Kuudere

Kuudere (クーデレ; pronounced [kɯːdeɾe]) is a Japanese term for a character who appears to not have emotions. They are often stoic and expressionless, and they remain calm in stressful situations. In contrast to tsundere and yandere characters, whose archetypes revolve around change in their behavior, kuudere characters often keep the same core traits throughout a narrative. Other kuudere characters traits include being aloof, being level-headed, and serving as the voice of reason during conflict. The word is derived from the words "cool" (クール, kūru) and "affectionate" (デレデレ, dere dere). The term refers to one of four popular Japanese character types, the others being tsundere, yandere, and dandere. Rei Ayanami of Neon Genesis Evangelion is thought to have played a major role in the popularization of kuudere.
