I feel like the show constantly undermines the value in saving Kayo.This was left unsaid in previous episode and only vaguely alluded to in this one but isn't the general idea: take away Kayo from home --->get the authorities to act---->get Kayo into child care and thus, presumably, beyond the reach of the killer ?
What about the other victims? Hiromi Sugita is hanging around the main character all the time but he's not going to be saved. There's not even an emotion expressed about him facing an inevitable death as far as I remember. What a bum deal. Episode eight also flashes by the other girl and it's just like...okay...? What is being accomplished here?
And how does saving Kayo help the bigger narrative? Satoru's mom is still going to die. Satoru is still going to be framed and pursued by the police. Satoru got sent back into the past after being directly set up by the killer and it's just a total disconnect to what the show is doing with Kayo. Does Satoru not want to set things right and out the killer? To fix what the killer has done to his life? He only wants to save a single person. What if he travels back into the past again and has to undo all of this Kayo stuff to fix the other things? This story is absolute nonsense.
