Youm Farmenas

Youm Farmenas (ヨウム・ファルメナス) is a Human known as the Rising Hero-King Farmenas of the Farmenas Kingdom. He used to be known as the wandering Champion Youm. Youm is secretly a vassal of Demon Lord Rimuru Tempest.

Personality
Before meeting Rimuru, Youm gave the impression of a leader among outlaws, but he actually always had a heart of gold. After meeting Rimuru and becoming known as a Champion, this dynamic reverses and he appears to be a heroic figure while on the inside he still preferred to act more casual instead.

Appearance
He has a toned body, darkened by the sun. Neither tall nor short. He looked as if he never let his guard down. By no means ugly' rather, he has a pretty good face.

Background
Youm used to be a prisoner of Count Nidol Migam's Territory of the Kingdom of Falmuth until he received the order from the Count to lead a mission as the leader of the newly formed 30-man strong Frontier Expedition Force to scout the movements of the Orc Lord that has been spotted in the Great Forest of Jura. Rommel was supposed to watch over Youm's group during the mission and report back to the Count, but Youm managed to threaten Rommel into dismantling the contract magic binding Youm and most of his group and by using his charisma even managed to make Rommel join Youm's endeavors wholeheartedly.

Relationship

 * Mjurran: Youm is in love with Mjurran and they end up marrying each other. Mjurran even states that she wouldn't mind being tied down for the short duration of a human lifetime. They later have a daughter named Mieme.
 * Grucius: Youm's rival in love, and later Captain of Youm's Royal Knights.
 * Rimuru Tempest: Youm's boss. Youm became both the Champion Youm, as well as the Hero-King Youm Farmenas on Rimuru's orders. Rimuru saved Mjurran from Clayman's control despite Mjurran's hostile actions against Tempest, so Youm ended up feeling a deep sense of gratitude towards Rimuru on-top of Youm already having pledged his allegiance to him.

Trivia

 * All instances of "Hero King" are actually supposed to be "Champion King," as he is referred to as a Champion (英雄) in every case and never as a Hero (勇者). So technically it should be Champion King (英雄王), but the official translators decided to stick with the term Hero King instead, as can be seen in the case of Gazel Dwargo who bears the same title.
