Chikin TLer here, need some help identifying Yuriko
This panel is supposed to be a Chrono-Lexica reference (the book title means clock dictionary, "Toraware no Tea Time" is on the cup), and there are stuff in the bag that represent the idols as well (Subaru with the baseball, Roco with the ribbon, Anna with the rabbit, Makabe with the card), but I'm not sure what Yuriko is supposed to be?
