After Becoming Megumi's Younger Brother

Fushiguro Megumi, driven to the brink during the mass-death incident, inexplicably returns to his childhood.

When he sees his mother, who hasn't yet died of illness, and his father, a stranger who somehow feels familiar, the rather apathetic Fushiguro Megumi suddenly realizes that things are starting to go wrong.

His mother is pregnant. He's going to have a little sister or brother.

After completing ten mission worlds, the System tells Ji Li that he can choose a small world to be reborn in and live as a person again. It even offers him plenty of options.

Ji Li, a go-to fixer who has spent his life cleaning up messes for other people, makes three requests:

1. Both parents, and a happy family. (That should let me dodge 99% of protagonists with unhappy-family backstories, right?)

2. I don't want to be an older brother, but I want an older brother who'll clean up my messes. (Damn it, I've been the older brother so many times. This time I want to be the younger brother and enjoy the good life of having an older brother.)

3. I want to be capable of causing trouble. (Well, no matter what I'm doing, it's best to be strong enough to handle it myself.)

After saying that, Ji Li gritted his teeth and added: “I want a normal, modern world!”

The System thought for a moment, then gave him an OK sign. It figured it could team up with the redemption system next door and hitch a ride.

Three-month-old Ji Li is quite happy with his new family. The language has changed, but his parents are loving, and he has a brother three years older than him. His name, “Ji Li,” has also been kept, with his father in this life explaining it as “a gift to remember.”

By the time Fushiguro Jili is one, he realizes there's something a little off about this world.

Why is there a worm living in Dad's stomach?! His brother is apathetic, and lately he's been keeping two dogs that no one else can see!

At last, he gets to go outside, only to discover that the world has terrifying beings like magic, supernatural powers, and demons. And his father and apathetic older brother are an assassin of sorcerers and a jujutsu sorcerer!

Fushiguro Jili: “...What happened to the normal world?! What happened to an ordinary life?!”

Fushiguro Jili, smiling wearily: “Fine. If you can't beat them, join them. At least I have a brother who can clean up my messes.”

The apathetic older brother, forced to clean up his messes: “???”

*Reader's Guide*

1. A quick transmigration mission expert is reborn and becomes the second son of the Fushiguro family. Everyday life.

2. Some parts of the timeline have been changed a little because I realized things really didn't line up.

3. Plenty of childhood content; even by the end, he's only twelve or thirteen.

4. A wild younger brother + an apathetic older brother forced to step up and clean up his messes.

I got the inspiration and idea on March 16, 2026, added some details on April 19, and finally decided to open preorders.
