Voiced by Ray Chase

Roy is an upstanding, thoughtful, and idealistic young man who repeatedly shows a desire to help and support others, shown in his interaction with Guinivere and his friend since youth, Lilina. While he would prefer to avoid blood-shed – a fact reflected in his interaction with Guinivere and his tactical efforts to conserve his soldiers – he maintains a strong resolve to see peace return to Elibe. Unlike most young protagonists, however, he is perceptive and cunning for his age – he tricks a traitorous Lycian vassal into exposing himself, deciphers that the bard Elffin is more than he seems (though he does not pursue the truth against Elffin's will), and often reacts calmly and tactically to disturbing news. He has red hair and blue eyes. In a support conversation between Lillina and Cecilia, it is revealed that Roy has an inferiority complex and the reason why he picked up a sword despite his teacher using magic.
