Hysteria was Claymore No. 1 during her generation, and one of the eight most powerful No. 1 Claymores of all time. She became known as "Hysteria the Elegant" Hysteria is a beautiful young woman with long, straight, pale hair pulled into a partial ponytail. She has four braids—two in front forming her bangs, and two incorporated into the ponytail. She has silver eyes and wears the standard uniform. Despite her calm and composed demeanor, Hysteria seems to hold herself in very high esteem, being impatient and easily offended when she is not given the attention that she believes she deserves. This is shown when she grows irritated at Miria's hesitance to reveal her forgotten name and when Miria becomes sidetracked during their battle, warning the younger warrior thrice that she hated being ignored above all else. She is also extremely proud of her rare, nearly unmatched speed; as such, she became extremely upset when Miria, using the combined Yoki of her comrades, became so fast that she could no longer keep up. Her arrogance may have been the reason why she, despite being on the verge of Awakening, never sent her Black Card to anyone. She subsequently resisted execution at the hands of her fellow warriors, choosing to slaughter them instead. She also had an obsession with aesthetics, which proved to be her undoing; Miria defeated her using a "filthy" strategy that she couldn't even begin to fathom using. Hysteria's arrogance and pride is what ultimately led to her demise.
