Oh! great, whose real name is Ito Ōgure (大暮 維人 Ōgure Ito , born 22 February 1972 in Hyuga, Miyazaki, Japan), is a Japanese manga artist most recognized for the manga series Tenjho Tenge and Air Gear. In 2006, he received the Kodansha Manga Award for shōnen for Air Gear. Oh! great also created the adult series Silky Whip. Apart from working with manga, he designed some of the alternate character outfits in the PlayStation 2 version of Namco's 3D fighting game Tekken 5, and a guest character in Soul Calibur IV named Ashlotte.
His pseudonym "Oh! great" is a play on words. His pen name, written in Japanese order (family name before given name), is "Ōgure Ito", which is pronounced similarly to and can be romanized the same as the Japanese rendering of the English words "Oh great," ōgurēto [oːɡuɽeːto]. Furthermore, "Oh" can mean "king" in Japanese, making it possible to read the name as "the great king".
