Ohta is in love with CobaltThere's a serious Burns-Smithers vibe between those two. The devotion and concern, in a race founded on cruelty, torment, and backstabbing? The way Ohta keeps running to Cobalt like a little puppy dog? Come on! If this is a deconstruction of Sailor Moon more than any of the other Mahou Shojo shows, why wouldn't there be analogues to Zoicite and Kunzite? Plus, there's a villain named Cobalt in the anime series Iczer One, and she's the first villain the heroine kills, a high-ranking officer of the enemy whose death moves her lover Sepia to take up the battle in her place out of grief. However, in this case, Ohta makes the sacrifice so that his superior officer and secret object of desire may live.
The human version of Ohta is bi-curious, but can't act on it; his Yamiko counterpart was free to seek the love of a man.What do Yamiko do? Act on their template's bottled-up desires and impulses. They are id incarnate. But even after being given self-restaint by the priestess, there would have been nothing stopping Yamiko Ohta from seeing a male lover. His human counterpart had a wife and children, yes, but the yamiko was single.
"Magic" still existsThe properties of the universe that allowed the priestess to perform her experiment logically still exist. Therefore, there's no reason such things would be physically impossible in other circumstances. Given enough time and enough people, it's likely that someone will do something with magical results.
Aki is not a lesbian, but a Deconstruction of Everyone Is Gay and the common fan fallacy of seeing all forms of love as only sexual.So she deeply loved Himei. The Greeks had different words for romantic love (eros) and friendship (philia). It's entirely possible for Aki to love Himei in a deep, profound, non-sexual way. It's likely that this Magical Girl Deconstruction would show how messed up the incapability of loving in any way but sexual would make people. The thought that her feelings must be romantic deeply distressed Aki. Her not being truly lesbian would also account for her relationship with a girlfriend in the "Where Are They Now?" Epilogue being on the rocks.
Sailor Nothing leads into Kingdom Hearts.For the full explanation, see its entry on the Kingdom Hearts page.
Yamiko are sapient Unversed, akin to VanitasI'm at a loss to explain why they don't all have black hair and gold eyes, but the rest of it makes quite a bit of sense.
Yamiko are created using a person's ShadowYamiko reproduce by drawing out a person's Shadow and infusing it with their own essence, turning it into a similar but distinct creature. They skip the part where they try to convince the host to accept them back, instead immediately going berserk. This would mean that a Yamiko cannot be created from a Persona-user, as their Shadow has already transformed into something else, and isn't willing to be separated from it's other self. It also opens up the question of what would happen if a Yamiko was create from someone who latently carried the Wild Card.
Sailor Nothing takes place the Madokaverse.
