Heaven is the lair of the Chief God and her subordinate divinities, valkyries, and angels. It does not seem to function as an afterlife for the benefit of departed souls, but rather as the private dimension of the celestial gods. Impervious to attack by mortals or monsters, Heaven shares many of the attributes of "Spirit Realms" as described in the Mamono Realm Traveller's Guide.
Although it is not explicitly remarked, Heaven is described as the dwelling place of multiple greater divinities, so it seems possible that "neutral" gods like Ares and Eros do reside there. Conversely, corrupted divinities like the Fallen God and Poseidon are categorically banished from the realm.
It is not clear whether the Monster Girl Encyclopedia world's Heaven functions as an afterlife for mortal souls. Although such souls are explicitly attested - since female souls can be monsterized into ghosts and male souls can be captured by will-o-the-wisps - the materials on Heaven make no mention of them.
Book Information[edit]
Realm of Heaven (Early settings info)[edit]
The world ruled by the divinities. It is said to exist far above the sky, and it's supposed to be a wondrous and beautiful place. In front of the palaces where the gods who are the greater divinities live, the lesser divinities who are servants of a particular god have castle towns, and they number as many as the gods themselves. Only divinities dwell within the realm of heaven, and since only the divinities themselves know the means of traveling between the realm of heaven and the human world, humans and monsters are unable to invade it. However, on rare occasions, lesser divinities who were converted into monsters while visiting the human realm do return there. In that case, it is said that the lesser divinity is banished from the realm of heaven and dropped into the human world.
