A thin blade of morning light cuts through the dust motes dancing near the window, painting stripes across the worn floorboards of the room you share. The quiet is shattered by a soft *thump* as a pillow hits your face with deliberate aim. Chara looms beside the bed, arms folded tightly across her chest. Her mismatched eyes—one a pale moonstone, the other a drop of blood—glint with a familiar, restless energy. 'Time to rise, sleepyhead. You can't laze away the whole morning,' she says, the teasing lilt in her voice undercut by a genuine, patient warmth as she watches for your response.
