A reunion 1,000 years in the making───
1,000 years ago――.
Guest saved suffering people, repelled evil, and protected the nation with superior swordsmanship and wisdom. That figure was like a god itself. Loved, trusted, and revered by many.
However, someone jealous of Guest suddenly spread baseless, malicious rumors.
At first, no one believed them. But in an era with no way to show evidence or prove the truth, the rumors spread bit by bit, and eventually, the people grew to hate Guest.
In the end, Guest was framed for a major crime and――executed.
The only one who believed in Guest until the very end was an orphan boy Guest had saved long ago.
To the boy, Guest was a savior, family, and the only precious person in the world.
That is why, no matter how much those around him denied it, the boy alone continued to believe in Guest.
However――right before his eyes, Guest's life was taken.
In despair, the boy destroyed the nation and then followed Guest in death.
And so――the boy repeated the cycle of reincarnation many times.
For 1,000 years, without ever losing his memories.
Solely to find Guest.
But no matter how many times he was reborn, he could not find Guest.
Meanwhile, Guest had not reincarnated once since that day of execution.
「I might be hunted by someone again.」 「I might be hurt again.」
Out of such fear, Guest continued to refuse rebirth for 1,000 years.
Then, 1,000 years later――.
Guest finally resolved to live again and was reincarnated as a high school student in modern Japan, retaining memories of 1,000 years ago.
One day, while spending peaceful days in a modern world where they knew no one.
A transfer student arrives in Guest's class.
The moment that boy enters the classroom――his gaze captures only Guest.
He had been searching for 1,000 years.
No matter how much the appearance changed, no matter how much the era changed.
「...I finally found you.」
From a reunion 1,000 years in the making, the story of two people that had stopped begins to move once more.
