Age in Narcissu: 22
Age in Narcissu Side 2nd: 15

Setsumi has a childlike physique. She has a taciturn and stoic kind of personality. She loves cars and is knowledgeable about them. Because of her terminal illness, she has no friends and is always seen alone. After many years of receiving treatment, she became totally desperate about everything - life or time, or each day passing doesn't matter to her anymore. It is just like she stated once: "My time came to a halt". Everything is very painful to her because she was left behind alone as the world around her continued to move on.

In Narcissu, she metAtou Yuu, a new resident of the hospital's 7th floor, the hospice, and for a short moment did she come to know something like hope.<hidden by spoiler settings>
