Actually, i think Shigure is only there to fill the space of weapons master and more importantly...to provide fanservice. I mean, cmon, see through fishnet?
Yeah... Though I expected something along the lines of "World of more Ero and Ero." Guess the "joust" is over... Shame. One of my favorite chapters, I think. ;) Another is the part where Kenichi imitates his masters.
