The protagonist Ryoko Kaminami lost her mother at a young age and was dependent on her father. With her outstanding talents and the knowledge accumulated from attending trials, she passed the judicial examination in high school in one try.However, after her father suddenly disappeared, she did not pursue the truth or enter the legal profession, but lived alone.

Until 2024, he decided to become a lawyer by chance, and took winning the case as a matter of course.In order to win the case, she did whatever it took to expose the truth that was difficult for the other party to face, and she also put forward her own unique insights into social issues such as sexual harassment, appearance discrimination, and reproductive medical care.                                                   

Ryoko Kaminami (Quori) suddenly appeared at Keiko Ohkusa Law Firm, where Keiko Ohkusa (YOU) is the director, and claimed that I decided to become a lawyer.She has neither the clothes nor the appearance of a lawyer, and even her true nature is elusive. She just keeps shaking her lawyer badge, which puzzles Sugiura Yoshihiro (Jesse), a young lawyer who graduated from the Tokyo University School of Law.He already knew that Ryoko would come, so he readily accepted her.

Furthermore, Ryoko offers to defend Shioya Ryo (Hagiwara Rihisa), who is suspected of abetting suicide, which Sugiura originally planned to reject.Ryo Shioya knew that his date, Kawano Sae (Fujiyoshi Karuzu), had attempted suicide, but he still sent a “go to hell text message.Moreover, Kawano Sae's mental state is usually unstable, and she often goes to the psychological counselor Umemoto Asami (Minami) for treatment.Since cases of abetting suicide are rare, Sugiura thought it was too forced for a newcomer, but on the contrary, he was ordered by Ohkusa to support Ryoko.

During the meeting, Shioya described himself as haggard and continued to express his apologies to the late Sae, emphasizing that he never wanted her to die, but that he wanted to die.In fact, the text messages exchanged between the two people on the eve of their death started from Shioya's text message "I want to disappear”".

Ryoko went to the home of Sae's boss Kameoka and her biological parents to understand the situation. Of course, they could not listen to Ryoko, who was the defendant's defender, so Ryoko took unexpected actions.
