Gieve stands out as the series' true neutral—he never really picks a side in any of the major conflicts, which sets him apart from basically everyone else. He bills himself as a musician, but that's selling himself short. He's honestly a jack-of-all-trades kind of guy, picking up whatever skills he needs. Combat-wise, he's the most adaptable fighter in the whole series, equally comfortable with a sword, bow, or lance. On top of that, he claims he can play literally any instrument you throw at him.
In the OVA, Gieve's known for breaking the fourth wall—when he's alone, he'll turn and address the audience directly, narrating his thoughts on whatever's happening in the story. Though honestly, it's hard to tell if he's actually trying to inform the viewers or just loves hearing himself talk. Fans often lean toward the latter.
