Chihiro closed her laptop and turned to see her husband standing behind her.
"Done?"
"Yup" she replied.
She had finished typing out the story, her story, well, what happened AFTER she left the Spirit World when she was ten. She decided to get it down for her great grandchildren to read.
She only had one daughter, but sadly the girl was not with her. Ava had been conceived and born in the Spirit World, so she had to stay there. Chihiro intrusted her to Lin, who took very good care of her. She felt bad, not being with her daughter, but she knew that if she stayed there too long, she would disappear and no amount of food could prevent it.
She had four sons after Ava. They all knew of the story, they all knew of her sister. They all visited the Spirit World with Chihiro to see their older sister. Children were more attuned to that world than adults were, so they didn't have a hard time believing it. Their children did the same.
Chihiro knew that she was getting old, and she was getting sick. She didn't tell Haku the extent of it, she knew that he couldn't do anything and would just worry too much over her.
One night, Chihiro didn't wake up. As she floated out of her body, she watched as Haku jolted awake. He tried to shake her, but her hand fell limp. Nodding, he soon joined her.
"Haku..."
With a jolt she realized that they were both in their young adult bodies. He took her hand and led her towards the Spirit World. They were greeted with open arms.
They spent the rest of eternity there, and things were perfect.
