I am Uzumaki Hotaru, the daughter of Uzumaki Naruto and Uchiha Sasuke.
After transmigrating, I realized parallel worlds existed. After witnessing my fathers' worst possible futures with my own eyes, I decided to follow the branches and change the endings of different worlds, nipping every factor that could keep them apart in the bud.
[Nine-Tails' Attack]
Minato and Fugaku: Wait, is this girl with the Sharingan and Rinnegan really my future granddaughter?
Kushina and Mikoto: She's so cute!
[Both Defect]
In the bitter wind, two groups faced off in silence. The wind whipped the Akatsuki cloaks as they fluttered. Just as Team Seven, once united, fell apart and battle became inevitable, a girl appeared out of nowhere and broke the deadlock.
Naruto: My daughter with Sasuke? For real?
Sasuke said nothing, only frowning.
Hotaru looked at Tobi with a serious expression. "Excuse me, is the Akatsuki recruiting?"
Tobi: "No..."
Hotaru: "I have the Rinnegan."
Tobi: "You're in."
Zetsu: I have a bad feeling about this.
[The Last]
Hotaru didn't expect the first thing she'd do after meeting Naruto to be fight him. She'd planned to resolve this world quickly, but some people insisted on asking for trouble. She blew up Konoha on the way and stomped on it a few times, successfully making everyone tremble in fear.
Hotaru: Honestly, I've wanted to do this for ages.
Naruto had just returned from confessing at the ruins. Looking at the crater hundreds of meters across: "? Is Senior back?"
Hotaru: "Nope. Just a friendly hello."
Toneri: "Six."
The advisors, lying stiff as corpses: "..."
[Fourth Shinobi World War Battlefield]
The world is full of wonders, but this is a first.
Neji started to say something, stopped, started again, and finally decided to keep quiet.
Naruto, screaming: "No, what the hell?!"
Sasuke: "Why is her surname Uzumaki?"
Obito: "Wait, I didn't cast the Infinite Tsukuyomi either."
Hotaru calmly accepted everyone's astonished stares and used a secret technique to tell them the whole truth. After becoming the Ten-Tails' jinchuriki, her ocular powers advanced by leaps and bounds, allowing her to glimpse the threads dangling above everyone's heads, like the strings in a puppeteer's hands.
Hotaru promptly sent all her memories through the threads. There were too many worlds for her to visit every one, so since they were branches, she might as well send them a little something.
No breaking up Naruto and Sasuke, no reversing their roles.
