Once you’ve been on tumblr for long enough, you’d be immune to culture shock for being isekai’d. There’s no fantasy world bizarre enough that you’d really be surprised by anything, it’s just “oh that’s how you do things around here”. You could get whisked away to the Land of Oz and see nothing you couldn’t shrug off. You’re already used to the concpt that anything you say might prompt the sudden appearance of a living, talking straw man who shows up out of nowhere to sing you a song about how they don’t have a brain.
