Nano Shinonome

Nano Shinonome (東雲 なの, Shinonome Nano) is a humanoid android created by Professor Shinonome (or simply Hakase), who lives with her and Sakamoto and manages the Shinonome household. She is constantly being upgraded by Hakase without prior knowledge or approval, which is a running gag. This leads to strange situations, that Nano worries might reveal her identity as a robot to others, particularly her classmates. She lives in the Shinonome Lab.
