Nao Serizawa (芹沢 尚 Serizawa Nao) was the third year junior high student who debuted in the second volume of the light novel High☆Speed! written by Kōji Ōji.[1] He was a manager of the swimming club.


He has long grey hair with bangs, yellowish-green eyes and is relatively tall and is usually shown with a kind smile on his face.


Nao is somewhat like Makoto, inferring to their kind nature and such. For one thing, they even share the same eyes(more droopy and kind-looking). Being somewhat like a mother to them, he has a gentle and soothing personality. Nao is also extremely empathetic, prior-known to understand what Asahi is going through when Asahi says to Nao that what [1]Natsuya said about their relay. He also is a good listener, letting the person he's talking to spill out to him.


Nao Serizawa was a third year at Iwatobi Junior High School while Makoto and Haruka were freshmen. He was a manager of the swimming club and was responsible for giving guidance to the first years.
