Kuudere characters in anime are some of the calmest, rarely showing emotions and instead remaining in a constant state of stoicism. While a tsundere character in anime might hide their true emotions, kuuderes aren’t hiding anything they really are that calm. Kuudere characters aren’t devoid of emotion, however. There are rare moments where a kuudere character will break, showing a brief flash of feeling. These moments are usually more fulfilling because of their stoicism, highlighting how important the situation must be if it made a kuudere care.
