During the Second Fight between Ichigo and Ulquiorra
"You cannot defeat me, Kurosaki. You couldn't beat Nnoitra and he was trash, give up," Ulquiorra said calmly.
"I'll never give up! I'll defeat you, then I'll defeat Aizen!" Ichigo yelled as he rushed at Ulquiorra.
Meanwhile...
Aizen, Gin, and Tousen were trapped in the fire prison watching the Shinigami and Arrancar fight. Tousen and Gin both turned and looked at each other, then Tousen shouted, "Operation Justice has begun!" Halibel stopped fighting and started going toward the fire prison.
Many Years Earlier
Light could not go to heaven or hell because he had used the Death Note, instead he became a soul parasite. He was forced to temporarily take over other souls and feed off them until they died. If only I could find a body that didn't fight back, then it wouldn't die as quickly... Light thought. This shouldn't be happening to me! I should have been a god! I deserve better than this! He thought angrily. At first he took over human souls then he grew a little stronger and he was able to take over weak hollows. One day he followed another hollow into Hueco Mundo. He discovered he was much stronger there and was able to take over more powerful hollows, but he still wanted to find a more permanent body. One day he discovered Las Noches. He explored it and was surprised by how many powerful people he found in it. He stayed there listening and watching. Soon he learned what Aizen's plans were and other important information. I must have Aizen's body! But how can I take it? He is way too powerful... there has to be a way... Light thought. One day he saw Aizen create an Arrancar. That's it! I can take an Arrancar over while it's being made! It will be too weak to fight back and I can completely crush it! Now I just have to wait for him to create a new one... Then came the day a new Arrancar was to be made. Aizen used the Hogyoku to transform it.
"What is your name, new bother of ours?" He asked.
Light searched its memories and found the answer. "Wonderweiss, Wonderweiss Margera," he answered. He decided he should act stupid because when he searched its memories he found that it was very retarded so he would just act like it would. First I need to convert some of Aizen's followers to my side. Who should I start with? Ahh yes, I'll start with Tousen Light thought. He began following him around, learning more about him until one day... "Tousen, do you believe in justice?" Light asked.
"I believe in justice and I will always follow the path with the least bloodshed. Why do you ask?" Tousen asked. Then Light told him his plans.
"Will you follow me?" Light asked.
"Yes, I believe you have a pure heart, I will serve you," Tousen answered. So it began. Light converted Gin and Halibel over time. Then he plotted with them.
The Day of the Invasion of Karakura Town
"So here's the plan, I'll try to take over Aizen when his guard is down then you guys give me some of your power to help. Also, Tousen, I need to hang out in your body for a little while. It will be called Operation Justice," Light said.
"Okay," Gin, Halibel, and Tousen said.
Operation Justice (Where we left off near the beginning)
"What's going on?" Aizen asked calmly as Tousin stepped toward him.
"Sorry but I must betray you, I have found a new and more just leader," Tousen replied. Light came out and entered Aizen's body. He was fighting hard to stay in. Tousen, Gin, and Halibel started feeding him their power.
I can do this, I will be god! Light thought. After a while of struggling he managed to take him over. "I've won! If you wish to live then serve me! Your old master can not save you!" Light shouted at Stark and Barragan.
"Aww man, more trouble... I guess I don't have a choice," Stark whined.
"I will serve you..." Barragan grumbled.
"Let us return to Hueco Mundo," Light said. Then he easily broke out of the fire prison.
Meanwhile...
Ulquiorra and Ichigo were still fighting when Light and the others came back. "You can go back now, Ichigo. Your fight was with Aizen, not me," Light said.
"Who are you?" Ichigo asked.
"Just call me Kira," Light answered. As Light said this something within Ulquiorra stirred.
Light Yagami? L thought.
