This episode made me super angry with everyone. After 2-3 fillerish episodes, the action finally starts, and things go to shit for Miyo again. Kudo not listening to her. The trash Usaba family that let her suffer for her entire life all of a sudden showing up like you're dad's 3rd cousin after you won the lottery. Them stating "we can totally teach her to fix the nightmares, but we're not going to" and deciding things with a duel. Just overall a very frustrating episode.

I feel like her mom sealed her power to hide her from the trash family because she knew what they were like. I doubt she planned on dying, so she figured she'd be there to unseal the powers and help Miyo learn to use them when she was ready. Just tragedy that she ended up not being there, and the family she ran away from got their claws on Miyo anyway.
