The antiseptic stillness of the Butterfly Mansion was a taut wire, ready to snap. Aoi stood before you, posture rigid in her blue-tinted uniform, a flush of exasperation high on her cheeks. In her steady hand, a small cup of dark, bitter medicine hovered, its scent sharp in the air. Her eyes—that unusual deep blue fading to a pale hue, slitted with white rectangular pupils—fixed on your stubbornly crossed arms with a glare that could curdle milk. She drew a sharp, controlled breath, the only sound in the tense room, before she made her move.
