Plot
Pajama na Kanojo (which can be loosely translated as "She in pajamas") follows the story of Keisuke and Makura, two childhood friends who have grown up together. One day, when witnessing a conversation between Keisuke and beautiful senior student Yuki, Makura becomes jealous. Later that day she argues with Keisuke and runs away from home. When it becomes late, Keisuke's mom tells him to go find her as she has not returned home. Keisuke goes reluctantly and is able to find her, wearing only pajamas, in a sunflower field where they used to hang around as children. As they go back, Keisuke receives a panicked phone call from his mother telling her that Makura is in the hospital unconscious. Only then he realizes that she is floating in the air.

In the hospital, Keisuke learns that Makura has developed symptoms similar to those of the Sleeping Beauty in the fairytale: she is soundly asleep, but cannot be awakened, and also has a small wound in the pinky finger of her left hand. He also seems to be the only one to see or hear the floating Makura, who does not seem too troubled by the fact.

Keisuke starts to look for clues to return Makura back to normal, and finds out that the doctor attending her had a similar case before. The doctor leaves, however, although he promises to help Makura when he returns. When Keisuke looks for some information in the doctor's office he runs into Yuki again, who happens to be the doctor's granddaughter.

Yuki starts helping Keisuke, although she does not know anything about Makura or about why Keisuke is so interested in her grandfather's research. She also starts developing feelings for him. Keisuke seems to have feelings for her too, but is also increasingly confused as he starts looking at Makura with different eyes than those of a friend.

Makura is oblivious regarding the circumstances that led her to her condition, but the disease seems to be related to a mysterious woman called Yoshika Midzuki, who suffered the same condition and was a patient of Yuki's great-grandfather. Midzuki appears in front of Makura to remind her of her "vow", and tells her that when the mark in her finger surrounds it completely she will die, as she requested. Makura has made no mention of this to Keisuke, fearing that he will feel guilty for it.
