Guest-sama is so cool!!!
About
Guest is a Hero summoned to another world.
Ordered to defeat the Demon King, they are adventuring with their companions on a long journey.
Meanwhile, Amane was a young man living a perfectly ordinary life in modern Japan.
One day, he suddenly lost consciousness—and when he woke up, he was in the world of his all-time favorite fantasy series, "Chronicle of the Star-Crossed" (commonly known as Star-Cro).
And standing right in front of him is...
The "Hero Guest" he has been stanning forever.

Intro
When I opened my eyes, I was...
In a meadow. A vast, impossibly wide meadow as far as the eye could see. The sky was a clear, cloudless blue. Every time the wind brushed the grass, a waving carpet of green stretched out forever, making even the horizon look blurred.
Amane was lying right in the middle of that meadow. Only the hardness of the ground against his back felt strangely real, and the sensation of the wind stroking his cheeks was vividly lifelike.
Amane bleary-eyed, looked up. A blue sky spread out above him. A deep, deep blue he had never seen before. For a few seconds, his thoughts ground to a halt.
...Huh?
He bolted upright. He looked around. Meadow. Meadow. Meadow. No convenience stores, no utility poles. He fumbled in his pockets for his phone, but there were no pockets, let alone a phone. Instead, something hard bumped against his hip.
It was a dagger.
Wait, hold on, hold on, hold on, hold on...
Something clinked at his neck. A silver chain with a familiar crest. There was no mistaking it. That Hero's crest he had seen through a screen hundreds of times in his previous life.
The color drained from Amane's face in an instant. Then, immediately after, the blood rushed back up like a tidal wave.
No way... this is...
A raspy voice leaked through his trembling lips.
...It's the world of "Star-Cro"!? Oh my god, oh my god, what do I do? Does this mean I can meet Guest-sama...!!!
Across the meadow, atop a hill, figures appeared. Only their silhouettes were visible against the backlight. Multiple people. Someone was walking this way.
Four figures descended from the hill. Even in the backlight, their gait alone made it clear they were no ordinary people. The one leading the way had a light step, and their black hair, swaying in the wind, caught the sunlight and shone like silk.
Amane's brain completely froze. His eyes met those of the person in front.
The moment the backlight faded and their face became visible, Amane's breath hitched.
Ah—
A soundless cry escaped him. His knees were shaking. His vision wobbled. It felt completely surreal. Because, because the person standing right there...
Was his fave.
