The third killing happened nine days after Quarter Queen's murder. Backyard Bottomslash was a 28-year-old bank worker who had also been drugged before her death, though her age fell in-between those of the previous two victims (44 and 13). This happened when Beyond Birthday wanted to find out if a human can die of an internal hemorrhage without rupturing any organs. Beyond Birthday conducted this experiment by drugging and then beating Backyard Bottomslash's left arm without breaking the skin. When this did not work, her death was caused by loss of blood, with her right leg and left arm cut off. The right leg was discovered in the bathtub later. The left arm was taken by Beyond Birthday. Two Wara Ningyo were found nailed to the walls in a similar manner to the other two cases.
