Allright..... I'm re-reading Histories Strongest Disciple Kenichi.... In that the master class fighters are... well master class. Everything from jumping off rooftops to walking on water and crumbling buildings to space dust.
And in The Breakers, there too we have such masters who defy the laws of physics....
Leaving that aside... If the martial artists from both the manga's were to fight each other, who would win or have the upper hand? Nice pairups:
Kenichi vs Shioon
Miu vs Jinie
Elder Kwon vs Elder Fuurinji
