In this world, everyone can use magic... and in a land called the Clover Kingdom, two young men, Asta and Yuno, strive to become the Wizard King, the greatest of all magic users. Asta and Yuno were abandoned together at a church in Hage, a village in the boonies, and lived as brothers from that day onward. For some reason, however, Asta never developed the ability to use magic, even when Yuno had already mastered wind magic. Now, at last, the boys are turning fifteen, the age at which children receive their own grimoires. Asta has high hopes that receiving his grimoire will awaken his latent ability to use magic, but when the time comes...
Once a year, all around the Clover Kingdom, 
all of the 15-year-olds are gathered,
مرّة كلّ سنة، يجتمع جميع من يبلغون من  العمر 
،خمسة عشر سنة من جميع أنحاء مملكة كلوفر
kommen wie jedes Jahr einmal
alle Knaben und Jungfern von 15 Lenzen
Una vez al año, los jóvenes del
Reino del Trébol que cumplen 15 años
Una vez al año, los jóvenes del Reino
del Trébol que cumplen 15 años
Una volta l'anno,
tutti i quindicenni del Regno di Clover
Uma vez por ano, em todo o Reino Clover,
todos que têm 15 anos são reunidos
Раз в год, во всём царстве Клевер
собирают тех, кому исполнилось пятнадцать.
