Random and first Kill la Kill oneshot!

Part of the reason Satsuki felt so strongly about avenging the sister she never knew was because, at one point, she was merely a little girl. And she did what all little girls did went presented with something they couldn't have.

She daydreamed of if she could.

Being raised an only child made one wonder what it would be like to have a sibling. In her early days before she became the woman she was today, she often fantasized of the little sister she thought she could never have.

She named her sister Sakura.

It was a common name, but a pretty one, and it sounded pretty with Kiyruin attached.

Sakura Kiyruin.

She never thought it would later turn out to be Ryuko Matoi.

She wondered what she would be like, cute and sweet like their father, or cool and proud like their mother?

Ryuko was cute and proud, but not sweet or cool.

She imagined Sakura with grayish white hair like their mother's. She could even see the plethora of a rainbow coloring the underside of it as they played.

Later on it would be blue like their father's, wild and unkempt with no hint of her mother's hair color tainting it.

Ryuko's was black with a red streak in it, a result of the inhuman experiment performed on her.

She often imagined her wearing the color pink for some reason. Perhaps it was an unintentional influence of the name she had chosen, but Sakura Kiryuin rarely wore a color other than pink.

She was fairly certain Ryuko would try to kill her if she ever attempted to make the younger wear anything pink. And quite frankly she really couldn't blame her.

Sometimes she had to wonder if she'd be stronger if Sakura had survived, if she'd have the strength to protect her sister from their mother and her torment.

Ryuko didn't need to be protected.

As Satsuki grew up, and the more she daydreamed of the sister she never had, in those moments where she was unbearably bored, or desperately needed a distraction, she dreamed and dreamed. And the more she thought about it, the bitterer she became.

Being denied both her father and her unborn sister, left alone to fight against this creature that passed itself off as a woman, as a mother, made her very, very angry.

Words couldn't describe the shock she felt when her mother revealed the truth, that Ryuko, brash, stubborn, loudmouthed, ill-mannered, pigheaded, and cocky as all Hell Ryuko Matoi…was the Sakura Kiyruin she had daydreamed about.

It is often said that when you imagine for something for so long, eventually you can't help but be disappointed with the real life thing.

Ryuko Matoi was nothing like the Sakura Kiyruin Satsuki had imagined.

But, in the end, Satsuki would have it no other way.
