Domain Expansion: Everyone Gets Dumber!

Your name is Nobody, and you're an ordinary gamer. One day, you open your eyes and discover that you've transmigrated into a fan game based on a popular IP. And your role is still Nobody. As everyone knows, the original is a classic action-packed shonen manga. Curses are everywhere, and ordinary people are all cannon fodder. To avoid the awkward fate of dying from the start, you steel yourself, grit your teeth, and make a ten-pull with paid currency. Luckily, you draw an SSS-rank skill, the pinnacle of cursed energy: Domain Expansion. But... you read the description of your domain and fall into deep thought. [Domain Expansion: Collective Dumbing-Down. Once the domain is activated, every living being drawn inside will become less intelligent of their own accord. Only the domain's caster and any living being you touch are unaffected.] You: ? All right, all right. This is exactly the kind of deranged game you like. - It was the summer of 2005. The young Six Eyes and his best friend encountered something strange while on a mission. The person before them, who had no cursed technique and barely any cursed energy, unexpectedly awakened an ability neither of them had mastered yet, at the brink of death, and successfully dragged the two of them, along with the curse they were supposed to exorcise, into a domain. The moment they entered the other person's domain, his mind was instantly filled with sweets and snacks, while his usually mature and composed best friend started singing nursery rhymes on the spot. “...” This was so embarrassing. If he could help it, he really didn't want to be classmates with this weirdo who'd made them lose face! – [Bonus Scene 1] After entering Jujutsu High, the Six Eyes' prodigy, unwilling to admit defeat, came looking for you and challenged you to a “friendly” match between classmates. You activated your domain and clearly saw the white-haired classmate stand there, dazed and unresponsive, for several seconds. Your other two classmates each held a small notebook and watched the fight with serious expressions. Three minutes later. The Six Eyes tripped when he tried to attack the spot where you were about to land. Outside the match, his best friend quickly wrote down: “One: reduced athletic ability.” Five minutes later. The cursed energy the Six Eyes gathered shot wide of its mark. Beside him, the black-haired girl wrote: “Two: difficulty with precise motor skills.” Ten minutes later. Unable to catch you, the Six Eyes stood in the middle of the field and yelled angrily, “Hey, how long are you going to keep running? Get out here, you stinking doll!” You silently looked down at the Lolita outfit you'd bought with paid currency: “...” On the steps, the black-haired girl with a cigarette between her lips exchanged a look with the young curse user. They lowered their heads and wrote in their respective notebooks: “Three: language skills have regressed.” “Four: emotions are difficult to control, with irritability and aggression.” In conclusion Under the influence of your domain, the prodigious classmate who had changed the jujutsu world from the moment he was born was currently about three years old. Shoko sighed calmly: “Bury him. He's beyond saving.” [Bonus Scene 2] After a great deal of hard work, you successfully reached No. 1 on the list of “Jujutsu Sorcerers You Least Want to Encounter,” outranking even the Six Eyes of the Gojo clan. One day, your classmate, the curse user, came to confide in you. The main quest indicated that he was on the brink of crossing the line, and you needed to step in and save him. You: ? You: Save him from what? Being a curse user sounds pretty good, doesn't it? Geto: ? That's not how I imagined this going. You draw on the knowledge of junior high history you learned years ago, and tell him righteously: What's the point of constantly brooding over all that stuff? Why not do something practical instead? Let's start an internal revolution and change the jujutsu world! Geto: ?? You: Have you ever heard the saying, “The enemy of my enemy is my best friend”? Geto: ??? With a grand sweep of your hand, you issue your orders boldly: From now on, I'll handle things at home, and you handle things outside. I'll clean up the old maggots occupying their seats in the jujutsu world without doing their jobs, and you gather outside forces and organize them for my use! The Time Vessel Association seems pretty good, for example. Let's start by taking it down! Geto: ...Wait a minute, I don't think I agreed to this. I never said I wanted to be a curse user! You launch into an impassioned speech: That's not important! What's important is whether you care about the young flowers of the jujutsu world! Look at those underclassmen over there. So innocent, so wonderful, with such bright futures ahead of them Geto: ... All right, all right, stop talking. He'll do it, okay? He'll do it! *Pairing: 5t5. A powerful partnership, sweet romance + my own brand of feel-good wish fulfillment. There are some elements of the fourth calamity, but they're not the focus. The story is mainly light and slice-of-life. *Not friendly to fans of Sukuna or Kenjaku. *An online refuge built by Gojo fans. Posts involving numerical jokes (and other tired memes), offensive dark humor, and emotional comments targeting anything already covered in the warnings will be deleted. Thanks for cooperating. Warnings: This is not a fourth calamity story. Only the early parts include some fourth calamity behavior, so don't read it for that reason x (Repeating this for the third time.)
