Speaking as a JJK stan: Every anime release has been so insanely peak that I can easily forgive the manga ending being shit. It’s just good art, and they’ve polished the turd well thus far.

Why not? There’s literally nothing stopping them from changing the ending aside from budget constraints. Tons of anime completely change the ending.

There have been many instances where the Anime changed and branched from the Source material. Sometimes for the better, many times for the worse.

So saying the anime “can’t fix the ending” isn’t really correct. The studio and production committee could definitely do that.

The questions here are more about:

• will they change it?
• If they change it, will that ending be better or worse?
