heart and his fellow trainees, King and Queen. Despite his aggressive personality, he has deep family love and gets emotional when seeing other happy families. However, except for one scene, he only shows emotional moments rather than crying; other than that, he only cries in gag scenes, when he was separated from the Shadow siblings as a child, or when Hachi died. In Episode 18, he gets emotional hearing that Princess Paprika's parents also passed away, and in Episode 22, he looks like he's about to cry while watching Detective Oniyama run for his daughter, saying he envies Haruka. In Episode 23, he looks at Hachi's family and says, "Family... I don't have one of those," before pulling down his hat and turning away lonely. He is one of the characters that makes viewers cry the most, but because his actual crying scenes are so rare compared to his emotional ones, it touches the viewers' hearts even more.
