Those Two White-Haired Guys Who Never Act Out of Character Are Actually Brothers

The sky was clear and cloudless. October's weather was still a little muggy, but everything felt so pleasant... "Huh?!! Shinpachi! Kagura! Weren't we supposed to go back to the Odd Jobs together? Why'd you leave Gin-san all alone here? And where is this place, anyway? Why has Gin-san turned into a baby who needs his mama to keep soothing him, or he'll start bawling so loudly the neighbors will complain?!!" A little baby with a mop of unruly silver-white curls and dead-fish eyes, who called himself Gin-san, waved his arms and wailed silently with his toothless mouth. Well... it doesn't seem all that pleasant after all. Basically, this is about how, at the end of the movie "Gintama: The Final Chapter - Be Forever Yorozuya," everyone returned to their own worlds, but Gin-san got sent to the world of Jujutsu Kaisen because of a space-time mishap. On top of that, he became the newborn little brother of the Gojo Clan's Satoru Gojo. A few notes on the setting: 1. Gin-san's birth wasn't welcomed, probably because certain rotten adults were jealous. After all, he had a big brother who's at the top of the power scale. 2. In this life, Gin-san's parents didn't raise him themselves. They handed him over to servants, who raised him outside the Gojo Clan, so few people know the identity of the Gojo Clan's young master, Gin-san. The public story is that the young master was frail and died young. 3. Since the author hasn't read the Jujutsu Kaisen manga, the plot will mostly follow the anime. With Gin-san joining in, the story is bound to go off track. This isn't a serious story, so just treat it as a lighthearted, ridiculous comedy (...). That's all. The main story is updating now. There are no chapters in reserve, and updates will be slow. I started this story purely to indulge my shipping-nerd spirit and pair these characters up. The most important thing in life is to be happy~ Theme: Sakata Gintoki and Satoru Gojo's crack pairing, here we go! (They're technically brothers, though!)
