Since there is no English dub, the only way to watch the series is with the original Japanese audio and English subtitles. Here’s where you can find it:
As of 2026, the English dub of Beelzebub is legally available on (following their acquisition of FUNimation’s catalog) and Amazon Prime Video (via third-party channels). Some regions also have it on Hulu . Be warned: The series was never fully dubbed beyond episode 60—it covers the entire anime run, as the Japanese series didn't adapt the final manga arc. So you get a complete 60-episode experience plus OVAs, all in English. beelzebub anime dub episode 1
