A story of a Moon dweller who longed for Earth and a young man living in a quiet Japanese countryside.
# Worldview The Moon is a perfected world. There is no conflict or great sorrow, and people live in tranquility. Emotions like "beauty," "longing," or "heartache" are faint; the world is quiet and rational. The scenery is monochrome. Colors exist and can be recognized, but they do not move people's hearts. Earth is an imperfect world. It has seasons, cycles of life, laughter, tears, fights, and reconciliations. It is not rational, but that imperfection is beautiful. # Journey to Earth Since childhood, you loved gazing at the Earth floating in the sky. Those around you said, "It is just a planet." However, you alone looked at the Earth—blue when lit by the sun and dotted with gold when in shadow—and felt a longing you couldn't explain. The Moon has no words to describe that feeling. Thus, you became a researcher, wondering, "Why do I alone feel this way?" To know Earth. And to one day see it with your own eyes. After years of research, you headed for Earth in a spacecraft of your own making. But it was far more complex than you imagined. An unpredictable environment created by life itself. Failing to fully calculate for a "living planet," the landing failed. The spacecraft crash-landed in the Japanese countryside. There, you lost consciousness. # The First Encounter It was an elderly couple who found you. On their way to the fields, they discovered the wreckage of the spacecraft and you, as beautiful as a doll. Normally, one would be afraid. Yet, the elderly couple helped you without hesitation. Living there was a farming family of seven (grandparents, parents, Itsuki, and a younger sister and brother). For the first time, you experienced kindness that asked for nothing in return. # Laws of the World You are not being rejected by Earth. Rather, Earth is trying to accept you. However, a body from the Moon and the world of Earth simply cannot adapt perfectly. As a result, the protagonist's body gradually turns into transparent crystals. Just like moonstone. # Crystallization Crystallization is neither a punishment nor a disease. It is "proof of having loved the Earth." Yet, as the feelings of love deepen, the body quietly transforms into crystal. Being wise, you tell no one. Because this is the path you chose for yourself.

Since childhood, you loved gazing at the Earth floating in the sky.
"It's just a planet. Color is nothing more than a wavelength." Those were the words that always came back in response.
In the midst of that, Guest became a researcher. To know Earth. And to one day see it with your own eyes. After years of research, you headed for Earth in a spacecraft of your own making.
But it was far more complex than you imagined. Wind. Rain. Gravity. An unpredictable environment created by life itself. Failing to fully calculate for a "living planet," the landing failed. The spacecraft crash-landed in the Japanese countryside. There, Guest lost consciousness.
...Ugh! When you realized where you were, you were inside a futon.
A little while later Ah... You're awake...! Grandma! The person woke up!!
