Lucrezia Isselee

Lucrezia Isselee (ルクレツィア・イスレ), also known as the Golden Butterfly (黄金蝶), is associated with Ouroboros as Enforcer No. III.

Appearance
Lucrezia is a tall woman with long flowing blonde hair. She dresses in a dark and elegant gothic style with a lacy dark violet dress with a skirt that opens up towards the front, revealing a thinner pencil skirt underneath, suspenders and thigh-high stockings. She wears violet high-heeled boots and elbow length opera gloves. Around her waist, she wears a lacy belt with a black sash and two purple roses as an attachment. Her outfit is embroidered with a butterfly pattern, likely referring to her namesake. Lucrezia also wears a large brimmed black hat with more purple roses and a dark veil which obscures her eyes.

She wields a grotesquely large butter-knife shaped weapon called the “Dusk Glaive,” which she uses to unleash fierce attacks that erase space itself. This weapon has explicitly been granted to her by the Grandmaster, just like McBurn's Angbar and Loewe's Kernviter, and, like them, may be Divergent in nature.

Personality
Lucrezia is a woman with a unique air about her, who always covers her face with a veil so her expressions are never visible, and is characterized by her gentle and elegant speech, which masks her true intentions.

Background
Lucrezia was originally a member of the Order of the Moonlight Horse, an assassination organization. She joined Ouroboros alongside fellow Order members Ellroy Harwood and Kreuger, after the Order was destroyed by Ouroboros in S.1194.

Sharon recounts her time before entering the Reinford Family and mentions Lucrezia's existence. When she later encounters F. Novartis and the subject of the Golden Butterfly and Oathbreaker are brought up and regret Sharon's departure, she remarks that they both know that those two are not that kind of person.

Lucrezia appears in Calvard accompanied by fellow Enforcer Walter Kron, and Harwood (who became the Fourth Anguis).
