This might just be the very first character development and focused arc we get for Shiori 😦 Really hyped to see if she really is the late-game threat since we know literally nothing about her so far.
Also I alr noticed other comments pointing out how Shiori’s so damn adorable with the kids but the panels where she’s describing the “hidden side” of the others kinda just shows how much she cares for the others and how much she pays attention to them by even recognizing their mannerisms. This could just be because everyone in SSS has been stuck with each other for so long 😂, but still.
