This is an old Leiji Matsumoto series from the 80s that I somehow had never heard of, despite the fact that in the US it had been released alongside the 70s Captain Harlock series, which is one of my favorite series of all time (albeit I watched it in its French incarnation, as Albator). I’ve only watched the first episode, but was immediately sucked into the mysterious storyline that starts with the discovery of a 10th planet that is on a collision course with Earth. I’ve purposely not done any more digging about the series, as I don’t want to get spoiled, but it does indeed appear to tie into the rest of Matsumoto’s stuff. Yet another series to add to my current watchlist.
