Black Clover is one of the most exciting anime out there, and it is on the verge of a new arc. The show has been wading into the wide world of training arcs, but that story is about to come to life in a bigger way. After all, Black Clover promised fans an anime-original training arc, and an update confirms that story will begin next week.
The information comes from Black Clover's official English account. The page informed fans the new arc will begin "next week" after a fan asked about the once-teased storyline.
At this point, fans have little to go where this arc is concerned. They know it will be original for the anime, so it has no manga counterpart. Creator Yuki Tabata helped the crew figure out the story, so Black Clover fans are willing to count this arc as canon.
