The IS-7 Incident refers to a murder that took place in the mansion of Issei Tenkai on December 24, 2000. It directly led to the DL-6 Incident and indirectly affected the SS-5 Incident. The incident revolved around the trial of a famous television chef, Issei Tenkai, who had been accused of killing Isaku Hyōdō. His defense attorney, Gregory Edgeworth, faced the infamous prosecutor Manfred von Karma. He lost the case, but he managed to prove that von Karma had to manipulate the autopsy report, since the victim's body was never found. As a result, Tenkai was charged with accomplice to murder instead and von Karma was given a penalty, the first and only one he had ever received. The case was put on hold for 18 years, because the witness and only other suspect, Yutaka Kazami, fled to Zheng Fa.

The IncidentEdit

Main article: The Inherited Turnabout

Famous TV chef, Issei Tenkai, decided to hold a competition at his mansion to see who was the greatest pastry chef in the world. The prize was a "recipe book", Angel's Recipe, containing experimental drugs which included cures for both hypogeusia and ageusia, Tenkai decided that he would give it to someone he respected. Aside from Tenkai himself, there were three known competitors: Yutaka Kazami, who wanted the book to cure his Ageusia, Paul Holic, under the pseudonym, Isaku Hyōdō, who wanted to sell the book for a lot of money, and Delicy Scone, a spy sent by the Tenkai Group in order to keep the book to itself. Hyōdō and Kazami lacked certain skills, so they decided to collaborate together, Kazami makes the sweets and Hyōdō sculpts them.

However before the final round, Hyōdō, seeing he had everything he needed to win, broke their collaboration and refused to sculpt Kazami's batches of sherbet. To make matters worse, Hyōdō had his own son, Manosuke, tie Kazami's son, Sōta, in a freezing car so he couldn't use him to taste his sweets, those two were eventually saved by the blind assassin Ryōken Hōinbō and his dog Kuro.

Kazami Caught

Knowing there's no way he'd win the competition now, Yutaka Kazami decided to sneak into Tenkai's room during the afternoon tea and take a picture of the cure for his hypogeusia in the Angel's Recipe book. Holic, however, walked in, found out about his condition, and mocked his former collaborator. Kazami attacked him but Hyōdō landed the first blow and Kazami struck his head on one of the two salt lamps getting his blood on it. Hyōdō then threatened to expose his condition and attempt of thievery to the world unless he paid a hefty fee. Kazami responded to this by grabbing the other salt lamp delivering a blow to Paul Holic's head, killing him.

Kazami intended to frame Delicy Scone for the murder because he had learned that her entry was merely a thin layer of confectionery over a model base and was thus cheating. He cleared his own blood off the rock salt lamp by mixing it into the lyre of Holic's sculpture, hid both lamps inside Scone's dessert, and hid Holic's body in the treasure chest of Tenkai's creation, wrapped in one of Scone's fluorescent cloths. Kazami also planned to freeze the body, in order to throw off the time of death, and then dispose of the lyre containing his blood.

However, Scone sneaked into Tenkai's room and sampled some of the desserts there, including the chocolate ship. Later, while Tenkai was judging Kazami's entry, the ship fell down and broke open the treasure chest below, causing Tenkai's assistant and adopted daughter, Tsukasa Oyashiki, to enter the room to investigate the noise, and discover the body. She also saw the signet crest next to the body, and realized that Hyōdō was actually Paul Holic. She took a photograph of the scene, and called the police to report the discovery. Kazami then moved Hyōdō to be frozen inside the Gemini sculpture as he had planned. Before the police arrived, however, Oyashiki went to Holic's room with her camera, where she took several photos of his final works. She then removed the sculptures, fearing that the police would damage them during their investigation, and hid them in the mansion's freezer. She then unplugged the glass cases’ coolers, making it appear as though the sculptures had melted. But, since the body was discovered early in his room, Issei Tenkai was arrested for the murder of Isaku Hyōdō instead of Delicy Scone.

Summoning and trialEdit

The original detective assigned to this case was Wataru Shirase, but he was moved to interrogations and replaced by Tyrell Badd. The prosecutor was the legendary, undefeated Manfred von Karma. Issei Tenkai hired veteran defense attorney Gregory Edgeworth and his assistant Tateyuki Shigaraki to defend him.

We need more pieces to finish this puzzle.

The trial lasted a whole year due to a lack of evidence, throughout which Gregory's son Miles would watch from the gallery. After von Karma had Shirase threaten to Tenkai that Oyashiki would be indicted, Tenkai confessed to being an accomplice. Having requested that Badd record Tenkai's interrogations, Edgeworth showed the recording of the confession in court, proving Tenkai was coerced.


Although he won the trial, Manfred Von Karma was penalized by Chief Prosecutor Bansai Ichiyanagi, the only penalty he ever received in all his years as a prosecutor. Wataru Shirase was also fired from his job as a police detective due to the forced confession. Not long after the trial, an earthquake struck the courthouse, leading to the DL-6 Incident.

Reopening and resolutionEdit


Paul Holic frozen corpse is finally found.

Three years after DL-6 was resolved, Edgeworth, with the help of his father's old partner, Shigaraki, solved the IS-7 Incident and was able to figure out that Kazami killed Hyōdō when Oyashiki tried to poison Kazami as revenge. Though Kazami believed the statute of limitations on the case had already expired (even accounting for his time spent in Zheng Fa), it had been extended one further year because Tenkai was convicted as an accomplice. Tenkai's false charge allowed for Kazami's arrest after 18 years, but with the question of whether or not his arrest would hold after clearing the false charge (thereby shortening the statute of limitations). With Yutaka Kazami arrested, Issei Tenkai was finally set free.

A few days later, new light was shed on DL-6. Examination of the IS-7 case files revealed that Bansai Ichiyanagi had made Otome Itami forge the autopsy report, and penalized Von Karma to cover his involvement in the forgery. As such, Von Karma never learned the impetus behind the events leading to Gregory Edgeworth's death.
