Nnoitra turned around and grasped Aizen's waist, throwing him forcefully to the side, and stood up quickly before he could sink the dagger into his back. The knife clanged against the floor milliseconds after he moved out of the way. Aizen smiled gently at them as he got to his feet as well.
"It wasn't very nice of you to kill my brother," Aizen said as he took a step forward. "I was actually quite fond of him."
"Well he obviously found me more interesting than you," Nnoitra snapped. "What kind of sick fuck messes around with his brother?"
"Me," Aizen said simply.
He lunged at Nnoitra. Nnoitra scoffed and grasped Aizen's wrist. "You think you can beat me dumbass?"
"Oh Nnoitra, I knew you'd say that," Aizen answered shaking his head. "That is your down fall. You're just too confident in your own abilities."
Aizen jumped, brought his knee up, and connected it with Nnoitra's stomach. Nnoitra doubled over as pain laced through his abdomen. Aizen grasped his right arm and gracefully moved behind him, locking it behind his back. He brought his hand down on the back of Nnoitra neck hard. Nnoitra fell on his stomach and Aizen kept his arm securely behind him, mouth hovering next to his ear.
"That's it?" Aizen questioned. "It's a shame Tesla was too blinded by his love for you. If he hadn't been, he would have killed you easily. I knew this would happen and that was the reason I tried to keep Tesla from releasing you. I was already aware of your intentions although I was not aware that he would turn on me so quickly."
"Get the fuck off me!" Nnoitra yelled.
"Very well," Aizen answered chuckling. As soon as Aizen released him, he was back on his feet. Aizen tossed him the dagger. "Let's see what you're made of."
"You just made the mistake that will cost you your life!"
He thrust the dagger at Aizen, but he swiftly moved to the right, evading the attack. He grabbed the arm that had the knife, pulled him down forcefully, and kneed him in the face twice. Aizen once again twisted his arm behind his back and knocked him back down onto the unforgiven concrete.
Aizen took the dagger away. "I must say this is fun. I'll wait a while before killing you two."
He stood up again allowing Nnoitra to get to his feet. He moved to clothes line Aizen to the ground, but Aizen lowered his stance causing Nnoitra to barrel over him. He flipped him on his back. As soon as he hit the ground, Aizen stabbed him in the stomach right next to the wound his deceased brother had caused.
"Nnoitra!" Nell screamed.
"It is no use my dear," Aizen said smiling gently at her. "Your little boyfriend is no match for me."
Damn it, Nnoitra thought as he struggled to pick himself off the floor. I didn't know this fag was a master of martial arts. This makes things a lot harder.
"Are you ready to try again Nnoitra?" Aizen taunted gently.
"Fuck you," Nnoitra spat.
He brought his right leg up to kick him and Aizen caught it. While holding the dagger in the other hand, he placed it on Nnoitra's side and used his weight to knock him off balance. He came crashing to the floor again. Aizen stabbed him in the arm and dragged the knife down to his elbow.
"You just aren't very good at this are you Nnoitra?" Aizen asked as he hovered over him. "Perhaps I will kill you with my bare hands. It seems only fair."
Aizen tossed the knife over his shoulder and grasped Nnoitra by his hair. "This may be a little painful. I do not care for vengeance, but it is only right that I avenge my brother."
