Rozen

Rozen is an officer of the Order of the Seven Lances, the personal unit of Glenn. He and his retinues help Koinzell, until learning of his true nature. Rozen overheard Koinzell's secret, that he is Asceriit and the true lances of betrayal are the seven heroes. However, Rozen does not agree with Koinzell's mission of vengeance because he believes that no matter if the seven heroes truly were betrayers the empire's stability is built around the "Seven Heroes". He is often conflicted because he has heard the true story about the supposed Seven Heroes and Lances of Betrayal. (Source: Übel Blatt Wikia)
