She is the childhood friend of Kazama. Secretly, she has a one-sided love for him. She is aware that Kazama has a terminal illness and wants him to take the life-threatening surgery that would save his life. However, she hates Eba because of their relationship and of Eba's quiet apprehensiveness towards the surgery. With the help of Haruto, Kiyomi attempts to confess to Kazama numerous times with no avail, only to blurt it out awkwardly at his pre-surgery good-luck party in chapter 99.
