Well, I don’t know what I expected, but quite honestly this was pretty bad imo.
First things first, even as a VN reader I felt like the show was just suddenly whamming me with all this information about a character that I have no reason to be attached to. Suddenly dropping Shizuru’s backstory when her actual character hasn’t been fleshed out at all was an extremely poor choice (maybe a necessary one, if the anime is really only getting one cour), and it just feels forced and unnatural. Anybody who hasn’t read the VN has no reason to care about Shizuru, her past, or her relation to Guardian .
Second, this episode suffers from the same problem as all the others - the pacing is lightning fast and there’s no time for any one scene to sit and really be digested. It’s even worse here because this is supposed to be a pretty emotionally charged episode, but the show just continues to charge straight ahead and trip over itself all the while. The combination of the awful pacing and my extreme disinterest in any of the characters (specifically in the context of the anime) just completely slaughtered any sort of emotion this episode might have carried for me. As usual, there was no logical buildup - the episode starts all silly and then suddenly gets serious with little transition in between.
Third, pretty much everyone else has already said this, but what the actual hell was with the placement of the Lucia scene? This episode was in desperate need of more time - ANYWHERE - and they took a solid minute or so of runtime with an insanely out of place scene giving some foreshadowing for a character that no anime only viewer would care about. I can think of so many places that minute could have been better spent (for instance, making the scene where Kotarou remembers Shizuru’s name not jarringly fast and completely lacking in impact), but they spend it like that? Good grief…
I might actually drop this at this point. The only thing keeping me going is my adoration for Key in general, but I don’t see this getting better.
