Hajimaru no wa, Sayonara

, performed by ON/OFF, is the second opening theme for the anime Beelzebub. Hajimaru no wa, Sayonara is ON/OFF's sixth single. It was used from episode 11 through episode 23.

The original span was to start from Episode 13 (now Episode 11), but following the 2011 Tōhoku earthquake and tsunami, two episodes have skipped airing, while all other releases, including the release of the next two episodes and this opening, remained on schedule. Hence, Episode 11 is the first episode to feature this opening theme.
