Each sister is voiced by her respective actress from the anime: Ichika (Kana Hanazawa), Nino (Ayana Taketatsu), Miku (Miku Ito), Yotsuba (Ayane Sakura), and Itsuki (Inori Minase). The song originally appeared on the TV Anime "Gotoubun no Hanayome" 5th Anniversary Best Album, released in 2024, before joining the maimai song library.

The Master chart, designed by Luxizhel at level 12+ (12.8), features a high Break-note count of 67, a distinctive signature that rewards precise timing throughout the full 2:21 arrangement.
