Colorado Bulldog

Colorado Bulldog was used as the first ending theme (ED 1) for Kamisama no Memochou (Heaven's Memo Pad), the 2011 anime adaptation of the light novel series. The song is performed by Mr. Big and was written by the band's credited songwriters, bringing an existing hard rock track into the series' ending sequence rather than an original anime commission. As a pre-existing release, it gives the episode closer a distinct identity rooted in the band's polished late-era catalog and in the wider sound of 1990s hard rock.

Musically, the track is built on punchy drums, a busy bass line, distorted guitar riffs, and a brisk, swaggering groove that gives the closing animation a sharper edge. Its compact, high-energy arrangement and memorable hooks soften the transition from the episode’s mystery plot while still preserving tension, and the song’s confident momentum suits the series’ urban detective atmosphere. The result is an ending theme that feels lively, slightly defiant, and still tightly aligned with the show’s unresolved mood.
