Series title
  • "終末シリーズ"
  • Romaji: Shūmatsu Series
  • English: Doomsday Series
Published June 4, 2010


The Doomsday Series is a collection of chiptune or video game-like songs composed by sasakure.UK that talks about the gradual destruction of Earth and humanity due to a war.

The series contains four songs covering the events of the war starting with escalating world conflicts, the war itself, the imminent cataclysm, and finally ending with the post-apocalyptic period. Each event is sung by a different VOCALOID representing different individuals, each one with their own circumstances, convictions, goals, and message.

The songs were released in inverse order, with the two final components released first and then the two previous afterwards. A fifth song, "*Sayonara, World End.", was released as an exclusive bonus in the album Do Vocaloids Dream of Doomsday Birds?, which contains the entire series as well.

Being the chronologically first song and the last one to be published, this song shows the events previous to the war. In this song, Rin represents a typical schoolgirl with no major interests other than the person that she likes, and although she is aware of the political situation of the countries and all the rumors and prediction about the end of the world, she isn't concerned about them as she can be with her loved one.

As the conflict escalates, one day her love interest leaves her to go to a "far away" place, leaving Rin with her feelings unconfessed and with her heart shattered (although the situation isn't explained, it can be inferred that he joined the war or left the country due to the imminent chaos). Being too young, Rin declares that she doesn't understand the world, the war, or the catastrophe, and that she is only aware of the feeling of loss.

Rin despairs that her heavy feelings are uncontrollable and that a single letter is not enough to express herself. She fills numerous letters and, not knowing who to send them to, decides to scatter them across the world to bring some hope or find someone that could give some happiness to the devastated and sad world.

The PV ends with scenes that reference the previously published songs of this series in their chronological order before finally showing a silhouette of a person resembling Rin's loved one opening one of Rin's messages, which begins "For you and your beloved".

ぼくらの16bit戦争 (Bokura no 16bit Sensou)

"Bokura no 16bit Sensou" (Our 16-bit Wars) is an ambiguous song that expresses the feelings and ideas of someone involved in the war. The song opens with the singer wondering why things became the way they are and questioning the ideas of "justice" and "sacrifice", lamenting that "order" has failed them. The singer describes how there was only a hole at first, perhaps referring to a small conflict or problem. But due to the spread of propaganda, the hole was enlarged. The rest of the song describes the war and the singer's role in it.

The song's PV contains a sequence with small stick characters that some people interpret as the plot, but due the abstract nature of the PV, this can't be confirmed. The nature of the song itself and the abstract PV allows a wide variety of interpretations.

ワンダーラスト (Wanderlast)

Video ChaKoro
One of Luka's first big hits and the first published song of the series, it expresses the feelings and thoughts of someone near his/her end. Like the previous song, there isn't a clearly defined plot and it is open to interpretation. The singer is never specified, although the PV shows the illustration of a wrecked female-shaped robot with salmon-colored hair and the chest open exposing her heart, surrounded by butterflies and flowers.

The singer starts by saying how they were told that people just want a place to sleep. By the time the singer knew of "the end", things had already fallen at an uncomfortable rate. The singer says how if there was a God, he/she wouldn't ask him for a thousand rainbows in the large sky. Instead, the singer only wishes for a song to be delivered to their loved one.

The singer than expresses that they wouldn't mind disappearing if only they could make their loved one smile or continue holding their hands. The song finishes with the singer repeating the chorus "LET'S SING AN ENDLESS SONG, BEFORE I REACH THE END..."; as the singer repeats the chorus, the PV begins to show jamming and the voice becomes more and more distorted, then ends as if a transmission was cut off.

Lyrics sasakure.UK
Video ChaKoro
Being the second song to be released and the last one of the chronology, this song relates how an android (Miku) wakes up alone in a shelter, only to discover that the world is devastated. She is set at the care of a pot that contains a seed, the last thing that her master showed her. She waits for the plant to sprout and to receive a message from the exterior. With neither situation taking place and knowing that her master is missing, she takes the plant pot and embarks on a journey to find them.

Through her journey, Miku greets every object and place that she meets in a clueless, innocent and cheerful way. Broken and deteriorated from the harsh travel, she finally arrives to where her master is, only to discover that he is deceased. Stricken with sadness, Miku begins to cry, and her tears make the plant sprout. As a lifeless Miku collapses, the plant's vine rises and takes her through the sky, through time and space, and finally arrives at heaven, where she meets with her master again.

The PV ends showing the planet's vegetation restored while the phrase "The Last, LOVE SONG from our planet..." is displayed. The scene switches to Miku's shelter where a mysterious letter arrives through the mailbox before the screen blurs and distorts before finally ending with the "deceased" Miku resting next to her master's grave and the plant growing from the pot.

Lyrics sasakure.UK
An exclusive bonus track from the Vocaloid wa Shuumatsu Tori no Yume o Miru ka? album, this song is a sad "answer song" to "*Hello Planet." In this song, Miku recalls her old memories and tries to continue her journey. She says good-bye to everything that she loved and to her memories. Finally, wishing to meet with her beloved one again she says goodbye to the little sprout in the flowerpot, to her own tears and to this world.

The song ends with the same phrase from "*Hello, Planet.", 「あいたかったの"キミ"に オハヨーハヨー」 (Aikatatta no kimi ni ohayō-hayō) hinting that she finally meets with her beloved one in the next life.


The series is a collection of 5 songs total, all of which are compiled in the album titled Do Vocaloids Dream of Doomsday Birds?, along with other works by sasakure.UK as well as remixes from other producers.

Video gamesEdit

This song was featured in the following video games:

This song received its own mini-game in the expansion pack for Project DIVA: "DLC 1: Miku Uta, Okawari". This is a platform video game with 4 levels, and an 8-bit style similar to the one shown in the original PV. It also features two different endings.


  • The title of the series album is a direct reference to the science fiction novel "Do Androids Dream of Electric Sheep?" by American writer Philip K. Dick.
  • About Our 16-bit Wars:
    • At one point, the lyrics mention the number 65535. This number is the highest number that can be represented by an unsigned 16 bit binary number, referencing the song title, Our 16-bit Wars.
  • About *Hello Planet:
    • The Original PV style simulates a video game and is similar to "Rainbow-colored*Adventure" (another sasakure.UK's song).
    • The final score shown in the PV, "105900", actually is wordplay. The number 1059 can be read as 10-5-9 (English ten-go-kyuu/ku; ten-go-ku). 天国 (Tengoku) means 'heaven', which fits with the moment when Miku ascends to Heaven and meets her beloved one.[1] There are also multiple other references, such as 003390 for Sasakure, while 022160, nijiiro, has been speculated to be related to Nijiiro*Adventure, another sasakure.UK song with a similar style of PV.
    • The song received its own minigame in the expansion for Project Diva: "DLC 1: Miku Uta, Okawari". This one is a platform video game with 4 levels with a 8-bits style similar to the one shown in the original PV. It also featured two different endings.
