Background
This song is about a girl who is extremely shy and constantly says "eto...", which is the Japanese equivalent of saying "um...". Stuttering eto creates the word Toeto. Throughout the song, the girl slowly overcomes her fear.

The song was accompanied with a PV, which featured Megurine Luka in a small, child-like form, wearing a cat hat. The character was obviously named Toeto. The song, and character produced from it has enjoyed many Nico choruses, including a mega-chorus that included more than 50 people singing at one time. It also included all of their Toeto avatars. The song is even on iTunes here (open only if you have iTunes) as well as a rendition by Rin.
