In The Lesser Key of Solomon, Balam (also Balaam, Balan) is the fifty-first demonic spirit listed in the Ars Goetia. He is a powerful great king of Hell (to some authors a duke or a prince) with forty legions of demons under his command. He is depicted with three heads; one of a man, one of a bull and one of a ram. He has the tail of a serpent, eyes of flame, rides nude upon a bear, carries a hawk on his fist and speaks in a hoarse voice.
The Demon of avarice, idol worship and immorality. Balam is a nocturnal demon who is most powerful during the month of December. Balam can only be summoned when the sun is in Sagittarius; when he arrives, he will have with him four kings and their entourage. Balam had the ability of limited precognition, mortals would worship and entreat him for power or glimpses of the future. He was also capable of shapeshifting.
When summoned, he speaks of all things past, present and future, teaches man to be witty and wise and can turn a person invisible. He is an excellent teacher of the subtle art of cunning, and he imparts wit and finesse to whoever queries him on these matter. He was listed as one of the eighteen demons who possessed Sister Jeanne des Anges, in Loudun, France, in 1634.
In the Bible, Balaam was a wizard who tried to curse the Israelites, but his curses turned to blessings instead, much to his dismay.
Balam is the demon lord who has taken control of Shibuya, having brainwashed the residents into worshiping him as their god. The protagonist can fight him if his intelligence is 7 or higher. Defeating him results in obtaining the Moon Pillar.
Balam is the boss of the World of Sloth. He is found in floor B3. While searching for an exit, the protagonist withstood the other students being forced to dig until they died of exhaustion. There are 5 passages in the last underground floor, and each passage is being opened by a student, while every Full Moon one slot can be added to the passage, one of which leads to Balam. When defeated, if the passages were dug up enough, it drops the "Ring of Diligence." If he is defeated before the passages are fully dug up, the Ring of Diligence appears in another passage.
