==Background==
"*Hello, Planet." is a song featuring Hatsune Miku by sasakure.UK. It is the fourth song in the Doomsday Series.
*Hello, Planet. tells the story of an android (portrayed by Miku) who wakes up alone in a shelter. She discovers that the world is in an apocalyptic state. She sets herself to take care of the pot containing the last surviving plant. She waits for it to sprout, and to receive a message from the exterior of the shelter. With neither situation taking place and her master missing, she takes the plant and embarks in a journey to find him.
Throughout her journey, she greets every object and place that she meets in a clueless, innocent, and cheerful way. After beginning to deteriorate and break from the journey, she arrives to where her master is, yet she discovers that he has passed. Stricken with sadness, she begins to cry, and her tears make the plant sprout. She dies, but the plant's vines rise through the sky, time, and space, to finally arrive in heaven, where she meets with her master again.
The PV ends with showing the planet's vegetation as beginning to restore, while it displays the phrase "The Last, LOVE SONG from our planet..." Meanwhile, in the shelter from before, a mysterious letter finally arrives. After the letter's delivery, the "deceased" android is depicted resting next to her master's grave along with the plant growing from the pot.
The PV simulates a video game and is similar to "Nijiiro*Adventure", another sasakure.UK song. The art was made mostly in Microsoft Paint.Twitter - @sasakure__UK:＊ハロー、プラネット。のドット絵制作はほぼMSペイントでした👾 A melody from the classic composer Johann Sebastian Bach is present throughout the song.
In the Project DIVA Extend PV, the scene of Miku being led by her master was created from a motion capture where sasakure.UK himself played the role of Miku's master.Twitter - @kiyo3555:ハロプラのミクさんが手を引かれるシーン。モーションキャプチャの際に手を引いていたのはsasakure.UKさん本人。ミクさんが手を引かれていたのはマスターそのもの #マジカルミライ2019 #pjd_segaTwitter - @sasakure__UK:初代projectDIVA収録のハロープラネットMV制作秘話！そうなんです☺️✨懐かしい〜🌱
The tetraphonic ringtone sound of the opening of the 2019 edition is a homage to sasakure.UK's origins as a songwriter.Twitter - @sasakure__UK:ちなみに、＊ハロー、プラネット。(2019: rewake)の冒頭ジングルの音色は、僕が作曲をはじめるキッカケになった、携帯電話の４和音着メロの音色に似せて作ってみました！なにごとも初心は大事。ファミコンの音色にはないタイプの柔らかいニュアンスがお気に入りです🎮

==Trivia==
* The final score shown in the PV, "105900", actually is wordplay. The number 1059 can be read as 10-5-9 (テン-五-九 ten-go-ku). 天国 (Tengoku) means 'heaven', which fits with the moment when Miku ascends to Heaven and meets her beloved one.OtakuxGamer - a look back: Hatsune Miku looks good in 8 bits 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.
