Kyary's new single sold 14k first week and her new album in June just sold 250k and it has a massive tie-in. Lead single of a new era.
Kana's new single sold 22k first week after 2 best albums that sold a combined total of over 550k+ with a big drama tie-in. Lead single of a new era.
Kuu's new single sold 21k first week with a weak tie-in. No Music Station performance like Kyary and Kana, no huge tie-in. 4th single of an era.
The winner is quite clear
