"K2G", also known as Kimi Ni Go! (〜キミにGO!〜), is a song by Puffy AmiYumi featured in the episode "Mad Mod". It was released in the album "NICE.", the same album containing the animated series' theme song. The introductory carrier melody of the song was inspired from the same component of the 1990 song How Was It for You? by English rock band James.
