This is the story that Natsuki's father, Kono Taro, often told her when she was a child.
It's hard to differentiate which parts of the story are true and which parts have been artistically embellished.
But in Kono Natsumi's memory, at the time of her grandmother's death, she seemed to have truly seen an unknown young girl, kneeling by her grandmother's side, weeping with extraordinary sorrow.
However, that was a memory from when she was four years old.
It's hard to say whether she really saw it or not.
In Natsuki's recollection, after her father, Kono Taro, finished telling the tale of the family's Zashiki-warashi, he would always use it as a jumping-off point for family education:
"Being indolent and shunning hard work will make you the kind of person the Zashiki-warashi dislikes," he would say.
"If there is someone in the family who is not ambitious, the Zashiki-warashi will frown like this and stand beside him."
