Secret

Background
The song's has never had its meaning released by Ryuuuu although many popular conclusion have been drawn based on the lyrics.

The Plagiarism of aRth
Originally, the video was uploaded by aRth. However, about 1 year after its upload Ryuuuu, the creator of the song caught up with the video. Ryuuuu had linked to the song file via a url, but had not uploaded the song onto Nico Nico Douga. From the url, aRTH obtained access to the song and then uploaded it onto Nico Nico Douga into aRth's own account. It wasn't until much later that Ryuuuu noticed aRth's upload and the plagarism was announced, by then the video had many views. As of consquences of the plagarism, aRth's account and all videos on it were deleted from Nico Nico Douga. As proof Ryuuuu uploaded the instrumentals of the song. It has also been found that aRth has also uploaded other songs that aren't his on his account.


 * aRth's Nicovideo Plagiarized Video
 * aRth's Youtube Plagiarized Video

The PV remains on Nico Nico Douga as Ryuuuu did not object to its pressence because of its popularity and only requested the correct creator of the song changed to Ryuuuu's name and aRTH's removed.

Trivia

 * The name "secret" is often believed by fans to imply a hidden message or meaning is held within the song. However, the title is believed to have been given its name by aRth from the fact originally the song was hidden from view by Ryuuuu and the file which contained the song was labelled "secret". "Secret" was merely meant to imply the song was not meant to be made for viewing as Ryuuuu never originally gave the name "secret" as the title of this song.
 * The pink-haired girl in the PV is not Luka.
