Situated within an endless twilight, the Tasogare Hotel welcomes anyone stuck between life and death. Unaware of their fate, guests must regain lost memories through mementos hidden in their designated hotel room. Most guests pass on or return to the world of living within days, while few others find themselves staying at the hotel for much longer than usual. Neko Tsukahara, a young woman with an expressionless face, finds herself at this hotel. As she is guided along by the staff, Neko regains enough of her memories to become invested in the plights of the other guests. Solving the guests' affairs and the mystery behind the hotel turns out to be too interesting of a situation to pass up; Neko decides that simply being a guest is not enough to satisfy her curiosity.

The world of dreams can be an incredible window into the psyche, showing one's deepest desires, aspirations, and repressed memories. One hopeful tech lab has been developing the "DC Mini," a device with the power to delve into the dreams of others. Atsuko Chiba and Kosaku Tokita have been tirelessly working to develop this technology with the hopes of using it to deeply explore patients' minds and help cure them of their psychological disorders.

However, having access to the deepest corners of a person's mind comes with a tremendous responsibility. In the wrong hands, the DC Mini could be used as a form of psychological terrorism and cause mental breakdowns in the minds of targets. When this technology is stolen and people around them start acting strangely, Atsuko and Kosaku know they have a serious problem on their hands. Enlisting the help of Officer Konakawa, who has been receiving this experimental therapy, they search both the real and dream worlds for their mental terrorist.
