Sylphide

About
Sylphide is a former adventurer that formed a party with Bird Lithfie and the others to defeat the Four Witches of Kathtom. Apparently, he used to be Shizuka Masou's subordinate, being nicknamed the Wind Warrior.

He tried to enter Shizuka's Mansion in her Maze but, in order to do so, he needed to get the Key the succubus Ralga was guarding. He challenged the succubus but he was fucked dry by her and had all his energy and vitality drained completely. His skin turned pale, dry and thin. Ending completely exhausted with no energy and life force, he tried to remain on a safe location in the dungeon where he met Rance, warning him about the Succubus Ralga. He later ended up perishing despite his attempts of survival.

He was 33 years old at the time of his death and was a relatively decent adventurer, with a Spear Combat skill and a Level Cap of 16 which he reached. While he looked mediocre and weak when compared to someone like Rance, the fact that he managed to reach the mansion means that he's competent enough as an adventurer to at least avoid fighting the high-level monsters of the maze.

Trivia

 * He's one of the few humans to reach his Level Cap, though it's a fairly low one.
 * He's also one of the few people that have a Spear Combat skill level that aren't from JAPAN and the first on to appear in the series.
