For example: the infographic with The Magic Silver / Mercurial Mirror in it has what look like Holly Berries on the back, representing fertility. But the occult esoteric understanding is they represent the poison forbidden fruit in the Garden of Eden. In one interpretation God said don't eat that tree... that's because it's deadly poison. The mortals are only fully illuminated as to life and death when they experience death, so Satan "enlightened" Eve by having her eat of the tree and she died. Adam finds his love dead, this is how she gives him the fruit, he takes it from her dead hand, so overcome with sorrow he eats it himself to follow her into the underworld. How human life continues beyond this Garden (thought / Thoth's) "experiment" (god, magic, tech, different biology, ayys, etc) determines one's magical sphere of thought. Eg: Isis & Osiris are Adam and Eve. Osiris eats of the poison bush first, dying, he is cut into 14 pieces (pieces) his pp eaten by a fish. Isis eventually puts Osiris back together, makes a golden phallus, brings Resurrects Osiris and has zombie sex to get preggers with Horus.
These red fruit are poison Yew berries, used in witchcraft for all of history. Japanese Yew are immortal, some are over 1000 years old, duality of life & death.
Another understanding Eve/Isis takes the semen of the only man's dead body and puts it in a golden tube to inseminate herself, then uses tech to freeze/preserve Adam/Osiris's brain and later bring him back to life as an immortal.
The Generative Force and Union of Opposites is central in most mystery religions. This is a Generative force to unite Male + Female, Klaxsaur + Man, Ancient tech + New tech, etc. is central in Darling in the Franxx. That mirror has an occulted form of the Compass and Square, and the female ovaries and birth canal. The feminine sex is one symbol the Freemason version of the compass and square invokes -- but you only see that secret if you know what's inside humans (anatomy / opening cadavers, etc).
The fact that the mirror is silver / mercury and gets broken, it's given as a gift, etc. all play into another part of the story, but I'd be writing a whole script in a post, so I'll stop.

Sorry, if Trigger makes something, it's usually seen as appealing to entry-level anime fans, but it's actually just that Trigger is so skillful they put multiple stories in their plot AND still make it a good show.
