Jin, often credited as Jin ft. Shōichi Taguchi from Sentimental Vector for collaborative works, is a Japanese music artist, composer, lyricist, and producer best known for creating the Kagerou Project multimedia franchise. Shōichi Taguchi is the lead vocalist of the Japanese rock band Sentimental Vector. Together, they have performed several key songs tied to the Kagerou Project’s anime adaptation, Mekaku City Actors. The artist’s most recognized work includes the song Kagerou Daze, which is featured in Mekaku City Actors. Another prominent track is daze, the opening theme song for the same anime series. Both songs were composed and written by Jin, with Taguchi on vocals, blending alternative rock and electronic elements. Jin began as a Vocaloid producer on Nico Nico Douga, gaining fame with the Kagerou Project, a song series that expanded into light novels, manga, and the 2014 anime. For the anime, Jin collaborated with Taguchi to create human‑vocal versions of key tracks. Beyond Kagerou Daze and daze, the Jin ft. Shōichi Taguchi from Sentimental Vector credit appears on the single daze (2014) and the compilation album Mekaku City Records, which includes human‑vocal renditions of other Kagerou Project songs such as Ayano’s Theory of Happiness and Kisaragi Attention. Sentimental Vector, as Taguchi’s primary band, often provides the guitar‑driven rock backing for these recordings. Jin’s musical identity is defined by intricate, pop‑infused rock compositions, layered synthesizers, and lyrical themes of memory, summer, and supernatural events. Taguchi’s clear, emotional tenor voice offers a human counterpoint to the original Vocaloid tracks. Within the anime music industry, Jin is significant for successfully transitioning a user‑generated Vocaloid song series into a mainstream multimedia property, and the Jin ft. Shōichi Taguchi from Sentimental Vector collaboration represents the shift from digital synthesis to live performance, appealing to both Vocaloid enthusiasts and anime rock audiences.
