Episode 1 was pretty good, although I have a couple of complaints, because of course I do. For starters, I do wish translators of different versions of a story would look up how the names and technical words have been officially translated by their colleagues. Or decide on one spelling if it's the companies calling the shots. We can look forward to the Sorawo/Sorao debates now. Just fantastic.
Secondly, this is animated by the studio behind the Hanebado adaptation, so I was hoping to be blown away by the animation here, but it didn't feel that way. That's just nitpicking though.
The other issue I have is that the anime cut out so much! Not just Sorawo’s internal monologues, but also much of the dialogue and banter between her and Toriko. As a result, the episode felt rushed even before I re-read the novel's first chapter for comparison. Most notably, Sorawo’s motivations appear unclear and the anime-only viewer must be wondering why she accepted to go back to the Otherside after she nearly died.
The good news is that if the anime adapts one chapter per episode, we might reach the end of volume 3, which is what I was hoping. The OP sequence features Natsumi and a reference to the Sannukikano chapter, so that actually seems likely.
Animation aside, the technical aspects seemed good to me. I liked the music, and the sound design in the Otherside was really good. The seiyuu are great too, but that was a given.
Looking forward to the next episode!
