Devildom Night View.png

The Devildom is one of the three worlds that exist 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 KingLord 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, though according to Diavolo there are different degrees of darkness depending on the time. 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.

The sky and its constellations are different from the human world's. In the Star-Crossed Lovers Devilgram, an autumn sky constellation is mentioned — the Pool of the Abyss — along with the myth associated with it. One star represents a beast, and another the maiden that was carried off by it. The nebula below the two stars symbolizes the pool created by her tears as she yearned to see her beloved.

In Lesson 47-9, Belphegor mentions "Devildom script", meaning the Devildom likely has their own language.

It is stated in Season 3 that the Devildom once went to war with the Celestial Realm. It is unclear what the outcome of this war was, but this war ended long before the Great Celestial War.

Leaving the Devildom

There are several ways to leave the Devildom, as per Lesson 11-4. One way is making use of 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. This is due to the previous misuse of their free availability. It is strongly implied that Mammon was the perpetrator.

Another method, considered the "classic route", involves an individual walking 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.



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.


The Devildom is currently ruled by Lord Diavolo, but was previously ruled by his father, the Demon King. Diavolo stated in Lesson 7-10 that he had not seen his father in several hundred years, as he'd lost interest in ruling and was slumbering in the lowermost layer of the Devildom. Diavolo's father was still awake when the brothers fell, as he assigned them their titles as the avatars of sin.

Lucifer spoke in Lesson 7-10 of another Demon King who ruled prior to Diavolo's father. Nothing is currently known about this prior king, save that his crown is displayed in the Demon Lord's Castle.


Halloween is considered a very important holiday in the Devildom, as it also being a celebration of Diavolo's birthday. Celebrations of this event last for three days.

Helldown Day
Helldown Day is mentioned in the chats Helldown Day 1, 2, and 3. Helldown Day was created in the Devildom as a way to protect the balance of the three worlds. During the holiday, all demons must refrain from using their magic. The use of magical items is also prohibited.

Jill's Day
This holiday is mentioned in the Devilgram The Rare Flower. According to Lucifer, it is named after a woman who sold her soul to a demon. To celebrate, a tea party is hosted at the Demon Lord's Castle and Diavolo is presented with extravagant gifts.

New Years
In the Pop Quiz A Special Ceremony, Lucifer mentioned that New Years celebrations happen every 100 years in the Devildom.

Sir Black's Anniversary
This holiday is mentioned in the Devilgram The Rare Flower. It takes place in the month after Jill's Day and can also be celebrated with a tea party and gifts.

In the Pop Quiz You're A Gem, it is shown that Thanksgiving in the Devildom involves the raining down of magical gemstones from the sky. Handling these gems causes both demons and angels to enter an extremely positive mood and express what they are thankful for. Giving these gems as gifts to loved ones is customary, and each colored gemstone has its own unique meaning. As Diavolo explained to MC, a special kind of golden gemstone only rains down around high-ranking demons.


Grimm coin

The currency used in the Devildom is called Grimm. Grimm exists in the form of gold coins with a skull relief or brown banknotes. The player also uses this currency for various in-game expenses such as upgrading cards or unlocking spaces in Devil's Tree. Players can obtain Grimm by clearing battle stages or sending characters to work at :D JOBS. Tasks and Pop Quiz events also often include Grimm as rewards.

Asmodeus Devildom Text.PNG

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 the Devilgram Shelter From the Rain, it rains in Devildom similar to the Human World. According to the Devilgram Cooking on a Rainy Day, sometimes the rain can appear black depending on the weather conditions. However, in the chat Suspicious Weather, there's acidic rain which Lucifer warns that humans should avoid.
