Nao Tachibana

One of Yuuya's childhood friends and a second-year student who hates dressing up in girlish clothes and instead always dresses up in a cheering outfit instead (in reality, she thinks that a "girlish" look doesn't fit her). Because of her appearance, Yuuya mistook her for a boy when they were younger. The length of her hachimaki (the headband) is 10 meters, and Yuuya often accidentally stomps on it and falls on Nao. She is also quite naive.
