I cannot wait to find out about the guardian spirits. They've been this powerful presence that just showed up, but now they're watching her.
The teacher not being super on the up and up is interesting, too. He's not just traumatized by his mother's spirit, but he's also at the very least capable of seriously harming another person, if not outright fucking killing them. He could've turned him into the police, but he tazed him and did god knows what afterwards cause no one saw him again. It's a reminder that this world is still really dangerous. I love it, everything feels like it has huge stakes which makes things like Miko using what she thinks is her last way out in a selfless manner hit hard.
