Post an anime character in the 'dere' type...^^

i'm pretty sure Kaede is a yandere

I think Shōko Kirishima from Baka and Test would qualify as a yandere.

Suigintou from Rozen Maiden is a dandere.

Homura Akemi from Madoka Magica.

Taiga from Toradora!!!

Deres from TMoHS---

Tsundere~ Kyon- actuación high and mighty, pretending not to like stuff, but actually a loving person.

Kamidere~ Haruhi Suzumiya- It's in the name. actuación as if she o he is god, but with a -dere side hidden away.

Dandere~ Yuki Nagato- Might appear very silent and even emotionless at first, until someone "pulls their trigger" and it comes out that they were just shy.

Deredere~ Mikuru Asahina/ Itsuki Koizumi- Sweet and loving all the way.

Yandere~ Ryoko Asakura- May appear all loving and kind at first, but can get very aggressive, obsessive and violent when it comes to her o his affections.

These are just my guesses, but I think it suits pretty much ^^

Kirino a tsundere

Mikoto Misaka! a certified tsundere X3

Dere..well Ryuuguu Rena from Higurashi is definitely a Yandere..

I thing Soi Fong.. She is cold and bitchy most of the time but deep deep inside she has a heart!

Fate,from Mahou shoujo lyrical nanoha is a Kuudere type!
cool,bit unemotional,but sweets later on!
