Ichfeis

A slave knight serving under Glenn, his swordsmanship is almost on the same level as Koinzell. He's been studying under Ms. Gleaa for 5 years and was told if he killed the Hero Slayer, he'd regain his title as Imperial Royalty. He wants to defeat Koinzell and the 'Black Wing' technique in a fair fight, so as to strengthen his own skill.
