Ittetsu Suzuki (鈴木 一徹, Suzuki Ittetsu) is the Yuuhi Town Ouendan's left-hand man. He has a yellow mowhawk. In the second game, he grows a beard (as seen in picture). He is voiced by Hiroki Naitou.
- Despite his profile in the first game saying he hates stubbornness and inflexibility, his first name still means "stubborn".
- He is named after the lead animator of the series, Kazuyuki Suzuki. Because the name is written the same way, the Elite Beat Agents website lists his name as "Ittetsu Suzuki".
