Only the promised hero can defeat the Demon King of Naral Island, with both entities being resurrected each time. This time, a group of four girls makes up the hero’s party, though they might not seem like the most typical heroes… Yuusha is the hero herself, a bit absentminded and unconventional. Their cleric Seira is the serious, motherly type, while Fai is the rough warrior who loves to eat. The party is rounded out by Mei, the mage who lives for collecting magic cards.

Ann is a princess and one of the best students at Mysteria Academy, where students learn the magical arts. Grea is also a princess, but she prefers to stay in the background because of her half-human, half-dragon form. As these two grow closer together, they will become each other’s best friend, despite their differences.
