Genta is the self-proclaimed leader of the Detective Boys. He loves food, especially braised eel on rice, 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 eel 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.
