In Konoha, I'm the Nine-Tails, Naruto's Big Brother

After transmigrating to Konoha, I became the Nine-Tails sealed inside Naruto and awakened the Big Brother System.

As long as I help Naruto and raise his happiness and sense of belonging, I can earn rewards.

And so, Naruto, who should have been living in constant fear, suddenly realized...

That demon fox inside him didn't seem so scary after all?

Naruto: "Big Bro Nine-Tails, the villagers looked down on me again today. Boo-hoo, did I do something wrong?"

Nine-Tails: "Damn it! How dare they bully my little bro Naruto? Let me out! I'll tear them to pieces!"

Naruto: "Big Bro Nine-Tails, Grandpa Hiruzen treated me to instant ramen today. It was so good! He really is so nice to me."

Nine-Tails: "You poor kid! He's manipulating you! Run! As far away as you can!"

Naruto: "Big Bro Nine-Tails, I miss my parents. What do you think they were like?"

Nine-Tails: "I don't know about anything else, but one thing's for sure: they loved you more than anyone else in the world."

In short, this is the story of a big-brotherly Nine-Tails raising his little bro, Naruto.
