"Oh, Arnold, how I love you. And yet I hate you! And yet I love you. And yet I hate you! And yet I LOVE you."
Helga Pataki, Hey Arnold!

The Japanese term tsundere refers to a character who "runs hot and cold", alternating between two distinct moods: tsuntsun (aloof or irritable) and deredere (lovestruck).

The term was originally used to describe characters who began with a harsh outgoing personality, but slowly revealed a soft and vulnerable interior over time. Over the years the character archetype has become flanderized, and is now generically associated with a character who flips between the two emotional states at the slightest provocation, and usually at a specific person rather than a general sociability problem.

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 stock characterization is very popular with writers of Romantic Comedy 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 Wish Fulfillment: specifically, the idea that every independent, hardened and 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:

See also the Analysis page for more detailed information on common "strategies" employed by Tsundere characters, and other, related topics. this site has an explanation on the appeal of the tsundere character.

A common way of showing that a Tsundere has mellowed or has had her heart won over by the Love Interest is to have her shift from Harsh to Sweet. If her motivations are inquired, she will often engage in a Suspiciously Specific Denial, complete with a Luminescent Blush and total evasion of eye contact (cue the squeaks of Moe).

In addition, there appear to be three major specific "Classes", which while more common with Harsh may sometimes fit with Sweet.

  • The "Wolf-Girl"-class 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 To Love-Ru, Asuka Langley Soryu from Neon Genesis Evangelion (though she also has traces of other types), Fumino from Mayoi Neko Overrun, Naru Narusegawa from Love Hina, Louise from The Familiar of Zero.

  • The Discipline-class 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 would be Yui of To Love-Ru, Asuna of Ore Shura, Kyou of CLANNAD, and Misaki of Maid-Sama!.

  • The Tragic Past-class Tsundere: This poor girl has a Dark and Troubled Past 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 include Satellizer of Freezing, Yami of To Love-Ru (Rito has not one or two, but THREE Tsundere in his Unwanted Harem), and Taiga Aisaka from Tora Dora. The aforementioned Asuka Langley Soryu also turns out to be one upon reveal of her past.

When paired with a Jerk with a Heart of Gold, together they produce Belligerent Sexual Tension. If done poorly, the result is an Unintentionally Unsympathetic Jerk Sue. Compare with Well, Excuse Me, Princess!, Jerk Ass, and Jerk with a Heart of Gold. Contrast with Sour Outside, Sad Inside, which shares the spiky exterior but has depression and self-doubt rather than kindness hiding underneath. When Flanderized tends to overlap with Mood-Swinger. Also see Don't You Dare Pity Me! and Anger Born of Worry; both of them likely actions with this character type. Aloof Ally may show the same hot-and-cold behavior but for differing reasons. Shana Clone is a specific subtrope with a particular set of characteristics. Because of their low tolerance for stupidity, they are always Enraged By Idiocy.

Please do not confuse this trope with a Mood-Swinger, 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 Playing Hard to Get, 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 alternately idealizes and undervalues others, including potential romantic partners.
