Übel Blatt

Übel Blatt is a dark fantasy action TV anime adaptation of the manga by Etorouji Shiono, centering on the protagonist Koinzell in a brutal world of survival and tragedy. Produced by Satelight, with direction by Takashi Naotani and series composition by Tatsuya Takahashi, this 18+ series delivers a grim and intense fantasy experience crafted for fans who seek mature, edge-of-your-seat storytelling rooted in darkness and conflict.

Across a vast and troubled land, whispers of a fearsome black sword have begun to spread — they say that whenever its dark blade is unsheathed, none who face it walk away alive. This is the world of Übel Blatt, where mystery and danger lurk behind every rumor. At the center of it all is Koinzell, a young boy of unknown origins whose mastery of the black sword far exceeds what his appearance might suggest. Yet whether he truly stands behind the bloodshed spoken of in hushed tones remains an open question. Adding to the tension, a group of formidable warriors known as the Traitorous Lances — once believed to have fallen at the hands of the legendary Seven Heroes — now set their sights on this enigmatic swordsman. Caught between relentless pursuers and a world full of unanswered questions, Koinzell's journey unfolds as a sweeping epic fantasy filled with fierce battles and deep secrets waiting to be uncovered.
