Heaven is the ethereal realm of Angels. It is where souls go after their departure from life. But, unlike its infernal counterpart, Hell, Heaven is purportedly for the souls who are "good" and "redeemed", although the origin of Heaven and its native inhabitants has yet to be revealed. The landscape is radically different from Hell and has an entirely different attitude. Heaven can be seen in the Pride Ring's red sky next to the satanic star moon. At a distance, it appears to be a white planet with several rings around it and surrounded by wing-like clouds. At the surface, its atmosphere features clear skies filled with brilliant rays of light, while its terrain appears to be extensive fields of cloud. Sealed by a giant golden gate, Heaven is a blistering paradise for those who were pure of good, allowing the souls to enjoy the luxury of everything opposite of Hell, and their forms were pure, guiding those who've been blessed with following the best interest of Heaven. However, deep inside, Heaven is a dystopia where citizens are completely oblivious to the Exorcists descending to Hell annually and reap various demons in an event known as the Extermination in order to prevent an uprising, claiming it's to curb Hell's overpopulation problem. Even when Adam and Lute outright inadvertently exposes the truth of the Extermination, many angels would try to deny their roles and turn a blind eye towards the event. However, many angels were horrified this event was allowed even though they were Sinner demons. Aside from their roles in the afterlife, Heaven and Hell have a very hostile relationship in their roles with each other. Hell was created after Lucifer Morningstar and Lilith brought free will to humanity and evil entered Earth. After Lilith arrived in Hell, she thrived and allowed her to increase the powers of the Demons as more human souls arrive after committing sin. With Hell's power increasing, Sera, the High Seraphim of Heaven, allowed the Extermination to happen under Adam's authority.
