"The Orange Spark" (オレンジ色の輝き, Orenji-iro no Kagayaki) is episode 246 of the Naruto: Shippūden anime.
Naruto's initial attack is ineffective against the beast and the beast appears to pins him with its hand, however, it's a shadow clone. The real Naruto being hidden behind Eight-Tails' tentacle. He flips the beast over and launches a Rasenshuriken at it. He immediately tries to separate the Nine-Tails' chakra, but the beast's hatred and malice begins to fill him. While in the training chamber, B alerts Yamato who begins to attempt to suppress the Nine-Tails. As the hatred fills him he is reminded of the people that spurned him in his childhood but a small gentle voice rings out telling him that he could stay there. With that, Adamantine Sealing Chains erupt from Naruto's body and restrain the Nine-Tails who recognises them as Kushina Uzumaki's. Within Naruto's mind a kind-faced woman with long, bright red hair appears before him who Naruto initially believes to be the Nine-Tails trying to deceive him. After Kushina punches and corrects him — realising who she is — an emotional Naruto greets his mother. With this, the two begin to talk and Kushina tells Naruto of her youth and how she fell in love with Minato Namikaze.
The image of Naruto and his parents that appears after he gives his nickname is the cover of volume 53.
In this episode, the fact that Kushina migrated to Konohagakure is played on very heavily. She even stated that she didn't hold much hope to be rescued when kidnapped by Kumo-nin. However in the manga, this is not the case as she told Naruto that Konoha immediately sent out a search party to look for her.
