Overview
ゆりかご ("Yurikago," meaning "cradle") is the opening theme for the mobile rhythm game 神椿市協奏中。 (KAMITSUBAKI CITY ENSEMBLE.), a title set in the KAMITSUBAKI virtual-artist universe. The track was composed, arranged, and written by MIMI and sung by the CeVIO AI voicebank KAFU (可不), giving it the signature clarity and gentle melancholy that characterizes much of MIMI's vocaloid catalog. At 120 BPM, the song unfolds over a mid-tempo piano-and-synth arrangement, with lyrics that frame music itself as a cradle, a space where wandering emotions take shape and everyday life becomes a melody. The animated music video, created by illustrator and animator 山下RIRI, accompanies the song's reflective tone with dreamlike visuals.
ゆりかご arrived in maimai on March 13, 2025, as part of the でらっくす PRiSM PLUS update, available across Japanese, international, and US regions from launch. Its Master chart, designed by 鳩ホルダー, sits at level 13 (constant 13.0) with a 654-note count that leans heavily on Slide and Touch patterns, while the Expert chart by Luxizhel offers a level-9 stepping stone. A collection challenge ties the song to 月光 (Tsukikage), playing both tracks in a single credit unlocks the title "そのすべてはーー協奏の果てに。" Beyond maimai, ゆりかご later appeared in CHUNITHM VERSE, arriving in June 2025 for Japanese cabinets and October 2025 for Asian regions.
