Haraguro

Haraguro characters are characters who are good at displaying their appearance of being friendly, approachable, kind and refreshing in public; however, this is a front to hide their darker, sadistic, and twisted personality. These characters are very ambitious and are willing to achieve their goals no matter who gets in their way.

Despite the negative connotation, not all haraguro characters are villains or are sociopaths. Their motives vary very widely depending upon the character and the story.

Some haraguro characters might also fit the Yandere or Yangire archetype, but that again depends on the character.

Meaning of the Name
The term comes from the Japanese word, "Haraguroi (腹黒い)", which means "black-hearted; mean; scheming".
