Just as we the readers are in a sunk cost fallacy, so too, has Nakatake has entered a really dangerous sunk cost fallacy:
1)If Uruma does NOT succeed and fails to kill Kyou, then this whole revenge plot that the manga was centered on was for nothing, and all the loss Uruma suffered chasing Kyou was meaningless.
BUT:
2)If Uruma DOES in fact succeed and kills Kyou, the end result will still be humiliatingly unsatisfying, because Uruma STILL suffered and lost wayy too much for Kyou's death to be celebrated and equal in terms of retaliation. We the readers won't see his death as a real victory.
This is bad, like unrealistically bad. Nakatake's first manga has been a trainwreck of a story, where he thinks gore, torture, rape, and murder are just "interesting" tools to progress a story: zero tact, zero consideration, zero redeeming qualities. That last one wasn't even a real jab at Nakatake. I can't find a SINGLE thing to like about the story anymore. Not even the art.
Why most interesting manga and LN adaptations were axed and this wasn't like 30 chapters ago is quite frankly amazing.
