Uzushiogakure no Orenji Arashi
Raised in Uzushio
A month after Minato and Kushina sealed the Kyuubi into Naruto, Kushina's father arrived in Konoha to take Naruto into his care. He bargained with Hiruzen and was able to garner a deal with him. That he could raise and train Naruto during his early years, but he'd have to return to Konoha when he was twelve to become a full-fledged genin. In exchange for this, he must 'trade' Konoha will a few new moderately high-level seals to enhance or replace certain ones already in use. It was a hard trade, but it was ultimately accepted on both sides.
Naruto spends the next twelve years living and training with the remains of the Uzumaki clan who live in a small town on the peninsula of southern Hi no Kuni. They can't form an official ninja village, but they do establish a ninja guild (based on Fairy Tail) to act as a local academy and ninja business office for the villages too far south for Konoha to reach regularly.
On the night after the Genin Exam, Mizuki breaks into the Hokage Tower and steals the Forbidden Scroll. Naruto (who had gotten lost and late for the exam, frantically racing to Konoha) literally runs into him. Mizuki attacks, hoping to kill the brat before he can raise the alarm. But Naruto is able to fend him off and knock him out with the Oiroke. After foraging his belongings, Naruto finds the stolen scroll and an incriminating letter from Orochimaru, telling Mizuki to prove his loyalty by acquiring something of immense value and importance (Forbidden Scroll). Naruto drags Mizuki and the Scroll back to Konoha, sneaking in through the barrier surrounding Konoha just for fun.
The next day, Naruto bumps into Hinata on the street, who is quickly smitten with his strong and boundless outgoing personality, overwhelming impulsive happiness, and his incredible skill of spreading hope to others. He discovers Ichiraku and instantly proclaims it to be his all-time favorite restaurant ever. Summoned to the Academy, Naruto has to get his picture taken for his ninja license. As he's leaving, he meets Sasuke and notices his adoring fan club tailing him. Seeing Sasuke's hidden annoyance at their presence, Naruto decides to help him by casting a seal on Sasuke that makes the fangirls unable to see Sasuke for five minutes (temporary invisibility). Sasuke uses the chance to escape while committing the seal sequence to memory and growing very curious about the new kid.
*Naruto knows the Kage Bunshin, numerous C- and B-class seals, mixed taijutsu, several Fuuton (including the Kazeken, based off Natsu's nintaijutsu), and considerable knowledge of the world social climate due to his many frequent travels with his clan and cousins while on missions.
*He already has a long list of completed missions: 0 D-class, 44 C-class, 20 B-class, and 3 A-class.
*Natsu, Kimiko (Erza), Hikari (Lucy), Yuki (Gray), Akemi (Mirajane), Sora (Wendy), and Amaya (Juvia) are his closest friends.
*Naruto aspires to become as great as his father, stronger than his mother, and even more awesome than Raiden (Laxus).
