Speaking of parallels, I actually a few days ago, regarding the past few chapters not including 634, someone on another forum asked me why do people go on about the parallels, how exactly do they matter or advocate pairings? This was a NH fan who was surprisingly unaware of the stuff but I told her its not really that they advocate pairings, its more because they serve as a story model of what could have occurred for Team 7 if things had been worse or if they had given up. I told her the parallels do not make the characters from Team 7 to another the same though, we say parallel because the characters of team 7, though we followed their journey and saw how Naruto, Sakura, and Sasuke changed over the series, as the story went on we see others like the Sannin, Team Minato, and so on, we see their actions, desires, initial team set ups, similar event patterns, basically a lot of similar stuff happens between characters but each character is still their own indiviudal different person. I said team 7 was not the only one with parallels, others could include Neji who died on his own choice like his father did or how like Asuma lead team 10, it was reminiscent of how the Sarotobi clan actually had the Yakamana, Nara, and Akamichi clans as subordinate clans and close allies.
For team 7 though, its been the whole ordeal of having relationships between the Sannin and team Minato. In each team, something happened to them that in a way corrleates with the situations of team 7.
For the Sannin,
Jiraya like Naruto started as a talentless goof, loved Tsunade, became best friends with Orochimaru, however he could not stop Orochimaru from abandoning the village or help Tsunade when she lost her loved ones. He eventually gave up only remaining in contact with the leaf following Orochimaru's and Akakstui's movements. This parallels Naruto because he wanted to save Sasuke and he loves Sakura, but because he remains noble to Sakura for the promise, he does what he can for her and her happiness, just as Jiraya did for Tsunade. Both Naruto and Jiraya wanted to save their friends from paths of self destruction.
Tsunade was considerbly smart, she started the medical system and became a prodigy for this. She eventually however lost her younger brother Nalwaki to war and her lover Dan as well. This parallels Sakura because she did become a great medical ninja, but the other reason is because Sakura "lost" her loved one like Tsunade, with Sasuke leaving, Sakura's love left physically while Tsunade's died. Both in a sense have their loves left elsehwere.
Orochimaru was a genius, gifted, and talented, just like Sasuke. Yet after his parents died Orochimaru became obsessed with obtaining power and forbidden jutsu. This is a very easy parallel to Sasuke, power. Orochimaru wanted power for his own simple desire but also immortality, Sasuke wanted it for revenge on Itachi, both out of losing their families to some event.
The sannin's fate more or less repeated and represented the same ordeal team 7 faced at the end of part 1. For the sannin it was never resolved but their own failure has set up the chance for a redemption in the way team 7 can succeed. The sannin never solved their problem though, this can be different in the case of team 7.
Team Minato, resulted as a parallel we can identify with the same basic outline as team 7 first had.
Obito- yes the Naruto of the group, clumsy and not as skilled as the talented guy, but he had a heart and good will. Obito loved Rin who loved Kakashi. Yet he sacrificed himself and after meeting Madara became a corrupted physco.
Rin- Obviously the Sakura of the group who loved the talented guy, was a skilled medic, and often acted as the diffuser when Obito and Kakashi acted up. She admitted her love to Kakashi but kakashi told her not to love him, that he was not worthy after Obito's sacrifice. She ultimately became a weapon for the mist and killed herself at kakashi's hands voluntarily to protect the village.
Kakashi- Was arrogent and cold but skilled like Sasuke. He had to learn the hard way though, obitos words changed him before obito himself became twisted. He promised to protect Rin but failed as she killed herself. Unlike the rest of the parallels though, Kakashi is unique in that he has a second chance, to correct his mistakes with team 7 and Obito.
Basically team Minato represents an opposite fate, a dark situation for all of team 7. Naruto could have ended the same as Obito, Rin had to learn the hardship of how one who loved her died and how the one she loves does not think he is worthy at all, Kakashi became a better person but at the cost of Obtio "dying" and Rin sacrificing herself causing him to fail in his promise to protect her. For team 7 though, their fates are standing opposite right now, Naruto has tried to save the world opposite Obito destroying it, Sakura will hopefully discover her feelings and obviously not die, Sasuke is still going on his own motives which can cause trouble opposite Kakashi who for a long time has been focused on the wellbeing of others. This one does not seem to make as much sense but the basic details are there for this to be a connected similarity. Sakura being a medic, having the same love pattern, make her paralleled with rin and her fate (which is to be opposite like Naruto's to obito and Sasukes to kakashi) is come to terms with her feelings and obviously, not die.
Now after I said these, the NH fan asked the whole deal about Minato and Kushina, I gave her the basic outline about how Kushina first appeared, it drove some fans into overdrive, there were similarities, and people pinned it on Sakura and Hinata. i said how unlike the other 2, the parallel with Minato and Kushina is the only one applying to an actual pairing. Basically this was a unique parallel because this was something only applying to Naruto and Sakura, not all of team 7. She asked how it worked and it was like this:
Naruto - Minato: not only because of looks, also because of battle talent, desire for hokage, and to protect his friends. Also helps that several times in the series other characters like Kakashi and Jiraya have envisioned Naruto as like Minato. Even Jiraya advocates this to Tsunade before going to the rain village. Its also due to how Naruto had early interactions with Sakura like Minato with Kushina, this makes Naruto have more on Minato's side.
Sakura - Kushina: this was what many fans debated on but I told the NH fan this and it was a very simple one. Sakura and Kushina are paralleled for a lot of reasons, looks aren't even the start, there is also how their own personalities are similar and especially their childhood backgrounds, both had a feature they were embarrassed with, didn't like the blond who liked them, both blonds liked a feature on them they hated, had tempers, etc. But over time both grew to respect the blonds who liked them. 631 made this much higher and just thrusted this one forward.
In all respect, Naruto has traits form both parents and his personality is like Kushinas but we see more advocation towards Minato so in this case, the Minato parallel is dominant in Naruto. In all situations too, not all characters had the same personalities as their parallels, Rin was a parallel to Sakura but had no temper. Even then Sakura still has traits like Minato such as both being ordinary, very smart, and considered prodigies in their respective talents. What is unique about this setup though is Sasuke has no parallel, because he has not been focused on romance at all (save from Sakura's point of view) I consider the fill in parallel slot for Sasuke in this group to be Itachi, simply because both had reasons for why they would kill and preform thier duties. They both became missing nin for a different purpose, the parallel though is Itachi chose to become what he was, Sasuke did it and lost track of why he did it in the firstplace.
I explained these to the NH fan, it was for clarity, no issues whatsoever. She was surprised she had not noticed similarities like this and that this was a part of a story element. As of chapters 631 and 634, the Sakura=Kushina and Team 7=Sannin parallels were confirmed in full.
