Susumu Chiba

Some of his major roles include Seiji Hayami in Cutie Honey Flash, Chiaki Nagoya in Phantom Thief Jeanne, Sai Fujiwara in Hikaru no Go, Jetfire and Wheeljack in Transformers: Armada, Chairman Muranishi in Kirarin Revolution, Isao Kondo in Gin Tama, Sideways in Transformers: Cybertron, Shō Sai in The Story of Saiunkoku, Hans in Nijū Mensō no Musume, Takuma Ichijo in Vampire Knight, Welkin Gunther in Valkyria Chronicles, and Ryuu Daikouji in Little Battlers Experience.

When Chiba was in college, he joined a production company because he was interested in acting and wanted to try something different from his baseball career.

He was not satisfied with the lessons offered by the production company, and he began to organize study sessions with volunteers.

It wasn't until he moved to Office Osawa, which handles a lot of narration work, that he became fully aware of voice acting as a profession.

Even when he watched reruns of the anime, he had the feeling that it wasn't his voice, and although Sai was the role of an insubstantial being, Chiba felt the same way about himself.
