was the leader of Land of Neck.

Appearance
Kōza wore basic armour with a helmet included. He had a sword sheathed at the waist. He had brown hair and a moustache.

Abilities
Kōza was able to use the summoning technique. His summon was Shiromari, a giant chameleon, which could take almost any form to lure enemies inside it. Since he had a sword, he was presumably skilled in kenjutsu.

Cursed Castle Arc
Kōza summoned Shiromari, which took the form of a castle and died some time after. Naruto Uzumaki, Hinata Hyūga and Kiba Inuzuka visited the castle in a mission, he returned in a soul form to release Shiromari in the castle form.
