Agree with pretty much everything in your comment, I found this episode to have no emotional weight because of how lacking the second half of the show was. All the emotional trauma and emotional growth that could've been explored was completely sidelined for the sake of supernatural fantasy stuff. So many times they would show how Miyo wasn't able to speak her mind, communicate effectively or stand up for herself and everytime I thought it would lead to some kinda growth or change in Miyo and it never really did.

As for Usuba family, I really hate how the show presented them as secret good guys, that was so weird, maybe a bit out of the left field but it kinda reminded me of wonder woman sleeping with that guy without consent in the second movie, like thats fucked up but the writers clearly don't seem to recognize it as such. The cousin trying to manipulate Miyo into marrying him and being his obedient housewife who dutifully raises their kids and never ever leaves the house is really really fucked up, but never was it presented as such in the show. The grandpa leaving his poor sick daughter to fend for herself in a shitty abusive relationship and then ignoring his grandkid until her powers manifested was also presented as no biggie, he kinda regrets it so its cool I guess? For a show about a victim of lifelong abuse this show doesn't seem to recognize what abuse is.

Overall my opinion of the show is it started strong and ended really mediocre, I really didn't jibe with the second half.
