Typical female voice. A mezzo soprano, and a big tsundere.

Airi Momoi is a second-year student at Miyamasuzaka Girls Academy. She is a member of the idol group MORE MORE JUMP!

Airi is strong-minded and comes across as pushy to some. According to Minori, she is 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. Airi retains some of her headstrong attitude, though cares greatly for her friends as well as her siblings, taking a sisterly role with both.
