Based on the opening moments of the teaser, it seems like "Black Clover: Sword of the Wizard King" is reaching out to those who may be unfamiliar with the manga or anime series. The text establishes the central theme of the struggle between Asta and Yuno, but it would still be a good idea to catch up on the show. Thankfully, Crunchyroll has every single season in order available for streaming. The streamer has three different subscription plans available priced at $7.99, $9.99, and $14.99 respectively. Each plan also comes with a 14-day free trial.

There are 170 total episodes of "Black Clover," so this would be an epic binge that is certainly worth it before the film drops on March 31. The first three seasons are the longest, with 51 episodes each in Seasons 1 and 2, 52 episodes in the 3rd season, and 16 in the final season. Although the last episode of Season 4 serves as a tentative series finale, "Black Clover" Season 5 has been rumored. As revealed by Comicbook.com, the reason for this is the continuation of the manga in addition to the series nearly catching up with the last released volume once the writing for Season 4 was completed. Until a future announcement, going through all the episodes before the movie arrives is well worth the time investment.
