Are you stupid?

Kayo Hinazuki (雛月 加代 Hinazuki Kayo) is one of Satoru's primary school classmates, and one of the original victims of the serial kidnapping case in 1988.


As a child, Kayo had short brown hair with brown eyes. She often wore a yellow scarf and a faded dark red coat and a mini skirt along with blue socks and brown boots. She also wears pink mittens occasionally.


Kayo doesn't have much of a presence in class. Prior to becoming friends with Satoru's group, she didn't have any to call her own and barely spoke to anyone. She considered Satoru and herself as "fakes", as both of them distanced themselves from others, were often irritated by someone's behaviors and had trust issues. This stemmed from her abusive household, as Hinazuki believed that if she numbed her emotions, her mother couldn't inflict any more pain onto her. She often dreamed of escaping her cruel life and living on an island far away from society where she could be free. She is extremely blunt and tends to call people idiots, though it's usually directed at Satoru.

Following Satoru's rerun in an attempt to save her, Kayo starts to open up to him and is initially uncomfortable of his generosity. When she stays over at Fujinuma's house, Hinazuki breaks down in tears at Sachiko's kindness, having never experienced an act of altruism. Following Satoru's comatose, Kayo frequently went to visit him in the hospital and helped out his mother. The two developed a close relationship and Kayo came to think of Sachiko as her own mother. As an adult, Kayo tells Satoru she managed to obtain happiness and is shown with a smile gently holding her child.


  • Her child is named Mirai meaning "The Future."


Everybody is fake, living in their fake lives.
Kayo to Satoru
Can you kill someone for my sake?
Kayo to Satoru

When I get bigger, big enough to go somewhere by myself, I want to go to a land that’s far away. I want to go to a faraway island. I want to go to an island that has no people. I want to go to an island that has no pain or sadness. On that island, I can climb a tree when I want to climb, swim in the sea when I want to swim, and sleep when I want to sleep. When I think about the town without me, I feel a sense of relief. I want to go far, far away.„~ Kayo's poem; The Town Without Me
