Inori Misasagi is a high school student possessing long black hair that reaches her hips and striking green eyes. Her surname translates to "mausoleum" or "imperial tomb." Characterized as sweet, she finds enjoyment in cooking and playing the piano. She shares a past connection with Isshu Sagisawa from their childhood, a meeting he does not remember.

In the "Inori no Todoku Toki" OVA, Inori and Isshu made a significant promise to attend the Ashikajima fireworks festival together annually, marking the place where their relationship began. When Isshu declines her invitation due to work at the Narazuya Cafe, Inori attends the festival alone. During this solitary visit, she reflects deeply on their past two years spent together at the event.

Her memories trigger profound worries about the authenticity of Isshu's love for her, forming the core of her emotional journey in the OVA. After persuasion by Nonohara Haya and Shizuru Shirakawa, Isshu leaves work to meet Inori at their designated spot near a church. They reconcile and uphold their promise by watching the fireworks together, a symbolic act reaffirming their bond.

Her story centers on themes of commitment and the need for reassurance within their relationship, culminating in the resolution of her doubts through their reunion at the festival.
