Endro!

Humans and monsters cohabit on the continent of Naral Island, which has swords and magic. There resides the dreadful Demon King. The Demon King was vanquished by the first-generation hero in antiquity. The Demon King has been revived numerous times over the years since then, as has the hero who opposes him. Girls enroll in an adventurers' school so they can vanquish the Demon King when he reappears. Despite being a little forgetful, Yusha is physically fit for a hero. Seyla, the holy elf, is often in problems because she takes herself too seriously. Fai is a happy fighter who enjoys food. Mei is a shy magician otaku. The four girls enjoy carefree dream lives and make no attempt to slay the Demon King no matter how much time passes as they want to be in the hero party.
