All songs

Overview

分解収束テイル (Bunkai Shuusoku Teiru, "Decomposition Convergence Tale") is a narrative-driven original song created for the maimai rhythm game series, serving as Episode 5 of the Kotonoha Project 2nd Season main story. The track brings together three key figures from the Japanese vocaloid and doujin music scene: vocalist un:c (あんく), singer konoco, and composer cosMo＠暴走P (cosMo@Bousou-P), who handled composition, arrangement, and lyrics. The song's music video was produced by Tsutsumi Hideaki (ツツミヒデアキ) with illustrations by Shikimi (しきみ). The song is deeply tied to the BLACK ROSE area narrative within maimai DX FESTiVAL, set on the fictional Teos Island, birthplace of the alchemist MacRitch family. The story follows characters confronting the truth about the Black Rose disease and a celestial conspiracy involving angels and gods. Lyrically, the song weaves imagery of hidden churches, manipulated memories, and a defiant "heavenly hallelujah," culminating in questions about fate, free will, and sacrifice. Both a human-vocal version (featuring un:c and konoco) and a Vocaloid version of the track exist, reflecting cosMo＠暴走P's signature approach of producing alternate vocal renditions.
