Toshihiko Seki (関 俊彦, Seki Toshihiko, born June 11, 1962) is a Japanese actor, voice actor, singer and narrator. In June 2004, Seki was honored by the readers of Animage Magazine in the 26th Annual Reader's Poll, where he was ranked the 9th favorite voice actor, largely in recognition of his performance as Rau Le Creuset from Mobile Suit Gundam SEED. In August 2007 the Anime News Network called him one of the more prolific male voice actors with 215 roles credited to his name. Seki often voices characters who are very serious or easily agitated like Duo Maxwell in Mobile Suit Gundam Wing, Iruka Umino in Naruto, Kaien Shiba in Bleach and Genjo Sanzo in Saiyuki but he also plays deranged villains like Legato Bluesummers, Rau Le Creuset, Embryo and Muzan Kibutsuji. His most famous role is the Imagin Momotaros from Kamen Rider Den-O, reprising the role numerous productions since then.
