Wiseman returns as Yata. Sora from //Sign (and kind of at the end of //Quarantine) comes back as the lead character, Elk is Endrance, Sieg is Kuhn, Nuke Usagimaru and Rachel are mentioned in a news article, you can get an e-mail from Blackrose to Kite if you convert your data from //Quarantine over to //Rebirth, Piros and Natsume make a return, and I'm probably forgetting a few characters...
