Also known as: 不気味な笑顔, 狂気な笑顔
A Smile that exudes craziness rather than happiness. Usually depicted as an extreme Smirk or as a wide open smile, both with distinctive sharp mouth corners pointing upwards. Often accompanied with a Shaded Face or Crazy Eyes to emphasize the malicious nature of the expression.
Typically seen with characters who are either Yandere, sadistic, or completely Crazy. May overlap with Evil Smile when the character is not just crazy, but malicious.
