Frequently Asked Questions
When should I watch Zatch Bell! 101st Devil?
It's a standalone story best watched after finishing Season 1 (episode 50), since it assumes familiarity with the core cast and the demon battle premise.
Is 101st Devil connected to the main story?
No — it's a self-contained film with a demon exclusive to the movie (Zophis), and its events aren't referenced again in the TV series.
