This is probably very much "Season 2" for all intents and purposes. When the "Side Story" starts getting into the triple digits, you'll know this is the case.
Just because it's reflective and looks metallic doesn't mean it's solid metal through all the depth. Glass/Plastic with a thin metal layer achieves that look very well, eg: one way mirrors, visor on firefighter helmets, ski goggles…
Opher was a virgin.
Even if he wasn't a virgin, it took Hoss and Cheong, the strongest people in the world, wielding a sword made of Purexclusivium to put him to near death.
A bunch of snipers wouldn't have done anything when Opher could oppenheimer an entire area code by himself.
Thank you for the translation (Koko's energy and boobs give me life. I love her so much that I wish squeezed my crotch with her butt with everything she has).
