One morning, Sakisaka Kento, a high-flyer and partner of the law firm, Jinguji, is using the time before work to scour a stylish fashion boutique to choose a present for the president of a company where he serves as legal adviser. At that moment, a rookie lawyer Atami Yusaku assumes a post at Jinguji. He is told about the lawyer who will be his mentor by the boss Jinguji Kazuhiko. Besides Sakisaka, there are the partners Natsume Yoshie and Nekota Junichi; their respective associate lawyers Akahoshi Gen and Jonouchi Mari; and the paralegal Tsukumo Osamu. Atami will learn the ropes as a lawyer under Sakisaka, but Sakisaka seems displeased in some way. He gets a request to defend Shigekuni Yuko, the company president of Mami Design, in a copyright infringement lawsuit. She was commissioned by Teito Advertising, the largest advertising agency, to create a character design for a soft drink. But the design was rejected because it did not suit the sponsor’s image. Several months later, she had just used that design for a character in a separate town renewal event project, Teito Advertising sued her for copyright infringement. Shigekuni talks about their demand for 100 million yen in compensation. There is an official purchase order between the two companies and it contains the clause “Assign the copyrights for the character design to Teito Advertising”. Despite the overwhelmingly unfavourable circumstances, the attitude of the legal adviser of Misaki and McKinley, which is Teito Advertising’s attorney, makes Sakisaka declare a full scale battle to Jinguji, “Mami Design won’t have to pay a cent!” Jinguji who treats Misaki and McKinley as an enemy, instructs Yoshie and Nekota to support Sakisaka and orders them to win this all-out fight. Yoshie and Nekota glance through the complaint from Teito Advertising and unanimously pronounce that he has no chance of winning. Nekota abandons Sakisaka. In response, Yoshie indicates that she will continue. However, after she hears about the that he has been secretly formulating a counterplan, she finds herself at a loss for words at the reckless plan … … Sakisaki is regarded as the ace of the law firm, but his only weak point is a lawyer at the same firm who also happens to be his ex-wife Natsume Yoshie. He has been raising their daughter Mizuki as a single father since their divorce. A stylish lawyer who holds her head high, Yoshie is down-to-earth and a perfectionist. These two rival lawyers often have well-reasoned legal arguments regarding the cases of their clients. However, when they wander off topic, they will call each other “papa” and “mama” the moment they lose their cool and start quarreling like a couple.
