Description
Babel I, an extraterrestrial being, crashed into ancient Mesopotamia 5,000 years ago. Partnering with the ruler Nimrod, he attempted to construct the Tower of Babel as a beacon to summon rescue from his homeworld. The project collapsed under the technological constraints of early human civilization, compelling him to abandon his escape. Resigned to permanence on Earth, he assimilated into human society, siring descendants to perpetuate his lineage and preserve his advanced knowledge.

He established a hereditary succession system demanding psychic prowess in his heirs, granting access to the Tower’s concealed systems—a repository of alien technology and a surveillance nexus monitoring Earth. The tower’s AI rigorously screened candidates, barring those lacking power or moral integrity. Yomi, a rejected aspirant, emerged as a vengeful rival intent on seizing the legacy meant for Babel I’s true successor.

Centuries later, Babel I’s genetic heritage surfaced in Koichi, a Japanese teenager designated Babel II. Inheriting superhuman intellect, physical enhancements, and psychic talents, Koichi became the focal point of his progenitor’s plans. Though Babel I’s physical form perished long ago, fragments of his consciousness intermittently merged with Koichi during crises, temporarily augmenting the youth’s abilities.

Three dormant robotic guardians—Rodem, Ropross, and Poseidon—awaited activation by a worthy heir to shield Earth from existential threats. Babel I’s influence rippled through human history: the CIA harvested his genetic code to engineer artificial superhumans, while adversaries like Yomi plotted to exploit his technology for conquest.

Existing only through historical echoes and the actions of his descendants, Babel I’s legacy fuels conflicts over humanity’s stewardship of his power, intertwining themes of destiny, ethics, and the weight of inherited purpose.
