Rabu. So there’s this very, very strange reference this episode to “Sotoori”. It seems that many Japanese were a bit puzzled by it as well, but one person gave some hints about what it means. First, it seems to be a similar naming to Operation Yashiori from Shin Godzilla (which I have not seen, unfortunately). Second, it may be a reference to Sotoori-hime (衣通姫), who you can read more about here. One way or another, my guide seems to think that Akishima may have been aware of the true plan from the very start. Was she? You can decide for yourself.
PS: I meant billion, not trillion. Still a lot of Yukichis.
