History
Kushina Uzumaki is the mother of the series' protagonist, Naruto Uzumaki, and the wife of the Fourth Hokage, Minato Namikaze.[ch. 382] She is a host of Kurama, immediately preceding Naruto.[ch. 499] Being a member of the Uzumaki Clan, Kushina possesses a special chakra that was distinguished even among her peers, causing her to be sent from her homeland to Konohagakure to be the host of Kurama, replacing Mito Uzumaki.[ch. 500] In Konohagakure, Kushina met with Minato who became Kushina's love after he saved her from a kidnapper, leading to their marriage.[ch. 498] During her pregnancy, she had to be sent to a secretive place during labor to prevent Kurama's seal being broken.[ch. 500] However, the place was subdued by Obito Uchiha, and he released Kurama who ran rampant on Konoha.[ch. 501] She and Minato both sacrifice their lives to seal Kurama's half to Naruto, while also placing some of their chakra to their son as a fail-safe if he would break the seal.[ch. 503] In Part II, Kushina's chakra appears during Naruto's subconscious battle with Kurama, helping her son to seal the fox and to tell him the truth behind Kurama's attack sixteen years ago.[ch. 497] Before disappearing, she thanks Naruto for forgiving her about the whole ordeal of the sealing of Kurama.[ch. 504] In the Japanese anime, Kushina is voiced by Emi Shinohara, voiced by Cindy Robinson in the English version before Laura Bailey took over the role since episode 246.

Trivia

 * Minato in  Naruto . In his case, he's got  very  good reasons to panic: his wife Kushina is the host of the Kyuubi, and childbirth is the moment in which the seal containing said Sealed Evil in a Can is at its weakest; if it ever broke, Kushina would die  and  the Kyuubi would be unleashed. And it happened. Sort of.
