Alex is one of the people who cleared an Unnamed VR game before the start of Gemblade. During the events of that game, he had his mind taken over by a program similar to Wolf, but this one broke his mind, and caused him to temporarily descend into madness. he has since disappeared, and has yet to appear, but even if he does, whose to say his mind is truly whole?

in  the first encounter with Edward, the two of them clashed briefly, Alex using some sort of acceleration power to overwhelm Edward completely before Alex disappeared.
