Introduction: The Perspective of Galactic Political ScienceFrom the perspective of “galactic political science” — a framework that transcends conventional geopolitical analysis — the hypothesis that the structure of the “Shadow Imperial House,” situated in the very depths of Japan’s national polity, is intimately connected to the power struggles of extraterrestrial intelligent beings (ETs), has emerged as a grand narrative illuminating the history of humanity and the origins of the soul, far beyond the realm of mere conspiracy theory. This report treats the three great divine lineages of Japanese mythology — the Tenson-kei (Celestial Grandson lineage), the Tenjin-kei (Heavenly Deity lineage), and the Chigi-kei (Earthly Deity lineage) — as reflections of ET forces representing “people from beyond,” identifying them as the three powers of Orion, Sirius, and the Pleiades, which form the contemporary structure of global dominion. It explores in depth the reincarnation processes of Starseeds and the psychological and spiritual backgrounds of “falling to the dark side.”
