Airi used to be a member of the idol group QT. She was a popular idol that appeared on many variety shows. Due to her talent working in television, her agency urged her to stop being an idol and to become a TV personality instead. She rejected this offer, resulting in her quitting the group.

Airi seemingly gave up her dream of being an idol, even insulting Minori and saying she has no chance at becoming an idol, but was reinvigorated by her determination to reach her dream, thus agreeing to train Minori and join MORE MORE JUMP! with Haruka and Airi's former rival Shizuku.

Airi is strong-minded and comes across as pushy to some. According to Minori, she's strict but reliable. She is very protective of her friends and family, and hates bullies. She was more tomboyish as a child, though that was frequently shot down by her mother. To this day, Airi still manages to retain her headstrong attitude.

She would frequently dote on her past, bitter of how the industries she went to ended up trying to use her as a TV personality and disregard her idol activities completely. When she would do this, she'd become snappy and irrational to those who would confront her about her attitude, insulting them, only to feel guilty afterwards.
