So Nageki will be The Ghost. He won't be very happy about that. While it isn't a secret, it isn't something he really wants to introduce himself as.

Also, being trapped in a tavern with everyone else is going to irritate him, so he'll probably end up venturing outside at some point. He's normally good at recognizing danger (not to mention his previous experience with someone who collected lost souls), so I'm not sure if he'll end up getting lost or not yet. If he does, he'll end up consumed by dark thoughts and turn into a tree. If not, he'll probably spend most of the event trying to stay near his friends.
