I don't get how you people have so much trouble with these accounts. For rerolling, you can just go into the account settings and press "Reset account", it even restarts the game for you.

I feel like the concept of idols gets glanced over way too fast. So you just summon what seems to be completely self-aware Shadows with Persona abilities, and no one asks any questions about it? What kinda Severance bullshit is this? And they just... disappear when the story has to happen?
I'm so damn confused by this entire concept.
