Overview
"約束" (Yakusoku, meaning "Promise") is a self-cover song by Japanese VOCALOID producer and singer-songwriter Harumaki gohan (はるまきごはん). The track originally existed as a Hatsune Miku VOCALOID song before Harumaki gohan re-recorded it with his own vocals for a more personal, intimate rendition. The accompanying animated music video was produced by Studio Gohan (スタジオごはん), adding a visual layer to the song's nostalgic, summer-themed story about a childhood promise between two people.
Added to maimai でらっくす Splash PLUS on August 20, 2021, the song sits in the niconico & VOCALOID genre category. Its Master chart, designed by シチミヘルツ (Shichimi hertz), holds a level constant of 12.0, while the Expert chart was designed by はっぴー (Happy). The song's gentle BPM of 136 and lyrical themes of innocence and memory give it a distinctly bittersweet, melancholic atmosphere that contrasts with the more energetic tracks typical of its genre.
