Yoshikazu Yanagihori (柳堀 ヨシカズ,Yanagihori Yoshikazu?) (1941 - 1974) is a recurring antagonist in the Corpse Party series. He is the son of principal Takamine Yanagihori of Heavenly Host Elementary School and as such is believed to have worked there with his father.
Yoshikazu's design is very much like that of a zombie. He wears a brown jacket and a torn-up green shirt, both of which are covered in blood. He has black hair and red eyes. He usually speaks in long moans.
He sometimes takes orders from Sachiko, who controlled him after the latter's mother cursed his entire family, which reduced his mental stability and will, to kill those who enter the building through the "Sachiko Ever After" Charm. He usually kills trespassers through 3 ways: 1. He strikes hard at the head or back with a sledgehammer, 2. He uses the sledgehammer to knock them unconscious, and brings them to the school basement, where he proceeds to drain the blood from the body, or 3, which is by far the most painful, is #2 except that instead of draining out the blood, he proceeds to amputate body parts off and take the insides to place in a bucket. Only once did he disobey Sachiko's order to kill, but he followed through with it later.
