ローザ

In her early twenties. An elite new prison guard. She has a strong sense of justice and is very serious. She seems to do everything coolly, but she makes up for it with hard work. For better or worse, she is naive and believes in what she thinks is right.

If she works in the field for a couple of years in this prison, she is guaranteed to move on to a higher career. She thinks of her work in the prison as a step in the right direction, and tries her best not to make any mistakes. Therefore, she takes a cool and mature attitude to avoid getting involved with others, but at heart she is just a normal girl.
