Nutcracker was a sadistic ghoul, and took pleasure in torturing her male victims, crushing and eating their genitals. She also had an obsession with money and beauty, stemming from her upbringing in extreme poverty.
The Quinx learned Nutcracker was seeking targets in the 13th ward, for an upcoming auction. Based on the requested items, she was looking for young women at local nightclubs and the Quinx go undercover in order to bait her. They observed her speaking to young women at the club, offering them a part-time job. An intoxicated Mutsuki approached her brazenly, and managed to secure the information about the \"job,\" providing information on the date of the Auction. A plan was put into motion to use Nutcracker to infiltrate the event, tricking her into bringing an undercover ghoul investigator to the location.
On the day of the Auction, Nutcracker met with Mutsuki and Juuzou Suzuya and drove them to the location in a luxury car. However, the vehicle was filled with gas and both were knocked unconscious. Some time later, Nutcracker fetched Mutsuki and dragged him onto stage to be sold. The revelation that the \"surprise item\" was a one-eyed ghoul caused a frenzy and the resulting bidding war fetched a record 200 million Yen. After the sale, Nutcracker took Mutsuki back to the holding area and was so excited that she kissed him on the cheek in celebration.
The incident with Nutcracker haunted Shirazu, as he realized he was essentially given a weapon made from someone human-like that he had killed. This relationship resembled the opposite of Kaneki and Rize, where instead of becoming a coping mechanism, Nutcracker served as a trauma which reminded Shirazu of his feelings of guilt and doubts regarding the nature of ghouls. 1e1e36bf2d
