A Dragon Slayer belonging to the wizard guild "Sabertooth," known by the epithet "Shadow Dragon Rogue." Like Sting, he is a Third Generation Dragon Slayer with Lacrima implanted in his body, and together they are hailed as the "Twin Dragons." Extremely taciturn, calm, and collected. While he appears cold at first glance, he is deeply compassionate and kind at heart, doting on his partner Frosch (sometimes to the point of overprotectiveness).

Sting Eucliffe's partner, an Exceed (a creature resembling a cat) who is always seen with him. He uses polite language, addressing superiors and comrades with honorifics like "-kun" or "-san."

Rogue Cheney's partner Exceed. Always wears a pink frog costume (he used to believe he was a frog, and after being shocked to learn he was a cat, he has worn the suit ever since). His catchphrase is "Fro thinks so too!" and he speaks at a uniquely slow pace.
