Tsundere, Yandere, Kuudere, Yangire, and Dandere are five different types of personalities (for girls and boys) that are often used in anime, manga, etc. You can recognize them by their behavior. (In the examples are the characters that I know of.)
It’s a person with an attitude. Tsundere Usually they start with a harsh personality, but slowly they start to show their soft side. He acts very mean, sometimes violent, but inside he can be very sweet. They’re very moody.
Tsundere (ツンデレ, pronounced [tsɯndeɾe]) is a Japanese term for a character development process that depicts a person who is initially cold (and sometimes even hostile) before gradually showing a warmer, friendlier side over time.
The word Tsundere is derived from the terms tsun Tsun (ツンツン) (‘to turn away in disgust or anger’) and dere (デレデレ) (‘to become affectionate’).
Originally found in Japanese bishōjo games, the word is now part of the otaku moe phenomenon, reaching into other media such as maid cafés, anime, manga, novels, and even mass media. The term was made popular in the visual novel Kimi ga Nozomu Eien
They can be described as stalkers. These people can look cute and innocent, but they can be highly dangerous. They would kill or attack anyone that would stand against or in the way of their love. These types of people are psychotic and insane.
They can be:
Possessive: Kills their loved one, so he or she will not fall in love with someone else.
Obsessive: Kills the competition so she or he can be closer to their love.
Examples: Gasai Yuno (Mirai Nikki)
Sutcliffe Grell (Kuroshitsuji)
Sonozaki Shion (Higurashi no naku koro ni)
Yandere (ヤンデレ) is a Japanese term for a person who is initially very loving and gentle to someone (or at least innocent) before their devotion becomes destructive in nature, often through violence and/or brutality.
The term is derived from the words yandere (病んでる) meaning a mental or emotional illness, and deredere (でれでれ) meaning to show affection.
Yandere characters are mentally unstable, and are sometimes incredibly deranged and not mentally sane, often using extreme violence and/or brutality as an outlet for their emotions.
The character, for the start, seems to be cold, quiet, serious, and unemotional, but she/he can be very sweet and soft on the inside.
Examples: Tachibana Kanade (Angel Beats)
Sakagami Tomoyo (Clannad)
Iwasaki Minami (Lucky Star)
Shiina (Angel Beats)
Kuuderes often speak in a calm monotone and seem unaffected by the world around them. They never seem to be overly happy, excited, or surprised – just as they never appear sad, annoyed, or angry. Extreme examples may even seem to be completely emotionless.
It is used to describe characters who always remain calm and composed. Though they act serious on the outside, they often have a very good, sarcastic sense of humor.
In the beginning, Yangire seems to be friendly, nice, and cute, but later their personalities change and they become aggressive. It can be a result of mental illness. It’s similar to Yandere, but it isn’t a result of love obsession.
Examples: Ryuugu Rena (Higurashi no naku Koro ni)
Yangire (also referred to as “cute and psycho”) is a Japanese term used to refer to normal people who suddenly become violent, sometimes due to past trauma.
Yangires are very similar to Yanderes. Both are people who suffer from a personality disorder and can easily become violent and extremely dangerous.
However, Yangires are far, far more chaotic, and they can be much worse than Yanderes. A Yangire is a character who snaps suddenly out of jealousy, irritation, or similar.
Very quiet person, that rarely speaks and it’s very shy. This character avoids contact with other people until the right person comes along. If they get used to someone she/he gets more confident.
Examples: Ichinose Kotomi (Clannad)
Hyuuga Hinata (Naruto)
Danderes often want to be sociable but are either too embarrassed or scared of getting hurt.
They tend to fear that saying the wrong thing might get them into trouble, or some other socially awkward situation, so they say nothing to be on the safe side.
In nearly all cases, however, they overcome this when befriended and tend to reveal their true selves – sweet, gentle, and very friendly people – especially with the ones they love.
