Darren instinctively backed away from Aizen who slowly walked towards him as he drew out his black katana. However when it was fully drawn out it started to gleam and glisten until the blade morphed into a long katana which was slightly longer than Aizens arm, the swords hilt was in the shape of a dragon and its long super sharp one sided edge had ridges on the back where the non lethal side was. Unlike the black sword this sword only radiated power "It feels like the sun-no something far more powerful than the sun is inside that sword he's only an F rank though so his weapon can be that powerful," however all of his doubts were cleared when his green everfire was extinguished with just one swing of the sword. Darren had only felt fear about five times in his life one was when he fought and lost against an X class the second was when he saw the full power of an Overgod the rest were simply phobias or experiences in his childhood. But this time, this time he felt fear that was unlike any other, this time he knew he wouldn't make it out alive.
Darren drew out his weapon a wooden stick that was high in combat power and durability it was also enhanced with zen to make it slightly more durable than titanium itself. However Aizen simply swung the sword in his direction and his weapon shattered into tiny little pieces. "That's crazy! My weapon wasn't just destroyed it was shredded down to the last atom! Whatever that weapon the rules of physics don't apply to it. All the energy my weapon contained was absorbed into his aura," he panicked as all these thoughts ran through his head. He decided to run away as quickly as possible he jumped as high as he could to escape quickly. Then he felt it,it was as though ten tons of steel had hit him, he was pushed straight into the ground it should have killed him but it didn't he then realised how foolish he had been, the difference between the two individuals was like a grain of sand and a galaxy. He would die if this individual so much as thought of it.
"Y'know I tried to avoid this, I really did but I decided the simplest thing to do would just be to kill you, what a pity,"Aizen smirked as he hovered in the air.
Just as Darren was about to get up a bolt of lightning came crashing down on him and his whole body became wracked with pain. He tried again but this time his legs were blown off with pure physical force. For the final time he tried to get up but this time two spikes of metal erupted from the earth and severed his arms.
"I have to commend your spirit and bravery but unfortunately you have to die, I only wish I didn't have to be so cruel, if you so much as try to raise your head again the next attack will be far worse than the others," Aizen warned.
"I can't figure out what his power is at all! Whatever it is it's far beyond my comprehension, and his zen it dwarfs the zen even an SS class has,"Darren thought to himself as he accepted that he was about to die.
"Well then any last words?" Aizen asked Darren as he looked down on him from the sky.
"Karmas a bitch"Darren said as he made peace with himself.
Then Aizen swung his sword and Darren's head went rolling on the ground.
"What a waste"Aizen said as he teleported back to his apartment.
