I feel like I'd understand a lot more of this if i'd actually watched past episode 5 or so of ginga, but meh, it was dull, and not subbed, so.... Did they ever find out where ginga came from, and why the other ultra had never heard of him?
(Warning: noob questions incoming)
So, the Ultra are giant being who have symbiotic inks to a human right? Do they ever talk or anything, because ginga victory seem to be fully the human in control, but I'm sure I remember something about zero talking to his human host. Also, what is the "underworld"/victorium? Is that a new thing for victory, or has it been around longer?
