Ryouta Takei

Ryota Takei is Aiba's classmate.

When in Shinjuku to test if their data body is capable of freely walking through the Real World, Aiba meets Ryota and Sakura Fujisaki. Ryota rhetorically asks if Aiba was in a deserted island during the last days, and is unable to remember which country Aiba has supposedly been too. Ryota is impressed after learning Aiba became a cyber sleuth, and envies his friend for being able to skip classes. Ryota has a crush on Sakura and eventually successfully asks her out, only for Nokia Shiramine to talk her into dumping him a day later due to her being able to get way better guys than him.
