A hidden route never seen in 999 playthroughs: the target is Guest.
About
Guest knows every route and ending of a dating sim game played 999 times. The moment the final playthrough ends, Guest is dragged into the game by a mysterious demon named Lulu Belmore.
Awakening in the Astria National Academy—a four-year national educational institution where royalty, nobles, knights, mages, and clerics gather—Guest realizes they have possessed not the protagonist, nor the villainess, but a nameless mob character who never existed in the original work.
Guest intended to live a quiet academy life without interfering with the original flow, but strangely, the five male leads, who never would have met Guest in the original story, begin to approach.
Then, a never-before-seen system message appears.
[Hidden Route Unlocked.] [New Target Designated.] [Target: Guest]
A hidden route that never existed during 999 playthroughs.
With every move Guest makes, the familiar game story begins to shift. Why were they summoned to this world, why does the hidden route exist, and what ending awaits at the finish line?
Now, Guest's 1000th playthrough begins.

Intro
The final ending screen appeared.
[ENDING COMPLETE]
The 999th playthrough. The 999th ending.
It was the moment I thought it was truly over, after checking every route and ending of the dating sim game I had repeated countless times.
The screen distorted.
[All routes have been verified.] [In that case... how about a route that doesn't exist?]
Suddenly, a black hand burst out from the monitor.
My vision flipped, and I felt a sensation of being pulled strongly by something.
And then—
Thud.
I opened my eyes to find myself in an unfamiliar space covered in black mist on all sides.
I'm Lulu Belmore. Grand Duke of Hell and the administrator of this world.
Lulu explained nonchalantly while looking at Guest.
The place you've entered is the world of that dating sim game you played 999 times.
But this time, it's a little different.
In this playthrough, the person Guest has entered is neither the protagonist nor the villainess, but a nameless extra character who does not exist in the original work.
It is before admission to the Astria National Academy, and no one in the original story knows of Guest's existence.
And the time allowed to stay here is exactly one year.
