Idol Rabier

Idol Rabier (イドル＝レイビア) is a Melromarc nobleman and Raphtalia's previous abusive owner.

Appearance
Rabier is a nobleman of a revolting appearance. He is an overweight, middle-aged man with an unkempt mop of frilled, strawberry-blonde hair and a minimal mustache in the same color shaped like two small "leaves" over his upper lip. He dressed in elegant clothing of black, golden, and purple hues, with some white frills to match his royalty status, a dark purple cape, olive-yellow pants, black riding boots, and most of the time flaunted a cynical smile on his plump face.

Personality
He is an amply-proud fanatic of the Church of the Three Heroes and has a twisted logic in his belief. He hates and looks down on demi-humans, taking sadistic pleasure in their suffering, even children. His torture knows no boundaries, as he is willing to torture any allies or believers of the Shield Hero, including his own kind. He was an abusive master of slaves and had no qualms on readily killing his own soldiers for an advantage. He is also a great coward, as shown when he begged for mercy (mostly from Raphtalia) when he had never granted any to anyone.

He doesn't care for anything or anyone but himself. In his maniacal thirst for killing the Shield Hero, he comes to the point of releasing in the middle of the town an ancient monster sealed ages prior in an obelisk, which seemingly led to his own death and the carnage of the town people.

Natural and Learned Abilities
Idol is an experienced soldier from the demi-human wars that he had fought alongside King Aultcray Melromarc XXXII. He was skilled with military affairs, swords, and whips, the two latter ones which he was also shown to use to torture and kill Demi-Humans and all those who dared to oppose him. He brandishes a whip that curses anyone it strikes. Naofumi believes that he has experienced the class-up ceremony due to his raw strength. He was able to kill one of his guards in a single strike.

Magic
Idol was also shown to have a considerable level of magical power, as he was able to free an ancient monster sealed via strong magic confinement.

Background
Idol fought in many wars and aided King Aultcray, especially against Siltvelt, which probably explains the reason for his hatred for Demi-Humans. He is a fanatic, through and through. Belonging to one of the fanatic factions of The Church of the Three Heroes, Idol believes that torturing and killing demi-humans is a "service" to his God, and also believing that killing the "Devil of the Shield" will assure him a place in Heaven.

After the First Wave, Idol purchased the survivors of Lurolona Village and tortured the demi-human children in an underground dungeon beneath his mansion. While the law of the land does not explicitly forbid mistreating slaves, the torture which Idol frequently enjoyed was illegal. He took pleasure in their suffering, which led many to mental breakdowns and even death. Raphtalia's former best friend, Rifana, was one of the many victims to succumb to torture. After seeing her friend's corpse, Raphtalia became psychologically detached which led to Idol losing interest and eventually selling her back to the slave trader. This inadvertently saved her from imminent death.

Trivia

 * His name was revealed in his anime debut and not in any other material.
 * His surname, Rabier, is a possible pun on "rapier," a European sword with a long, pointy blade made specifically for perforating rather than slashing, given the kind of sword usually seen with him. The same surname could also allude to "rabies" or "rabid," which fits perfectly with his aggressive and hateful personality.
