Übel Blatt (Japanese: ユーベルブラット, Hepburn: Yūberu Buratto, ‘Evil Blade’ in German) is a Japanese manga series written and illustrated by Etorouji Shiono. It was serialized in the semi-monthly seinen manga magazine Young Gangan from December 2004 to 2009, when it was transferred to Monthly Big Gangan where it continued until its end in March 2019. Its 170 chapters were collected in 24 tankōbon volumes by Square Enix. The story of Übel Blatt takes place in a medieval, fantasy-like landscape. It follows the steps of Koinzell, who appears to be nothing more than a mere half-human child most distinguishable for the scar over his left eye. He is on a quest of revenge against those who betrayed and killed him and now call themselves the seven heroes of the land.
A side-story titled Übel Blatt Gaiden was published in Young Gangan Big in August 2011. Yen Press began releasing Übel Blatt in North America in October 2014. The series has also been translated into French, where it has ranked amongst the country’s best-selling manga.
A sequel manga titled Übel Blatt II: Shiseru Ō no Kishidan began serialization in Monthly Big Gangan in February 2024.
An anime television series adaptation produced by Satelight and Staple Entertainment is set to premiere in January 2025.
