Demon Realm (SSJJ)

The Demon Realm is the home realm of Towa and Mira, and former kingdom Dabura. It is located at the very tip of the universe and is describe to be a physical plane opposite to the universe.

Dark Energy
The Demon Realm is a popular location of Dark energy as it is used to create Dark Potaras, Dark Evolutions, Dark Masks, and even Darkness forms for Demons. Normally the seal on the realm prevents Dark Energy from being used outside the realm, but several inventions like the Dark Potaras enables them to use the power and even corrupt the seal.

Deities
The Demon Realm is known for it's Demon Gods, Supreme Kais (Makaioshins), and Dark Guardians. For a long period of time; Naraku was the Demon Realm Supreme Kai and thus due to position being recognises as a legitimate Supreme Kai variant - he was able to stay fused. Like the Supreme Kai of Time; Demon Realm Supreme Kai's aren't linked to a god of destruction as the job isn't necessary in the Demon Realm.

Locations
Gierropa (ジアーロッパ; Jiāroppa) is home to massive wellspring of Dark Energy and is the most potent source of the energy in the entire realm. However, as of Age 946; the wellspring had been vastly damaged to overuse, and energy from Dark Shenron to restore the pool. Should the Dark Energy be destroyed - the Realm will collapse.

Trivia
