Mikuru invites Kyon on a shopping trip. While it's not a date, Kyon likes to pretend it is. Mikuru takes a dress into the changeroom, while Kyon is surprised by Nagato, who also appears to be dressed up (apparently a store employee made her do it). Nagato vanishes while Mikuru appears in a low-cut outfit.
Koizumi interrupts the "not-a-date", and while Mikuru runs off, he tells Kyon that everyone "wears masks" and that Mikuru's nature is likely one as well. Kyon brushes it off, but feels upset that the "date-like atmosphere" was ruined.
Mikuru calls Kyon and tells him to meet at the usual café. Kyon meets her there, and she admits she wasn't just having fun, but was also doing work for her superiors. She starts to admit the truth about herself when Haruhi calls, telling everyone to meet at the same café. Kyon has to hide and reappear after Haruhi gets there so she won't interpret their meeting as a date. The other members of the SOS Brigade quickly arrive, Yuki still wearing her new outfit. Haruhi then insists they go on a shopping trip.
