This is the best goddamn anime ever. If you don't agree you are completely wrong.
I've never seen this. Is it a sequel to dunbine?
But that's not Legend of the Galactic Heroes?
Absolutely. But the dub is what really makes it amazing. It's just bad in Japanese.
Tomino said it's set in the same world.
That shouldn't matter because there's almost no relation.
Just watch it. It's a life changing experience.
