Cursed Warrior

The was a ghostly samurai who supposedly came from the Land of Birds.

History
It was believed to be the ghost of the country's former daimyo, Owashi. Ever since Owashi was discretely poisoned by the Watari ninja Oki (taking the guise of Moso), the Cursed Warrior had been haunting the Land of Birds and attacking Moso and several other of its inhabitants. Overtime, the people began to suspect Komei, the Land of Birds' tactician, was behind the Cursed Warrior. During the first battle with Team Neji, after being attacked for a short while, vanished completely, leaving the empty armor behind. Also, Neji said that there was no human presence inside.
