This work, which will be the de facto first release work under the name of composer&producer SAIJI, welcomes IA as vocals, and while being an extension of the sound of the produced vocaloid unit neoromancia, SAIJI himself plays the drums, and the rock band S. 4. The band sound is finished with G bassist RYO. A four-minute story is formed by a driving sound that unfolds dramatically with a classical flow and modulation, an emotional vocal of IA, and a profound ending with a string quartet at the end.
