Aaya Saitou

An outgoing and energetic classmate, this spirited girl lives with her brother and often takes charge during group activities. While she appears to be a curious friend to Kiiko, frequently initiating scientific experiments to test Kiiko's unique abilities, her true motivations are much more romantic. Her deep affection is hidden behind these playful tests, such as the time she used intertwined wire stars to challenge Kiiko's powers, masking a heartfelt crush under the guise of academic curiosity.
