The half-French, half-Japanese power player of the first string, bearing the No. 3 badge. His power is immense, greatly surpassing that of Ishida Gin's. Duke was previously part of the U-17 French team, where he was known as the Destroyer, up until two years ago. Byoudouin had saved Duke's younger sister from a collapsing roof of a building just before a major group league match in France at the time, where Duke would be his opponent. Unable to play properly due to his injuries, Byoudouin lost to Duke. Indebted to Byoudouin for saving his sister's life, Duke immediately jumped ship to join the U-17 Japanese team following the match. Duke is a generally a pleasant guy, referring to Byoudouin as "boss", and always lightly smiling with his eyes closed like Fuji. Most of the time, Duke appears laid back and seems to have a beer belly. In reality, when Duke flexes, he easily tears through his clothes and is shown to have a lot of muscle mass for his age. Despite this, Duke likes to hit soft shots just as much as his power shots. He is portrayed by Keisuke Ōkubo in the musicals.

The story of the OVA series tells the continuation of the 13-episode TV anime in 2012, setting in the Japanese U-17 (under 17) High School Representatives Selection Camp.
