Now that I’ve finished listing each chapter of the manga and detailing which anime episodes use material from each chapter, I thought I’d make this bonus guide of all the anime episodes that didn’t use any material from the manga. I’ll also make a note of episodes that are predominantly filler but used a sliver of manga content.

King’s Memories
- Episode 213
- This episode contains very brief elements from Chapters 323 and 324, but is otherwise almost entirely anime-only material
- In general, Episodes 212-219 were heavy in anime-only material, but all but 213 had enough manga material to not point out specifically
Ceremonial Battle
- Episode 222
- The episodes surrounding this one make changes where this episode can’t be outright skipped, but almost nothing in this episode appears to correspond to a chapter from the manga
Oh my- that’s a lot of filler episodes! Since I’ve only started reading the manga, I had no clue that the eps from 212 to 219 were so loosely adapted.
