Gouriki revealed that like her character Kotone, she has a lot of strength since she was a child and fought with boys when she was in primary school. There was also a time when she got into constant arguments with her mother but they are very close now so she wondered why she had been that rebellious then. Hashimoto chipped in to say that she had seen Gouriki's action scenes up close so she wanted to get a stand-in for her clashes with Gouriki because she didn't think that she would stand a chance against the latter.
Adachi who plays a prisoner caught for repeated dine-and-dash crimes, joked that people may think that she is still poor after all these years to resort to such crimes because she was known for playing a poor girl in her signature work "Ienakiko" when she was a child actor. On the other hand, Triendl who had to learn how to speak crudely like a gangster, bought the manga "Bukkomi no Taku" as preparation for the filming. Meanwhile, Hashimoto who usually played sexy characters in dramas, said that she would conceal her sexiness in this drama but her co-stars protested that she was still sexy even in the prisoner's uniform which covered most of her body.
