Third person POV
Later, at 7:36 p.m., Hoshi and his group arrived back at Osaka City and got off the train, before leaving the station and going to the Takada estate on foot. At 8:23 p.m., all of them are now eating with Hoshi and Mariya's grandparents and relatives at the estate's main house. They shared their daytime adventures at Kobe City to Hoshi and Mariya's relatives, who were amazed by their fun time in the nearby city.
Then, after dinner and helping with the nighttime chores, Hoshi was looking at Kuro in the bathroom's mirror. "Hoshi," Kuro started the conversation, "I had a hunch that the mysterious ghost woman at Kitano-cho in Kobe City was a yokai."
"Is that so?" replied Hoshi back.
Kuro then nodded. "Yes, probably…let's research about that later."
Hoshi eventually agreed. "Yes."
And so, after that, both of them are at the main house library, researching about the mysterious woman through Japanese folklore books. After much searching, both of them found a possible yokai: Utsurobune. According to the source materials, it is a yokai that had landed in Kobe City a few hundred years ago in a strange-looking ship that no one had seen before. That vessel had a saucer-like shape according to the photos of the paintings printed on the pages of the books. Hoshi and Kuro were stunned by them, and Hoshi said that it was like those spaceships by aliens. Kuro nodded, having known about these strange anomalies that couldn't be explained by science. But the first account was probably one that was said to have been spotted more than a thousand years ago, and that girl claimed to be the daughter of the Chinese Ming Emperor. Other sightings speculated people from other countries, from Russia to India. Some theories postulated in the books suggested that those might be UFOs or time-travelers from the future at a time when globalization wasn't a thing yet.
After all that reading and researching, Hoshi and Kuro were left stunned, and Kuro said, "Well, I am surprised…these sightings were a thing before a thing called globalization was a thing." Hoshi then nodded. "Yeah…" Both of them eventually decided to go back to Kitano-cho in Kobe City to investigate it tomorrow morning. So, after reaching that resolution and cleaning out their mess at the main house library, Hoshi and Kuro turned off the lights and left the library, going back to Hoshi's bedroom to rest up for the night.
