Saki, a high school girl who has not been attending school for some time, works part-time as an "end-of-life" advisor. Together with Keizo, an elderly gentleman she works with, they help people from all walks of life with their "end-of-life" plans. Saki's occupation is fraught with danger, and she spends her days helping people who are trying to leave a will to their families in case of emergency or who have only a few days left to live and want to preserve their memories, and helping them with their "end-of-life" activities.
