Overview
ヒアソビ (Hiasobi) is an electroswing VOCALOID original by Camellia (かめりあ, Masaya Oya), featuring Hatsune Miku (初音ミク). The track debuted as the title song of Camellia's 2022 album ヒアソビ, accompanied by a music video animated by りゅうら (Ryura). Lyrically, the song explores forbidden desire and reckless romance, a metaphorical "playing with fire" that the title evokes.
The song followed an unconventional path to maimai. It was originally submitted for the ninth Project Sekai NEXT competition but was not selected at the time. Roughly one year and nine months later, in January 2024, it was added to Project Sekai as a "loser's revival" track, a song that earned a second chance through community or editorial support. From there it crossed into SEGA's broader rhythm-game ecosystem: CHUNITHM LUMINOUS in May 2024, オンゲキ bright MEMORY in September 2024, and finally maimai でらっくす CiRCLE in October 2025. In maimai, its MASTER chart (level 13+, constant 13.7, designed by Jack) and EXPERT chart (level 10, designed by Luxizhel) serve players across the upper-intermediate and expert range.
