[[WMG: There is the possibility that (quite obviously) the world of ''Manga/{{Naruto}}'', AfterTheEnd, will be this world.]]
With the Hyuuga becoming Iga and the Uchiha (how that happens, I don't care) will be Kouga.
** Considering how much Kishimoto (cough) borrowed from this manga, it would be plausible.

[[WMG: Otherwise, it is the Prequel to Manga/{{Naruto}}.]]
The eventual thinning out of ninjas from both Iga and Kouga clans brought about the demise of the art of ninjutsu, becoming far more a hidden art than it is. The wars of this world, in a sense, became [[CrapsackWorld the "miserable" situation]] [[spoiler: that [[EldritchAbomination will be exploited by the Ten-Tailed Beast]]. And then the last of the original clans, both a product of the marriage of Iga and Kouga, will be the [[Manga/{{Naruto}} Sage of the Six Paths]].]]

[[WMG: Oboro actually has no eye power.]]
Is just that she's ''so'' {{Moe}} that even the enemies' powers stops working in order to admire her.
** KAWAAAAAAAAI!!!
