Seishirou Jigoku was the Meiji period Japanese judge who presided over Ryūnosuke Naruhodō's trial for the murder of John Watson and Haori Murasame's trial for the murder of Jezail Brett.

Forced to commit murder Edit

Main article: The Professor Killings

In the year 1890, exchange student Genshin Asōgi found out that serial killer Klimt van Zieks (also known as the "Professor") was being blackmailed by Hart Vortex. After this, Vortex pinned the "Professor"'s murders on Asōgi, ultimately resulting in Asōgi being tried and found guilty of the murders. Asōgi was subsequently given the death sentence. However, he was alive when buried. When Vortex saw someone witness Asōgi rising from the latter's grave, Vortex forced Jigoku to kill Asōgi.

Career Edit

Trial of a university studentEdit

Main article: The Adventure of the Great Departure

Seishirou Jigoku presided over the trial of Ryūnosuke Naruhodō when he was accused of murdering university professor John Watson. Although Kazuma Asōgi was originally going to act as the defense attorney for the case, Naruhodō opted to defend himself against prosecutor Taketsuchi Auchi. Ultimately, Watson's actual killer was revealed to be an exchange student named Jezail Brett. Jigoku subsequently acquitted Naruhodō.

Jigoku had initially sent Kazuma Asōgi to murder Tobias Gregson as part of a greater plot to cut all loose ends regarding his murder ten years ago. However, when the lawyer seemingly died, Jigoku felt he had no choice but to visit the country himself to handle Gregson.

Trial for Brett's murderEdit

Main article: The Adventure of the Blossoming Attorney

About nine months later, Seishirou Jigoku presided over a similar case, where Brett was murdered and university student Haori Murasame was accused of the crime. Auchi also acted as the prosecutor for this case, and Murasame's defense attorney was her friend Susato Mikotoba; a judicial assistant disguised as "Ryūtarō Naruhodō". The actual killer of this case was eventually revealed to be journalist Heita Mamemomi, and Murasame was subsequently acquitted. Jigoku later appears to throw Mamemomi to the baliff before the journalist could say anything about Asōgi. After formally intoducing himself to Susato, he reveals he knew that she pretended to be a male attorney then leaves to discuss something with Yūjin.

Murdering a legendary detective Edit

Main articles: Twisted Karma and His Last Bow and The Resolve of Naruhodō Ryūnosuke

Tobias Gregson was given a “Death Bringer” mission for 10/31, aboard the Balabrock as it head for France. The target was Seishirou Jigoku, and in a twist of fate, the assassin sent with him was Asōgi. When Jigoku returned to his room, he found Gregson there. He body slammed Gregson, knocking him unconscious, but as first class cabins are surrounded by guards, he decided to wait until the emergency drill later that evening to do the final deed. Unfortunately, just as that time arrived, Gregson woke up and started attacking Jigoku in a frenzy. In a moment of panic, Jigoku used the gun the English government had given him in his exchange program sixteen years ago and shot Gregson.

He took Gregson’s coat off and hid his body in the freezer, trying to buy some time and fake Gregson’s time of death. He then put Gregson’s body in his own suitcase and took him off the boat and to the hotel, as there was no chance to throw the body overboard due to all the guards.

He had heard about Gregson’s secret room with Everyday Mittlemont from Vortex, and went to drop the body off there. He set up some firecrackers he bought from Venus and used the candles as a makeshift timer that would go off when the body warmed up. That way, when Mittlemont came to visit, he could be framed. Unfortunately, Barok van Zieks showed up on his investigation of Tobias Gregson and he took the fall instead.

It was only in the subsequent trial that Seishirou Jigoku was finally brought to justice for his crimes and arrested.


Seishirou Jigoku has a neutral personality, befitting of a judge. He regretted killing Genshin Asōgi and allowed Susato Mikotoba to act as defense despite women not being allowed to practice the law. However, he is willing to go along with Hart Vortex's plan in exchange for being the Minister of Foreign Affairs.

He is also strong enough to be able to smash the entire witness stand.

Name Edit

  • Jigoku, when written as 地獄, means “hell”.
