Overview
洗脳 (Sennou) is a maimai original song that serves as Chapter 3, Episode 1 of the Kotonoha Project (言ノ葉Project), a narrative-driven multimedia series of original songs. The track was composed and arranged by Neru, a prolific VOCALOID producer and songwriter known for dark, introspective works, and features dual vocalists yurin and kakichoco trading lines in a tense, mid-tempo arrangement at 125 BPM. The lyrics grapple with themes of identity, societal pressure, and existential drift, painting a bleak picture of a person caught in the machinery of expectation. The accompanying music video was created by animator Hideaki Tsutsumi.
Added to maimai PiNK PLUS on July 28, 2016, 洗脳 was notable at the time as the first song since maimai ORANGE PLUS to receive a Re:MASTER chart on the same day as its standard difficulty charts. The standard charts were designed by rioN (Expert) and Jack (Master and Re:Master), with the latter pushing into 12+ territory at a 12.9 constant. Years later, the song received a UTAGE (宴) chart in maimai DX PRiSM, designed as a duet chart with asymmetric left/right note layouts, a rare treatment that nods to the song's dual-vocalist structure. The track also crossed over to CHUNITHM PLUS on the same day and later reappeared in CHUNITHM SUPER STAR.
