GiraGira Romantic

"GiraGira Romantic" (ギラギラRomantic) is the sixteenth single released by Japanese hip-hop group Lead, released over a year after their previous single on 5 August 2009 (Sunnyday was released at the end of July 2008). The single charted in the top twenty of the Oricon charts, taking the No. 12 spot for the week and remaining on the charts for four weeks.

The single was released in four CD+DVD combo packs, with each version corresponding to a member of the group. Each edition contained a bonus song, which was performed as a solo by whichever member's edition was purchased. The b-side "High Tension Day", however, was performed by all members and available on all versions.

"GiraGira Romantic" also became the official starting point for the group's annual releases. For the next four years, the group would only release one single, which would be released during the summer months. It also became their final single under the Pony Canyon sub-label Flight Master, whereas they would move to the main label.
