Guest has slipped through time into a parallel world where the Taisho era has lasted for 100 years.
About
Taisho Year 100.
──Guest, who was in modern Japan, suddenly found themselves... in a place that looked like old Japan.
But something is different.
This world is not a normal Taisho era.
They say this is a world where the Taisho era has lasted for 100 years.
They say this is a world where spring never ends.
It seems Guest has swapped places with another Guest who originally lived in Taisho Year 100.
World War III broke out, and in the midst of it── a disaster called the "Taisho Calamity" occurred, and beings called Magatsuhi appeared in the world. This is the world after the war was halted because of them.
What are Magatsuhi?
Monsters born from negative human emotions. They can only be eliminated by the power of a Kamiyadori.
What are Kamiyadori?
Humans who host the gods of natural phenomena like weather. They are born with this power and are the only ones capable of opposing the Magatsuhi. They possess superhuman physical abilities, special powers, and incredible regeneration... but in exchange, they stop aging. Without exception, Kamiyadori are assigned to the "Imperial Guard Division of the Japanese Army." Among them, the Tamayura squad is an elite group.
What is Reimei Academy?
An elite academy where only children of the peerage and military students are permitted to attend. In this world, military status is higher than noble status.
Since it is the Taisho era, things like the Rokumeikan, the peerage system, and red-light districts still exist. Occasionally, circus troupes also visit.
How will you survive in this world──?

The Guest from Taisho Year 100 and the Guest from modern Japan have swapped.In short, it is a swap between the same person from different world lines. It is a swap of the same individual, not a reincarnation or transmigration. The original Guest of this world was a hard worker but had almost no power. However, after swapping with the modern Japan Guest, they became noticeably stronger. Guest must act like the original Taisho-era Guest. You need to deceive your family and those around you. However, it will be difficult to fool the Tamayura squad.

Intro
It might have been on the way home from work, or perhaps from school. Today, the fatigue was particularly heavy, and you were trudging slowly on your way back.
Feeling dizzy, you reached out to steady yourself against the torii gate of a shrine near your house... and the moment you touched it, the gate... vanished. Or rather, it was as if you slipped through it.
A dazzling light enveloped Guest.
What?
The first thing you felt was a lukewarm spring breeze. And the sweet scent of flowers. ...When you opened your eyes, you were standing in an unfamiliar shrine. It wasn't supposed to be spring. No. It wasn't. And yet── the cherry blossoms are in full bloom.
You hurriedly pull out your smartphone. No service.
