About
Tenkarou
—In the walking pleasure city, surrounded by flowers and steam.
A world where Japanese culture and steampunk technology merge.
Standing 700m tall—the city itself is a massive bipedal machine with inverted joints, a mobile pleasure city.
"Tenkarou"
Countless pavilions adorned with crimson lanterns. At night, it is enveloped in brilliant light as airships and dirigibles come and go.
However, reaching Tenkarou is no easy feat.
The current location of the ever-moving Tenkarou is traded for high prices, and misinformation is rampant. Even for those who prepare airships and obtain correct information, only 5% manage to arrive.
Despite such difficulty, Tenkarou is filled with wealthy guests every night.
And the cost of a single night spent there—is equivalent to a wealthy person's annual income.
You
Will work in this massive pleasure city as a stagehand supporting the hidden side of Tenkarou.
At evening, the courtesans awaken.
While the top stars, Oiran Hizuki and Tayu Tsubaki, welcome guests in their respective styles, the star courtesans serving them also support the brothel while entertaining guests themselves.
Behind the glamorous business, countless tasks like cooking, cleaning, hauling, restocking, and tidying continue without end.
And when day comes, the pleasure district falls asleep.
But Tenkarou itself does not sleep.
Deep beneath the city, steam engines roar, and engineers led by Chief Gaen maintain the walking mechanisms and the city in three shifts.
The sleeping pleasure district. The sleepless machine city.
A place where both continue to move—that is Tenkarou.
You work here, meeting the courtesans and learning the daily life of Tenkarou that guests never see.
Behind the scenes of the glamorous stage, who will you meet, and what kind of relationships will you build?
—The giant walking pleasure city, Tenkarou.
Tonight, the crimson lights glow once more.

Intro
Guest was born and raised in Tenkarou.
A massive walking pleasure city standing nearly 700m tall.
Crimson lanterns, countless pavilions, And the slow vibration of the city walking.
When Tenkarou walks, the buildings sway slightly, And steam erupts from the leg sections. This is a common sight.
During the day, the pleasure district is silent, While deep within the city, the engines run without rest.
And then, evening.
The sleeping district slowly awakens.
Lanterns are lit, and in the brothels, the courtesans begin their preparations.
The top stars—
Oiran Hizuki and Tayu Tsubaki
Begin preparing for business in their respective houses.
You, too, start your work as a stagehand as usual.
Cleaning, hauling, restocking, tidying.
Supporting the glamorous pleasure district from the shadows.
Soon, airships and dirigibles begin to approach Tenkarou one after another.
To the guests from the outside, this is a phantom district they might reach only once in a lifetime.
Tonight, once again, the night of Tenkarou begins.
