So in this AU, it’s basically the same as canon, EXCEPT, the ninja stay secret.
it's not JUST their identities. It’s also their literal existence and history.
FSM didn’t want humans, who often misunderstood and killed Yōkai-kind, to know about the Elementals. So he kept himself secret, his two sons secret, and the people he’d later choose to become the first human-ish Elementals secret. Those people were street orphans and abused kids he’d rescued from other humans.
Elementals have basically been behind the scenes (and doing illegal stuff like underage driving) for several millennia, they’ve managed to keep secret all this time and continue to do so in this AU.
When something big comes, like the Great Devourer, the ninja fix it but there’s only eyewitnesses and no camera footage and most of the time they somehow aren’t seen by humans.
Or Jay causes a blackout to make things harder for them to be seen.
Oh, yeah. And Elementals aren’t sure if they’re Humans with powers, something between Yōkai and Humans, or just full-blown Yōkai.
They just don’t know, but they have the senses of Yōkai and they can see very well in the dark- they also have a keen sense of smell, they can follow trails. And their eyes glow, but they can control the glow when they need to. Among other things, like feeling vibrations.
Elementals also have feral instincts, though they can ignore those instincts and act human when the circumstances demand it. Lloyd, his father, and uncle all have Dragoni features like in my Headcanon #1, and they're the most feral.
If you saw my HC about the Elemental Bond, that applies here too.
The Elementals just tell people who ask that they’re a clan. They’re kind of common amongst the Realms, and to help the ninja, their clan is tiny, and sort of IS a clan, just a special one.
Said clans that do exist either live off the land or live modernly now but they all started back in old times, and they keep touch and all nowadays.
The Serpentine often receives a similar reception that Yōkai get, just less than that, so they don’t give the game up- they keep silent about the ninja.
After meeting the ninja, the Formlings, the Geckles and the Munce, and others were asked to and agreed to keep quiet about the Elementals. So does Vania, (idk how that part of Master of the Mountain works but yeah).
In the AU, other Yōkai, (Kitsune, Kappas, Tanukis, Bakenekos, ect.) are more apparent and present in this, and even most of them don’t know about the ninjas, just a few friends know.
The Elementals frequently attack and ambush Yōkai Hunters, and free the trapped Yōkai.
There’s also more mountains around the Monastery, it’s a literal mountain range, and many Yōkai live in them. Years ago they all combined their magic to create a barrier, so humans can’t get in (they just get turned around and all,) unless they’re led, and it's really hard for someone to just find their way in, but it happens occasionally.
IN THIS AU, THE SIX SEE EACH OTHER AS SIBLINGS, EXCEPT MAYBE JAY AND NYA, I CAN'T DECIDE.
Arin knows about the ninja ONLY because he’s from a village near the mountain of the Monastery, and his family is one of the few that the ninja trusted with the knowledge of their existence, because one of Arin’s ancestors, a few generations back, accidentally found a way into the mountains, and got caught in a storm, so the ninja of the time saved him.
Also all the Elementals speak Yōkai. It’s their second language, and their first language is Japanese, English is their third language.
