I've only seen 1 other person mention this so far, but this boss actually glitched out for me. I arrived at Mt. Kongo while exploring before fighting Genichiro, went through the area just fine, until I got to the part where you encounter the first Twinblade Strawhat enemies. They were just staring at me doing absolutely nothing. I attacked and they would block everything, but never retaliate. I eventually mashed my way through them, confused, and then I arrived at the Warrior. He walked out, said his lines and just stood there. Same thing as before, except this time he wasn't even blocking my attacks. At that point I actually thought it was just part of the game. Until I looked up the actual fight... And felt so cheated. Only in a From game do you get mad for NOT having to fight the boss.
