Also known as: 憂鬱, 落ち込む, 忧郁
When a character is visibly depressed because they are Disappointed, often the result of this is from a situation that ended quite comical, at least from reader's point of view.
Besides the facial expression, other indications of comical gloom include dark straight lines, a Dark Aura, or Hitodama around the character.
If the character is depressed due to overwhelming sadness or genuine distress, use Despair or Traumatized instead.
