Fans report that Crunchyroll’s Episode 4 appears to be an unfinished or early-production version, missing finalized animation frames.
Meanwhile, Amazon Prime Video’s Episode 4 features the fully completed and polished animation from A-1 Pictures.
Viewers noticed visual quality differences, with some scenes on Crunchyroll looking less detailed and less refined.
The issue is believed to be caused by a premature upload, and an updated version may be released later.
