Sara Shirato has dedicated herself to taking care of her younger sister Yura since she was a child. Nonetheless, with a desire for autonomy, Yura has become an obstacle in Sara's life. Yura's insistence on attending the same high school as Sara becomes the culmination point, prompting Sara to ask her recently acquired LRIG, Mihiro, for the independence she craves from her sister.
