TOP 2 SINGLES:
x->1->1->1->1 - Kanjani8 - (108,637 + 44,896 + 14,683 + 7,714) (x1.75) = 307,878
x->2->2->2->2 - Kobukuro - (26,416 + 19,250 + 8,705 + 5,724) (x1.75) = 105,166
As I've replied in one comment earlier, Eito hasn't had the luck of using the 1.80 factor, considering the previous singles (except Wahaha) never reach the sales expected by using 1.80. But just in case this time around it happens, here's another calculation:
x->1->1->1->1 - Kanjani8 - (108,637 + 44,896 + 14,683 + 7,714) (x1.80) = 316,674
x->2->2->2->2 - Kobukuro - (26,416 + 19,250 + 8,705 + 5,724) (x1.80) = 108,171

Either way, Musekinin Hero has already surpassed the 300k mark, which will make this single the highest-selling Eito single in debut week since KanfuFighting! XDDDDDDD
Next mission is to surpass KF's total sales and I'm pretty positive that Musekinin Hero can do it. GANBARE EITO! :)
