Jun'ichi Suwabe

Asta and Yuno are two orphans who want the same thing: to become the Wizard King. Locked in a friendly rivalry, they work hard towards their goal. While Yuno excels at magic, Asta has a problem uncommon in this world: he has no powers! But, on the day they receive their grimoires, they surprise everyone. To reach their goal, they’ll each find their own path to greatness—with or without magic.

Japanese animated film based on the Gōka Kyakusen story arc (volumes 11-14) of Yana Toboso's hugely successful Black Butler manga series.
