I was disappointed that Rory Mercury wasn’t at the anime convention today. Sailor Mercury was there, though, as was One Punch [Wo]man.
There are a bunch more pictures that will take some time to go through.
Update: I’ve edited as many as I’m going to. As usual, the organizers did their damnedest to make taking pictures difficult, and none that I took are any better than snapshots. You can see them all here.
Rory is obviously going to be a cosplay star, but it’s also a very elaborate costume to create even if you don’t include the halberd. Takes someone dedicated to take on that challenge, I would guess.
