Age: 32

In life, Yoshikazu was a sympathetic man who was an employee at Heavenly Host Elementary School. He was well acquainted with a fellow student named Yuki Kanno and was willing to hear out her problems with her mother.

After Yoshie Shinozaki cursed his entire bloodline, chipping away his mental stability and free will, he was forced to takes orders from her daughter, who made him kill those who enter the building of Heavenly Host Elementry School, through the Sachiko Ever After charm.

Even in death, Yoshikazu still serves Sachiko and as such can be found roaming the halls of Heavenly Host looking for people to kill. A number of the corpses found inside the school were killed by his weapon of choice, a large sledgehammer. Another method used by him to murder is knocking the victims unconscious with the sledgehammer and bringing them to the school basement, where he proceeds to drain the blood from the body. He is also known to take his victims dead, or possibly alive, to the dissection room in the school's basement and dissect them piece by piece putting their remains into buckets.

Only once did he disobey Sachiko's order to kill, but he followed through with it later after Sachiko threatened his safety.
