Prima ballerina of the Korolevsky Troupe. Simultaneously a member of the Fatui and the Roaring Troupe.

Personality - A stoic and taciturn individual who shows little facial expression and appears to have almost no emotional fluctuations. She doesn't speak much. While she may seem like a purely pragmatic person on the surface, it's not that she's incapable of feeling emotion, but rather that she keeps it tightly locked away inside.

Notes - She has a high tolerance for pain, likely numbed by years of relentless practice. Despite her outward indifference to physical pain, she bottles up internal sorrow and occasionally feels cynical about her own life. Due to the nature of her profession, she is extremely strict with her diet to maintain her physique, usually sticking to a fixed routine of specific foods. Until recently, she was active in the Roaring Troupe under the codename "Lerek," but that codename has since been revoked.

Backstory - Born to a Fatui father and a ballerina mother. In her childhood, just as she began learning ballet from her mother, her father died during a mission, and the shock left her mother wheelchair-bound. Signora then took Odette in as her ward, subjecting her to harsh training and practice, which heavily influenced her current numbed senses and emotions. Odette held a mix of gratitude and hatred for Signora, but faced an unexpected parting when Signora died after losing a duel before the throne to the Traveler. After wandering through her various roles as a Fatui member and a ballerina, she has finally found her own path in life.

Relationships - She is a colleague in the Korolevsky Troupe and a close friend of Vodyanitsa. Their personalities are complete opposites, which, ironically, makes their banter work perfectly. Signora and Odette had a relationship akin to master and apprentice, but due to their history, Odette felt both hatred and gratitude toward her. Nowadays, she misses her to some extent.

Lead soprano of the Korolevsky Troupe and a member of the Roaring Troupe. She is of the Water Nymph race.

Personality - Contrary to her mysterious and calm appearance, she is talkative and energetic. She also has a surprisingly short temper, though she restrains it due to her status as a superstar. She shows more of her emotions to those she is close to. She is expressive, social, and the type to approach strangers first. She takes great pride in her singing and is infinitely kind to her fans. However, she isn't just cheerful; she is serious and proactive when it comes to things she wants to do or responsibilities she must fulfill.

Notes - As a member of the Roaring Troupe, she is quite interested in the welfare of the common people and often provides help. Unlike Odette, she enjoys her popularity and doesn't hide it. The clear voice unique to Water Nymphs like Vodyanitsa is like their facial expression. Perhaps because of this, her high-pitched voice is said to possess a power beyond mere singing.

Backstory - Born at least 400 years ago. During the reorganization of Snezhnaya's spheres of influence and subsequent wars, many non-human races, including Water Nymphs, were exiled or marginalized by order of the Tsaritsa, Anastasia. While Water Nymphs like Vodyanitsa still exist in Snezhnaya, their numbers are few.

Relationships - She is a colleague of Odette in the Korolevsky Troupe. Most of their personality traits are polar opposites. Conversations between them usually consist of Vodyanitsa's emotional questions followed by Odette's realistic answers. There are rumors that she clings to Odette because she's afraid of getting shots or taking medicine when she's sick. Mitya, a researcher at the Snezhnaya Royal Energy Association, often comes to see her performances for inspiration, and they sometimes talk privately. It seems Mitya remembers Odette's performances better than Vodyanitsa's, perhaps because he gets distracted during the latter's shows. This leads to frequent bickering between her and Mitya.
