The 12 Constellations Art Gallery houses the works of the famous French sculptor Paul Holic. It is in fact a mansion previously owned by Issei Tenkai, but it was repossessed from him after his arrest for being an accomplice to murder. However, in 2019, Tsukasa Oyashiki purchased the mansion and refashioned it into a museum dedicated to Paul Holic.


IS-7 IncidentEdit

Main article: IS-7 Incident

In 2001, renowned pastry chef Issei Tenkai hosted a grand cookery competition in his mansion. The grand prize of the contest was a "recipe book" which was actually a list of advanced experimental drug recipes not available to the general public. Tenkai had come to obtain it due to his close ties to the Tenkai Group, a pharmaceutical institution which he was set to inherit. The Group had objected to Tenkai's giving away the book, but he had not been swayed and had carried on with the contest. However, the Group sent Delicy Scone, an elite pharmacist and member, to compete in the contest and retrieve the book in a way that would please Tenkai.

Among other notable competitors were Yutaka Kazami and Isaku Hyōdō (who was actually a famed French sculptor by the name of Paul Holic). Kazami nursed an extreme desire to become the world's greatest pastry chef, but he also suffered from a disorder that caused a complete lack of ability to taste. His reason for wanting the book was that it contained a recipe for a drug that could temporarily cure his illness. Holic, however, was in financial trouble and wished to sell the "recipe book" to one of the Tenkai Group's rivals for a lot of money. However, neither could win the contest on their own; through extreme training, Kazami had become excellent at producing superb-tasting foods, but he was severely lacking in aesthetic sense. Holic, being a sculptor, was naturally very good at design, but completely unable to produce something of good taste. As a result of this, the two agreed to collaborate; Kazami would do all the actual cooking and baking, while Holic would do the design. Using this method, the pair were able to make it to the semifinals, along with Delicy Scone. However, in the finals, Holic ended their collaboration just after Kazami had given him two batches of sherbet to sculpt, thus giving Holic everything he needed but leaving Kazami with nothing but his own ingredients and terrible design skill. Holic then anticipated that the desperate Kazami would try to "steal" the prize by taking photos of the recipe, and caught him red handed in Tenkai's room doing just that. Holic then started to blackmail Kazami by threatening to expose him as a thief, even going so far as to deal Kazami a blow using a rock salt lamp that was in the room, in order to prove his superiority. Kazami, blind with rage, responded by killing Holic using the other salt lamp.

Kazami quickly devised a plan to give himself an alibi and frame someone else. His chosen target was Delicy Scone, as her habit of snacking on the other contestants' hard work irritated him to no end. Kazami hid the body in a chocolate treasure chest that was in Tenkai's room, planning to retrieve it later and freeze it inside one of Holic's sherbet sculptures, so as to obfuscate the time of death and give him an alibi. He then left to have tea with the other contestants and establish his fake alibi.

However, the very bad habit of Scone's which so irritated him proved to be the undoing of his plan. Before Kazami had a chance to move the body, Scone entered Tenkai's room and nibbled her way through the chocolate supports holding up a pastry pirate ship, which caused the ship to tip over and break the lid of the treasure chest (although Scone herself left before this happened). The breaking noise attracted Tsukasa Oyashiki, a servant at the mansion, and upon discovering the body, Oyashiki ran off to call the police. Kazami bided his time until Oyashiki was out of sight, then entered the room, stole the body, and went ahead with his plan to freeze the body inside the sherbet sculpture. He also broke down the rock salt lamp that had his own blood on it, and mixed it with the remaining sherbet to fashion a lyre for the sculpture. Kazami's plan was to melt the sculptures and have whoever was nearby "discover" the body. However, he was foiled once again, this time by Oyashiki. Oyashiki had learned that "Isaku Hyōdō" was in fact Paul Holic, whom she was a great fan of. Fearing that the police investigation would damage Holic's work, Oyashiki moved the sculptures down to the basement of the mansion.

Due to where the body had been found, Issei Tenkai himself was accused of the murder, with Gregory Edgeworth taking up his defense in court. Edgeworth conducted a thorough investigation, but lead prosecutor Manfred von Karma's deliberately obstructive tactics prevented the investigation from really getting anywhere. Due to the fact that the body was missing, Chief Prosecutor Bansai Ichiyanagi provided von Karma with a forged autopsy report, which he had forced the elderly coroner Otome Itami to create. Edgeworth was able to prove in court that the report was forged, and Ichiyanagi was forced to penalize von Karma in order to shift suspicion away from himself. However, von Karma himself avoided further punishment by directing the brunt of the blame toward Police Detective Wataru Shirase, who was subsequently dismissed. In addition, von Karma's rigorous questioning tactics managed to force a false confession out of Tenkai, thus ensuring a guilty verdict. But Edgeworth had a trump card up his sleeve; he had recorded the confession as it had really happened, and presented the tape in court to prove that the confession was false. In spite of all of Edgeworth's efforts, judgment was passed and Tenkai was found guilty of being an accomplice to murder.

