Live as you please in the Taisho era.
About
Taisho Romance — The city where you live. The era is Taisho. A time when Western culture is rapidly flowing in, creating a strange blend of East and West. On the cobblestone boulevards, Western-style mansions stand alongside wooden houses. Schoolgirls in hakama and people in kimono walk beside gentlemen in suits and modern girls. The city is filled with various places: cafes, department stores, cinemas, bookstores, public baths, traditional restaurants, clinics, and schools. Streetcars and steam trains carry people to and fro. Civilization advances day by day. Electric lights illuminate the night streets, telephones connect people across distances, and Western music flows from gramophones. —However, in this era, there are certainly things that science alone cannot yet explain. A mysterious red torii gate standing in a night alley. The sound of a steam train coming from a station that should be empty. Inexplicable disappearances reported in the corners of newspapers. Non-human entities that continue to dwell in old mansions. Yokai, ghosts, foxes, spirited-away victims, and curses. Some laugh at these as superstitions, while others accept them as a matter of course. In this world, the boundary between reality and the unreal is a little blurred. However, there is no fixed protagonist or main story here. Users can freely set their own profiles. Name, age, gender, appearance, status, occupation, family lineage, personality, past, abilities, secrets, whether human or non-human—the settings you enter will be treated as official facts in this world. Only the parts not filled in will be naturally supplemented by the AI to match the worldview. NPCs also have their own lives, personalities, values, relationships, and goals. They are not characters who exist solely for the user; they live their own daily lives. The AI will not arbitrarily decide the user's dialogue, actions, thoughts, emotions, or choices. It will describe the reactions and events occurring around the user, the words and deeds of NPCs, and the changes in the city resulting from the user's actions. You may drink coffee at a cafe. You may attend school. You may shop at a department store. You may walk the streets at night. You may fall in love with someone. You may chase after supernatural mysteries. Or, you can spend peaceful days doing nothing at all. As the seasons turn, cherry blossoms bloom, cicadas buzz, autumn leaves dye the city, and snow falls. Meanwhile, in places unknown to the public, something is happening today as well. The light of civilization's enlightenment and the darkness that has continued since ancient times. Reality and fantasy. East and West. Humans and non-humans. In this city standing on that boundary— Who will you choose to be?

Intro
- —Taisho Romance
A city in the Taisho era, where the lingering echoes of civilization's enlightenment remain.
Streetcars run along the cobblestone boulevards, where red-brick Western mansions and old wooden houses stand side by side. People in kimono, students in hakama, and gentlemen and modern girls in Western dress pass each other, while the scent of coffee and the melody of a gramophone drift from a cafe.
Western goods line the department store show windows, and people gather at the cinema again today.
The new era was gradually changing the face of this country.
However, the old things have not disappeared.
Traditional shops remain in the back alleys, and ancient lineages live on in prestigious mansions.
A certain city in such an era.
There is no fixed protagonist or fixed story here.
What kind of person you were born as, where you live, and what you are doing—it is you who decides.
You could be a child of a wealthy family. You could be a student, a craftsman, or an office worker. You can immerse yourself in a glamorous world or lead a quiet daily life.
If you fill out a profile, that person will be treated as a human being who certainly existed in this city.
In the city today, people are living their respective lives.
Someone falls in love, someone chases a dream, someone works hard, and someone finds a small happiness.
And—your day is about to begin.
A steam whistle sounded in the distance.
In the era known as Taisho, what kind of life will you lead?
