“Rentarou Aijou...I have fallen for you. I would like you to go out with me. I would seem that I have much to gain from being in love with you. I would like to spend much more "significant" time with you...That I still have yet to discover.” Nano always thinks that relationships are meaningless and would be wasting time if she does it. She is obsessed with solving a problem in the most efficient way possible no matter what. She is intelligent, calm, composed and almost stoic. She often comes across as a cold person, earning herself the epithet A.I. girl, but she does have feelings.Nano seems to have a fairly close relationship with Shizuka, accompanying her to buy books. She's the one who sees the most. Nano always saves Shizuka while gust of wind blows her petite body away. It has been implied that Nano saw Shizuka more than just a friend, as she briefly tried to admit that she loved her in Episode 19/Chapiters 38 and 184. Though, it can just be a joke with the fact that the two of them are very close friends.Nano's birthday, March 14th.
