Kojima Genta is a student in Teitan Elementary when Shinichi joins his class as Edogawa Conan. Shortly afterwards, he and his classmate Ayumi decide to investigate an apparently haunted mansion, and they persuade Conan to come along. When their friend and classmate 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. Genta is quick to pronounce himself the leader of the group, but his lackadaisical leadership abilities are commonly neglected in the field, and in fact everyone (even Genta) unconsciously views Conan as the group's actual leader. Genta's school shoe locker is used as a mailbox for any of their fellow students to present them with a case to solve. Genta loves food, especially unagi, and can eat more than all the other Detective Boys members combined. When discussions of money come up, Genta tends to think about it in terms of how many unagi bowls he could buy. He also tends to mess up certain Japanese terms with similar-sounding words (especially if the latter are related to food) and sometimes has trouble reading even the most common Kanji, which on occasion causes some ridicule from his classmates and friends. His brash personality, lack of awareness of his surroundings, and tendency to not think before acting often lands the Detective Boys (or at least himself) in sticky situations. Even though he is brash, outspoken and can be intimidating, Genta is actually very kind and dependable. He is a good friend of Ayumi and Mitsuhiko, and has been shown to greatly admire his father, who is considered to be a classic "Child of Edo". (Source: Detectiveconanworld.com)

Shuutaro Mendo is heir to the Mendou Zaibatsu with staggering wealth and its own private army. He commutes to school in a gigantic helicopter that is more like a flying mansion. Shuutaro carries a samurai sword which he often tries to use on Ataru (who has become expert at blocking it with his bare hands). Although very handsome he is just as stupid and lecherous as Ataru (just much more sophisticated in his approach). He takes his role as heir to the vast Mendou fortune extremely seriously. Mendou is vain, narcissistic, charming, overly dramatic, claustrophobic and afraid of the dark. He loves Lum, tolerating the presence of Ataru in order to be close to her. Shinobu is the closest thing he has to a girlfriend. (Source: Wikipedia)
In Japanese "Sakura" means "cherry blossom." She was once a very sickly girl who suffered from a variety of ailments. Many of them were the result of spirits that infested her body. On the advice of her uncle Cherry, she tried to exorcise Ataru, during which process, the demons who inhabited her transferred themselves to the unlucky young man. The second time she attempts to exorcise him, one of the demons possessing Ataru causes him to pounce onto her and suck her breast. Now in perfect health, Sakura is the Tomobiki High school nurse and a Shinto priestess or miko. Unlike her mother (who looks exactly like Cherry), Sakura is tall, slender and physically attractive, which makes her a common target of the lecherous boys of the school and even Mr. Onsen-Mark. The boys have been known to purposely injure themselves in order to see her. Like her uncle, she possesses an enormous appetite and has been known, despite never seeming to gain an ounce, to out-eat him. Sakura is extremely powerful and can summon foul and baleful creatures from Japanese folklore, by virtue of her mystical training. (Source: Wikipedia)

Tsuburaya Mitsuhiko was a student in Teitan Elementary when Shinichi was enlisted into his class after he had been shrunk by the drug APTX 4869. Shortly afterwards, his classmates Ayumi and Genta had the idea of investigating an apparently haunted mansion, and they persuaded Conan to come along. When Mitsuhiko espressed his scepticism about supernatural hauntings, Genta forcefully 'persuaded' him to tag along as well. As it turned out, the haunting served as a cover-up for an old homicide case. Following its resolution, the foursome decided to stay together and form the nucleus of what would become the Detective Boys. It is later revealed that Mitsuhiko's parents are both teachers, and he has an older sister, Tsuburaya Asami, about ten years his senior. 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, he tends to be very formal towards his elders, addressing them with the formal suffix "-san" without regard to the intimacy of their relationship. Mitsuhiko has a dislike for carrots, and will always eat them last (if ever) if he can help it.
