—— Julia Shardet, unemployed ♪ People and monsters coexist in the sword and magic of the mainland "Naral Island". A terrible "demon king" used to exist there. Long, long ago, the first brave men defeated the demon king who appeared on Naral Island. Since then, the demon king has been resurrected in all ages, and the brave men who confronted him have appeared again... The girls attend the Adventurer School in order to defeat the demon king who appears at any time. Yuxia, who is a little off-line but has the physique of a brave. Sera, the elf saint who has been working hard because of being too serious. Fai, a cheerful warrior who likes to eat. Mei, a quiet fanatical magician. The four people who aim to form a brave team, no matter how long it takes, start a leisurely fantasy life that never seems to defeat the demon king.
