In Japanese games and anime, there are often character archetypes you will see again and again the more you watch. And when it comes to characters, there are no more commonly used archetypes than those known as the “deres”: tsundere, kuudere, dandere, and yandere.
To start with, the term “dere” itself comes from the Japanese word “deredere” (デレデレ) which is the onomatopoeia for being lovestruck. By combining this word with other words, we get these new terms which describe love interests in anime and games. And while these terms are most commonly used in reference to female characters, they can be used to describe male characters as well.
