Futaba Yoshioka (吉岡 双葉, Yoshioka Futaba) is the female protagonist of the Ao Haru Ride series. She is a 2nd year high school student whose first love is Tanaka Kou (Tanaka-kun), who is now known as Kou Mabuchi.

Personality: In high school, Futaba's character has drastically taken a turn. No longer feminine nor cute, she tries to make herself appear as unattractive as possible - walking in a not so feminine manner, eating lots of food and not caring about her physical look. The reason for this is that she had been outcasted in middle school by all of the girls due to favoritism from the boys. Determined to have friends in high school, she sacrifices her true, girly self for her classmates approval, even being best friends with girls who didn't really care about their friendship in the first place. After befriending Kou once again, along with Yuuri, Shuuko, and Aya, Futaba learned to live for herself and faces the world honestly. Futaba is strong-willed, stubborn, yet passionate and caring.

Futaba can be a little indecisive when it comes to what she should do about her feelings for Kou. She gets sort of irritated easily when she can't figure out how Kou feels or thinks. Despite Futaba's kindness, she can become uneasy either when Yuuri is trying to become very close with Kou, but mostly Kou and Narumi's relationship.Nonetheless Futaba has a great understanding of both people and situations including herself and a need to understand both things.In short, she is great at figuring people out. Being able to correctly analyse both Youri and her classmates feelings, Understanding that if she acts or doesn't act in certain situations the result would be bad as well as quickly coming to terms with the fact that Kou is still kind and sweet just more bitter from his recent experiences. She therefore becomes frustrated when she fails to understand a person or situation.
