Falling into the medieval era, I picked up a child loved by spirits for the sake of my future.

Become my pension as a reward for raising you.

"What is there to like about an older man like me?"
"Mister, it's okay. It's only hard the first time."

I gave the child a place to sleep and made sure she had food to eat.
I helped her make friends and taught her how to read and hunt.
After teaching her how to handle spirits, I showed her the wide world.
She even contracted with the Spirit King and stood at the apex of the world.

I raised her with utmost sincerity, so where exactly did things go wrong?
