Welp, the YAB situation just got worse. AGAIN. Shirayuki Tomoe from NijiJP just announced an indefinite hiatus, as most of her songs were produced by, with, or in YAB's studio. In a membership stream, she basically confirmed that Nijisanji has no in-house studio, so most, if not all of the songs produced in their first years were done with 2, maybe 3 studios that the company (i.e. Tazumi) had as reference that they could rent.
The lack of intrastructure in Nijisanji is already sorta egregious, but this puts a larger problem in evidence: YAB was company reference. Which raises a few red flags... If Nijisanji had no evaluation of the studio, how the fuck did they make it reference? If they really didn't know about the drugging, how can they not have accompanying staff to official business outside corporate grounds? How many more talents will have their channels essentially wiped off music for this fuck-up? And how the fuck doesn't Niji has a fucking studio after ALMOST EIGHT YEARS?!
