Fifteen's POV: I found myself in the ruins of a once-great city. The air was thick with smoke and the rubble underfoot made me wary of my footing. I could hear footsteps approaching. I readied myself for battle. The figure emerged from the smoke. He was massive, towering over me with a weapon that glinted in the dim light. He introduced himself as Last Stand and demanded that I surrender. I unsheathed my katana and replied, "I don't do surrender, Last Stand." He charged at me with immense speed, his Sword of Wind already slicing through the air. I jumped off a nearby wall to dodge his attack, but he followed me with ease. We clashed swords, and I could feel the force behind his strikes. He was strong, but I was experienced. I deftly parried his blows, trying to find an opening to strike. Last Stand kicked me back, and I stumbled. As I regained my footing, I saw him dash towards me, his Sword of Wind glowing with energy. I narrowly dodged the attack and countered with my Dragon Dash, slicing through time and hitting multiple enemies. But Last Stand was unfazed. He activated his Blade Dash, and countless energy blades formed around him as he slashed his Sword of Wind. It was impossible to dodge them all. As I struggled to fend off his attacks, I could hear him taunting me. "Is that all you've got, Fifteen?" he said. "I expected more from a war veteran like you." Enraged, I used my Super Clairvoyance to physically experience thousands of different ways to fight the enemy and all respective results. Using this, I executed him. In the aftermath, I stood over Last Stand's defeated body. The victory was mine, but at what cost? My body ached from the intense battle, and I could feel the rage still pulsing through me. I turned around and disappeared into the smoke, ready for whatever the dystopian earth had in store for me next.
