Santa Claus (KKN)

The most bad-ass Santa Claus has ever been depicted, Kyouran Kazoku Nikki's Santa can rip off his clothes by flexing his muscles, can survive a direct hit from a Stinger and has the ability to shoot energy balls created from his hands. It seems that the only thing that can defeat him is Kyouka, the omnipotent God.

He had a falling out with his granddaughter but the Miderazaki family helped them reconcile and now they deliver presents together.
