The Retired Life of a Laid-Back Savior Raising Kids

[The entire outline has been rewritten. I'm sorry to those who read the previous version.]

Jiu Chuan Yueyong, a savior who traveled through countless worlds, was his boss's favorite employee, working around the clock.

After completing yet another mission, Jiu Chuan Yueyong, who felt restless whenever he wasn't working, frantically prodded the System to give him a new assignment.

The Main System had no missions to give him, so it promptly dumped him into a crossover world and assigned him a new task:

[Raise the world's main characters and help them grow into reliable adults.]

Jiu Chuan Yueyong, who had no experience at all and only knew how to fight: ...I don't know how to raise kids!

Having only ever raised magical beasts, Jiu Chuan Yueyong had no choice but to grit his teeth and give it a try!

When faced with a little bandage-wearing kid who wanted to embrace death, Jiu Chuan Yueyong pondered. It wasn't a difficult request, so he could grant it. He promptly tossed the kid into Hell to experience death.

The kid, put through his paces by a Hell's Envoy wielding a spiked club, came back in tears, begging to return.

Seeing the green-eyed kitty throwing a tantrum on his lap and refusing to go to the dentist, Jiu Chuan Yueyong pondered again. Without hesitation, he knocked him out and packed him off to the hospital.

He even gave him an idiot buff so he could experience the life of an ordinary person.

Faced with an experimental subject who had great power but was utterly naive, Jiu Chuan Yueyong pondered yet again.

Maybe... he should teach him how to raise his hand and squat?

After the System gave him a lecture, he calmly picked up an early-learning book and said, "You eat with utensils. Now repeat after me."

Seeing the divine child in a kimono staring coldly at him, Jiu Chuan Yueyong pondered once more.

Usually, taming a rebellious magical beast just took a beating. Maybe the same went for kids.

Jiu Chuan Yueyong drew his weapon and swung it with a blank expression.

Before Jiu Chuan Yueyong even realized it, a whole group of kids had gathered around him.

He looked at them, feeling a desire in his heart to stay with them forever.

It wasn't affection for pets. It was... family.

An unknown transcendent arrived in Yokohama, with a group of extraordinary children gathered around him.

Despite his immense power, he was content to stay in his little flower shop.

When someone tried to test him by going after those children, the guardian, who had always been emotionally detached and never involved himself in major affairs, split the sea of Yokohama with a single slash of his sword.
