4/26/09: The text at the top is the announcer, I didn't want to block the outfits. This was supposed to be a 2-page thing, but I didn't have the time for the 2nd page. I wonder if you were expecting fanservice.
If you don't get Lethe's "costume": http://en.wikipedia.org/wiki/Pac_man
Fairly recently, whenever I drew the back of Lethe's head this is what came to mind, so why not use it? It might be hard to make out, she just grabbed a marker and wore glasses backwards. What kind of thing did you think she'd wear?
