Surprised that no one has questioned if the scarves are Ami's and Maya's and why they are there again for sale.
I mean, Ayane also managed to get a green scarf for herself afterwards for matching purpose (despite not being the exact same type as any of the two shown); the item itself may not carry as much weight, at least less than how they appeared the first time in Stray Cat.
(BTW I always thought the two mannequins with the green scarfs on were not mannequins but two angels standing still LOL)
Since the only person that has any emotional tie with the green scarf is Maya (not even Sensei before Stray Cat I think), so for now it’s hard to properly gauge how impactful or meaningful that event would be if it's just Chika in the scene, but I am for sure curious.
Unless the green accessory is somehow the key to get to the roof and fix everything; that would be anticlimactic for me
