((What if Ryuko had been kidnapped by Ragyo? What if this forced Satsuki to abandon Plan A and place the academy in lockdown?))

One day, in the slums at the edge of Honnouji Academy, Mako cheerfully made her way to school. "Good morning, rock. Good morning, patch of dried grass. Good morning, sun."

And then the walls of Honnouji Academy rose to great heights, blocking out the sun. "No! Mr. Sun!"

And then a limo burst out of the ground and drove towards the school.

"So, Lady Satsuki managed to get in." Sanageyama let out the breath he was holding.

"Honnouji's defenses has been raised, and the tunnel will be sealed." Inumuta reported. "Still, for her to activate the Fortress protocol this early..."

The Elite Four saw the limo pull into the middle of the school. The butler Soroi stepped out of the driver's seat and headed for the passenger seat. Just as he opened it, Satsuki and one other girl flew out, with Satsuki in a strange yet saucy outfit. "Damn it, human! Give me back my Junketsu!"

"Lady Satsuki!" Gamagoori quickly restrained the girl with his whips, but much to his horror, the girl shifted her attention on him and then pulled back on the whips, causing him to fly over her head. Luckily, Gamagoori managed to land on his feet. "Shackle Regalia!"

Bandages made of uncuttable cloth lashed out and grabbed the girl, and this seems to restrain the girl for now. "Who are you to harm Lady Satsuki?"

"She's my sister." Satsuki said.

"I don't care if you are Lady Satsuki's sister, I will not let this go unpun-" The Elite Four blinked as one. "Wait, your sister?"

Sanageyama looked at the bound girl and Satsuki, who seemed to be stripping out of her strange outfit and into bathrobes Soroi provided for her. "I...honestly don't see the relation."

Nonon was the one who was most surprised. "Lady Satsuki, why didn't you tell us you had a sister?"

Satsuki Kiryuin looked around the mansion. Ragyo had called her to check on the progress of the Goku Uniform. After a small "chat", Ragyo had quickly departed for business. Still, Satsuki elected to stay at the mansion.

Of course, her reason was not to rest for the night but to map the mansion one more time. It seems, despite Satsuki living on her own, that Ragyo had not set up any traps here. At least she would not have to worry about any unexpected resistance. She then saw one more door and decided to check that as well.

That door was one she was familiar with. It held her wedding dress, a Kamui made entirely of Life Fibers. As she entered the almost empty room, she gazed upon the imperial robes. She thought giving clothes a name was ridiculous, but if she was a bit more innocent than she is now, she knew the perfect name. Sealed away from man's eyes, covered in plastic to ward off dust. The alien fabric as pure as-

Satsuki blinked and took a closer look. There was a strand of Life Fiber, no, red hair on the uniform. Then Satsuki turned and blocked a punch from an assailant. To her credit, Satsuki held her stance even as she was pushed back ten feet. She did not know who this assailant was, but she could assume, with that red lock in her black hair, that she touched Junketsu. "Who are you?"

The girl laughed. "Mom warned me you were anti-social. Then again, she did raise you as a spoiled princess."

"To think, my little sister was alive, only to be found and brainwashed by Ragyo." Satsuki lamented. She watched through a monitor as her sister tried to escape one of the Explosive Club's bomb bunkers. "Years of planning, and I gave it up to pull out a sister whose name I nevered learned until now. Worse, I brought in a threat that could bring down Honnouji from the inside. Ironically, it's the same Kamui I meant to wear."

Satsuki looked down at her recently named Junketsu. If she had not put on Junketsu, she wouldn't have been able to subdue her sister let alone walk away. Unfortunately, her sister "owned" Junketsu, and Satsuki had to surpress the idea of how strong her sister could actually become. "Ryuko Matoi, that was the name she grew up with."

Inumuta placed his data on the big monitor. "Ryuko seems to be worse that Sanageyama, though I don't have much information on her. However, her father, Isshin Matoi, did work in REVOCS until his disappearance, and a lot of his money seems to be disappearing into Osaka."

"No doubt to find out what Ragyo was up to." Satsuki knew that Ragyo would probably try to keep all information on Life Fibers a secret, yet the way Ryuko spoke of her father and still recognized her mother seemed off.

"Inumuta, can you find out where they lived? I don't think Matoi only hid my sister."
