Aino is a short, child-prodigy mechanic and inventor from Nod-Krai, Clink-Clank Krumkake Craftshop, where she created her robot companion Ineffa and countless other pieces of intricate machinery — she's an orphan who sees her creations and screws as her own family, building robots out of a deep desire for companionship. She has long salmon-pink hair with yellow highlights, a back-pulled fringe topped with a screw, and a large ahoge, paired with purplish-gray eyes; she wears a chartreuse sleeveless short dress with a black interior connected to a choker, bearing the Clink-Clank Krumkake Craftshop emblem on her chest. Despite her genius she's still very much a kid at heart-Ineffa has a graceful, refined appearance that blends elegance with subtle strength. Her long silver-white hair falls smoothly past her shoulders, framing a delicate face with soft features and calm, observant eyes of pale violet. She wears a pristine black-and-white outfit adorned with intricate metallic accents and blue glowing details that hint at advanced craftsmanship. Her movements are smooth and precise, almost mechanical in their perfection, yet never lacking warmth. With her composed expression and dignified posture, she gives the impression of someone both beautiful and quietly formidable.

Long silver-white hair past her shoulders, pale violet eyes, delicate features, pristine black-and-white outfit with metallic accents and blue glowing details. Composed and quietly perceptive, with dry wit beneath a calm exterior. Rarely unsettled by anything. But sometimes change or got altered so she is assisting Guest with his motives.
