Mitsuhiko Tsuburaya is a student in Teitan Elementary when Shinichi joins his class as Conan Edogawa. Shortly afterwards, his classmates Ayumi and Genta have the idea of investigating an apparently haunted mansion, and they persuade Conan to come along. When Mitsuhiko expresses his skepticism about supernatural hauntings, Genta forcefully 'persuades' him to tag along as well. As it turns out, the haunting is a cover-up for an old homicide case.
Soon after, the accidental acquisition of a treasure map leads Ayumi, Genta, Mistuhiko and Conan on a hunt for a cache of stolen Italian gold coins, during which Conan saves them from getting killed by the mafia members who are also after the gold. After the case is resolved, Mitsuhiko joins Genta and Ayumi in forming the nucleus of an amateur detective group, the Detective Boys.
 Plot overview
Mitsuhiko enjoys reading science books and takes a scientific approach to problem-solving. He is a smart and well-read first-grader who believes that technology can solve most problems. Due to his strict and formal upbringing by his parents, he tends to be very formal towards his elders, addressing them (in Japanese) with the formal suffix "-san" without regard to the intimacy of their relationship.It has been shown at numerous times that Mitsuhiko really likes to be prepared for any occasion. He enjoys studying scientific, historical and general subjects for his own interest and fun. This eventually allows him to provide useful insights whenever necessary. He's been (or felt) rewarded a few times for his knowledge. In one instance, Ayumi said 
One of his other qualities is that he tends to be pro-active in many situations and think ahead of possible outcomes. For example, while the Detective Boys were trying to solve riddles they found in a Momotaro container in a small river in Kurashiki, a murder occurred which eventually led to the different codes to get burned. Conan, knowing that resolving those codes would lead to concrete proof as to who the murderer might be, was quite pleased when Mitsuhiko proudly announced that he took notes in his Detective Boys notebook "thinking that something like that could happen". With time and experience, he will probably become about as intelligent as Shinichi Kudo and Heiji Hattori.
Mitsuhiko has a dislike for carrots, and will always eat them last (if ever) if he can help it.
 Relationship analysis
 Detective Boys
 Ayumi Yoshida
As the cheerful and innocent girl she is, Ayumi has attracted the romantic interests of her teammates Mitsuhiko and Genta, but she is blissfully unaware of that. Her crush on Conan and tendency to innocently flirt with him leads to feelings of annoyance or disappointment on Mitsuhiko's part. According to Movie 5, Mitsuhiko seemed to have liked Ayumi since kindergarten, and according to Magic File 2, they have been friends since at least pre-school.
 Ai Haibara
After Haibara joins the Detective Boys, Mitsuhiko develops a crush on her due to her intelligence and competence. To date, Ai hasn't shown any romantic feelings for him and uses his feelings to her advantage when she needs him to do something, but she also does admire his intelligence and courage during missions the Detective Boys must perform and respects his feelings. In some episodes she even shows more confidence in Mitsuhiko than in Ayumi or Genta when the going gets tough.
 Conan Edogawa
Mitsuhiko's relationship with Conan is a bit of a two-faced matter. While he generally admires Conan for his intelligence, courage and expertise, he tends to become very jealous of him whenever Ayumi has set her romantic intents on Conan.
 Genta Kojima
Mitsuhiko and Genta are generally on very good terms with each other, and are mutually jealous of Conan whenever Ayumi decides to give him romantic attention. However, the two do not feel rivalry with each other, likely because Ayumi sees them both as friends.
