Granted, I haven't checked the Series Stats in a while, but suddenly I see this manga #1 in Monthly Rankings and quickly going up in the other rankings. I haven't read this series yet, but based on the description and reviews, It doesn't seem so outstanding. Did something happen in the current arc to increase the popularity, or has it just been steadily gaining popularity without me noticing?

me too, I haven't check mangaupdates for so long, and here I am seeing something like Saki on #1 wow, just wow... I mean a lot of my anime friends don't like the anime Saki even though I recommended to them... so I never thought the day I would see Saki become #1 on series stats

Square Enix brand is shining
