This is a rough sketch of what Black Clover could be, not what it becomes. The animation stutters and the character designs look sloppy next to the manga, but the voice acting sells the setup anyway, Yuno's actor especially carries scenes that could have landed flat. It works as a gateway for people who need to know if this series is worth their time, and for manga readers it's a curiosity piece that shows how early Studio Pierrot was still figuring out the show's visual identity.
Asta dreams of becoming the greatest mage in the kingdom, even though he cannot use any magic at all. His fortunes change when he receives an extremely rare five-leaf clover grimoire, which grants him the power of anti-magic. Whether a boy without magic can truly rise to Wizard King remains to be seen, but Asta refuses to give up. This one-episode Black Clover special mixes action, comedy and fantasy. It was screened at the Jump Special Anime Festa 2016 events and later came bundled with the limited edition of the 11th manga volume.
