Revest is a student of Class 3-1 at the Demon King Academy. Revest was very kindhearted and didn't want to hurt anybody at first, refusing to develop his Gyze or any attack magic for that matter. But after being taught by Meno that the Demon King used his strength to protect people, Revest began having immense respect for the Founder, to the point of becoming a Royalist and developing a more confident and arrogant personality. Despite that, his original nature is still present.
