Ubel Blatt (Übel Blatt) is a manga about Koinzell, who was once known as Ascheriit. Before the events of the manga, he earned the title of Blatt Meister, or “Blade Master,” for his exceptional sword skills. He was chosen by the Emperor of Szaalenden to be one of fourteen elite warriors on a dangerous mission to defeat the evil nation of Wischtech. Armed with lances blessed by the Emperor, they journeyed into enemy territory. Despite losing three warriors along the way, Ascheriit and three others continued and succeeded in their mission. However, upon their return, the seven who had abandoned the quest ambushed and killed them. The traitors then falsely claimed to the Emperor that the four slain warriors had betrayed them. They were hailed as heroes, known as the Seven Heroes, while the four slain warriors were labeled as traitors, named the Lances of Betrayal. Ascheriit, the sole survivor, now seeks revenge against his former comrades, who have risen to power and are hailed as saviors.
