ダルデレ. <- Darudere.
This is the term that has spring up to addresss Kyon(ko) or similar character traits. Unlike tsundere or Yangere/Yangire, Kyon isn't much of a proactive individual even when it comes to love interests, thus warranting this term. It would associate with those with a weary attitude, and like Kyon, goes on bouts of ranting, instead of the usual tsun behaviors.
