Silent Rogue
Sakura Takahashi - "The Giantess"
Sakura is usually known by her classmates as "The Giantess", and it's not hard to see why. While she's still 14, she's also "cursed" with an overly tall stature, big hands and feet, and a deep voice, making her classmates fear her more than anything. Personality wise, she's very shy and socially awkward, and usually would like to disappear. She is also very kind, however, and does like to help out people in subtle ways, where they don't know that she helped.
Fleur Emmaline - "The Deadly Shadow"
In life, Fleur Emmaline was known as "The Deadly Shadow", for her tendency to let her influence be felt, but never letting herself be seen by the general populace. She lived in a war torn France, and spent her time silently assassinating nobles for her faction. That doesn't mean she couldn't fight directly, however, as seen when she was caught thanks to a person who she thought was her friend, and had to fight for her life. She ultimately died, but it was worth the effort. As for how she feels about the modern world, she's deeply curious about it, and often asks Sakura a lot of questions about it.
When fighting as one, Fleur Emmaline grants Sakura the standard mahou shojo abilities, as well as invisibility, super speed, and a shrinking ability, in order to get into small spaces more easily.
