Anyway tl;dr this ain't Vagabond. Vagabond has a big background suspense about the fight that we know will eventually happen (except it won't because Vagabond is abandoned lol), whereas this story has a big suspense about the fact that we have no idea what will happen.
I wonder if even Musashi has plot armor or not; his feats are certainly less impressive than some of the shit we've seen from other fighters already, since he's a very young inexperienced Musashi, so by the themes of the story it would be totally rational for Musashi to die. Then again, rereading chapter 7, he "awakened" pretty hard in his fight, tho he'd still be in over his head against some of the established experienced top tiers in the tournament. Page 58 shows that he'll fight Fuma Kotaro next (narratively not insanely top tier i think, tho she did beat a strong old guy in an upset), and then the winner of Yagyu Munenori (insanely high tier afaik) vs Nagamitsu Hino (ludicrously high tier), so at least he has Fuma as a stepping stone to try to get up to speed before the insane-tier opponent?
Very interested in who wins the next fight between an unimportant-looking guy with the nickname "One Hit Kill" and Yasuke the African samurai. Guessing and hoping Yasuke wins (rather than him jobbing to "One Hit Kill" just to establish his One Hit Kill status), but then who wins in the later fight between Yasuke and this ninja who just beat Kojiro?
