These came in the mail a couple days ago. It’s hard to tell from the picture, but the Grimgar box has a canvas-like texture to it and the title is in gold foil. The One Punch Man box has a clear slipcover over the artbox and a big cutout that makes it look like Saitama is punching through it. The image of Saitama is the front of the bluray case.
Sound of the Sky I blind bought, as it’s an Aniplex title. I don’t want to be kicking myself later should Nozomi’s license ends and it goes back to Aniplex. FWIW, Funimation will be losing Black Butler Season 1 (another Aniplex show) at the end of the month, so if you want to own that and don’t, best get while it’s still readily available. Otherwise, you’ll have to deal with the secondary market (tracking down out-of-print releases is a PITA) or Aniplex prices, should they re-release it themselves. Though, I wouldn’t hold out for an Aniplex re-release, as they’ve shown that they don’t really care to release backcatalog titles. Heck, there’s some newer shows they have the license to that they never bothered to release in the first place (Samurai Flamenco, Mushishi Season 2 and so on).
