History Fanfic / DejaVuNoJutsu

* ForWantOfANail: Natsumi’s knowledge of the Naruto series has helped her change a number of events both voluntarily and involuntarily, so far [[spoiler: Danzo is dead, Kakashi has a sister, Konoha and Sand are stalwart allies and the Kages are aware that someone might be controlling the Mizukage,]] among other things.
** Because Natsumi took control of the Academy (which eventually became Nara jurisdiction) and screwed around with the genin teams barring Minato's canon team, [[spoiler: Senju Nawaki never died like in canon nor expressed an interest in ever becoming Hokage. As a result, Tsunade opposed Dan's belief that there should be a medic on every team, citing her sensei's reasoning, and the two are unable to get along, hence they never became lovers.]]
** Thanks to [[spoiler: Komushi]] attaining a sealing specialty during his apprenticeship with Natsumi, [[spoiler: Sasori never left the village or killed the Sandaime Kazekage (Satoshi). Thus, when Suna needs a jinchuriki and necessitates sealing it into Gaara, whose father, the canon Yondaime Kazekage, is the Sandaime's son, Komushi is the one designated with sealing Shukaku into Gaara and prevents the faulty seal that caused all of canon Gaara's problems from being used. Thanks to that, Karura survives the sealing, and is able to prevent her husband from destroying her youngest son's childhood. And since Sasori never left, it's implied that ''he'' will become Yondaime Kazekage rather than Gaara's father. A side story confirms it in fact.]]
** In going with the above point [[spoiler: thanks to Natsumi saving Eri, not only did Sakumo live longer, he didn't end up on a mission or situation where he would kill Sasori's parents.]] Though it's never flat out stated, the fact that [[spoiler: Sasori has parents is a major contribution to why he doesn't go rogue.]]
** Due to Natsumi making crib with powerful protections for her friends [[spoiler: Hinata is never kidnapped]] and Hizashi doesn't die.

* SenpaiKohai: Minato calls Natsumi Sempai.

* AsskickingEqualsAuthority: How all Hokages get their position, and the reason the Military Police is scary.
-->[[spoiler: Natsumi: Part of the problem with the Uchiha shinobi clan and the others was that the Military Police were scary. They ''had to be'', ninja wouldn't respect something that wasn't possibly lethal to them. It was why a kage was the biggest badass of them all, an S-rank was a dream come true for most the ninja corps, and getting a bingo book page to yourself was a celebratory event.]]

* SempaiKouhai: Minato calls Natsumi Sempai.

* WidowWoman: [[spoiler: Eri, after Sakumo's death]]

''[[https://www.fanfiction.net/s/9255749/1/ Déjà vu no Jutsu]]'' is a SelfInsert ''Manga/{{Naruto}}'' fanfic written by Vixen Tail (author of the ''Manga/KatekyoHitmanReborn'' fanfic ''Fanfic/RussianRoulette''). It is available at both [[https://www.fanfiction.net/s/9255749/1/ FF.net]] and [[http://archiveofourown.org/works/1018305/chapters/2024813 AO3]].

* SurprisinglyRealisticOutcome: It's actually extremely difficult to impossible for single parents balance active ninja duty and parenting. Since a lot of well-paying missions are outside the village, the single parent has to pull a balancing act on getting enough income and raising the child. For Tsume, she pulls this off because she is the head of her clan, who support her and has her many friends baby-sit when she's on duty. For Mana Mesuji, Natsumi's mother, who had no family or friends to help or support her this was nearly impossible to pull off and she ended up killed when she overstretched herself, leaving her daughter an orphan.

* AdultFear: Having your defenseless wife and baby threatened in their own home. Being attacked when you're at home by yourself. Especially when its found out that wives of affluent clans were deliberately being targeted.
** [[spoiler: Getting kidnapped with threats of losing your unborn child if you do not comply.]]

* IncestIsRelative: [[spoiler: The Kurama clan]] frequently has members marry their cousins and do not care to stop. It bites them in the ass as they are so inbred, the bloodline doesn't manifest anymore and the clan is dying out. The children who have the bloodline often don't live to see adulthood. So when they find out [[spoiler: Natsumi]] is perfectly healthy, [[spoiler: might have their bloodline and is pregnant]] they get very desperate for her to join their clan as she is their last hope. When she repeatedly refuses because they ignored her since childhood and she knows that they only want her because they have no choice. [[spoiler: They kidnap her and plan to make her a breeding slave.]]

* MismatchedEyes: Natsumi's eyes are one light-blue and one light-green, which she inherited from her mother. [[spoiler: There's been hints that her different colored eyes might be somehow related to her reincarnation.[[note]]They are. See the {{Foreshadowing}} entry for details.[[/note]]]]
** [[spoiler: Shikamaru ends up inheriting his grandmother's eyes, one light-blue, and one yellow.]]
