Koinzell

Köinzell (real name: Ascheriit) is known as "The Hero of the Frontier" for defeating the leaders of the Black Wing Army and later as the "Hero Killer" due to his relentless pursuit of vengeance against the Seven Heroes. He is the main protagonist of Ubel Blatt. Originally, he was one of the 14 Heroes and a member of the Lance of Betrayal, a group that was framed and attacked by the Seven Heroes. Köinzell was the sole survivor of this betrayal and returned 20 years later to exact revenge on his former allies.
