"The Dullahans"

"I can't believe I read about you in my history books. They said you disappeared after being beheaded." "Well that is weird. I thought for sure they would have just said I died."

This pair is, as it stands now, inseparable. They are a Dividual, if you will. Sometimes they grab each others heads by mistake, but it usually all works out in the end. Whenever a fight breaks out, they tend to send their bodies out to fight while their heads give commentary on the whole ordeal. They somewhat frequently make remarks suggesting they aren't from this world, but that they are from the same Otherworld as each other.

Their shared traits include, but are not limited to: the detached head (of course), with colored fire escaping from the neck wound (on both ends); their mouths open from ear to ear, granting them an eerie, cheekless smile; pasty skin with vaguely pointed ears; and colorless irises.
