Plot
Sakurako Kujō is a genius beauty in her mid-twenties whose life is centered around one thing and one thing only: bones. With little tolerance for others, she would be completely isolated in her study full of skeletons if it weren’t for high school boy Shotaro—her new assistant and constant companion. Why exactly she has taken a shine to him remains a mystery, but one thing is clear: Whenever the two go out together, the chances are high that they will come across a human corpse.
