Overview
The song ハオ (Hao) is a Vocaloid track produced by DECO*27, one of the most prolific and commercially successful producers in the Japanese Vocaloid scene, known for hits such as Ghost Rule, Hibana, and Sand Planet, featuring Hatsune Miku on vocals, with arrangement by Hayato Yamamoto and a music video by the creative team OTOIRO. Released as a digital single in 2024, the song made its rhythm-game debut simultaneously in maimai DX PRiSM PLUS and CHUNITHM VERSE on April 24th, 2025.
The track's most recognizable feature is its repeated chant of 好好好 (hǎo hǎo hǎo), the Chinese phrase for "good good good," which serves as both the song's hook and the source of its katakana title ハオ. The lyrics, written by DECO*27, paint a self-deprecating portrait of romantic insecurity: the narrator obsesses over the "supply and demand" of love, cycles between wanting to hate and needing to be loved, and ultimately lands on a defiant "this is fine" refrain. Lines like 逆におっけー (it's okay in reverse) capture the song's playful, contradictory mood, and were repurposed as the name of an in-game title awarded for 1 Miss. In maimai, the MASTER chart (level 13, constant 13.2) was designed by 鳩ホルダー (Hato Holder) and stands out for its unusually high Slide-note count of 136, among the densest slide layouts for a level-13 chart in the PRiSM PLUS era. The EXPERT chart, designed by Luxizhel, originally launched at level 10 but was adjusted down to level 9+ with the CiRCLE PLUS update.
