George Kojima, known as Genta Kojima in Japan, is the overweight, self-proclaimed leader of the Junior Detective League. He loves food and can eat more than all the other Junior Detective League members combined. Even though he can be intimidating, he is actually very kind. He is a friend of Amy Yoshida and Mitch Tsuburaya, and has been shown to admire his father, who owns a liquor store. Both he and Mitch have a crush on Amy, and they both envy Conan since she likes him.

He should sound a bit goofy and a bit raspy, not too goofy though, I would like for him to be voiced by a man who can do a good kid impression
