Kugoku

"You know what the funny thing is? Despite being sealed away in this desert for centuries, longer than I can count, I don't hate humans. Infact, I kinda deserved that. Really. I did sorta kill alot of people after going haywire, but, y'know, semantics. I mean, with a flick of my finger, I can wreck your entire town, would you let me stay at your house? Please, you'd put me a on leash, I'd escape, and everyone'd be dead. Kinda my fault I ended up here, now that I think about it..."

- Kugoku's towards humans Kugoku (九獄, Nine Prisons) is a monstrous Demon of immeasurable power that is believed to be sealed away within Desierto, in a sense that he cannot leave the endless desert no matter how hard he tries, as if it is a "prison" of sorts. He was previously a destructive force that was a failed attempting at mimicking the Demons of Zeref by Mages, instead creating a self-aware monster that immediately betrayed them.

Kugoku gained infamy in his short, but well known rampage that lasted one week, resulting in a large portion of Desierto being destroyed, prior to being turned to his prison. He became known by titles such as Fox (狐, Kitsune), Inari (稲荷, Inari) and Gizensha (偽善者, Fox in Lamb's Skin), by the people who he fought and sealed him, but was forgotten centuries later by the world, due to no giving up on trying to escape.
