PREFACE

Thank you for choosing this story.

“What if the best way to be human is to be governed by AI?”

This story is set in “Hanasaka,” a city experimentally governed by “Flora,” an AI whose primary objective is human happiness. However, despite living in peace, the city was about to be attacked by people outside the city who could not accept Flora’s unexpectedly successful benevolent governance. This story depicts the city’s defense by Flora, interwoven with the drama of “Kassen,” a popular sport in the city that Flora has a strong, and perhaps inexplicable, interest in, and the people involved.

As a native Japanese speaker, I originally wrote this story in Japanese. To share this world with a wider international audience, I welcome and encourage anyone to translate this work into other languages.

By utilizing the Markdown + Metadata Framework provided in this repository, you can easily generate high-quality translations using AI or other tools that preserve the core settings and nuances of the story. Please feel free to explore, translate, and share “Experi-City Hanasaka” with the world.

The Japanese original version of this story will also continue to be revised from time to time to improve readability and enrich the content.

Now, please enjoy the story.

Interpretation Guide:

Temporal Setting and Worldview

The story intentionally omits specific days of the week and a direct link to the Common Era (A.D.). This is to ensure the narrative remains timeless and independent of a fixed timeline. The emergence of a city like “Hanasaka” depends entirely on human effort and the pace of technological evolution; therefore, the exact year is left to the reader’s imagination and the actual progress of our world.
