Kazahaya was found dying in the snow and was saved by Rikuou Himura. Ever since then, he has been working as an employee for the Green Drugstore and living with Rikuou. Whenever he touches objects or people, he has the ability to see their memories. His appearance has been described as more feminine, leading him to be asked to cross-dress for multiple assignments. He has an expressive and straightforward personality, which makes it easy for others to tease him. Kazahaya is also very naive. Before meeting Rikuou, he did not attend school and was completely useless at housework.
