Thing being that most Fairy Tail fillers (Starry Sky and Eclipse Celestial Spirits Arc) have been canonized through the manga openly referencing them You can of course still skip them, but just saying, they're canon now Also, I personally don't like much JC Staff for Fairy Tail, they already did Edens Zero and stripped Mashima original artstyle bare bone, and with Season 2 only 2 scenes had good animations So I'm a little distrusfull, but let's hope for the better
