If it is just Satoru's perception, it won't explain why Kenya's eyes were red last week too. There's no reason at all for Satoru to have any suspicion of him in that scene. It definitely feels like a cheap audience gimmick.
Yeah, I think I remember something like that. I really hope it doesn't turn out to be yet another supernatural phenomenon, but even as a meta-hint of sorts it looks ham-fisted and really out of place. Satoru's time-travel ability's certainly pretty out there, but I like that the show has been pretty grounded in reality when it comes to everything else so far (sans the red eyes of ominousness).
I feel like the show possibly introducing more supernatural elements could turn this mystery into an unfair one. There have already been a couple scenes here and there where the audience was made aware of things the MC hasn't, which kind of clashes with him being our (probably unreliable) window into the world and its characters, so I'm wary of the show possibly widening the gap between Satoru and the audience's knowledge regarding things, people, places and events that could be used as hints to unveil the truth behind the mystery the show's presenting to us.
I don't even think that fondly of Rokka but I'd say that's wrong here. The larger story was always the least important thing in the anime while the central thrust of the mystery was given its due.
Yeah, I actually dropped the show exactly at episode 3 because I thought we'd be getting yet another group of heroes who have to battle against the demon king, but after reading so many episode reviews in here that told me the show was more than that I decided to jump back in, and made me glad that I did.
Even though the anime doesn't cover the whole "story", it has a mystery and wraps it up. I couldn't care less about how they go about defeating the demon king, but the whole mystery aspect was fairly well done and fun to watch week after week even though that's as far as I'm willing to praise the show, since I was really disappointed when I heard that the mesoamerican setting was something the anime team whipped up in two minutes to make the show stand out (it originally was a generic middle earth setting in its source material, which is why some characters and things feel out of place at times).
And since I'm posting here, I might as well post about...
Blood Blockade Battlefront #6-7 (and five minutes of #8)
I'm really liking that this show isn't going the boring shonen battle anime route, and instead has a mix of fun and (halfway) serious stuff going on. It looks like vampires might become a main focus soon with White's brother secretly being one (but why can't Leo realize that with his all-seeing eyes, anyway?) and that crazy amount of them being somewhere inside the mist, which I don't think is the thing I'd like this show to focus on... but then again there doesn't appear to be anything else to hold the plot together besides Leo's quest, which will obviously end up being related to vampires somehow because contrived anime coincidence logic.
