Seems like the definition of isekai is getting blurrier by the minute, even in Japan...
Everyone's possessed by slimes! You're a slime! You're a slime! You're all slimes!
Rona's story also seemed isekai-ish too with her 'internet' power lol but i guess it might seem like an isekai at first b/c "Innocent" person taking over a villainess' body" is also a common isekai trope lol (maybe they didn't bother having it being an overall 'fantasy' series b/c they didn't have any that was pure(?) fantasy as opposed to 90% isekai, i wonder if the actual isekai creators would be seething at that tho)
Also while it might be Jelly's responsibility for all that paperwork, other than being on 'suspicions' i'm surprised it's not like "Will, I trust you to handle this, my memory is a bit fuzzy on how to handle these" if not like letting all the servants see and asking for help or so if not letting the hero (assuming he isn't secretly corrupt) contribute to it instead of standing next to her or so lol
, esp since Berger did something to her core(?) and erased her memories idk how she'd be able to handle paperwork at all instead of just signing off on stuff b/c she's not hand writing documents as opposed to going over stuff which i assume are bills/letters sent to her but maybe her dad being 'doting' will take over on it
