2 - Rin, Yuuka, Louise
3 - Aiko, Athena, Aono
4 - Kiyoura, Kiri, Tenshi (yes I know it's officially spelt "Tianzi")
5 - Haruna, Mikoto, Chihiro (dammit, the anime failed so hard on such an awesome character)
6 - Ami, Shana, Yui (ok, this one's an anime blog vote - I dropped ToLoveRu long before she appeared)
Digging through my image archives (my image hunting habits oscillate in intensity and are mostly focussed on Touhou), I find a Kiri image which might be too powerful for this early on - but hey, everyone reposts good images from earlier rounds so it doesn't hurt to toss out good ones early. I'm the guy who wrote "Age naide~" with his image.
