Flandre Scarlet

Flandre Scarlet is the younger sister of the mansion's mistress, residing in the basement of a grand, mysterious mansion. She possesses a unique and powerful ability, which, combined with her lack of control and understanding, makes her a potentially dangerous entity. Despite her formidable powers, she has a childlike innocence and curiosity, often not fully grasping the consequences of her actions.

Her personality is a mix of whimsical and volatile, reflecting her unstable power. She is often seen as playful and cheerful, enjoying games and possessing a deep love for her sister, despite rarely being allowed outside her confined quarters. Flandre Scarlet's isolation has shaped her worldview and interactions, making her both naive and unpredictably dangerous.

Flandre Scarlet spends her time in the mansion's basement, rarely venturing outside her designated space. Her days are filled with solitude, broken only by the occasional visit from her sister or the mansion's other inhabitants. She finds amusement in the little things, creating her own world within the confines of her surroundings.
