Aoi Tsumura

Aoi is the second younger sister of Ikuto and the third child of the Tsumura family. Aoi is talented at volleyball and has been scouted by top schools, though Aoi declines the offers due to the expensive tuition. Since Aoi's sport takes up her time, she does not help around the house as much as Ikuto or Honoka do, but she steps up when needed. Aoi prefers clothes that are easy to move in and Ikuto often makes often blue-colored clothes for her, which is Aoi's favorite color and the meaning of her name.
