the 4th is definitely narutos dad trust me and Kushina Uzumaki is his mom Kushina Uzumaki had the nine tails fox inside of her madara wanted the nine tails fox spirit he knew the seal keeping the Nine-Tails within Kushina's body would be at its weakest during childbirth, special arrangements were made. Kushina would leave the village in secret and give birth in a remote location. Minato would help maintain the seal and ANBU would guard the area. Soon after Naruto was born they were found by Madara Uchiha. Madara killed all of the ANBU, Biwako, Taji, and took the newborn baby Naruto hostage, threatening to kill him as well. Minato was able to take Naruto back, but this gave Madara the chance to escape with Kushina. Wishing to use the Nine-Tails to destroy Konoha, Madara released it from Kushina's body. Since the longevity inherent to the Uzumaki clan allowed her to initially-survive the extraction, Madara tried to have the Nine-Tails finish Kushina off. She was saved by Minato and brought to Naruto, who she stayed with while Minato went to help in the village's defence.To stop the Nine-Tails' attack, Minato was forced to bring it to Kushina and Naruto's location, and both of them to its. Kushina restrained it and, already dying from the trauma of its removal, volunteered to have it sealed back into her body so that it would die with her. Doing so would also save the lives of Minato and Naruto, her thanks to them for giving her such a happy life. Minato suggested using the Dead Demon Consuming Seal on the Nine-Tails and sealing the rest of it into Naruto instead. As this would also mean Minato's death, and consequently give Naruto a horrible and lonely life, Kushina naturally objected. Minato convinced her that it was for the best, and that doing this would also allow Kushina see Naruto when he was older. When the Nine-Tails realized their intentions, it tried to kill Naruto, but both Minato and Kushina used their bodies to shield him. As Minato performed the sealing, and already at the point of death, Kushina told Naruto how much she loved him and gave him her best advice for the future; her final act in this world was to fill her son with as much of her love as possible. Minato then sealed the rest of their remaining chakra into Naruto, ending their lives. Her family name was then given to Naruto by the Third Hokage, in hopes that nobody else would discover the connection between Naruto and Minato (the 4th hokage)
