In the distant past, a terrible Demon King arose on Nararu, and a brave Hero also arose to defeat the Demon King.
A new key visual and the story introduction have been revealed for Endro~!, an upcoming original slice-of-life / fantasy TV anime about a group of young would-be heroes going to school to learn how to defeat the Demon King.
Together, these four form a party and embark on a laidback fantasy life while waiting for the Demon King to appear.
