Sakura Adachi is a first-year high school student. She tends to skip class and that's why the rest of the students see her as a delinquent, but she just doesn't like to be around people. One day, Hougetsu Shimamura, a girl from her class, finds her on the second floor of the gym with the intention of skipping class too. Strangely, Sakura becomes really attached to Hougetsu and wants to be the closest person to her.

Adachi had an extremely introverted personality. Before meeting Shimamura, she never had someone whom she can call a friend. Adachi was said to be cold toward other people and didn't attempt to make friends with other people in the past.

She is also a generally very jealous person towards Shimamura when she is together with her friends and as a consequence usually ends up running away.

She is left-handed.
