No one has stated anything as of the moment as such I don't know what they're doing however as it stands Espionage/swordsman is my own character Natsuo. He is intended to function as a spy when needed and if you've played MMO's a 'DPS' when needed. He mainly uses his katana but he does know how to use daggers if need be as a back up though he is significantly weaker in that regard. 

On the NPC side Kotoro is an NPC specializing in rapid firing with fire arms and he can do repairs on weapons when needed due to his training.

Nako is a general jack of all trades type though she does prefer mid range combat and uses a Kusarigama. Call her a ninja if you will.

The last two are fill holders and will serve as 'other' members so their places aren't all too important.
