It’s a very good chapter. Takezo/Miyamoto is a good character until now, but I think he can turn into an amazing character with the story progress. It’s sad to see Matahachi in such a situation, it would be good if he’ll go with Takezo.
The fire stopped the fight, that end in draw, but Minamoto now knows that is not stronger the two brothers!!! Lucky? in my opinion, yes, he was lucky!!!
This was always such a clever way Inoue sensei made Musashi leave the fight to grow stronger by the sword. Yoshioka school got shook up and they're definitely going to be in a training arc of their own... well except for Seijuro lol
