Got back from Anime Expo. I felt that Iori key chain was pretty unique compared to the other ones because she came with her signature usagi. Turns out I bought the very last one lol.
And I thought the Iori cosplay spot-on. This was the only IM@S cosplay I saw around until right around where I was tired and in a hurry to leave where I saw more cosplayers at the entrance.
Overall, I couldn't find Makoto. Orz
You're lucky you saw any iM@S cosplay at all. When I went to Anime North, a convention where Haruka's VA came from Japan to visit, I only saw a few Producers and someone wearing a Harukasan drawing on his head.
I almost bought that Ami figurine, but I got the secret Shiny Festa nendoroids instead and pulled Iori, who's my favourite. I was pretty happy.
