Dandadan began as a manga by Yukinobu Tatsu, serialized on Shonen Jump+ from 2021, before Science SARU adapted it into an anime in 2024. The series follows Momo Ayase and Ken Takakura, nicknamed Okarun, as ghost and alien encounters spiral out of control. Its opening moments and start cues were clipped by fans for edits and soundboards as the anime spread online. Like the To be Continued cue from JoJo, it became shorthand for launching into something absurd, and it remains popular because the show mixes horror, comedy and romance at full speed.
