Overview
初音天地開闢神話 (Hatsune Tenchi Kaibyaku Shinwa, "Hatsune's Genesis Myth") is a Vocaloid song by cosMo＠暴走P (cosMo@Bousou-P) featuring Hatsune Miku. It was composed as the official theme song for 初音ミク マジカルミライ 2021 (Hatsune Miku Magical Mirai 2021), an annual concert and exhibition celebrating Vocaloid culture organized by Crypton Future Media. The song later arrived in maimai DX UNiVERSE PLUS on March 24, 2022, as part of the niconico & VOCALOID genre, and also appeared in SEGA's other rhythm titles CHUNITHM NEW PLUS and オンゲキ bright around the same period.
The track tells a cosmic narrative through its lyrics: a "chosen singer" (Miku) is reincarnated into a fantasy world, where her voice creates life, calms earthly conflicts, and brings hope across time and space. The title itself, 天地開闢 (tenchi kaibyaku), a classical Chinese-derived phrase for the genesis of heaven and earth, positions Miku as a primordial force shaping a newborn world through song. The lyrics culminate in the promise "次は君のいる世界に この歌を 届けに行くよ" ("Next, I'll deliver this song to the world where you are"), a line that also appears as an unlockable in-game title.
Musically, cosMo@Bousou-P delivers his signature high-energy production: 240 BPM, rapid synth arpeggios, and Miku's characteristic vocal tuning driving a relentless, uplifting arrangement. The maimai version is a shortened edit (2:33) relative to the full album release on the 初音ミク「マジカルミライ 2021」OFFICIAL ALBUM (2:42). The jacket illustration was created by 乃希 (Noki), with video production by 藍瀬 まなみ (Aise Manami).
