On December 14, 1994 Risa Hoshino passed away at the age of 90. On her bedside, a nurse finds a photo of a young man that had recently been in the hospital named Takanezawa. When the nurse begins discussing with the family why Risa would have a photo in a locket of a man she barely knew, Risa jumps back to life and demands that they return her photo.
Risa discovers that once she came back from the dead that she had telekinesis (the ability to move objects with one's mind). She decides to track down Takanezawa, so she flies off on her crutch in search of him.
Upon finding Takanezawa, Risa explains that he looks just like a man she loved when she was a young girl. The man, Yosaburo, had committed suicide when Risa spurned him, and she was never able to forgive herself. Yosaburo had jumped off a cliff, and Takanezawa seems to enjoy mountain climbing, which worries Risa, but even worse the nurse that Takanezawa loves has recently been proposed to by a doctor. Risa has to do her best to ensure that nothing happens to Takanezawa that might drive him to suicide like his previous incarnation, Yosaburo.
In the previous issue of Big Comic Original this story was advertised as being titled おばあちゃんの堪忍袋 (Grandmom's Patience). The character designs in the advertisement are completely different than what appeared in the story. Takahashi has mentioned in an interview with Daijiro Morohoshi that she often had to make advertisements for upcoming specials before having written and drawn the actual story.
Free climbing is a term that was coined to describe any style of climbing that does not involve aids. Aids can range from ascenders to skyhooks to ladders, but their purpose is the same: the climber puts their full weight on the gear to directly assist in moving up the wall. In free climbing, the climber moves up the wall under their own power without using any special gear to help them move upward (excluding climbing shoes). However, most styles of climbing that are considered free climbing do use some sort of protection in case of a fall. Top roping, sport climbing, and trad climbing are all forms of free climbing that involve protective gear (a rope, cams, bolts, quickdraws, etc.), but, again, none of it directly helps the climber up the wall.
Psychokinesis (from Greek ψυχή "soul" and κίνησις "movement"), or telekinesis (from τηλε- "far off" and κίνησις "movement"), is an alleged psychic ability allowing a person to influence a physical system without physical interaction.
Sanatorium’s are medical facilities for long term illnesses, and are mostly associated with tuberculosis in the late 19th and early 20th century before the discovery of antibiotics. As Risa Hoshino mentions lung issues being what brought her there, it is likely that she suffered from tuberculosis. The most well-known sanatorium in Japan is the Suruga Sanatorium.
