"ラプラスショコラ (Laplace chocolat)" is a VOCALOID track by composer Kai, featuring Hatsune Miku on vocals. The title deliberately fuses two contrasting ideas, Laplace, evoking Laplace's demon and the philosophical question of deterministic fate, with chocolat (French for chocolate), a symbol of sweet indulgence and romantic uncertainty. The lyrics play out this tension through a narrator caught between self-deprecating humor and earnest longing, repeatedly calling out to "Laplace" for answers about a future that remains stubbornly dark. The song was originally released as a self-titled album in 2024, with a music video produced by Kai alongside illustrator 羊谷あく. ラプラスショコラ made its rhythm-game debut in maimai でらっくす CiRCLE on February 13, 2026, the eve of Valentine's Day, a fitting seasonal alignment for a chocolate-themed song. In the Asian version of the arcade release, it followed one week later on February 20. The song offers four DX chart difficulties. The Expert chart (level 9+, constant 9.6) was designed by Luxizhel, while the Master chart (level 12+, constant 12.9) was crafted by はっぴー, a notes designer known for Slide-heavy configurations; the Master chart packs 135 Slide notes into its 691-note total. Clearing the song rewards the title "教えてくれラプラス" (Tell Me, Laplace), and a FULL COMBO unlocks "小悪魔メイクで求愛中" (Courting with Little Devil Makeup), both phrases lifted straight from the song's lyrics.
