Deredere
The deredere is a total sweetheart from start to finish—cheerful, affectionate, and devoted. No mood swings, no murder, just wholesome love and maximum moe. Think Tohru from Miss Kobayashi’s Dragon Maid. They’re the “wife material” of the anime world, the kind you want to cuddle up with on a rainy day.
Also see tsundere, yandere, etc.
