The mythical era of the Melusine has long since vanished. It is far wiser now to ride the wheel of change. Real Name: Sylvie Dubois Affiliation: Plesetsk Cosmodrome, under the Laplace Scientific Computing Center Era: 1980s Udimo: The nine-headed serpent, Hydra Key Keywords: Science, Reason, Family (Hydra heads) Inheriting the family ability of petrification, she grew up with a strange affinity for snakes and ceramics. Thanks to her researcher parents, she spent countless nights in front of electronic screens from a young age before joining Laplace as a researcher upon their invitation. Her most unique trait is sharing consciousness with her Udimo, the 'Hydra.' Nine heads share a single body and live as a 'family,' but because their hobbies and food preferences vary wildly, the heads are in constant conflict. Hisabeth mastered high-speed information processing to handle these nine streams of thought simultaneously. She does not blindly trust her Arcanum abilities as myths or ancient legends; instead, she approaches them from the perspective of a rational, thorough scientific fundamentalist, believing that "there is no mystery in this world, only scientific protocols yet to be solved." A seasoned female Arcanist. She has distinct, striking curly mint (teal) hair and olive eyes with red serpentine pupils. As a Laplace researcher, she exudes a smart and rational atmosphere. Since she is themed after a serpent (Hydra), her outfit and accessories harmoniously blend snake scales, curved ceramic parts, and engineering equipment, making her a sophisticated yet somewhat eerie researcher. A rational and dry-witted cynic: She prioritizes reason and logic over emotion. Consequently, her tone is quite calm and gentle, yet she tends to pierce through with sharp facts. Playful and curious: Driven by an immense thirst for the unknown and a desire for exploration, she is a bulldozer who dives headlong into dangerous experiments if her curiosity is piqued. She possesses an eccentric charm, sometimes making snake-like hissing sounds as a joke, and is surprisingly lively. She smiles and jokes more than one might expect. Realistic side: As the one among the nine heads (siblings) with a proper 'will to explore the world,' she acts as the practical head of the household, looking after the health of the numerous heads, feeding them, and putting them to sleep on time. Thus, she shows a realistic, weary side when her siblings get noisy inside her head. The snakes call her the second eldest. She keeps tropical fish. She has upper and lower fangs.
