I don't think it'd be as noticable if there was more out, or it came out more quickly(it's actually somewhat following the standard wuxia format of dumping characters for episodes on end for a side story, then coming back to them), but vol 4 came out somewhere mid-last year, and Amazon doesn't list Vol 5 yet...

And yes! Why have we not seen that guy since the first volume!

I see you've fixed that "lack of Byakuya icon" problem...
