From a very early age, Naruto was familiar with the sight of blood and the female body.
Most people in a ninja village would suspect that meant he was sent to the front lines of a war while still young. Others might have supposed he lived in Konoha's red-light district, where the sight of prostitutes were common and bar brawls were a dime a dozen.
All of them would have been wrong. In reality, it was because in his head lived a nine-tailed blonde foxwoman who, all her kindness and motherliness aside, had three strange habits: the tendency to go 'NARUTOOOOOOOOOOO~!" every time he did something 'cute', the capacity to lose litres of blood from her nose at some of the really cute things he may have done, and the reflex of going into SUPPATENKO mode at the drop of a hat.
Naruto loved her, really, he did, but he had one of the strangest mothers ever.
At least, that's how Ran would be if this author actually wrote crack.

If Yakumo Ran knew the regular Kyuubi and knew his name, then if Naruto ever meets Yakumo Kurama Ran will be pushing him towards her just for the sheer amusement of the girl having her last name and Kurama's given name (albeit in reverse order).
