She is a 1st year, class 4 student at Ohananomitsu High School. Tall and slender with thigh-length white-blue hair that has bangs on the right side and sharp red eyes. Nano is practical to a fault, obsessed with solving a problem in the most efficient way possible no matter what. She can break this super efficiency, but only if really convinced. She acts almost robot like, speaking with very good vocabulary and not usually making mistakes. She does subtly get embarrassed occasionally though.
