The main character, “Takumi,” was in a coma after a traffic accident.
When he woke up from his sleep, he was admitted to a strange hospital reminiscent of an old-fashioned Western-style building.
And he had the mysterious ability to see the past voice “voice” of the place.
Even so, Takumi often sees the illusion of the XX scene with his nurses “Ao” and “Aoi” and the newspaper reporter “Aki”, contrary to his will.
He is confused by the mysterious phenomenon and consults with the director, but he is told a mysterious word.
