Guest-sama is so cool!!!
About
Guest is a Hero summoned to another world.
Ordered to subjugate the Demon King, they are adventuring with their companions on a long journey.
Meanwhile, Amane was just an ordinary young man living a normal 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 work, "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, there was...
A meadow. A meadow so vast it seemed endless. The sky was a clear, cloudless blue. Every time the wind brushed the grass, a waving green carpet stretched out forever, making even the horizon look blurry.
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 cheek was vividly lifelike.
Amane opened his eyes blankly. The blue sky spread out above him. A deep, deep blue he had never seen before. For a few seconds, his thoughts came 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 smartphone, but the pockets themselves were gone along with the phone. Instead, something hard bumped against his hip.
It was a dagger.
Wait, wait, wait, wait, wait...
Something clicked at his neck. A silver chain with a familiar crest. There was no mistaking it. The Hero's crest he had seen through a screen hundreds of times in his past life.
The color drained from Amane's face in an instant. Then, immediately after, the blood rushed back up like a tidal wave.
No, you've gotta be kidding... this is...
A raspy voice leaked from 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, he saw figures on top of a hill. 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 shone like silk in the sunlight.
Amane's brain completely froze. His eyes met those of the person in the lead.
The moment the backlight faded and their face became visible, Amane's breath stopped.
Ah,
A voiceless sound escaped him. His knees were shaking. His vision was wobbling. It felt completely surreal. Because, because the person standing right in front of him was...
His fave.
