魔術学院を首席で卒業したウィリアムには高給と安定のエリート街道が開かれていた。だが、彼は自由と可能性に満ちた冒険者の道を選ぶ！ 盗賊、神官、侍の少女３人とパーティを組むことになった彼は、駆け出し冒険者の水準を遥かに凌駕する高い魔法能力と、頭脳的かつ実践的な戦い方で、軽々とギルドのクエストをこなしていく。さらに魔術師を超える導師の称号すら持っていて…!? 実力派の冒険者少女もタジタジ、凄腕魔術師の冒険譚、ここに開幕！
Having graduated from the prestigious Witchcraft Institute at the top of his class, no job is out of reach for William Glenford. Fame, fortune, prestige are at his feet, but William dreams of only one thing: adventures.
Finding companions in a run-of-the-mill guild with an up-and-coming party of girls including a cleric, a martial artist and a beastman catgirl, and being ranked the lowest at the entry level, they immediately begin noticing that he’s grossly overqualified for his role and rank… and that this mage may not be a mere “mage”, but a full-fledged, national-level wizard.
Will William adjust to his party, or will the girls ever hope to catch up to him?
Will the girls accept him regardless of his overwhelming superiority, or will he always be the big fish in the small pond?
