The Uzumaki and Kurogane Clan

What would happen if the Uzumaki Clan had a shadow clan that protects them in the dark yet where still destroy alongside the Uzumakis? well just like Kushina who survives the massacre, 2 survivors of the Kurogane Clan join the leaf and on the same day that Naruto was born their son is born as well, receiving the Yin half of the kyubi. Come and watch the story of Kira Kurogane, how he leaves the leaf due to the hate and anger that the people of Konoha is giving them, taking Naruto with him and joining Kumo and how he becomes The Grim Reaper of Kumo, while helping Naruto become Raikage. 1st time typing a novel so i hope u can understand, as for Flamers if u don't like, leave Action Romance Harem for Both Naruto and Kira Reincarnated M Rating in Future Chapters Smart OC Strong but Not OP MC (OP is later chapters for both Naruto and Kira) this Novel is somewhat similar to 3headed-dragon's fanfic novel The Yin and Yang of the hidden Cloud but with some changes. The author is amazing check him out in FanFiction.Net There will be a few bashing [I got the image from google, if the person who made it wants me to take it off, comments on the comment section so i can take it off]
