eh; ... uh.. truthfully in my most candid of answers I expected this to be a 1X1... and in my rps I do expect original characters unless the rp is a fandom of something. 
However seeing as this is Kyoto's themed rp and he had written the first post himself. I'll leave the ultimate decision to him, in which case, I will adapt accordingly. 
I am still debating on whether or not to put in two more characters, right now im just barely getting comfortable with shu.
