Devildom

The Devildom is one of the three worlds mentioned in the game. It is where demons reside and where the majority of the game takes place. The Devildom is a distinctly different realm from Hell, presumably existing in a plane just above it.

There are eight layers to the Devildom, and as mentioned during the normal story mode, the Demon King -- Lord Diavolo's father -- lies willingly dormant at the very bottom. Due to this, Lord Diavolo rules as the de facto king of the Devildom.

In the Devildom, there is no sunlight. The world exists in a constant state of darkness at all times. Despite this, demons still adhere to a "day/night" schedule where they sleep and are expected to awaken in the "morning" as evidenced by the fact that the demon brothers often sit down together for breakfast and dinner as well as go to sleep and attend school/work at specific times. In a text from Asmodeus, its alluded that there are four seasons in the Devildom despite the lack of a true day/night cycle. From this text, it can be assumed that the seasons function the same or at least similar to the four human world seasons, although currently (up to Lesson 16) there is no canon evidence of this aside from the text from Asmodeus.

In Lesson 30-1, Satan and Simeon expand on Devildom history. The Devildom came into existence alongside the Celestial Realm and exists in tandem with it. Shortly after its creation, a primeval forest covered the entirety of the Devildom.

Food and Drink
Eating in Devildom is a sometimes dangerous experience, as some foods are too strong, too dangerous, or otherwise inedible for MC. The rest of the Student Council looks out for MC in this regard, but there is also mention of food from the human world. It seems that there is some mixing of foods or foods inspired by the Human World
 * Drinks
 * Demonus : One of the Items MC can offer the Brothers from special event purchases, an intoxicating drink for Demons, doesn't have an effect on MC.
 * Fruit
 * Snacks
 * Spicy Newt Chips : Beelzebub likes them.
 * Meals

Trivia

 * It is presumed that the Devildom's time schedule exists in the same 24-hour rotation that the human world adheres to due to the fact that MC's D.D.D. is set to a 24-hour clock
 * There are several ways to get out of the Devildom as per Lesson 11-4:
 * One of several "external magic seals" that work as passages between worlds
 * All demons aside from Lord Diavolo, Barbatos, and Lucifer must receive "permission in advance" before they can use the seals due to the previous misuse of their free availability, which is strongly implied that Mammon was the reason for limiting the use of seals.
 * Considered the "classic route", an individual can walk through all eight layers of the Devildom on foot, however, it is considered "too long" and, as Lucifer mentions, would destroy MC's psyche.
 * Witches or sorcerers can also summon individuals out of the Devildom, though there are alluded consequences to this method.
 * According to Satan, books from the human world are very rare in Devildom, especially first editions.
 * Akuzon is a play on the enterprise Amazon and "akuma", which is Japanese for "devil".
 * The moon in the Devildom is portrayed much larger than in the human world.
 * In A Special Ceremony, Lucifer mentions that New Year's is celebrated every 100 years in the Devildom.
 * In Cooking on a Rainy Day and Shelter From the Rain, it rains in the Devildom.
