Although they're not wearing their costumes, I tagged it with the event tag Seek Solve Summer Walk! since it has the entire group from the event present plus it makes reference to the event theme of camping.

They're also doing the same pose (and wearing the same jumpsuits) as the Secret Society Blanket in the movie key visual, so I'll add the respective cosplay tags.
