My Best Friend's Child Is Three Before He Turns Evil

[Blurb] Dads, go ahead and fall in love. Leave saving the world to the kid! (The companion series is complete: Five and Geto's kid, but the dads never dated.)

*‖A youthful romance about the DKs falling in love after having a kid (a slapstick comedy full of chaos):

His best friend said he was suffering through a miserable summer. Gojo didn't think much of it, but quietly kept an eye on him.

Geto had gotten a little thinner.

Geto had such dark circles under his eyes. Was he having trouble sleeping?

Geto had moisture on his lips. Had he thrown up?

Geto's cursed energy was acting weird, all lively and bouncing around.

Geto smelled milky. So good!

Why did the child in Geto's bedroom look so much like Geto?

In a flash, Gojo understood everything

His best friend Geto wasn't suffering through a miserable summer. He was having a baby!

Gojo was stunned!

Seeing that the child still had some of his own cursed energy, Gojo: !!!

Geto had been hiding that he was an omega, but he was still willing to have their baby?

Geto loves me so much!

The world's best best friend, Gojo, swore: I'll never let Geto down! We'll get married, right now!

*

Looking at Gojo, who had suddenly shown up with a baby in his arms to announce his engagement, homeroom teacher Yaga slowly typed a question mark.

Who had a child with whom? Who was marrying whom?

Gojo announced smugly: That's right, Geto and I have a kid!

A female classmate walking by nearly dropped her cigarette and promptly fled.

Nanami and Haibara watched their upperclasswoman leave. What did Gojo just say?

Gojo spotted his underclassmen, his eyes lighting up as he ran over. Little Satoru, look! These are Dad's juniors!

The child, with double pupils in his right eye, gave them a look and said in a hollow voice: They all die horribly. This school is doomed.

His juniors: !!!

Hidden in a corner, Geto watched helplessly as his best friend spread rumors. ...There's no explaining this. I might as well defect.

*‖A genius three-and-a-half-year-old kid who saves the world:

Geto Satoru was born already three years old. He had eyes that could see the future and was a genius child in every sense of the word. What's more, he had two special-grade dads, so he could do whatever he wanted in the jujutsu world!

But B-king Geto Satoru had a little secret of his own. He seemed to be bound to a world-saving System.

On day one, he took his bangs-dad to Yokohama to stop the rampaging Arahabaki;

On day two, he took his sunglasses-dad to Yokohama to save a boss who'd fallen from a building;

On day three, he took his big brother and big sister to Yokohama to punish the bad guys who kidnapped children;

Huh? Why is it always Yokohama? What happened to saving the world?

After beating up the System, he finally went somewhere other than Yokohama this time!

Geto Satoru happily held his bangs-dad's hand with his left hand and his sunglasses-dad's with his right, then plopped down in a crowded subway station

Huh? Why is that guy who looks just like bangs-dad, but has stitches on his forehead, smiling so creepily?

Huh! Why does that white-haired guy, who's kneeling on the floor and trapped, look just like sunglasses-dad?

While Geto Satoru was trying to wrap his head around it, his two dads charged in with a bang, and a pink brain bounced out of a skull flying through the air!

Three-year-old world-saver Geto Satoru: Huh?

A companion story to the Five and Geto's kid story next door. Satoru is a miracle born from the fusion of cursed energy, not through childbirth.

A story about Satoru being born before Geto defects, but with him hopping between parallel worlds in a crossover.

Also known as: The World-Saver Is Three and a Half, The Strongest DKs' Guide to Raising a Kid, My Best Friend Keeps Saying He'll Divorce Me After Our Child Is Born, and more (just kidding).

The three father-and-son characters should all have significant roles. The dads are in a youthful romance, while the kid gets a story about a toddler saving the world. One set, multiple shows.

Theme: Laugh and embrace one another during adventures
