| No, the sword just looks like that... with kenpachi's spirit power, no one should really be able to dent his sword at all. It wouldn't be surprising his raw spirit power is only topped by the commander general dude.
This last chapter was kind of surprising. It doesn't show anything new for Ken but it shows he's still got power to spare. Hopefully next chapter we will see something new. Doesn't need to be bankai. an attack or technique he's never shown before would be pretty cool (I don't think he's shown anything other than physical prowess). |
