[x] Reasoning: If we're going after the beast, Sora needs to stay with the princess, both to maintain leadership, and because her status and associated social ability are going to be important for dealing with the politics once they arrive. Additionally, while her arrows would be very useful when facing the beast, having some access to jade attacks may wind up being critical for protecting the princess. We want to have one shugenja for each group, for all of the things that only a shugenja can do. Given that, which shugenja should be with each leader is obvious. Izu could fit in either group, but the princess obviously needs to be part of the princess-rescuing group, which means he's coming with us.
