Miyamoto Musashi was the most hardcore samurai that ever lived. He was born in some shitty province in japan to a family of lesser nobility (SCUMBAGS!). He taught himself how to fight and won his first duel at 13 with a wooden stick after bludging some noob samurai to death. He had syphilis on his face this left him pretty pissed off so he just went around japan winning duels and killing people for laughs. He also liked to beat other samurai to death with a wooden oar to add to the humiliation.
We salute you Miyamoto Musashi!
Almighty Samurai Warrior: I challenge you to a duel!
Miyamoto Musashi: I'm going to bash your fucking head in with my oar bitch.
