Kazu Ishii

Kazu Ishii (石井カズ, Ishii kazu) is a second-year student at Fujimi Academy and the friend of Okada. He attempts to help Shizuka Marikawa escape during the Outbreak.

About
An assistant of Shizuka Marikawa, he helped her try to heal the students that had been bitten by Them. When a hoard of Them broke through the windows, Kazu was bitten and then was killed out of mercy by Saeko Busujima.

Appearance
He was a rather tall student with dark brown hair and brown eyes. He was seen wearing blue, round-framed glasses until his death.



History
Before the Outbreak, Kazu was a normal student at Fujimi Academy in class 1-B. He aided the school nurse Shizuka Marikawa with several menial tasks such as carrying her medical supplies while she carried his notebook.

Personality
During the brief moment he was shown, Kazu was portrayed as a very nervous person. However, he showed signs of bravery when he attempted to defend Shizuka and told her to run when he was bitten. He also consented almost immediately when Saeko asked if he would allow her to kill him.

Plot
Kazu is first seen in the nurse's office with Shizuka, beating down his friend Okada while begging for forgiveness. When Shizuka comments on how this reminds her of an old horror film, Kazu tells her to hurry and gather all the supplies she can so they can escape. Suddenly another group of Them breaks in and bites Kazu's arm as he tells Shizuka to run. Shizuka asks for his name as he falls to the ground and is swarmed by Them. Saeko Busujima than kills all of Them, saving Shizuka and sparing Kazu from being turned immediately. She places a hand on his shoulder then introduces herself. After asking his name, she  tells him that he knows what happens when they get bitten and asks Kazu if he wants to die so his family and friends won't have to see him as one of Them. He consents fairly quickly, and Saeko smashes his skull and kills him.

Later, in the manga only, during a talk between Saeko and Saya Takagi at the latter's estate, the former brings up her part in Kazu's suicide, saying that even though it was assisted suicide, no child should ever have to go through it.
