Judeau is the kind and keenly observant Smart Guy of the Band, who has an unrequited crush on Casca. Yet he holds no grudge towards Guts for having won Casca's affections and even helps them get together. He used to be part of a travelling circus, which is how he learned to be a jack of all trades and absorbed a great deal of useful knowledge. He uses throwing knives with deadly accuracy, and is also a cunning tactician in combat.
