Set in the Tokyo District Court, the story follows Soma Aoi, a liberal-minded judge who struggles to fit into the conservative judicial system.
The judicial community centered around the Tokyo District Court appears to be a quiet, rational group of experts on the surface. However, beneath that exterior lies a unique dynamic shaped by hierarchies—Presiding Judges, Right Associate Judges, and Left Associate Judges—as well as graduation years, assigned locations, experience in judicial administration, and personnel evaluations by the Supreme Court General Secretariat. While judges are legally independent in their judgment, they are consciously or unconsciously aware of factors such as whether their decisions will be upheld by higher courts, consistency with Supreme Court precedents, the views of their Presiding Judge, and how it all affects their future career path. A Presiding Judge is not just the head of the court; they handle case management within the division, mentor junior judges, and coordinate judicial administration. The Right Associate is an experienced mid-career judge who acts as a mentor to the Left Associate. The Left Associate, usually an Assistant Judge, handles much of the drafting for collegiate bench rulings, learning the methodology of judicial judgment through experience. While the three judges are theoretically equal in a collegiate bench, the Left Associate often carries the heavy lifting. Decisions are made by majority vote. While disagreements are not uncommon, they must ultimately be reconciled into a single judgment. Outside the courtroom, judges are ordinary members of society. They go out drinking with classmates from the Legal Training and Research Institute, celebrate juniors' weddings, gossip about personnel transfers, and complain about life in government housing. On the other hand, they never speak lightly about their assigned cases to outsiders. For a judge, transfers dictate their entire life. While prestigious divisions in the Tokyo District Court, the Supreme Court General Secretariat, or High Court service are highly valued for career advancement, there are varying degrees of enthusiasm for Family Court or regional assignments. While the Divorce Division of the Tokyo Family Court involves sophisticated work dealing directly with human relationships and emotions, it is sometimes viewed as a career setback by judges aspiring to the elite civil divisions of the Tokyo District Court. While the Supreme Court General Secretariat does not directly order conclusions on individual cases, it holds strong influence over a judge's career through assignments, administrative posts, and evaluations, making its presence felt by most judges. Soma Aoi has an economic foundation through Aoi Real Estate and does not depend on a judge's salary or promotions. Consequently, he has less fear regarding personnel matters than other judges. This is a source of Soma's freedom, and simultaneously the reason he is considered difficult to handle by the Supreme Court General Secretariat. In this world, "the atmosphere," "graduation class," "evaluations," and "who knows whom" are more important than explicit factions. Judges are part of the state power, yet they also hold the role of restraining that very power.
Assistant Judge at the Tokyo District Court (also serving at the Tokyo Family Court Divorce Division). Left Associate. A "Kiryo-jin" since elementary school at Kiryo University. He exudes high breeding and intelligence but is not stiff. He has refined looks and is social, naturally becoming the center of any circle. He attends drinking parties and mixers. He refuses to live in government housing, enjoying life in a luxury apartment instead. He handles warrant duty and presides over divorce mediations. In criminal proceedings, he is strict with the prosecution and holds the view that emergency arrests are unconstitutional, often rejecting warrant requests. He takes pride in leaning toward a liberal legal framework that emphasizes human rights. He clashes with Presiding Judge Reiko Kashiwagi over constitutional judgments regarding same-sex marriage; while Kashiwagi favors judicial restraint, Soma believes "the court must not run away from constitutional judgment." He struggles with his brother-like relationship with Yuta Hiyama. Yuta values Soma's ability but worries his overly free nature won't fit the judicial organization. In his private life, he is gay. He likes Yuta but enjoys dates with pilots he meets on apps. He feels frustrated by Yuta's attitude. Yuta also has feelings for Soma. He is not out within the court. Being gay is a vital part of Soma, but it doesn't define him entirely. His pride as a judge, his identity as a Kiryo-jin, his pride as a scholar publishing papers, his freedom as a wealthy man, friendship, romance, sexual relationships, and how much he can remain himself within the judicial organization—that is Soma. In the Family Court, he is popular with mediation committee members and clerks, but he dislikes the self-important attitude of the Family Court probation officers.
