Bleach Fan-fiction 6

Kurotsuchi was interested. The mystery of the young girls mesmerized him and he worked day and night to solve it. The age of the girls and their capability to contain Spirit Energy did not match the amount of pure Spirit Energy  that was flowing out of their bodies. Another strange thing was the undercurrent of a slightly different Spirit Energy that was almost completely masked by the greater, stronger, Spirit Energy that ran from their bodies. This other Spirit Energy seemed to fit them better and if Kurotsuchi was not wrong, and he rarely was, it seemed like someone had given the girls it's Spirit Energy added to their own.

"This is very strange," he said.
"Yes Sir Mayuri," Nemu, his assistant said.

"I will figure this out," he said.

"Yes Sir Mayuri," Nemu said.

Soi Fon waited for the girls to return but they never did.
"What did I say? Was it something about going into the city?" Soi Fon frowned, deep in thought. 

"Hey, Captain, what do we do now?" Oomaeda, her useless Lieutenant said. 

"We keep waiting," she replied, "I'm going back to my rooms. If the Spirit Energy is sensed again, call me."

"Yes, ma'am," he said as she vanished into thin air. 

"What is it that you wish to report, Captain Kurotsuchi?" Captain Commander Yamamotot asked.

"I analyzed the Spirit Energy of the girls and I figured out what was bothering me about it. The energy was too condensed and jumpy. It was because this Spirit Energy is not their own. I discovered another, more stable and suitable Spirit Energy running under the larger one, which is the one that Captain Soi Fon felt. This Spirit Energy belongs to them. The other Spirit Energy belongs to someone else," he reported.

"Do we know who?" Captain Ukitake asked. 

"No, but this is where things get interesting," Kurotsuchi's eyes brightened as he started to describe what he had discovered almost by accident. "I decided to search to see if we had any matched for the stronger Spirit Energy on its own. I did not think that the search would lead me anywhere but I decided to try anyway. What I discovered is that we have records of a very similar Spirit Energy dating back 1000 years, found on a battlefield just on the outskirts of the village of Rukongai. It was the place where the Captain of the 2nd Squad at the time disappeared. Her name was Shihouin Aya."

Everyone's eyes widened at the news but none was more dramatic than the sputtered, "Aya?" that slipped through the Captain Commander's lips. Everyone looked at him in surprise as he usually was a very composed man and this was the first time that anyone had caught him by surprise. 

"Sir, do you know her," Captain Ukitake asked.
"Yes, she was Captain at the time that I became Captain Commander. She disappeared soon after my inauguration." 

Everyone watched him as he mumbled under his breath. 

"Find out more about these girls and see if you can get them to come here. I don't want to force them or they may not help but get them into the city," he commanded.
"About that sir," Soi Fon said, "A couple days ago I was able to speak to them briefly, as you know, but they vanished as soon as I mentioned getting them into the city. I feel that it could be that they are afraid of the city or something. I will keep on trying but also since I mentioned it. They have not returned to the same place." 

The Captain Commander sighed and everyone watched him with wary eyes. 

"Keep searching. Find that girl at all costs. We need to see if she has some sort of connection with the disappearance of Shihouin Aya."

"YES, SIR!" all the captains said.
