For the record, adamantine also means unbreakable. It’s a positive connotation of strength.
(It comes from Greek mythology, “adamant” is a mythical material in Greek mythology; a certain hero was given a certain sword by a certain god to kill things. It’s similar to Mithril or other “magical” materials or diamondoid in sci-fi. Incidentally, our word “diamond” comes from adamant…)
As much as I hate to admit it, everything up to the Pleasant 10,000 Years it was better than everything that came after it. It kind of feels like the story ended with a whimper instead of a bang, but eh. Such is life.
Fr, wasnt bad enough to spoil the rest of the story like mass effect 3 but could've been better for sure. I still dream of a second season for the anime tho
