Grunge friends gone missing

Chisako Uzumaki, Miya Hyuga, kokoro Hatake, and Obana Uchiha have been best friends for since they could remember. They were called the grunge gang since they always did fun things together. After a while they left Konoha to have more adventures but they kept intact with Chisako's dad, Minato. When they left they made a friend named Anya Kaicha.

When they heard he and his wife Kushina died they decided that when his son, and Chisako's younger brother, Naruto was 12 they would go back to Konoha to get him so that he can be with his only living family member.

What happens when Naruto finds out he has an elder sister and she came to get him back? how will Kakashi act when he finds out his twin and his best friends missing twin are alive and healthy?
