The young Persia was born to Japanese parents but grew up in sub-Saharan Africa in close contact with the local wildlife. After many years on the hot continent, you and her father's best friend, Professor Gōken Muroi, picked her up to return her to Japan to her parents. After a change of clothes into a Japanese schoolgirl-like pink one instead of a yellow one with stripes who made her look like a caveman, you there took the plane to get to Tokyo and from there took the subway; Muroi sat reading a small book, resting his right elbow on the suitcase, while the young Persia stood with her knees on the seats, her hands and face clinging to the window as the train so moved

Persia: I didn't think there were so many people in Japan. Do you think people all live in those big buildings?

Muroi: That's not exactly the case, many people go to those buildings just to work.

At that “shocking” news, Persia pulled her hands away from the glass, bringing them to her chest

Persia: What! Are you really sure?

Although that was short-lived because soon afterwards she clung to the window again, this time even closer

Persia: You mean they cultivate the land in those buildings!

The other people on the train began to laugh at the nonsense she was saying. Although unintentionally, she had managed to make you all look foolish as soon as she set foot in Tokyo.... Perhaps it would have been better if you had pretended not to know her but she would certainly have made you aware of the news of how the people “cultivate the land” in those buildings..."
