Saint Seiya Hades Chapter Inferno
It's mostly about Seiya & Shun fighting. Sadly, we don't get to see Kanon like I was hoping for, but we do see Saga!. They added a scene about Orpheo, where we see him playing lyra to the Kyoukou and some of the gold saints, back at Sanctuary years before!. The gold saints we get to see are, by order of appearance: DM, Saga, Shura, Aiolia, Shion or Saga as Kyoukou.
