Lawyer Kenji Shirato (Yuto Isomura) has a unique perception. Because he is different from the people around him and has an independent personality, he cannot adapt to collective activities and has dropped out of school.Today, he works in a small law firm and under the instructions of his benefactor and director, Kaori Kurujima (Ichikawa Shikako), is sent to a private high school as a school lawyer to deal with legal issues and provide legal advice and guidance to the school.

However, the “ Hamasola High School, which was chaired by Oi Misao (Goro Inagaki), is a merger of the boys' school, Hamaura Industrial High School, and the girls' school, Hama Yuri Women's College, and various problems continue to occur on campus.Especially the design of the new uniform, because it tries to reflect the concept of gender indiscrimination, the evaluation is extremely poor, and some students even refuse to wear it.

Against this background, it has become unprecedented for third-grade student union president Ryono Takano (Hi Takayuki) and vice president Miho Saito (Nan Keenna) to skip class together.Due to unknown reasons, Jianzhi was asked by the school to provide solutions, but Jianzhi himself was not good at the school's legal issues. Although he made legal suggestions, he could never find a breakthrough in the problem.

Jujujutsu Koda (Mayu Horita), a Mandarin teacher, has always cared for and protected him as a supporter of Kenji.Over time, students began to speculate that the reason why the two students missed classes might be due to changes in school rules after the merger, and some students even decided to abolish the uniforms by prosecution.In this case, Kenji proposed a moot court - ” uniformed referee.
