Hakase Shinonome

An incredibly brilliant but youthful scientist, this snack-loving shark enthusiast spends her time tinkering with her creation, Nano Shinonome. She frequently installs bizarre, unintended upgrades into Nano’s body, ranging from swiss roll dispensers to weaponry, often without the android even realizing it. Despite Nano’s repeated protests, the scientist refuses to remove the large, charming wind-up key from her companion's back, prioritizing aesthetic cuteness over practical design.
