Endro! - S01

On Naral Island, a land of adventurers and magic, the age-old struggle between the Demon Lord and the Hero repeats endlessly. The current Hero, Juulia "Yusha" Charldetto, is nearing the end of her quest with her trusted party: the dependable priest Seiran "Seira" Élénoir, the mysterious mage Meiza "Mei" Endust, and the lively warrior Fai Fai. In their final clash with the Demon Lord, Yusha's group attempts a dangerous spell to banish their foe through time-but the magic backfires, hurling them back to an era before the Demon Lord's rise, before Yusha became the Hero, and even before they finished their adventurer training. Stripped of their future memories, the four girls set out once more to become the Hero's Party and vanquish the Demon Lord. Unbeknownst to them, the Demon Lord was also thrown back in time-retaining her memories but trapped in the body of a child. Taking the name Mao, she secretly joins the adventurers' school as a teacher, plotting to thwart Yusha before she can fulfill her destiny. Now, as Yusha and her friends pursue their goal, the very enemy they hunt walks among them, hidden in plain sight.
