Hakusensha’s editorial department and the writer’s official Twitter account have reported that Kentaro Miura, the writer and artist of the manga Berserk, has passed away at the age of 54 of an acute aortic dissection.

Berserk, which started in 1988 and was still ongoing as of Miura’s death has been adapted into several anime series, one in 1997 adapting the Golden Age Arc (which was followed by a trilogy of films adapting that arc), and a later series in the late 2010s picking up where the Golden Age Arc left off (which has run for 3 seasons).

Miura’s work had been credited as influencing various works, from video games like Dragon’s Dogma, Dark Souls, and Monster Hunter and the design of Cloud Strife’s Buster Swordin Final Fantasy VII, to various other anime and manga series like Demon Slayer and Vagabond, as well as the Netflix Castlevania animated series.
