Student council president at Juu's school. Kaori claims she once "killed" someone by not returning his love, resulting in his suicide.
It is later discovered that Kaori had once dated Ichiko's brother but dumped him in favor of another man who was destined for great financial security. This causes Ichiko's brother to commit suicide, which indirectly sets off the chain of events within episode 2. She is later harassed by Ichiko, culminating in a confrontation where Ichiko's attempts to make Kaori cut off parts of her own body. The stress of having her true past revealed and the trauma of being attacked by Ichiko cause Kaori to have a mental breakdown. She attempts to kill Juu by pushing him in front of a car to obtain his "happiness". However, the car swerves to avoid Juu and instead crushes Kaori against a wall, resulting in her death.
