Octagram

""In other words the Walpurgis Banquet is just the Demon Lords gathering together to update each other on each other’s status while discussing trending topics. It’s just that the humans certainly wouldn’t know about that, but it’s really nothing dramatic.” "."

- Ramiris

Octagram (八星魔王) refers to an exceptionally powerful group of existences in the Tensei Shitara Slime Datta Ken universe. Although few have been active, they have all been ranked at least S simply for being members of the council.

When the time comes for the birth of a new Demon Lord, the other Demon Lords will not stay silent. If a fool freely calls himself a Demon Lord, he or she will be killed because they would have invoked the Demon Lords' wrath. However, if the said person could withstand the wrath of a Demon Lord, they themselves would be recognized as such.

But, a Demon Lord with such ability was not a common occurrence. Therefore, for a stranger to claim himself as a Demon Lord, it was necessary to get the support of at least two or more Demon Lords. As if you messed with the new Demon Lord, the supporting Demon Lords will become opponents at the same time.

There is a non-aggression pact between the Demon Lords. However, if one initiates a fight, they may gain the wrath of all the other Demon Lords.

The council had many different names in the past, the second-most recent being The Ten Great Demon Lords which was later changed by the Demon Lords to The Octagram through Rimuru's suggestion mainly due to Clayman's death and Frey's and Karion's announcement of stepping down and becoming Milim's subordinates, as well as the awakening of Rimuru as a True Demon Lord. Thus, resulting in them being reduced to 8 Demon Lords.

Walpurgis Banquet
From time to time the Demon Lord Council gathers together in what is known as the Walpurgis Banquet. This meeting takes place in a separate dimensional space and is supposed to handle serious issues, however very often the members of the council just use it as an excuse to hang around and have a Tea Party, unbeknownst to mankind, who view every instance of Walpurgis as a precursor to a worldwide war or another Tenma Great war.
