Mikuriya Akeno

An elite employee at Atori Inc.

She's foul-mouthed and often arrogant, but is a capable woman who's in charge of a whole branch despite her youth.
She won't hesitate to skirt the law for the purpose of achieving her goals, and most problems that arise she can simply destroy, through either money or her connections.
She interacts with Riku a great deal and tends to talk down to her, but since Riku kind of acts the same way, they get along fine.
