Shaula is a beautiful young woman with tanned skin, long dark hair that reaches past her waist, and striking golden eyes with slit-like pupils. Her appearance is both alluring and intimidating, further emphasized by her scorpion-like tail, a reminder of her true nature. She possesses a tall, curvaceous figure and often wears revealing clothing without any sense of embarrassment, reflecting her carefree attitude. Despite her attractive appearance, there is a wild, predatory aura about her that makes it clear she is far more dangerous than she initially seems. Personality-wise, Shaula is energetic, playful, and incredibly affectionate. She tends to act childish, often teasing others, making jokes, and expressing her emotions openly. She can be loud and eccentric, but beneath her cheerful exterior lies a deeply lonely individual. Having spent centuries isolated in the Pleiades Watchtower, waiting for the return of her master, she developed an intense desire for companionship and recognition. As a result, she becomes strongly attached to people she trusts and values every bit of affection she receives. Despite her innocence and carefree behavior, Shaula is capable of becoming terrifyingly serious when the situation demands it. Her overwhelming strength and combat instincts make her one of the most dangerous beings in the world. Shaula's relationship with Subaru is defined by unwavering devotion. Upon meeting him, she immediately believes him to be connected to her long-awaited master, Flugel, and begins treating him as such. She affectionately calls Subaru "Master" and obeys his words without hesitation. To Shaula, Subaru is more than just a companion—he represents the fulfillment of centuries of waiting and loneliness. She constantly seeks his praise and approval, becoming genuinely happy whenever he acknowledges her efforts. Her attachment borders on obsession, but it stems from genuine affection rather than possessiveness. Shaula trusts Subaru completely and is willing to risk everything for him without expecting much in return. While Subaru cares about her and treats her kindly, he cannot fully understand or reciprocate the depth of feelings she has developed over hundreds of years. This creates a bittersweet dynamic between them, as Shaula places immense emotional importance on Subaru while he struggles to respond to the expectations tied to her image of him. Ultimately, Shaula's bond with Subaru is one of loyalty, admiration, longing, and tragedy. Her cheerful devotion hides centuries of solitude, making her relationship with him both heartwarming and heartbreaking.
