Okay first things first. Masaki your character is accepted. I would have liked a bit more detail in the backstory but if it is your wish to keep that hidden for now then that's okay.

Second of all, as far as I know these characters are involved in Haven;
Ben, Sanguin, Izzy, Akal, Venn, Rucks, Leef, Vendrick and Fawn. That's like half of the roleplay haha...

Haust is on some mermaid hunting mission of some sort, I'll have Yukiko join him on that for some interactions.

Vero is planning on taking the bank robber one, but I think so that you're not roleplaying alone you should just jump into the Blue Pegasus quest.

Everyone else (Mary, Zy, Kyuuten, Candy) should go on the Blue Pegasus Quest which is also another story relevant one hooray.
