IMAWANOKIWA (今際の際) is a VOCALOID song by Japanese composer, illustrator, and animator いよわ (Iyowa), featuring Hatsune Miku as the vocalist. The title draws from the phrase 今際の際 (imawa no kiwa), meaning "the brink of death" or "the final moment", a framing that casts the lyrics, which describe an encounter with a radiant angel and a yearning for salvation, in a poignant, bittersweet light. Originally released on Iyowa's self-titled album in 2019, the track arrived in maimai as part of the でらっくす BUDDiES launch lineup on September 14, 2023, and is available across all regions including Japan, international, North America, and China. The song's brisk 178 BPM and bright melodic surface contrast with its melancholic lyrical core, a signature tension in Iyowa's work, who handled not only the composition, arrangement, and lyrics but also the music video animation. In maimai, the Master chart, designed by アマリリス (amaryllis), reaches level 13+ with 885 total notes, weaving dense Tap and Hold patterns around the driving rhythm. The Expert chart, designed by 鳩ホルダー (Hato holder) at a 10.6 difficulty constant, offers a demanding intermediate challenge with 41 Break notes woven into its 542-note total. As of its inclusion, IMAWANOKIWA has no appearances in other music games, making maimai the exclusive rhythm-game destination for this track.
