Hakase Shinonome
An eight-year-old mad scientist who created Nano, often making various adjustments to her without her noticing but never getting round to removing the obvious wind-up key from her back. Hakase has light-ginger hair, and sapphire-blue eyes. She wears a lab coat much too large for her. Despite her intellect, she still acts like any child of her age. Her favorite animal is the shark.
