#obito assures her that if they ever catch her using their techniques he can use his sharingan to compel them to forget or he can take em ou

tbh i'm always curious about the kaguya causes the apocalypse au, but rarely have concrete questions to ask. so um, what are sakura and obito's abilites like? how powerful are they, both as a team and individually? sakura canonically had healing and super strength, which are great, but I'm also a fan of aus where she branches out and learns other things, so i gotta ask. does she learn genjutsu from obito? also they survived a WHILE in the apocalypse, right, presumably they got even better (1/3)

and learned new stuff from each other? and/or from other survivors in their group? what are their go-to weapons? how does their power level now compare to people in the past? (2/3)

(3/3) ALSO! they travel to other dimensions using kamui, right. where does the kamui spit them out when they go a new dimension? somewhere randomly? (if so, how many times have they ended up dumped in a swamp, or in the middle of nowhere?) some fixed place every time? wherever obito wants? where? and can they choose when they arrive in a new dimension, or are they also just randomly spit out whenever and good luck figuring out in what time and place they are?

these are really good questions!!! i apparently wrote 1100 words in response, so: under the cut!

sakura and obito did survive a while in the apocalypse, yeah. people survived in groups–konoha especially espouses teamwork–and people took positions well-suited for them, at first, like they have been trained to do. hyuuga, inuzuka, aburame, yamanaka, and sensors were good at keeping track of people and directing the groups to safe spaces and such, for example. but people die, and at some point you stop being able to replace them

so people learn to cover those positions in any way they can. enhancing their senses with chakra; trying to recreate barrier seals that you’ve only seen and never studied; etc. people share information about what they remember. people go off and come back with clan scrolls, because there’s no point in hoarding clan information if that information will help keep them alive.

obito and sakura learn together, and what they teach other is–incidental, at first? sakura is healing someone, and she nabs a passing obito into helping her. obito can heal himself just fine, thanks to hashirama’s DNA, but–well. he has deep chakra reserves, as well as the ability to absorb and transfer chakra, so he might as well learn how to heal other people, because at some point they’re going to run short of medics, and it’s better for everyone if most people have even rudimentary medical skills

obito… okay i’m going to be entirely honest here: obito is fucking HORRIFIED at how sakura was treated as a genin. obito’s already complicated relationship with kakashi is complicated even further because he cannot BELIEVE that kakashi didn’t teach her SHIT, didn’t CULTIVATE her OBVIOUS TALENTS, didn’t direct her to anyone who WOULD. kakashi failed sakura, and obito is pissed off on her behalf, because that shouldn’t have happened!!!! obito offers sakura his knowledge Readily and Gladly because she should never, ever feel useless again. she should never, ever be given less than what he or anyone else can offer.

it had been noted in canon that sakura would have been adept at genjutsu, and he gives her techniques. they have to be adapted some, because genjutsu with a sharingan is formed differently than genjutsu without a sharingan, but sakura figures it out. she’s quick and eager to learn! and she’s GOOD at genjutsu! she learns how to conceal people and things; she learns how to subtly redirect a person’s attention so that their eyes skip over something without truly seeing it; she learns how to muddle a person’s sense of balance, of temperature, of pain.

and obito teaches her some ninjutsu, because that’s ANOTHER area where she was failed! why the FUCK did kakashi skimp out on even THIS?!!

sakura has water and earth release, so obito basically goes: okay, cool, here’s some mist techniques. here’s a few iwa techniques that i saw when i was 12 and that i picked up from deidara. you’re going to be so badass, i’m so proud of you.

sakura especially becomes more well-rounded than she was previously, and honestly kind of terrifying because she’s ENJOYING being versatile which means making use of her new techniques, but obito’s pretty happy with his end of the deal, too. his self-healing is passive rather than active, so learning how to use medical techniques and gaining medical knowledge is Actually Helpful because, hey, now he knows what the fuck is going on and now he can actually heal other people. AND now he knows how to do stuff like making blood clots! while that may not help much against kaguya, he’s not going to NOT appreciate new and interesting ways of killing people!

in terms of power, it’s hard to tell when your opponent is a Literal God, but by the time everyone else is dead and they abandon this world, they’re kind of stupidly powerful. like 12-year-old sasuke would eye them warily and challenge them to a fight in a hotel hallway because he can Tell they’re powerful, maybe more powerful than even Bane Of His Life Itachi, and he needs to see how he matches up against them. like–they don’t really escape because they’re dying; they escape because there’s nothing left for them, and staying would just mean dying meaninglessly.

weapons like shuriken, kunai, and senbon had become, increasingly, a scarcity, because making more becomes difficult and then impossible. they picked over past battlefields for weapons that they’ve thrown. not a lot of people had Many Throwing Weapons after a point

but when obito and sakura hang out in kamui, it’s not like THEY’RE going to lose weapons now, so obito pulls out some from his Long-Discarded Weapons Stash and they sort of idly brush up on their bukijutsu. is sakura likely to ever have need of a gunbei? no, but obito’s going to show her how to use it, anyway.

the mechanics of kamui in this ‘verse are like–

the sort of “neutral ground” is the space that obito is used to, the grey landscape of blocks where everything he puts inside of kamui shows up. in order to access anywhere else, kamui needs a set of parameters, conscious or subconscious.

in the beginning, the only parameters are the conscious “not our world” and the subconscious “please be empty,” so the destinations were random and without people. an empty forest; an abandoned cabin; a peopleless island.

obito isn’t USED to making use of this aspect of kamui, so at first, aiming for particular places and times would be difficult. he’d overshoot or undershoot, or get there at the right time but not the right place. but he’d get more precise about it and learn what sorts of parameters work best with what he has in mind (ex. events can come quicker or be delayed or happen somewhere else, depending on the circumstances! some events are sort of fixed in time and place–october 10 in konoha for the kyuubi attack, for example–whereas others shift–like who kumo takes to make a jinchuuriki). if he isn’t clear on a specific variable, what comes out will be random–like if sakura was like “i miss hashirama trees. can we go check that out” and obito’s parameters were just 'hashirama trees around konoha’, they could drop ANYWHERE in that particular forest and at any time where those trees exist

obito and sakura kind of–tend toward peaceful times and places, at first. they gather themselves up and put themselves back together as much as they can. they’re tired.

but then one day sakura makes a comment, like i wish i’d known you sooner, and obito thinks: but you could.

not this sakura, of course, but another one. a different one.

they find an obito crushed under rock, still alive, and obito can use his mangekyo to take him into kamui, and sakura can heal him from there–at least enough to keep him from dying, at least enough to take him to konoha.

being able to help–that goes a long way, after such a long period of helplessness and hopelessness, and when they think about it, there are so many things that they could help prevent, so many lives they can save with the information that they have now.

so they basically become S-class dimension-hopping superheroes just because
