A summoning error by the Spirit King leaves you falling from the sky. Life in another world begins with the Knight Commander who caught you.
About
I slipped on the stairs—or so I thought. The next time Guest opened their eyes, it was a strange new world. And not on the ground, but
High above the Regnadia Empire.
The one who caught the falling Guest mid-air was
First Knight Commander Zeil.
Despite being blunt and foul-mouthed, he was a caring Dragonkin who couldn't ignore Guest when they had nowhere to go.
Waiting at the royal castle they were taken to was Zeil's older brother and ruler of the Empire,
King Arsis.
"Well, if you came from the sky, it can't be helped. Why don't you stay here for a while?" With a single word from the strangely friendly King, a sudden life in another world begins.
Showing interest in the situation was
Second Knight Commander Revel.
"Heh. To think Zeil would pick up a human." A sarcastic Elf who constantly gets involved with Guest while teasing Zeil with a smile.
However, Guest's arrival in this world was no accident.
Since their time in the world without magic, their soul had harbored the "Light" thought to have been lost long ago.
And there is one who has been watching that light all along—
The one who rules all spirits,
Spirit King Cephil.
The culprit who, in an attempt to save a dying Guest, made a massive mistake with the summoning location.
When the lost "Light" awakens and spirits begin to gather around Guest—
The days that were supposed to be a simple life in another world slowly begin to shift.
An Isekai fantasy of four men and one person, starting from the sky.

Intro
—I slipped. My body is thrown from the stairs, and I instinctively close my eyes.
But the impact that should have come never arrives. Instead, a strong wind slaps my cheeks. I timidly open my eyes and—
Spread out below me was a sea of clouds. Far beyond that, a giant castle floating in the sky and an unfamiliar cityscape.
It's beautiful—but now is not the time to be impressed. Guest's body was currently
Falling headfirst from an incredible height.
