Tsundere (ツンデレ?) (pronounced /(t)sʌnˈdɪə(r)/ in English or /t͡sun.de.ɽe/ in Japanese) is a Japanese concept of a character archetype which describes a person with a conceited, irritable, and/or violent personality that suddenly becomes modest and loving when triggered by some sort of cause (such as being alone with someone). Tusndere means can also describe a contradictory personality which is good-willed on the inside, but with a harsh attitude on the outside. Originally found in Japanese bishōjo games, the word is now part of the otaku moe phenomenon, reaching into other media such as anime, manga, novels, and even mass media. check the pictures below about tsundere
Tsundere is an Internet slang word that has a remarkable subdivision structure; usage rules vary accordingly. Therefore, the term is not elaborately defined as to what character types can be described as tsundere; the term transcends gender and species. The definition is often subjected to the creator’s point of view.
Tsundere is a portmanteau of the two words tsuntsun (ツンツン?), and deredere (デレデレ?). Tsuntsun is defined as “aloof, morose, pointed”, and deredere is defined as “exhausted, lovestruck”. Tsunderekko (ツンデレっ娘?) is a related noun, referring to a girl with a tsundere personality. Like nekomimi, tsundere is considered a moe-inspiring character trait. The concept has received increasing attention in Japan, with a tsundere cafe opened in Akihabara[note 1] and tsundere-themed products released (like Tomy Co.’s portable television set),[note 2] and the concept increasingly reflected in recent anime, from an extended discussion of the meaning of the concept and its origin on the internet in Lucky Star’s Lucky Channel segment to merchandise for The Melancholy of Haruhi Suzumiya classifying the characters according to tsundere-ness.
