Ouran High School Host Club began as Bisco Hatori's manga before the 2006 anime adaptation by Bones made its host club cast widely known. Its ending theme, Shissou by Last Alliance, became closely tied to the show's light, energetic mood. Short outro clips later spread through anime edits, soundboards and fan videos, where this closing cue is reused to signal a playful finish. Years later it still appears in nostalgic shoujo posts because a few seconds are enough for fans to recognise the series.
