Black clover is the magical wizard version of one peice & its funny because it's so formulated to resemble one piece.
Black Clover originally wanted to be a much darker, but Shonen Jump stepped in and said no.
Since AOT started Shinen Jump has kicked themselves in the teeth multiple times regretting not letting AOT in the magazine. The author wasn't going to change his story & it paid off.
Now we have Shinen Jump trying to break into being more edgy with specficly Jujitsu Kaizen, but only after giving a little more freedom to Demon Slayer.
Shonen Jump is introducing at least one dark toned series at a time in order to finally bring in something they beleive will out shine AOT in the next 4 years.
