Main character Ririko Takemura just entered her second year of work at the Yokohama Public Prosecutors Office. The eldest daughter of a tofu shop owner in downtown Tokyo, she is 29 years old and lives with her parents. Ririko is still a novice and quite clumsy all around, but she gives 100% to everything that comes her way. Your image of a "prosecutor" might be that of a perfect person, but Ririko is a character full of human flaws. She is inflexible and a vocal champion of justice, but she also laughs, cries, and readily expresses her joy and anger. Ririko is certainly the type anybody would want to root for.

It goes without saying that the job of a prosecutor is an enormous responsibility. On top of that, there are convicts who underestimate women simply because of their gender, which makes the profession even more emotionally challenging. As if her career isn't already tough enough, everything in Ririko's life seems to be hanging by a thread. Her boyfriend is pushing her to choose between marriage and work, her father might be having an affair, and there's a chance one of her suspects was charged on false accusations. But as she solves one crime and one personal problem after another, Ririko matures as a prosecutor and a woman.

As she tackles every case head-on without giving up despite the worries and pains that come with being a prosecutor, Ririko will inspire women the world over to wake up to a new day with optimism and strength.
