[Machine Translation] Mina the Brave, Yuluere the Knight, Lily the Wizard, and Shano the Monk. They are a quartet of girls who aim to become great adventurers who will one day leave their mark on history by tramping through the unknown lands and overcoming the mighty monsters that come their way.... But they still haven't graduated from the beginner's house...! The four "newbies" have always had unexpected problems and have never been able to complete their graduation quests. But they didn't know it yet... They kept failing at the beginner level quests, but as a result, they accumulated a tremendous amount of experience, and before they knew it, they had reached level 99. This is a story of four novice girls, who are actually the strongest at level 99, weaving their way through their daily lives in a relaxed manner in the name of adventure.
