^LOL even if they sell less than 10K copies (which I doubt they'll do less than 20k) for the last two days they will get 800K. Also, Beginner is already in 11th place for best 1st week sales since ORICON started recording. It'll probably end up in 9th place overtaking Hikki's Wait&See and behind CAN YOU CELEBRATE?. So in answer to your previous question, it's been 10 years since such 1st week sales were possible.
Btw, still loling over the fact it took them
3 days to overtake the sales it took the former #1 yearly almost a year to get and at the rate Hebirote is still charting, any week now it'll be the #2.
