One thing that I have really enjoyed about this show is how much Kenzaburo's previous life experience has mattered. So many isekai has somebody basically just experience a fantasy story and their past life experiences don't really matter that much (maybe they make mayonnaise or something like that). This show keeps relating Grace's actions to Kenzaburo's life experiences, so much so that he is as much a lead as Grace is.
The mom and daughter were great this episode. I hope we get their segments more consistently going forward now that the coma angle is introduced. The setup reminds me of Endo and Kobayashi Live!. If you have enjoyed this show, then that one might be worth checking out as well. I really liked that one, as much as I have been enjoying this one.
