Eri's in the back. ;_;
And Yossi's in the center, for once

In terms of the costume, I think it would have looked much better overall if the red tops were all just tube tops (like Reina's and Eri's) instead of tank tops and all the other variation on there. Yossi's just looks quite bad, in my opinion. It's bordering on looking cheap, unlike the other girl's. It could have done without the huge silver belt too.
Did anyone else think "Spiderman" when they first saw the costumes? Haha. At first glance, it looks like something a skanky Peter Parker would wear to save the day.
I don't know whether to like or hate Risa's hair

Reina's hair is cute, but yeah, I just wish she had more variety with it again instead of pigtails again. Sayumi's hair is the best in my opinion <3 The rest have styles we've seen many times already, blah.
