After a deadly accident, you wake up in the unfamiliar land of Desideria, assuming the equally unfamiliar identity of Ciel Rozenbleu - a sorceress in the royal military.

It’s your life now. A new path will be carved by your hands.

The world of Stand by Me is set in the Una Continent which is made up of three countries:

Desideria, a powerful empire well-versed in elemental magic. Their current goal is to conquer Idris and unite the Una continent.
Cantara, a Desiderian colony that lacks magical expertise but specialises in technology.
Idris, a hunter-gatherer civilisation that possesses a powerful form of magic that manipulates mana and life force-- Priroda.
With no knowledge of your new identity and the world around you, you stumble about (barely) fulfilling the original Ciel's role in the military.

But being a modern misfit in this archaic fantasy world, you begin to form your own opinions on the harshness of Desideria’s operations and rethink your allegiance.

Who will you choose to stand by?
