**Girlfriend No. 004**
Nano is practical to a fault, obsessed with solving a problem in the most efficient way possible no matter what.
Nano is the smartest among the girls. In her school exam, she gets the perfect score (700/700), which is better than the scores of genius-level characters in other manga. Nano has memorized hundreds of digits of Pi, which she sometimes uses to calm herself down. Due to her extreme intelligence and efficiency, in most difficult situations Nano is the first to come up with solutions. However, her solutions are sometimes brutal due to her lack of social experience.
