Hoshino was a fictional world, so there was no definite and accurate novel catalog. However, according to some well-known novels of this world view, some related novels could be roughly listed:
1 " Starry Sky Divine Tune "
2. Interstellar Sword Immortal
3. Interstellar Magician
4 Space Colonists
5. Interstellar Behemoth
Interstellar Pirates
7. The Interstellar Fugitive
8 Star Empire
9. Interstellar Infernal Affairs
10 " Heart of the Starry Sky "
These novels all appeared in this fictional world view and had a certain degree of influence. However, due to the uncertainty of Hoshino's worldview, the specific plot and content of these novels were also different.
I'm not entirely sure as there could be many different stories within Miyako Visual Novel. It might be about the character Miyako's adventures, relationships, or experiences in a fictional world. Maybe it has elements of mystery, drama, or romance.
Since I don't have detailed information about Miyako Visual Novel, I can only assume that Miyako is one of the main characters. There might be other characters like her friends, family members, or love interests who play important roles in the story.
One possible theme could be about family and new beginnings. With Miyako being pregnant, it might explore how she and the other characters adapt to the upcoming addition to their 'family' in the fanfiction world.
There were novels similar to Hoshino Sakura's Journey to Play. You can take a look at Ting Mingying's "I Only Accept Female Disciples in the Rune Land". It was also a light novel and a derivative doujinshi novel. It told the story of the male protagonist living happily with a group of female disciples in the universe. I hope you like this fairy's recommendation. Muah~
One great miyako x ken fanfic could be 'The Adventure of Miyako and Ken'. It focuses on their journey together in a magical world. They face challenges and their relationship deepens as they overcome obstacles.
