I'd like to know more about the Alpha Kwamis, they were the first beings in the Universe, but now, in modern times, they're separated. Where are they all located? Would there be anyway for all of them to see each other again?
Cycle Duo (Tikki and Plagg) - France.
Matter Duo (Stellar and Koree) - Mexico.
Balance Duo (Graay and Prrysm) - Wandering the world.
Being Duo (Vitaa and Shii) - Hidden in outer space.
During their time here on earth the Cycle, Matter, and Balance Duo have met up many times in various places and eras. The most recent time would be the Cycle Duo and the Balance Duo meeting up in Paris when the Wandering Box passes through town, when Adrien and Marinette are about 16/17ish.
They handle these long gaps of time better than humans would due to their long lives; but unfortunately none of them have seen Vitaa or Shii since they were hidden away, which is difficult on all of them. They would need all their Miraculouses to be active in the same place on Earth for them to meet up again; or for all of their Miraculouses to be destroyed where they could reunite on the spiritual plane.
