Mifune Ryuuko (Denpa Onna) - she's cute, funny and has nice boobs
Touwa Erio (Denpa Onna) - she's cute (yeah, I like cute girls) and shy, and she's so hnnng with twin tails
Akemi Homura (Madoka Magica) - she's cold but she's hiding her true feelings. She's badass, has a lot of guns and her Unlimited Bazooka Works - awesome.
Momo (To LOVE-Ru) - she's cute, she can fight, she's a little evil and she has a plan. Great plan. Muahahahaha
Akiyama Mio (K-ON!) - shy, cute, moe and sexy girl. What more could you want?
Nagato Yuki (Suzumiya Haruhi no Yuuutsu) - hmmm, silent alien girl with fast, short and accurate answers. But I like her Disappearance version more.
Sakagami Tomoyo (Clannad) - she's pretty, good cook, kind, good at sports and has good kicks (look at chain combo).
Izumi Konata (Lucky Star) - The only one character voiced by Aya Hirano that I like. She's lazy, sarcastic and funny. Just like me, hehe.
Asahina Mikuru (Suzumiya Haruhi no Yuuutsu) - Moooooe. Shy, she often blushes and she has loli body with big boobs like Haruhi says.
Hirasawa Yui (K-ON!) - She's lazy, funny, plays guitar and like sweets. I like sweets too
Tomoe Hotaru/Sailor Saturn (Sailor Moon) - my favourite sailor. She has good looking weapon and she is capable of destroying planets.
Kyouraku Shunsui (Bleach) - I like two hands swordsmanship.
Revy (Black Lagoon) - she's two hand, she likes guns and she's totally badass.
Kyon (Suzumiya Haruhi no Yuuutsu) - I like him for his sarcasm. Great character.
Almost all characters voiced by Kugumiya Rie ;P
And probably more but I can't remember now.
