マトリョシカ (Matryoshka)
Sung By: Hatsune Miku and Gumi Music, lyrics and PV by Hachi


 * Nicovideo Broadcast
 * YouTube Broadcast


 * Made in celebration of Miku's birthday--August 30th--this is a rather chaotic and addictive alternative rock composition which reached over a million hits with incredible speed (less than 32 days which is a feat that most other well-known songs would take from a few months to a year to achieve). The lyrics are almost nonsencially vague, most likely to be about Gumi and Miku breaking down from the stress put on them by their master(s), who are technically making them sing and dance so much just for entertainment. The "Matryoshka" is a russian nesting doll, and the title of the song has not much to do with the song's actual context. The intermissions are descriptions in many different languages from the Wikipedia article for matryoshka dolls. The first is taken exclusively from the Japanese one, but the second combines information from other languages.

 * A song about a couple who fled from the war-torn birthplace. The melody is of old classic Japanese style.
 * There is also a version with Luka and Gakupo, Rin and Len, and Leon and Lola.


 * The song tells a story about a traveler (Kaito) who wanders into a forest shrouded by purple mist; as he goes deeper he begins to hear singing. He finds a little girl (Miku) singing all alone. He joins her, asking her to sing more. As the two sing together underneath a tree, the purple mist begins to become denser. The little girl leads the traveler to a beautiful paradise, where she asks him to stay with her forever. The traveler disappears, and the song ends with the little girl sitting underneath the tree holding the traveler’s scarf. His whereabouts are a mystery.

 * Reverse Rainbow is a song about human feelings that make one feel fun, happy, lonely, withful, and sad, fall in love, or selfish. Rin and Miku, sing about the feelings that are not expressed directly, which seem to be represented by a reverse (or upside down) rainbow. The title of the song sums up the mood perfectly - though the reverse rainbow may look different, or even seem wrong, in its own way it is still very beautiful.

かこめかこめ / Kakome Kakome (Circle You, Circle You)
Originally sung by: Megurine Luka & Hatsune Miku Music and lyrics by: Kamiyanagi Zawazawa-P

The song tells a story of many forgotten children living inside an abandoned orphanage. They proclaim that they are "so very happy" that the viewer has come, and insist that they play a "Kakome, Kakome"[1], which is based on a Japanese game of "Kagome, Kagome ", with them. The author mentioned on his blog that he purposely changed "kagome, kagome" to "kakome kakome" for the song. As the song progresses, it is revealed that the children were guinea pigs for a science experiment to create an elixir for eternal life. In order to test this vaccine, the loser of the games has a limb cut off, and if they survive, then they could not die. As time goes on, the scientists were gone of unknown causes, but the children are left to play forever. The video ends with Miku slicing the viewer in half after evidently losing the game.

雛逃げ/ Hina-Nige (Escape the Princess)
Originally sung By Hatsune Miku and Gumi

Music, lyrics and PV by Hannya-G(はんにゃG) A "sadistic lesbian" spin-off of a classic Hina-Matsuri song ("The Joyful Doll-Festival"), the storyline features characters from the festival's doll display--the Empress (Miku--yet the original English title refers to her as "the Princess") and one of her ladies-in-waiting/handmaid (Gumi). According to the producer (Hannya-G's) introduction, here Miku is a princess (unhappily married to the Emperor) who, grieving that her beloved sister-in-law (the Emperor's elder sister) has married and gone, began to force her affections violently upon her handmaid, Gumi; The latter, terrified and traumatized, attempts to flee the palace and the princess--to no avail. This song is widely acknowledged to be challenging for fandubbers due to it utilizing ultra-soprano vocals and ultra-speed melodies--creating its intense atmosphere.

Green Green ~Midorimushi~ (Green Green ~Euglena~)
Originally sung by Sonika and Gumi

Music and lyrics by Nem
 * NicoNico broadcast
 * YouTube broadcast with English subtitles


 * A relaxing lounge-style song with Gumi and Sonika as the personification of two euglenas (a type of microorganism which has both flora and fauna properties) which follows their story from the time they became friends in a Mexican rice paddy, and covers a few basic facts about euglena's form, function and reproduction. As the story unfolds, it appears that these two euglenas are "held captivity" in a laboratory and they wish to be freed. Moreover, this has long been quoted as one of the most successful of songs featuring Sonika.
