Team Minato make a promise to meet up again in their next lives, only the timing isn’t so great.
Or Team Minato reincarnate into the KHR universe at different points in time, despite their best efforts. This has some lasting consequences.
It’s a Promise!: How everything starts.
Too Little Too Early: Obito ends up reincarnated decades before the rest of his team is born and gets a job as a stuntman to pass the time. (Somehow, when he finally finds his team again, they’re not the least bit surprised about the mess he’s gotten himself into.)
Minato’s Adventure Years in the Past: Minato overshoots. By a lot. Ah well, it’s not like there’s anyone else around to tease him for it. Except maybe Kushina, but he’s pretty sure she doesn’t remember. (He hopes she doesn’t remember, otherwise he’ll never live it down.)
On the Other Side: Drabbles about how everyone else is reacting to the crazy that is Team Minato.
