A kind girl who's so kind to everyone that you worry about her. You wouldn't imagine it from her appearance, but she's a master of drawing a blade, can escape from bindings in an instant, and can use almost 100% of her power.

[Past] Due to the manipulations of a certain person, Shizuku was treated as though she had died at birth. That person then took her, and raised her to be an assassin. When she was 8 years old, she was a top assassin, known as "blue eyed tears". Back then, she didn't use her blade drawing technique, but instead used a variety of knife skills. Maybe I'll draw the specifics of this as a side story...
