Although her name does not begin with an "I," the "Ai" from "Aiko" represents an "i" sound in Japanese, indirectly marking her as an "i." She is quite ditzy, scatterbrained and is prone to losing or misplacing her possessions, but she's also very nice, kind, and unbelievably cheerful, even in bad situations. Also, she looks almost exactly like Iori Yoshizuki, save for a mole under her left eye. Her uncanny resemblance to Iori causes Seto some complications when she is introduced three-quarters of a way through the manga. She, as well as Seto, falls in love with one another at a later point once they meet. Asou realizes this is a potential problem for Seto and decides to move away in order to keep Seto's and Iori's love intact.
