In a world where magic is everything, Asta and Yuno are both found abandoned at a church on the same day. While Yuno is gifted with exceptional magical powers, Asta is the only one in this world without any. At the age of fifteen, both receive grimoires, magic books that amplify their holder’s magic. Asta’s is a rare Grimoire of Anti-Magic that negates and repels his opponent’s spells. Being opposite but good rivals, Yuno and Asta are ready for the hardest of challenges to achieve their common dream: to be the Wizard King. Giving up is never an option!
