History
The Demon Realm is a only one of a handful of sub-dimensions within the universe. Others, such as the Room of Spirit and Time, or the pocket dwelling within the Pendulum Room. They each were created for a unique purpose, and generally by a higher power than that of mortals. In this case, the Demon Realm was originally devised as a prison to hold the first of the Kaioshin to become disillusioned with his goals and fall into the temptation of abusing his power for personal gain. The others could not allow him to simply wander the known, young cosmos and create untold damage, and as such banded together with the first Kaio under the command of the Dai Kaio to not only create a dimension to hold a being of Supreme Kai strength, but to prevent any future Kaioshin from trying to free him.

The result was a unique key of energy required to weaken the barrier set up to contain the prisoner and another Kaioshins presence at the weakened barrier to bring it down entirely, in that order. Done any other way, or without the co-operation of all five Kaio, it would be impossible to open up the barrier over the gateway into the dimension crafted. Weakened but not exhausted, the remaining four Kaioshin tracked down their fallen member and promptly engaged him in combat long enough to banish him through the gate way and thereafter seal it before he could recover. Despite the bleak and harsh surroundings, the black magic sucking at his ki(chi), and the thin oxygen, the fallen Kaioshin was able to recover enough to endure and begin making a living in his prison, though not without much loathing.

Over the millennium, his emotions and the magic of the prison warped his physical body from the graceful form of a Kaioshin into the brutal and vicious form of a demonic creature. Thus, when this was discovered some generations later, the title of "Fallen Prison" slowly changed to be "Demons Housing" and eventually from that into "Demon Realm" as the number of Kaioshin who would fall to temptation and be exiled there increased and likewise warped them.

Some several hundred million years later, yet a few million years prior to Majin Buus attack on Other World, the then- South Kaioshin Dabura fell from grace like the dozens of others before him and was likewise sealed away in the Demon Realm. Unlike the others before him, he had actually given this much thought and study before making his rebellion known. His exile was one of the most devastating to the Dai Kaioshin, however, who had much faith in the former South Kaioshin and had shared many pieces of knowledge with him. Around that point in time, one of the last things Dabura was able to accomplish prior to exile would be to see that new, non-Kaioshinic beings be sent to the Demon Realm as greater punishment.
