J.C. Staff and Kugimiya Rei

So I'm watching Toradora! and on the second episode Taiga went "Urusai urusai!" and I went "Is that Kugimiya Rei?" and sure enough it is. Sometime later I was curious about which studio is doing this and it turned out to be J.C. Staff and then I went "wait, didn't they also do...?" and they actually did Zero no Tsukaima, Shakugan no Shana, and Hayate no Gotoku. Seems like J.C. Staff is just picking up adaptations that they can cast Kugimiya Rei as the wrathful loli in. Which is win. WIN I tell you. Now back to Toradora!...
