Event plot for Andrea (not that we're doing much else) Miyuki: at the Zoo island will be scared and flaily and need someone to cling to for a while, please? Eventually she'll buckle up and do her best to help with the search, however. Oh, and her ghosts will probably involve semi-naked ladies, just so you know.
Ashura: will be on the Amusement Park island and will be very determined (and kickass, if need be), even if meeting his ghosts will likely result in some wibbling.
Koryuu is also part of Team Amusement Park and will bitch and moan his way through this entire event. Then he'll be mortified when he finds his ghost.
Fuu, on the Garden island, is all about teamwork and would very much like to pair up with someone. She's not really a leader, but she is an organiser, so I imagine she'd like to talk to everyone on that island and try to make sure that the different search parties cover all of the island and stay in contact with the other teams during the search.
