Well I ended up having a nice laugh!
Episode 13 has me going "the fuck is this
" then "No idea but I can't take my eyes off it
"
Okada handled the first 6 episodes herself,others have taken over since then.
Episode 11 is the exception,it kind of showed too.Okada loves her inner monologues,more so than other writers,so when they show up it can be a sign she's writing the episode herself,for exemple in episode 11 just before Zessica arrives and drinks Amata's juice , him and Mikono have this sort of dialogue through inner monogues.Very Okada-esque.
