One day, Adachi-san is approached by the editor-in-chief of a female magazine with a proposal to run a series about throwing away a personal belonging in each issue, based on the theme of parting with possessions and living more comfortably. That night, Adachi-san falls asleep like always. But a mysterious girl and the personification of the items that she has held onto appear one after another in her dream, asking to be thrown away.
