Overview

チエルカ／エソテリカ (Cerca/Esoterica) is a maimai original song born from a collaboration between Vocaloid producer Tsumiki and vocalist Yuu Miyashita, released for maimai でらっくす Splash PLUS on May 28, 2021. The track debuted as part of the Sky Street Area 2 Perfect Challenge event, requiring players to accumulate 540 km of travel distance in the area before they could attempt it, a unlock structure that gave the song an event-like status during the Splash PLUS era before it became available by default in UNiVERSE PLUS. Musically, the composition is driven by a brisk 205 BPM pulse and an unusual time-signature structure, shifting from 7/4 into a 10/4→11/4→10/4→9/4 sequence in the latter half, lending an irregular, forward-surging feel that complements the dark narrative imagery of its associated flavor text. Tsumiki, a Vocaloid P known for his original songs with katakana titles, composed, arranged, and wrote the lyrics. Miyashita, active across YouTube and Pixiv as a singer, composer, and illustrator, handled vocals in his first maimai appearance. The music video, jacket art, and related materials, directed by illustrator Ryusei, are notable for featuring the first official depiction of the character Noah's face. The song's MASTER chart, designed by Safata.Hz at a difficulty constant of 14.3, is recognized for its dense patterning and a well-known Break note accent on the chorus's opening word "ねえ" (nee), while the EXPERT chart was designed by はっぴー.
