apparently all of floor 2 had cameos like that before they were officially introduced (besides tsuneyo who you dont see but hear). so close noriko, if you had just turned around you wouldnt have had to deal with maya storming out and everythingView attachment 2689040
I dunno if this is original or added with the rework but just after the first halloween chain event there's Rin's performance review and look who's in the background. Not sure how long there is to go till the christmas party where the second school gets eaten by the sinkhole but i imagine it's at least a bit, i don't recall any chain events pumping right up against each other until chapter 3-ish.
