Kuudere

Kuudere

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.

C.C. - The kuudere of Code Geass

Kuudere / Dandere - A Kuudere and Dandere are very similar, (a Kuudere is a "cool" silent type whereas a Dandere is simply a silent type, however, there isn't much of a difference between the two so you can refer a character as either a Kuudere or Dandere since they basically mean the same thing.) A good example of a Kuudere is a Minami from Lucky Star, (she is generally quiet, however, she does talk quite a bit,) whereas a good example of a Dandere is Nagato from The Melancholy of Haruri Suzumiya because she will only talk when spoken to.

Kanade Tachibana (立華奏, Tachibana Kanade) is one of the students of the Afterlife school and the said school's Student Council President. She is also referred to as Angel by the Afterlife War Front, a nickname coined by Hideki Hinata and later used by the group's leader Yuri Nakamura to refer to her after discovering her unusual abilities.

As the school's Student Council President, Kanade is tasked with the responsibility of ensuring that the students are able to cope with their personal problems. This eventually clashes with Yuri's determination to blame God for her hardships in life, and she becomes the target of the Afterlife War Front when it was founded.

Kanade has long silver hair (often mistake in the Visual Novel to be a shade of blue) that reaches about waist length. She wears the standard uniform of the Afterlife School, a white petticoat under the skirt, white knee-high socks and brown loafers and a pale blue barrette clip on the back of her head, keeping a part of hair up. She is one of the shortest characters in the series, being only 150 cm (4'11 feet) tall. 

Kanade does not appear to be less than a typical human being in physical form, but this is contrasted by her lack of detectable emotion, even in skirmishes with the SSS which usually end up with her being injured, It is difficult to understand what she is thinking due to her rarely showing any outward emotion. In later events, she is shown to have abandoned being friendly because of the rules of the world she is in, as her newly-found friends inevitably leave her when they disappear.As the series progresses, she shows a little of her emotions, mostly to Otonashi.
