Person on the far right looks like Izanami disguised as the gas station worker. They're in the P4 column too, so I'm going to tag it, but feel free to remove it if I'm wrong.
This is a bit old, but for the sake of getting it done, I'm adding notes to all the characters. Help would be appreciated, especially with the P1 characters. Since people are having a difficult time finding some characters, I thought this would be a nice gesture.
Fixed up a few noted characters and added notes to unlabeled characters. Wasn't sure whether to add more to 'Time Count' or just leave him spoiler free. : )
