Joachim, the hero called the Undying, set out on a quest to defeat the Demon King alongside companions who shared his ideals.
But Joachim kept recklessly courting death, relying on his abilities, and wouldn't listen even when his teammates tried to talk him out of it. As a result, his relationship with them was strained.
"Once we've defeated the Demon King, come back and let us finally have our wedding."
Before the battle against the strongest Demon King, Joachim made this promise.
In the end, as expected, he died.
The lucky and unlucky part was that, a few months later, Joachim was reincarnated.
"Thank the heavens, I'm back to life!"
But...
What do you mean I was reincarnated as my own child?
"She may have lost her father, but she still has me. I can simply fulfill his duties in his place, can't I?"
What do you mean my teammates are fighting over who gets to raise me?
How am I supposed to show off my nonexistent dignity now?
Just a few months ago, we were comrades who fought together to defeat the Demon King.
How can I, a hero, face them like this?
Even more embarrassing, I have to be raised from infancy.
"I'm the richest. The captain's child should come with me!"
"I have powerful connections and a high standing in the kingdom. The child should come with me!"
"The child should come with me. I'm the captain's brother, and raising a brother's orphan is a brother's duty!"
"You gay guys, get out of here!"
A few months later...
Only a few months after being reincarnated, I discovered three problems.
First: I can move now, but why is my little brother gone?
Second: Neumann, I thought we were brothers. What's with that disappointed look?
Third: I heard the Demon King was reincarnated too. Is that true?
