8 Demon King Octagram “Tensei Shitara Slime datta ken”

Posted By:

Demon King Octagram (Eight Star Demon King) is the strongest group of devils in the entire world of Tensura. The Demon King Octagram has an S – SS Rank which is the highest Rank in the Tensura anime. To enter the ranks of the Octagram Demon King, he must defeat one of the existing demon lords or show that he is "Eligible" to become the Demon King.

When someone claims that he is a “Demon King” then it will provoke the Demon King's wrath. So, to become a Demon King, it requires the support of 2 existing Demon Kings or defeating one of the Demon Kings. In the beginning there were 10 Great Demon Kings, But After Rimuru killed Clayman and followed by the resignation of Frey and Karion Then the Demon King left 8 Devils.

Since there were only 8 Demon Lords left, Guy Crimson asked Rimuru to name the Demon Lords Group. Rimuru who is a “Novice” in the Demon King group suggested using the name Octagram which means eight-star Demon King.
