[Start of Audio and Visual Recording]

  The clash of the two blades produced no sound, but silence. A void colliding with a void. [Battle Analysis Commenced. Initial Variables: Opponent 'Dio' possesses speed and strength exceeding estimates by 35%.]

  But the more alarming data was not physical. [Opponent's combat style is not fixed. It is changing. It does not follow logic; it creates it.]

  I initiated the attack with a series of calculated strikes. [Classification Error. The opponent is not a 'swordsman'.]

  As I lunged, Dio stomped his foot on the ground, and a rock wall rose before me to block my attack. Then he waved his sword, and a tongue of black flame shot from the blade, forcing me to retreat. [Opponent is a multi-faceted energy user. Re-evaluating strategy.]

  I changed my strategy. I struck one of the massive charred trees with force, sending a thick cloud of black dust and ash into the air to obscure his vision.

  Dio waved his hand with indifference. A clean, strong wind blew, dissipating the cloud in a second. [Tactical deception is ineffective. Conventional means are insufficient.]

  A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

  "Alright," Dio said, and he seemed to have grown tired of playing. "That's enough."

  He looked up at the fake blue sky he had created. Then he whispered words that were not an attack, but a sad prayer, a desperate incantation.

  "O, my sky... rain for your imitator... rain for the one who thought himself your servant for a moment."

  In the next instant, raindrops began to fall. Heavy, cold drops that struck the charred ground, stirring up the smell of wet dust. In seconds, the rain turned into a violent downpour, washing away the ash and revealing the barren earth beneath.

  Then he charged toward me through the curtain of rain with superhuman speed. I tried to dodge, but my feet were slower. I evaded the fatal blow, but the black blade passed through my left arm, severing it.

  [Severe physical damage. Left limb has been severed. Grey fluid is leaking at a high rate. Initiating self-repair protocol. Estimated time for re-attachment and full recovery: 10 hours and 42 minutes.]

  I bent down and, with my remaining right hand, picked up my severed arm and held it in place for the slow healing to begin. I gripped "Ash Blade - Copy 01" tightly.

  Dio stood before me, the heavy rain streaming down his expressionless face. He lowered his sword and looked at me.

  [Analytical Note: A slight inconsistency has been detected in the movement of opponent 'Dio' as he stands. There is a flaw in the balance pattern of his left foot of 8%. Data is insufficient for a full analysis, but it indicates a pre-existing structural weakness.]

  Even he was not perfect.
