Mayu, better known by her ghoul alias Nutcracker, operated as a predator with a distinctly brutal hunting method—she'd incapacitate male targets by crushing their testicles before feeding on them. She worked for an underground "Gourmet" society, tasked with kidnapping humans for their purposes.
The investigation into her crimes fell primarily to the Suzuya squad, with the Quinx Squad brought in to assist. The case marked a notable operation in the CCG's efforts against the Gourmet organization.
