Dandere - Similar to moe/kawaiiko, but different enough to be interesting.
Yandere - Self explanatory; They're awesome. (http://www.cavestory.org/forums/showthread.php?t=2831 if you want to research things about Yanderes)
Cat Girl - Can it get cuter than this? (Azu-nyan's cat-girl meow is an example)
Small Girl Big Gun - Rawr?
Genki Girl - Do I really need to explain?
Miko - Kawaii!
Tsundere - I actually hate this type of character a bit (with a passion, though) thanks to Zero no Tsukaima. It's still a nice archetype.
Childhood friend - Sometimes makes a great plot development. Sometimes.
Nekomimi - Same reason as Cat Girl, except the general concept of ears - Even Horo from Spice and Wolf may fall into this category. Why? I don't know.
Love Freaks - They're unpredictable and awesome.
