Razen

Razen (ラーゼン) is the Chief Sorcerer of Farmus Kingdom, and one of the summoners of many otherworlder in Farmus.

Personality
Razen is a prideful individual who believes he's one of the best sorcerers there is. But he's also wise and knowledgeable enough that he knows that there are many opponents that even he could not beat.

Like many in Farmus, Razen is shown to be extremely selfish and cruel, happily summoning and enslaving people from other worlds, only to later sacrifice them to increase his own power, made worse by the fact he destroys their souls rather than simply killing them.

Background
Razen is a brilliant sorcerer who has served many years as a Court Mage in Farmus, part of why he has lived so long is his Possession Spell. He was once a student under the Great Sorcerer Gadra.

Demon Lord Awakening Arc
Razen attacked the Jura Tempest Federation together with his nation but realized too late how powerful his enemies were. He possessed Shogo Taguchi's body after saving him from Geld and thought that with his abilities he could put a fight against a Demon Lord. However, after surviving Rimuru's Megiddo attack thanks to his new Unique Skill Survivor and seeing the devastation of Falmuth's army he realized he could never defeat Rimuru so he tried to escape with King Farmus but was instead captured alive by Diablo.

The Octagram Soars Brightly Arc
