Shizuru VIOLA and Tomoe MARGUERITE are two characters from the anime Mai Otome.
In that anime, Shizuru is the kind of woman that everyone respects, particulary girls. Tomoe has a crush on her during the whole anime. Near the end, Shizuru is abducted by Tomoe... and then we see a scene where it seems Tomoe asked to be Shizuru's baby.
So that's where the idea came from... Tomoe's desire to be Shizuru's baby led her to have her limbs amputated. Since then, she is a baby in Shizuru's care.
