WMG: Vandread

The Paksis is crystallized Spiral Energy.
Okay, let's see here. Shining blue-green, endless power source, fuels mecha combination, tied into human emotion especially love... Sounds like Spiral Energy to me.
  • Perhaps it's even a post-TTGL Restraining Bolt method for controlling Spiral; Energy in order to prevent Spiral Nemesis.

The attempt to fuse the cultures of Taraak and Mejeer will fail horribly.
So, their plan is to send a sampling of volunteer men and women down to both planets and have them live together to prove that it isn't so hard? What happens if someone on either planet accuses heterosexuality as sinful, or a politician from the planet (rather than admitting to being wrong) tries his hardest to disprove the Nirvana crew/volunteers.
  • Fan Fic, of course!
  • Then again, they just fought against Earth fleet and they got atleast 1 planet where heterosexual relationships are norm close enough to supply ships. Trying to condemn few heterosexual pairs would mean they would attempt to condemn one their allies. That has vastly better fleet.

This takes place in an Alternate Universe of Legend of Galactic Heroes.
Specifically, one in which the Earth Cult's conspiracies were far more successful.
Magno Vivan is Hibiki's older sister or cousin.
In season 2, at the start of episode 7, we see Magno Vivan sleeping in her private quarters. (This is how we know she has blonde hair.) On the end table next to the bed is a picture of a family: a father, mother, young girl, and a baby. The only one in the photo who's blonde is the girl, with pigtails; the baby has blueish hair vaguely similar to Hibiki's. In season 2, episode 9, we learn that Hibiki was actually a member of the 'first generation' of colonists to arrive at Majale and Tarak, before the two genders split. Specifically, he was one put into cryo stasis to save supplies. When Magno Vivan is informed of this, she says "so that baby from back then..." with a quick flash to the same photo in her room. In season 2, episode 12, it is confirmed that Magno Vivan is also a member of the first generation of colonists. Perhaps less WMG and more canon than I'd think, but it was never explicitly stated in the show.
  • Apparently she isn't.

Einhänder is an Alternate Universe of Vandread.
Earth is run by the state of Sodom/Gesetz, a dystopian militaristic government that uses Humongous Mecha much like the Tarak. Though we don't know the culture for Selene, they use fighters capable of customizing their weapons like the Mejere's Dreads. Bonus points that all voices representing Sodom are German males while Selene has computerized female voices. Perhaps after the end of the First Moon War in the lore, one of the genders for each side was wiped out and made the other separate.
