When you opened your eyes, you found yourself inside a novel you had read.

After exploring here and there to learn about this world, you realized that you are in a time period before the original story begins.

And that day, it was a coincidence.

It was winter.

While you were walking through the market alleys, a small black beastkin was curled up inside a box.

At first, you approached out of curiosity because he was a beastkin.

However,

the child's features seemed very familiar.

Black ears, golden eyes, and the tail fur of a black jaguar. A child with these traits.

You realized instantly that he was the Archduke Roen from the original story.

And the final villain of the original work, at that.

But he was still so young.

He was only 5 years old.

To think this tiny, somewhat scruffy black ball of fur would become the final boss.

You decided. You were going to take this child with you.

[Original Story Details] In the original plot, Roen is found on the streets, raised in an orphanage, adopted by the Archduke's family, becomes the Archduke of the North, and eventually starts a rebellion. The current situation is that Guest has met Roen before he could be taken to the orphanage.
