The current Prince Akihito is quite different from the impression of Prince Akihito from Fushimi Roku's previous life. The difference is that in the previous life, Prince Akihito was still alive in 1991, whereas now Prince Akihito is already dead.
Thus, his wife, Princess Nakako, is currently a widow of Japan's royal family.
Next, Akishino Mako, who was originally supposed to be born in 1991, was born nineteen years earlier, and she was a young girl at the time of her death. She committed suicide by jumping off a building recently, and now she will forever remain a nineteen-year-old girl.
Nineteen years ago, Fushimi Roku hadn't crossed over yet! It certainly wasn't him who caused the butterfly effect, which indirectly proves that this is Japan in a parallel world...
First, Princess Nakako lost her husband, then her daughter. It's easy to imagine how sad she must be. It's understandable that she would invite a spirit medium to see her daughter one last time.
