Aiken Azaki, brother to Farrah Azaki, is a member of the Zaran Royal Court. Each royal family is given a title. The Azaki's are called the Fire Family. Therefore, Aiken's official title is Lord Aiken Azaki of the Fire. He is a Zaran Demon Hunter assigned to hunt and capture (or kill if necessary) any and all demons he encounters. He has just recently set his sights on the main character, Dain Rusanigas.
He is a merciless foe, armed up to the teeth with all manners of knives, staves and swords. He is well-versed in all manners of combat. But the attribute that makes him so incredibly deadly is his diligence and perserverence.
