to the main Tenchi Muyo timeline. Though not the first or last, this civilization eventually performed the greatest "seeding" program in the galaxy. They seeded proto-planets so that the human genome would replicate itself and somehow even seeded cultural and technological norms so things like handheld telephone designs would repeat throughout the galaxy and similar food dishes, like curry and spaghetti, would continue almost unchanged throughout history. Tenchi's Earth has somehow turned out functionally identical to the earlier Earth. In fact, when the original solar system of the Earth from Dual is found, the entire solar system is found to be basically the same: containing a giant gas planet like Jupiter, a ringed planet like Saturn, etc. Washu explains that at one time in the past, a group of people (Kazuki's group) made such an impact on the universe that their existence had massive effects on the "Astral Sea" (the dimension where a being's "astral self" originates and returns after death) that their astrals basically replicated and continue to revive and form the base of many beings in the universe. Certain astrals are so similar to their past astral selves that they retain vestigial memories of their past life that come to them occasionally like déjà vu. Miki Steinbeck, apparently represents the closest thing to direct reincarnation to Mitsuki Sanada, and her father, Hiroshi Manada (or creator-she was an AI that developed an astral), is physically identical to Ken Sanada (but shares some personality features of Hiroshi Rara as well), a friend and rival of Hiroshi's (named Ken Raraiba Steinbeck) also seems to be the other half of this mixed up duo. By the end of GXP'''s 14th novel, Miki, another digital AI named Kirche, and D (a direct astral copy of the original D, containing all her memories- but, for unknown reasons, acts like D before she became "Dee") gain pseudo-cabbit bodies that were cloned from Fuku. With Fuku they seem to represent the most direct reincarnations of the original four girls in Dual. When the cabbit group appears in the 5th season of Tenchi Muyo! each had the same voice actors that voiced their respective counterparts from Dual. The Zinv that appears in GXP is the very same as the one in Dual and he immediately recognizes Seina as his partner. Seina represents an almost direct reincarnation of Kazuki and no others seem to share Kazuki's base astral.
