The Kyorei Clan (共礼会, Kyorei-kai) is a yakuza group based out of Kyoto. They are featured as a secondary antagonistic group in Judgment.
The Kyorei Clan originally operated in Kansai but by 2018, on orders from their financial backer, real estate developer Shigeru Kajihira, they'd started expanding into Tokyo. Their expansion particularly focused on stealing territory from the Matsugane Family, one of the smaller Tojo Clan families that was less prepared to fight back.
This expansion served to protect Kajihira's latest land investment: Kajihira had been trying to buy out the land on which the Advanced Drug Development Center was located so that it could be redeveloped into a resort and commercial district. Before this happened, he first needed to have the ADDC shut down by the health ministry, so he bribed Health Minister Kazami and Vice Minister Kaoru Ichinose to ensure this. Kajihira also needed to ensure the Kyorei Clan controlled the territory surrounding the ADDC so that no other yakuza could force protection payments out of him when the land started being redeveloped.
However, trouble started befalling the Kyorei's plans. First, the closure of the ADDC stalled due to the development of a promising Alzheimer's drug, AD-9. Secondly, several of their members started being gruesomely murdered by what appeared to be a serial killer known to the public as "The Mole", whose calling card is gouging out the eyes of all his victims.

After a third Kyorei member; Toshiro Kume, is killed by the Mole, the police arrest Matsugane Captain Kyohei Hamura on suspicion of being the culprit. In response, the Matsugane Patriarch, Mitsugu Matsugane, hires the Genda Law Firm to defend Hamura and the Yagami Detective Agency to investigate the case. The detectives, Takayuki Yagami and Masaharu Kaito, end up coming into conflict with the Kyorei's lieutenant, Akira Murase, during their investigation, since he tries to sabotage Hamura's defense so he'll be convicted. Ultimately, however, Hamura is acquitted for the murder.
Yagami and Kaito decide to continue investigating the Mole's murders even after the court case is settled, so they wind up doing more digging into the Kyorei Clan and why they would be targeted by this serial killer. Their snooping eventually attracts the attention of the Kyorei Clan's Captain, Satoshi Shioya, who tries to kill them in retaliation for helping Hamura get off the hook. However, the duo are saved by their ally Fumiya Sugiura.
Kajihira eventually decides that the best way to deal with the meddlesome detectives would be to hire them to investigate the ADDC for him. In order to ensure their compliance, he orders Shioya to kidnap Yagami's former girlfriend, Prosecutor Mafuyu Fujii. Though the kidnapping attempt is foiled and the detectives severely thrashed Shioya and his goons in retaliation, Kajihira nonetheless manages to convince them to work for him: Yagami had determined beforehand that the Mole and the ADDC were connected, so investigating the latter could lead to the identity of the former.
As it turns out, the Mole was an assassin who worked for Captain Hamura and the pair of criminals had been hired by Dr. Yoji Shono and Vice Minister Ichinose of the ADDC to kidnap Kyorei Clan members to serve as human test subjects for the development of AD-9.
In order to learn the Mole's identity, Yagami, Kaito and Patriarch Matsugane kidnap Hamura and take him to the Kyorei's Kamurocho base, Cabaret Honmauren, to question him. The interrogation is interrupted when Hamura's goons raid the Kyorei base to rescue him. During the attack, Lieutenant Murase is killed with a bomb and Captain Shioya is kidnapped. Shioya would later turn up dead with his eyes gouged out on the streets of Kamurocho, having been used for another of Shono's human experiments.
When the conspiracy is eventually exposed and AD-9 is revealed to be a failure, the development of the drug is concluded and the ADDC is shut down. However, the exposure of Vice Minister Ichinose's corruption also leads to all his policies falling under review, so the Kyorei Clan will not be sold the land for redevelopment, meaning that they sunk 10 billion yen into the acquisition project and the expansion into Kamurocho for nothing.
