第 1 集: 在四葉王國的一場關鍵儀式中，Asta 和 Yuno 獲得了他們的魔導書。

In the Clover Kingdom, the orphans Asta (an outgoing, competitive boy) and Yuno (a quiet boy with an affinity for magic) want to become the next Wizard King, the most powerful wizard in the kingdom. One day, Asta and Yuno attend a magic ceremony to each receive a Grimoire suited to their abilities. Although each grimoire has a picture of a standard three-leaf clover on the cover (symbolising integrity, hope and love), Yuno receives an extremely-rare four-leaf-clover grimoire (symbolizing good luck), while Asta is embarrassed when he does not receive a grimoire. Yuno is attacked by a disgraced former magic knight intent on stealing the Four-leaf clover grimoire. Asta is badly beaten by the thief, who ridicules him for having zero magic potential. Asta's determination to win and Yuno's words of friendship summons a damaged black grimoire with a legendary five-leaf clover, which supposedly symbolizes the Devil. (Source: Wikipedia)
