If you are diving into the world of Black Clover , you know one thing for certain: Asta never gives up. But sometimes, even the most dedicated Magic Knight might want to give up when faced with a wall of "filler" episodes.
Watch the anime-canon arc (130-157) once. On a re-watch, stick strictly to the manga canon.
With 170 episodes under its belt, Black Clover is surprisingly light on filler compared to other long-running Shonen giants like Naruto or One Piece . However, the filler it does have is placed in some tricky spots.
Because the manga was still releasing chapters, Black Clover created a long stretch of anime-original content set the massive Elf Reincarnation arc. This is technically filler, but it focuses on the Heart Kingdom training and a conflict with a devil worshipper named Megicula .
