Reborn as Gojo's Useless Little Sister

My name is Gojo... Satou.

I woke up one morning with a new big brother and a game forum in my head.

The forum told me that my brother is the strongest in the whole world, while I am his polar opposite, "the weakest."

There's a huge gap between the siblings, but so what?

After all, my brother is doting on his useless imouto again today _(:з"∠)_

An anonymous diary (Part 1):

[My little sister is a monster. When she was born, she was nothing but a bloody mess. The frightened midwife was about to strangle her, driven by terror, but the next second she was smashed into an exploding mass of bloody chunks by invisible "hands" surrounding my sister...]

[I'm going to have a little sister?]

An anonymous forum:

[1L: Hey, everyone, listen up! I found a really interesting raising-a-kid game! Here's what happened: at the very start, my internet lagged, and then somehow an NPC inside the game tried to attack my newborn baby. I reacted instinctively and clicked, and that NPC went "pop" and burst into a spray of blood [picture] [picture]]

[2L: Damn, that's a new definition of "interesting." But the art style looks pretty cute. Anyone got a link?]

[3L: I'm in love with the white-haired little sister. I'm waiting for the link too.]

[4L: +1]

[5L: +10086]

[30L: I'm here, I'm here! OP here, xxxxxxx <- link's right here. But the game is still in beta, and for now, multiple players can only raise one character together.]

[31L: Huh? The save file is shared? Never seen that before.]

[32L: I checked the description. Sounds interesting, so I'll download it and give it a try.]

[33L: Wow, suddenly there are so many people! Let's talk about how the game is going in this thread from now on, ov-★]

[560L: Damn it, that rotten orange is planning to give our Satou baby away. I'm gonna pew his brains out!]

[561L: The maid, Ahua, told me they're planning to send her to a family with a super arrogant white-haired brat. If our Satou baby becomes his little sister, he'll definitely bully her to death. I'll take him out as soon as I see him.]

[562L: I agree. I still prefer the little angel Zenitsu as her big brother!]

After post n+1

[3008L: Holy crap, girls, I've changed my mind. Go-chan is so cute! Who would have thought he was secretly a tsundere siscon?]

[3009L: When I logged in today, I secretly wrote "I love you, big bro" on the crib with a watercolor pencil. When Go-chan comes to see his little sister tonight, he'll definitely think she wrote it!]

[3010L: Www, I can't wait for the next update! Little Go is definitely going to be secretly thrilled when he sees it! After all, he had dark circles under his eyes the day after Satou first called him "Big Brother." ]

[3011L: Girls, take it easy and be careful. We absolutely can't let Little Go find out about Satou's "ability," meaning the things we players do, or he might call her a monster again.]

[3012L: Got it, got it. We just have to stay useless (crossed out) and cute in front of our powerful onii-chan, w]

My Wife Satou, forced to have the power of a Stand user (crossed out) a monster because of the forum players: ?

Hey, she can't take the blame for this...
