Actually I took a long break after long time finding no translation (Wish I could find time to learn japanese one day
) and was kind of sceptical after catching up with it over two months after having read the stuff before.
Well, what should I say. I was absolutely amazed by this ending. It made perfect sense to me, didn't seem too short nor too long and was really suitable imo.
About the frog guy: I think he was just a side appearance, and I don't think these side stories were ment to necessarily have an end. They just appear and tell a short story of a different story line, but that doesn't mean that it has to be followed all the way. I found it enjoyable the way it was.
I don't think the rest of the tournment was that important either. Obviously, it's a joy to watch fights in a manga of such quality like Shigurui, but it's not necessary to show fights unrelated to the plot.
So, why did I like this ending...
First, it was a great fight once more. It was short, yes, only a few moves, but should it really break with the previous style? The blood revenge duel between Fujiki and Seigen was exeptional for this kind of scenario already by lasting so long, would it be good showing this another time?
Second, it ended in a suitable tragedy to the whole story. What happened to the two very likely greatest fighters of their time? They put up a
brilliant fight, and people don't even notice! They just think two idiots fought... they just see Fujiki beeing unable to hold his sword (when he actually threw it on purpose as a fake to Seigen), see Seigen falling for the fake and triggering his deadly attack too early (thinking he missed because he couldn't be able to detect anything without his eyes and just stroke randomly) and conclude "a total failure, a disgrace to the lord." Seemingly they didn't even recognize what an amazing Tsubazemari one-armed Fujiki used, far exceeding everyone elses' powers.
What irony, what tragedy.
Third, it came with a great character developement. Seigen's story was suitably concluded, and Fujiki's developement finished when the duel started. To then totally crush him in that dramatic turn. Right when he finally found some respect for Seigen, he's supposed to humiliate his remains. A huge moment.
Fourth, the ending wasn't necessarily closed (what would Fujiki do now?), yet closes the plot absolutely by only leaving one person alive.
I think that it was good to conclude this story as a full fledged drama. It was a tense drama to begin with, in those psychic barriers and cruelities of a mafia-like organised samurai patriarchy under Kogan. The characters were constantly striving for death and destruction, and that what they got in the end, almost in perfection.
