Lei "Demon King of the North" Magnus
About
Lei Magnus was a famous and powerful human sorcerer during the time of the Kouma War. Lei was the inventor of two of the most powerful spells, the Dragon Slave (originally called the Dragon Slayer) and the Blast Bomb. One of the first public displays of the former spell's power was when he killed a 1,600-year-old arc dragon with it. He is also the one who created the Demon's Blood Talismans, one of the Slayers world's most potent artifacts for magic capacity amplification.
A fragment of Ruby Eye Shabranigdu resided within the sorcerer, and for the mazoku, one of the objectives of the Kouma War was to awaken that piece. Lei was consumed by hatred towards other humans when he witnessed the bloody massacre of the war fought between human nations in the early years of the Kouma War, and the seal on the fragment of Ruby Eye was broken. Little did he know that the war was staged precisely in order to have this effect by Hellmaster Fibrizo. During the war, Lei Magnus-Shabranigdu gave the Demon's Blood Talismans to Xelloss as a gift in exchange for doing a great favor for him. Whatever this favor was has never been stated officially, but it was hinted to be connected to the mazoku priest's achievements during the conflict.
However, Fibrizo's plan was cut short when Aqualord Ragradia defeated Lei Magnus-Shabranigdu and sealed Chaos Dragon Garv into a human body, at the cost of her life. The fragment (as well as Lei) was frozen in ice and sealed in the Earth. He soon gained the title of "Demon King of the North". Lei and the fragment of Shabranigdu are still alive, but are unable to leave the spot where they are frozen.
The Lord of Nightmares appears as L in all the afterwords, discussing events and trivia with Author (Hajime Kanzaka) and occasionally Subordinate-S (Demon King of the North). She often beats up on them, usually with a shovel, but other times with other objects. When in the afterwords Subordinate-S was asked about his gender, he stated that he is male, another part of him is also male, and that he doesn't know anything about the other five parts, becuase he's still playing dead. Hajime Kanzaka draws new year porstcards every year with L and occasionaly Subordinate-S in human form, and sometimes transformed in various animals by L.
