Folgen

Folgen (フォルゲン) is the former Knight Leader of the Kingdom of Falmuth.

Personality
Folgen was seen as a dependable leader, and a trusted retainer that King Edmaris could depend on.

However, he also seemed to care little for fellow Otherworlders, seeing them as mere "materials" to strengthen himself using his Unique Skill Spearhead.

Background
A champion with a long military history. He was summoned by Razen long ago, but had no curse restricting his soul; and, instead choose to become Razen's underling willingly, as a friend.

Story
During Falmuth' war against Tempest, Folgen led a vanguard unit against the nation of monsters. The initial attack was successful, and before he left he told the people of Tempest to surrender or die. He later welcomed Razen to his camp after he managed to retreat from Geld and Hakurou with Shogo through teleportation. Upon learning of Kyoya and Kirara's death, he sarcastically lamented their passing. This angered Shogo, which prompted Folgen to explain that Shogo and his two comrades were only ever meant to be used as "materials" for his Unique Skill Spearhead. He then helped restrain Shogo so Razen could take over his body, to replace Razen's elderly body.

When Rimuru began massacring Falmuth' army to claim enough souls to complete his transformation into a True Demon Lord, Folgen and Razen went to King Edmaris' tent to ensure his safety. Upon confirming that the king was well, Folgen entered the battlefield to stop Rimuru. However, he ended up being easily killed with a single shot to the head by Rimuru's Megiddo, causing his brain to leak out.

Abilities
The knight leader was known as one of the strongest in the Kingdom of Falmuth. Veldora and Ifrit noted that Folgen appeared to be comparable to Ifrit in power, meaning he had to be at the Special A Rank.
