Hmm, I think well...
Hotohori's got that whole ki thing going on, plus
he's a ghost isn't he? Kenshin wouldn't be able
to even hit him if he had a body. ;P
But ok, with a body, think Kenshin would win.
Nobody can defeat him, but well, if you think
about it, it would be a draw. They both would not
give up, would fight until one person drops, and
they'd both drop at the same time.
Now, in a pie eating contest that's another
story...Miaka would put them all to shame! :)
