There were a few reasons why the last episode of the Night of the Hundred Demons did not explicitly mention his grandfather: The story of the 100 Demons of the Night is set in Japan, and Japanese culture places great emphasis on family and kinship. Therefore, the appearance of the grandfather in the story may be considered a challenge or violation of family tradition. The story of 200 Demons at Night was mainly about a series of adventures between a beautiful girl and her friends at night, and there was not a single male character among her friends. Therefore, if the father or grandfather of the protagonist, Beautiful Yaksha, appeared in the story, it might be seen as a deviation from the theme of the story. It was also possible that the director or screenwriter thought that it would be more interesting and fascinating to let the main character tell the story of her grandfather instead of letting the character directly realize the plot. In summary, there were many different reasons why he didn't say that he liked his grandfather in the last episode of the Night of the Hundred Demons.
