In The Future
Shikako In The Future
Police Officer: You said you're name is Nara Shikako?
Shikako: Yes.
Police Officer: And you're from the past?
Shikako: Possibly. Could be from another world. Or dimension. Or reality. If there is a difference between the two. I wonder...
Police Officer: What time period?
Shikako: Ah, don't know if you know it, but the Yondaime was Hokage when I was born.
Police Officer: Right. Of course. Next you'll be telling me you're the seal master.
Shikako: Well...
Police Officer: Why don't you go all out and claim to be Team Seven's Nara too?
Shikako: Well...
Police Officer: You can't even be bothered to be realistic about your lies? Who are the two boys that were found unconscious with you? The rest of Team Seven?
Shikako: Well...
Police Officer: We're going to have to detain you for suspected collusion with the gang whose warehouse you were found in if you don't start co-operating soon.
Shikako: I don't suppose pleading amnesia due to head injury would do any good, would it?
Kankuro In The Future
If Kankuro went to the future, there'd be a stampede approximately like if Shakespeare appeared now. Like, worst than Team Seven appearing, because Team Seven is the work of hazy, uncertain, dunno how much is true, fiction; where as Kankuro is a real actual figure whose writings (some of them) survive to this day, because of how prolific and popular he was. Centuries later, his work was still getting published: his histories did not survive so well, which some historians think is the greatest tragedy in the world, (although others say that, given his evident love for dramatization, it was unlikely to be a very accurate source) but many of his plays are almost entirely extant, and those who didn't survive in person, survived by being quoted or re-written by other, later, authors.
Actually, maybe he's not Shakespeare, he was relatively recent. Maybe he's Plato or some similar Greek writer equivalent.
MDI In The Future
Oh my god, yes! Of course it's an MDI that goes to the future, rather than one of rookie 12/13. Then, rather than clear things up, the MDI just makes things more convoluted and confusing with their rants. It's not like MDI know that much about the Rookies either. Only public information, gossip and hearsay. This, along with their unique view on them, especially team seven, makes matters worse. All previous theories are left in tatters, and nobody has any new theory to offer, only bewilderment all around. Sometimes they seem to be supporting one theory, sometimes another, and their logical leaps just make no sense. Finally, everyone agrees to ignore their rants, and continue as though they never appeared. Its a more comfortable existence all around.
And worst yet: people blame them, the paper work guys, for not having enough records of everything. As though they could do anything about that. As though they didn't have enough to do already. As though they didn't have team seven to deal with. As though-
The MDI trails off into unintelligible mutterings.
Speculation On Chakra In The Future
The dormant chakra seem fairly plausible; with all the jutsu forgotten or burnt (what little was passed on by information-security-obsessed Ninja), some remnant cults (the remnants of once great clans) teaching some vague meditation based chakra manipulation tricks (not jutsu, nothing nearly so intensive, specially with most hand-signs lost, and all relevant knowledge gone). The occasional Kekkei Genkei still pops up, is classified as a mutation/sickness, and ignored. People wonder if these mutations are vestigial from the time of 'chakra' and if every ninja used to have them to interact with their 'chakra'.
Monks, in that day and age, are not to be messed with - all that meditation gives them a better grasp on their inner chakra, which makes them faster and stronger than the average person, and if their particular monastery also teaches some basic fighting skills... Monks, in that day and age, are ironically the closest things to ninja that still exist.
Batman actually makes a bit of sense in this universe.
Also, part of the 'chakra' of the past and the chakra of the present problem is that people call the modern day equivalent something else. Different things by different people: Soul-searching, inner strength, sixth sense, etc. So they don't associate what they do with what the ninja used to do. Partly because they meditate a lot, and manage to unconsiosly move their chakra a little faster, and reinforce their body a little more than just anyone could. That's not a jutsu. That's not special. Some of them get really good at reading people, or intuition, or guessing (chakra sense). But how much of that is just good instincts/experience/intelligence and how much their inner eye? So clearly this 'chakra' thing of their ancestors is extinct now.