Purchase by OyashikiEdit

After Tenkai's arrest, the mansion was repossessed by his close relatives, and Tsukasa Oyashiki was kicked out due to having no blood relation to Tenkai. Oyashiki vowed that she would one day get the mansion back, and took up a career as an actress toward this end. In 2019, with some help from Tateyuki Shigaraki, Oyashiki was able to fulfill her goal, and set about renovating the mansion into a museum dedicated to Paul Holic. She was surprised to have found the sculptures she had hidden in the mansion's refrigerator 18 years ago. While inspecting the sculptures for the gallery, she finally discovered where Holic's body had gone; it was frozen inside the sculpture. Oyashiki devised a plan based on this to catch and trap Holic's real killer, the one responsible for framing Tenkai (or so she thought).

IS-7 solved at lastEdit

Main article: The Inherited Turnabout

In order to carry out her plan, Oyashiki removed the sculptures from the basement and placed them in the exhibit, then put the toxic chemical Fatallium in the case. She then froze an amount of the ordinarily harmless chemical Normallium onto the lid. When mixed, Normallium and Fatallium caused a gas that quickly became fatal to anyone who inhaled it. The idea of the plan was that the real killer would return to the mansion in order to remove the body. That person would then try to melt the sculpture case lid open (as the frozen Normallium would have sealed it shut). The temperature would cause the Normallium to melt and drip down the sides of the case, then meet with the Fatallium already in the case and form the gas. The real killer would then lift the lid of the case, thereby releasing the gas and completing Oyashiki's plan. It worked exactly as Oyashiki had plotted; Yutaka Kazami mixed the chemicals and lifted the lid, but after being overcome by the gas, managed to find enough energy to drag himself to the door of the exhibit. However, he found it locked; Oyashiki had also locked it in case the victim managed to find enough energy for an escape attempt. If not for the timely (if accidental) intervention of Larry Butz by opening the door, Kazami would have died. However, Butz opened the door, thus allowing Kazami to tumble out and escape death. Oyashiki immediately took Kazami to the second-floor infirmary, along with Delicy Scone, in order to shift suspicion. Miles Edgeworth, who was visiting along with Tateyuki Shigaraki, quickly made to investigate the cause and perpetrator of the gas, but they were stopped by Yumihiko Ichiyanagi and Hakari Mikagami, a rival prosecutor and judge who had arrived to do their own investigation. Ichiyanagi introduced Butz as a suspect, due to the fact that he had been carrying a red paint that contained Normallium. Edgeworth quickly dashed his logic into pieces by pointing out that Butz would not have had access to Fatallium. Ichiyanagi then placed suspicion on Delicy Scone, due to the fact that she knew how to make the gas, being a pharmacist. He added that Scone also carried a bottle of a pesticide called "Megatoxin X" at all times, the active ingredient of which was Fatallium. However, Scone was able to prove that her bottle of Megatoxin X had in fact been stolen one week prior to the incident, thus clearing her of suspicion. Ichiyanagi eventually agreed to let Edgeworth assist with the investigation, and Edgeworth used this authority to track down Oyashiki as the real culprit of the gas. However, both Edgeworth and Shigaraki had noticed that all the people involved with IS-7 seemed to be congregated at the museum, and they quickly set out to finish what Gregory Edgeworth had started 18 years ago. Edgeworth suspected Kazami, due to the fact that he had set off the gas, but a lack of decisive evidence prevented a formal suspicion, and Edgeworth was forced to resort to a mixture of logic and manipulation in order for the investigation to go anywhere. Once Edgeworth had uncovered a motive, he investigated further and found that numerous pieces of evidence pointed to Kazami. Kazami, trapped, openly confessed to his crime, but pointed out that the statute of limitations on the IS-7 case had run out, meaning he could not be convicted. However, Edgeworth drove Kazami into a corner by revealing that Tenkai had only been convicted as an accomplice, which meant that the statute was extended by a year if the accomplice's partner could not be found. As a result, Kazami was finally brought to justice.

After the resolution of IS-7 and the gas trap, Oyashiki was presumably arrested and tried for attempted murder. Since Tenkai was set free after Kazami's conviction, there is a high probability that the mansion is once more in his possession. Whether or not it is still a museum is unclear.     


There are four main rooms in the gallery, called "palaces", each named after a specific season. All of them are decorated and have a temperature corresponding to their seasons, and house specific sculptures by Holic, all of them named after constellations:

Additionally, all rooms are equipped with sprinklers, which are manually controlled from the security room on the first floor. On the second floor, there is a medical room, equipped fully enough to create a poison antidote on the spot.


In the fan translation of Gyakuten Kenji 2, the 12 Constellations Art Gallery is slightly renamed to the "Zodiac Art Gallery".
