Ps: Enjoy ypur trip!!

I hope there will be a next season but that Thor must change back again to being tough like when he was as a kid.

And upon the Iceman/Hakuoro’s god possessed genes, every humans ancestors (aswell as Mikoto and Mutsumi), were created.
Thus he bees the father of all.

As for why he calles Eruruw Mikoto, is that he probably thinks (or perhaps she is) the reincarnation of Mikoto.
And Kamyu is probably either possessed by Mutsumi or her reincarnation aswell.

And Aruruw just calls him father, cause he is sort of similar to her dead father.

From Iceman’s genes meny meny “test subjects” were made, including Mutsumi and Mikoto.
When Mikoto and Iceman escaped that lab with the help of some professor, (all or most) of the test subjects were released so Iceman and Mikoto would have a better chance to flee (exept Mutsumi who coudnt escape).

Then Iceman and Mikoto were recaptured, Mikoto was dissected (and they were stupid enough to tell that to Iceman with a unconcerned tone).
Iceman then went on a rampage and granted the wish of some scientists for a body that wont die (they were turned in to something like a meat blobs or slim monsters).
Then Mutsumi sealed him, cause he(Iceman) didnt wish to cause such horrors…

Those test subjects who escaped are the ancestors of all the people upon the world (in which the tale takes place, as far as i know).
Thus you could say Iceman is the father of all humans since from his genes all the peoples ancestors were made, (and he killed all the scientists, sort of,
well none of those blobs can impregnate anyone, and even if some were over looked, normal humans coudnt live in the outside world).

As for who is Iceman.
Iceman was in his time a archeologist or a scientist, who found a fossil of a god, he was killed near the fossil and his blood awakened the god,
the god took possession of his body but he was sleepy soo he went back to his slumber (in the body of Iceman).
Alot of time later.
Those scientists i spoke of earlyer who made Mutsumi, Mikoto and the others found Iceman’s body and found that he could live in the outside world, while the scientists could not.
(They tried to remake his mask, and also make people capable of living on the outside world.)

After Mutsumi sealed Iceman, time passed (i dont know how much) and then he awoke.
The Iceman scientists (human side) and the god disagreed with each other. (or perhaps they were merged together and simply had a split personality, take it either way you like)
And split themselves in two, they fought furiously and separated, then one side stumbled upon Aruruw (being near dead) and Eruruw.
He made a contract that Eruruw will heal his wounds for eternity and he will save Aruruw’s life.
And his will was done, then he turned and capsuled himself in human form, Eruruw carried him home and he was later named Hakuoro.

Diy in the other hand was a philosopher who threaded sacred ground to where the now Hakuoro’s other half slept.
The other half possessed Diy.
Thats why one half has wings, and the other is the possessed scientist from eons ago, he was the original vessel, thats why he has the mask, i believe.

In short:
Iceman = Hakuoro.
Hakuoro’s human bosy was a vessel for entire Witsuarnemitea, before he split in 2.
Now Hakuoro’s human body is a vessel for one Witsuarnemitea.
And Diy’s body is a vessel for the other half of Witsuarnemitea.

And upon the Iceman/Hakuoro’s god possessed genes, every humans ancestors (aswell as Mikoto and Mutsumi), were created.
Thus he bees the father of all.

As for why he calles Eruruw Mikoto, is that he probably thinks (or perhaps she is) the reincarnation of Mikoto.
And Kamyu is probably either possessed by Mutsumi or her reincarnation aswell.
