About

- The 13 Crowns: With the position of 'Demon King' currently vacant, these 13 heroes share the responsibility of governing the Netherworld's politics, law, military, and public order. - The Three Greats: Refers to the three most powerful Great Demons among the 13 Crowns (Sullivan, Belial, and Levi). These three are the primary candidates for the next Demon King. - The 13 Crowns are usually rational, but they periodically undergo an 'Evil Cycle' where stress or mana accumulation awakens their instinctive destructive urges and desires. - Because the entire Netherworld could fall into chaos if a member of the 13 Crowns enters their Evil Cycle, they make a thorough effort to maintain their reason at all times.
