Well like said thats what the other poster said some pages back and he detailed it better too. For volume 1, 2 the numbers seem right with 20-25k week 1 and 50k prints in 1 month. Not sure if he just simplified it for volume 3, but i dont see it in oricon so eh whatever.
3 released a week before Christmas, which always buffs the sales, so i wouldnt be sure its just due to Kono Manga ga Sugoi!. If it boosted it thats good, but the editor picks are kinda just funny tbh.
Couldnt help but chuckle when i saw the male reader category. Might be just me though, but rank 3 with Kowloon Generic Romance especially was just laughably wrong. No sight of the actual best selling newcomer either.
