What Dere Are you? - Based on a survey

Standard ‘Harsh outside, soft inside’ type, acts rudely but is really a huge softie after you break through their shell. (ie. Asuka Soryu, Kagami Hiiragi etc)
name is derived from ‘tsuntsun’, meaning ‘ponted’, and ‘deredere’ meaning ‘sweet’

Initially sweet and affectionate, with their love eventually turning into a stalkeresqe obsession and occasionally a murderous fixation on ‘getting rid of competition’ over time. (ie. Shion Sonozaki, Yuno)
Name is derived from ‘yanderu’, to be ill, and ‘deredere’, meaning ‘sweet’
Not to be confused with Yangire, which is killing for reasons other then romantic attraction

Characters who are entirely sweet and energetic and show this personality to everybody (ie. every character from every moe show ever)

An anime/manga slang term for a character that is cold, blunt, cynical, and pretty much doesn't care if her beloved dies. That's what she is on the outside but she is actually caring and nice on the inside.
Differs from tsundere since tsundere is when the character frequently runs hot and cold between tsun and dere. Kuudere is when the character only occasionally shows her caring side.
Occasionally this is a trait of the true Emotionless Girl, added deliberately by writers or projected by fans.
Compared to yandere and tsundere, the kuudere has a higher chance of being either gender.

Dandere is an abbreviation of だんまりデレデレ[danmari deredere]. だんまり[danmari] means to be calm or to shut one’s mouth up all the time. And デレデレ means, you know, such a sweet attitude. She doesn’t speak at all mostly, but when there’s no one else but you two, she would be sweet to you. In other words, she would be in deredere-mode.

クーデレ[coo-dere].
If she is usually so cold to you and sometimes becomes so nice(sweet?) such as Suzumiya Haruhi, she would be labelled as ツンデレ. But what if she is so cool rather than cold? And what if such an emotionless girl fawns upon you when she bursts into tears? Yes, she would be a type of クーデレ. クー[coo] derives from cool, and デレ[dere] stems from デレデレ[dere dere] which has a nuance of being so sweet. Speaking of クーデレ girls, I can think of Rei Ayanami[Evangelion], Yuina Himoo[Toki meki memorial], or Mai Kawasumi[Kanon]. If you look at any bishoujo anime carefully, you might find this type of girl.

Here’s one more, ウンデレ[un-dere]. Though I can’t think of any example, ウン[un] is a casual form of “yes.” I think “yeah” or ”yep” would be the closet. To get to the point, this type of girl usually agrees with whatever you say by saying ウン！ウン！Perhaps, she might say like そーだよね～[so- dayone～, "yeah right!"] in order to get much intimacy as much as she could. In other words, she might like you from the beginning. If that’s the case, I could think of Hikari Hinomoto[Toki meki memorial 2] who is a protagonist’s childhood mate.

This type of a tsundere is dangerous and scary.
Think of a heroine that started as a villain trying to kill the protagonist but then switched to his side after falling in love with him. One that still makes jokes about killing him once in a while...
