and that's with the new oricon rules, impressive600 copies higher than their sister's debut. interesting
did i not say tsubaki would somehow surpass kobushi lmao
Doesn't help that they have been pre-debut for almost 2 years now. Having time to actually build a solid fanbase and more dedicated fans.
I won't say they have surpassed Kobushi yet. Lets see how their next few singles sell. Remember debut hype ALWAYS drives up sales.
Looking at the (relevant) numbers of singles sold, I absolutely would say that they surpassed Kobushi Factory in regards to major debut (and all singles of Kobushi afterwards). Nevertheless I don't think that the comparison to other groups is that important.
The hype/popularity seems to be very high at the moment.
