Sakagami Ryouta

Sakagami is also in the management of "Birdie," but he is young and still new to management, and therefore is working as Matoba's assistant to gain experience. He is good with computers, and does a lot of the computer work and takes care of the peripheral equipment for the group.

He is You's charge, and since they share an interest in websurfing, they have a small friendship unrelated to work, and Sakagami tries to be helpful for You.
