Orochimaru has a white-furred fox that has been with him since he was a child. It is one of the last two things left to him by his parents besides life.
The other is magatama-shaped earrings
Not long after he rebelled against the village, his fox also died, leaving him alone.
He began to study the art of reincarnation from dirty soil
When Konoha's plan collapsed, he defiled all previous Hokages. In the end, he failed. He was left with a pair of hands and could no longer use ninjutsu.
But he was very happy, because his family was finally sealed into the scroll by him, and the fox that had suspended time came to life and even turned into a baby... The baby with fox ears and tail was like a fox demon who had been cultivated
And it also has some connection with the Second Hokage, because when he retreated in a hurry, he seemed to have taken something from the Second Hokage. Later, during the Fourth War, I discovered that my fox really had a different relationship with the Second Hokage.
Faced with the resurrection of all previous Hokages except for the Second Hokage, and the fox who suddenly grew up from a child and became exactly like the Second Hokage, except that he looked 16 years old.
Orochimaru said: It doesn't matter, no matter what it becomes, it is the fox I raised, and no one can take it away, not even the God of Ninja! !
