The Japanese term ''tsundere'' refers to a character who "runs hot and cold", alternating between two distinct moods: [[http://www.youtube.com/watch?v=aS4mRlNCV8g tsuntsun]] (''aloof'' or ''irritable'') and [[http://www.youtube.com/watch?v=CBFXUospjjk deredere]] (''lovestruck'').

The term was originally used to describe characters who began with a harsh outgoing personality, but [[CharacterDevelopment slowly revealed]] a soft and vulnerable interior over time. Over the years the character archetype has become [[{{Flanderization}} flanderized]], and is now [[StockCharacter generically associated]] with a character who flips between the two emotional states at the slightest provocation.

The tsuntsun can range from the "silent treatment" to "lovestruck kindergartener who pushes you into the sandbox." The reasons behind a Tsundere's behavior vary widely, but usually boil down to the conflict between their feelings of affection towards a love interest, and their reaction to having those feelings.

The Tsundere [[StockCharacter stock characterization]] is very popular with writers of RomanticComedy because the conflicts between the two personality facets can be easily utilized to generate both drama and comedy. It also acts as a source of WishFulfillment: specifically, the idea that every independent, hardened and [[{{Jerkass}} just plain jerkish]] love interest (male or female) has a squishy emotional centre that will embrace you after you crack the outer shell.

Tsundere can be divided into two main categories, depending on their default mood:

* '''Type A''' (alias Type ''Tsun'' or "harsh"): These Tsundere have ''tsuntsun'' as their default mood. It takes someone special to trigger their deredere side. The intensity of the tsuntsun can range from "I must glare and fight my way through life" (Louise of ''LightNovel/TheFamiliarOfZero'') to grumpy pessimism (Kagami of ''Manga/LuckyStar''). It's about which part of the tsundere personality is the public face and which the hidden. If the Tsundere is TheRival, she is more likely to be Type A. [[RivalsTeamUp Helping a rival out]] is usually accompanied by a line like "Don't get me wrong, [[IWasJustPassingThrough I'm not doing this for you]]." \\
\\
Type A can overlap with a JerkWithAHeartOfGold, but usually not. The moods of a Tsundere tend to switch in reaction to the actions of select people or adverse scenarios; the deredere side usually only comes out when someone has acted in a way to trigger it. A JerkWithAHeartOfGold is jerkish in general regardless of whether the other person is mean or nice, and shows their HiddenHeartOfGold only when the situation warrants, regardless of how the other person had been acting. Male characters in particular should be considered for JerkWithAHeartOfGold status, as arguably because of {{Double Standard}}s, men are generally that instead of tsundere, although the {{kuudere}} subtype is more equally split in gender. Oranyan is sometimes used to refer to a male tsundere character - incorrectly since it means the complete opposite.

* '''Type B''' (alias Type ''Dere'' or "sweet"): These Tsundere have ''deredere'' as their default mood. They are [[NiceGirl sweet, kind and generous]], but just happen to have a [[PervertRevengeMode hidden violent]] [[UnprovokedPervertPayback side as well]]. In this case, temper is almost always triggered by someone or something else, usually a LoveInterest. Either they have BelligerentSexualTension, are an AccidentalPervert, or just have no idea how to [[WhatIsThisThingYouCallLove handle feelings of love and attraction]]. May also overlap with ViolentlyProtectiveGirlfriend if her LoveInterest is threatened or in danger. \\
\\
Type B should not be confused with a {{Yandere}}. If a Type B Tsundere were really convinced that their LoveInterest didn't want them, they would revert back to the deredere side and probably enter an IWantMyBelovedToBeHappy phase, while {{Yandere}}s are NotGoodWithRejection at all and have been known to get [[MurderTheHypotenuse downright]] ''[[IfICantHaveYou murderous]]'' under such circumstances.

See also the [[Analysis/{{Tsundere}} Analysis page]] for more detailed information on common "strategies" employed by {{Tsundere}} characters, and other, related topics. [[http://www.escapistmagazine.com/news/view/116164-Science-Explains-Tsundere-Appeal this site]] has an explanation on the appeal of the tsundere character.

A common way of showing that a Tsundere has [[CharacterDevelopment mellowed or has had her heart won over]] by the LoveInterest is to have her shift from Type A to Type B. If her motivations are inquired, she will often engage in a SuspiciouslySpecificDenial, complete with a LuminescentBlush and total evasion of eye contact (cue the squeaks of {{Moe}}).

In addition, there appear to be three major subtypes which while more common with Type-A may sometimes fit with Type-B.

'''"Wolf-Girl" Tsundere''' who can't or won't be honest about her feelings, is quick to judge her love interest (or the main character in a harem comedy) badly, and usually pelts him with violence at the slightest provocation, real or imagined. Bonus points if she calls him an idiot for not understanding her feelings outside his earshot. Prime examples are Nana from Manga/ToLoveRu, Asuka Langley Soryu from Anime/NeonGenesisEvangelion (though she also has traces of other types), Fumino from LightNovel/MayoiNekoOverrun, Naru Narusegawa from Manga/LoveHina, Louise from ''ZeroNoTsukaima''.

'''Discipline Tsundere:''' Usually a fellow student assigned some role of authority, hall monitor, school president, etc. who is rather strict in rules enforcement. She is quick to blame the love interest for breaches of etiquette and tries to punish him for it. This usually surprises him in that he's getting singled out for attention over others. Romantic interest seldom comes to mind as the reason (at least until he gets wind of further evidence). Prime examples: Yui of Manga/ToLoveRu, Asuna of OreShura.

'''Tragic Past Tsundere:''' This poor girl has a DarkAndTroubledPast that makes understanding her feelings, let alone expressing them highly problematic for everyone, including herself. As such, approaching her is rather delicate, and if she approaches someone else, expect many misunderstandings good or bad. While violence towards the Love Interest is not required, it often occurs. Prime Examples: Stella Satellizer of [[Manga/{{Freezing}} Freezing]]. Yami of Manga/ToLoveRu. (Rito has not one or two, but THREE Tsundere in his UnwantedHarem), Taiga Aisaka from LightNovel/ToraDora. The aforementioned Asuka Langlay Soryu from Evangelion also turns out to be one, once her past is revealed.

When paired with a JerkWithAHeartOfGold, together they produce BelligerentSexualTension. If done poorly, the result is an UnintentionallyUnsympathetic JerkSue. Compare with WellExcuseMePrincess, JerkAss, and JerkWithAHeartOfGold. Contrast with SourOutsideSadInside, which shares the spiky exterior but has depression and self-doubt rather than kindness hiding underneath. When {{Flanderized}} tends to overlap with MoodSwinger. Also see DontYouDarePityMe and AngerBornOfWorry; both of them likely actions with this character type. AloofAlly may show the same hot-and-cold behavior but for differing reasons. ShanaClone is a specific subtrope with a particular set of characteristics. Because of their low tolerance for stupidity, they are always EnragedByIdiocy.

Please do not confuse this trope with a MoodSwinger, who flips between ''all'' the emotional states (not just tsuntsun and deredere) and is more of an inherent mental problem encompassing more than just their romantic life. Also don't confuse with PlayingHardToGet, where a love interest ''deliberately'' chooses not to reciprocate her pursuer's interest until she's sure he's hooked.

Psychologically, tsundere-like behavior could be an example of "splitting," a maladaptive coping mechanism wherein a person [[BlackAndWhiteInsanity alternately idealizes and undervalues others]], including potential romantic partners.
