I am under the impression that with the direction the story is heading Dasein isn't some giant brain belonging to royalty, let alone related to Alita, as it was presented in Gunnm: Martian Memory (1998). So it's something else we still don't fully know yet. Through Caerula Sanguis we learn that Dasein is the creator of Necro Soldiers and seems to have a vast knowledge with brain anatomy, remote control of people, body reanimation and a lot of wealth to fund fragile proxies. It dates back way before the formation of Grunthal, the altmeister council, and perhaps even predating the birth of Tiger Sauer (founder of Panzer Kunst).

My main reasoning comes from "The Treasure of Mars" Baron Muster desperately sought after. In the final Mars Chronicle volumes Zoe (Muster's right hand woman) recollected the time they finally discovered it. It was hidden in the holy canopy, and upon entering its hidden chamber, a large shockwave hit their minds. This unknown light entity presented itself as an Emergence to the two. But Muster, the cold man he was, stood fearlessly as he could look through the illusions thanks to the state of his crumbling body. He casually remarked that he was probably showing her hallucinations through electromagnetic waves that affect human cranial nerves. This false god offered him a surgery that would cure his maske toma through molecular reconstruction. But the catch was his old memories would be wiped clean. And that was something Muster vehemently opposed. He rejected the deal, valuing his revenge on the royal Martian family for their crimes. And subsequently, the kunstlers learned about the treasure and its coordinates, all the while Altmeister Austad was in contact with Dasein through the phone lines, and working with the mysterious Gergt to secure this crematorium/morgue facility with endless supplies of corpses to probably experiment on. This sounds more than just a coincidence.

On top of that, Mars Chronicle establishes in the post New Order timeline, that there is a clone of Alita controlled by a remote device, that ended up murdering Queen Limeira. And I am guessing that this clone is either the cloned model of Keteres Alita that Figure Four received, since she couldn't hold her promise. Or, it's Alita's original organic brain she gave away to Mbadi and Super Nova, and it somehow came into the possession of Necro Soldiers upon Mbadi's death. Dasein could have used either one of those to repurpose them, and perhaps even construct another Alita via molecular or cellular recombination.

So both Dasein and the Treasure man as I like to call him, know a lot about advanced technology, brain manipulation and cell reconstruction, which wasn't so common during the Terraforming Wars, until centuries later with Desty Nova and alike. It's strongly hinted they are the same person.

I'm curious what others think, especially now that Panzer Kunst Chronicle has started its serialization.
