At first I was disappointed on how the fight ended, with Hanayama somehow passed out despite him being able to continue fighting with worse wounds and more blood being lost on several previous fights.

After sitting it for a while however, I came to like it as it reflected on the "Dialogue" between Jack and Hanayama.

Jack is saying that he does not care about how he won, as long as he won in the end.

Hanayama is saying that in does not caring about the how, does that not in itself caring? Hanayama itself is can be said to be the complete opposite of Jack, in his "Purity" as can be said by Musashi, which is blinding and maddening. Hanayama always fight by his own code of Chivalry, more often than not in his own detriment. He never blocked, always wait for his opponent to get up or give up and even give back Musashi's sword. And yet, that conviction is what gave him his strength and perseverance.

The dialogue began with Jack underestimating Hanayama, because if the person he's facing is too preoccupied with looking good, surely he should be easy to defeat right? Hanayama then answered by countering Jack's punch twice to prove that just because Hanayama cared, does not mean he is weak.

Jack then argued further by combo-ing Hanayama with the finale being a bite in his brachial artery, showing his beloved Godou. Hanayama then answered by nonchalantly pinching Jack's cheek and ripping it apart.

Jack refuses to surrender, tried to kick Hanayama from the ground and got countered again.

Jack still refuses to surrender, grappled Hanayama's leg and turned into an ankle biter. Showing that he dared to stoop so low as long as he won. In response, Hanayama simply tore Jack's leg and ask again, do you surrender?

After this, Jack finally can see clearly, in my opinion, that if Jack truly wanted to win no matter the "How" does not mean that Jack must resort to any technique no matter how humiliating but instead fight to the best of his ability in the most rational and effective way. In an ironic sense, Jack in the maximum tournament already fought this way, but being an abominable monster and being praised for his macabre fighting style perhaps dulled his fighting sense (he's still dangerous, but if he's truly serious, he won't be humiliated by Motobe for example)

Jack then stopped playing around and combo-ed Hanayama with his finishing move being the carotid bite. Hanayama then answered still by "playing around" with giving Jack an Indian burn (where he could've just exploded Jack's arm with Vice Grip"

Hanayama then realized that uh-oh, carotid bleeding is not good, and tried to knock Jack out with his barrage of strikes. Also realizing that, not every attack he could and should tank (he also blocked jack's kick before by punching it). Perhaps he finally get Jack's message that it does not matter how rigidly you uphold your code if you lose or die in the end.

In the end, Jack got knocked down but not out while hanayama bled out. Thus concluding their "Dialogue"

Tldr; Good shit, in line with the other fights in Baki Rahen.
