|She always puts aside her own preferences and things that she wants to do herself. ...I want Tsukasa to choose to live her own life. I do not want her to waste her valuable life because of me.|
Tsukasa Oyashiki was a housekeeper who worked at Issei Tenkai's mansion, as well as being his program partner on the musical cookery television program Dansweets. After Tenkai was incarcerated for murder, Oyashiki worked as an actress until she could afford to buy back his mansion and turn it into the Zodiac Art Gallery, of which she became the curator.
Oyashiki was abandoned by her biological parents at Tenkai's doorstep on Christmas Eve, so he took care of her and raised her as his own daughter. She occasionally tried to mimic his skill in the kitchen to various levels of success. Oyashiki worked hard in the kitchen and on Tenkai's show, Dansweets, as a means of expressing her gratitude. She regularly made chocolate for Tenkai, his favorite food. She also became a fan of the French sculptor Paul Holic, some of whose works were on display in the mansion.

In December 2000, Tenkai held a confectionery competition at his mansion to find someone worthy to receive the "Angel's Recipe", a document from the Tenkai Group pharmaceutical company that his late father had owned. The Angel's Recipe contained various "recipes" for as-yet unreleased pharmaceuticals, and included procedures for making a cure for ageusia and hypogeusia. The Tenkai Group disapproved of Tenkai just giving away their trade secrets like this, so they sent one of their own, Delicy Scone, undercover to participate in the competition and win the prize. Oyashiki wanted to protect Tenkai, so she secretly agreed to help Scone with her dessert entries.
As part of his judging of the competition, Tenkai would take photos of everyone's work. However, he ran out of film during the finals, so Oyashiki went upstairs to fetch more. When she came back, she heard a crash coming from Tenkai's room. She investigated and found the body of Isaku Hyōdō, one of the competitors. Seeing the "PH" design on his ring, she immediately realized that he was Paul Holic. She took a photo of the scene and left to inform the authorities, but by the time she returned, the body was gone.
Tenkai was accused of the murder, and Gregory Edgeworth took on his case with Tateyuki Shigaraki acting as his assistant. Hyōdō's entry was a set of sculptures modeled after the 12 constellations of the zodiac and made of frozen sherbet; Oyashiki feared that they might be tampered with by the police during their investigation. Because of this, Oyashiki took photos of the completed sculptures from various angles, and transported all of them to the house cellar, one by one, using a tablecloth and baggage lift. The tablecloth covering the casings made the set-up look like a tea cart rather than a lift, and she even served tea to Edgeworth and Shigaraki, with the only hint of the sculptures underneath being that the saucers were cold. She also melted the unfinished sculptures, and later claimed that she must have tripped over the refrigerator wires as she was taking pictures, causing all of the sculptures to melt. During this time, she saw Yutaka Kazami, one of the contestants, entering the victim's room.
Although the police under Manfred von Karma claimed that the victim's body was in their possession, Edgeworth soon deduced that the corpse had gone missing. In court, von Karma presented a forged autopsy report, and the police backed him up on its legitimacy. The trial lasted a year until von Karma was able to force a false confession from Tenkai. Edgeworth was able to prove that the confession had been forced, but the trial ended in a conviction for being an accomplice to the murder. Edgeworth's accusation resulted in von Karma's first and only penalty, and the beginning of the infamous DL-6 Incident.
After Tenkai's conviction, Oyashiki was kicked out of his mansion by his relatives. She visited Tenkai and made chocolates for him every day. She swore that she would buy the mansion from Tenkai's relatives. Eventually, she became a world-famous actress. After obtaining enough money to buy back the mansion, she retired from the business after 18 years and hired Scone as a resident pharmacist.
Exposing the truthEdit
- Main article: The Inherited Turnabout
By the time she had bought back the mansion, the statute of limitations had run out on what became known as the IS-7 Incident. The real culprit would be immune to prosecution unless they had been out of the country for three years. Oyashiki found the sculptures that she had hidden all those years ago, only to discover that Hyōdō's body had been frozen inside the Gemini sculpture for all that time. The body had been disguised using one of Scone's fluorescent cloths, which she had used to decorate her entry against the rules. Oyashiki decided to take matters into her own hands and lure out the killer herself.
Realizing that only she and the true killer would know where the body was, Oyashiki turned the mansion into an art gallery dedicated to the works of Paul Holic, where she would claim that the sculptures were replicas of the originals. A week before the grand opening, she stole Scone's bottle of Megatoxin X. Having bought the Angel's Recipe along with the mansion, she found out how to make a poisonous gas using normallium, a commonly available substance, and fatallium, the active ingredient in Megatoxin X.
On the day of the grand opening, Oyashiki placed the sculptures in the four rooms on the first floor, themed after the seasons. However, she intentionally put the Autumn and Winter Palaces in the wrong order, and used Scone's fluorescent cloths to disguise the Autumn Palace sculptures as the Winter Palace sculptures. She booby-trapped the Pisces sculpture, disguised as the Gemini sculpture, with the Megatoxin X and a sample of normallium, which would mix and form a poisonous gas if anyone opened the sculpture's case. She then locked the other rooms, leaving only the Autumn Palace open.
Sure enough, Kazami arrived early and took the bait. He locked the Autumn Palace door from the inside to examine the sculpture alone, while Oyashiki opened the other rooms in preparation for the official opening of the museum. Kazami eventually reopened the Autumn Palace door, having triggered the trap, and collapsed, but he had managed to escape before the gas did too much damage. He was sent to the infirmary to recover, and Oyashiki planted the bottle of Megatoxin X in his pocket to make the incident look like an attempted suicide.
Kazami was not the only one who had been drawn to the gallery. Shigaraki brought Miles Edgeworth, Gregory's son, to look at the sculptures and talk about the IS-7 Incident. They were thus thrust into an investigation of the poisoning incident. Meanwhile, Oyashiki moved the real Winter Palace sculptures and the normallium that she had used, using the same method as before, and took the sculptures to the Summer Palace, where she dumped them into a stream that led to the fountain at the entrance. The body eventually thawed and floated to the surface, finally revealing that Isaku Hyōdō had never left the scene of his murder after all.
Eventually, Edgeworth figured out what Oyashiki had done, and accused her of both the attempt on Kazami's life and Holic's murder; she admitted the former crime, but strongly denied the latter, and Edgeworth realized that Kazami himself was Holic's murderer. When confronted, Kazami claimed that he could no longer be arrested due to the statute of limitations having expired. Oyashiki began to despair, but Shigaraki convinced her not to resort to further drastic measures. It was soon revealed that the statute of limitations was extended due to Kazami's three-year stay in Zheng Fa, as well as the fact that Tenkai had been tried as an accomplice to the murder for one year, and eventually found guilty. This allowed Kazami to finally be arrested for his crime.
Oyashiki was charged with tampering with a crime scene and attempted murder, but Shigaraki offered to be her defense attorney. At that, Oyashiki smiled with tears in her eyes and happily accepted the offer before being reluctantly placed under arrest by Detective Dick Gumshoe. A freed Tenkai later stated that it was now his turn to wait for her, as she had been doing for him for all those years.
Oyashiki was polite to a fault, and always eager to play the generous hostess, but could at times be slightly over-dramatic. She was greatly devoted to Tenkai, to the point of doing everything for his sake rather than her own desires. Due to the expiry of the statute of limitations on the IS-7 Incident, she was willing to take drastic measures to expose the truth behind the murder for which Tenkai had been arrested, even if it meant taking a life.
- Her full name is a play on the Japanese phrase "o yashiki o tsukasadoru" (お屋敷を司る), which means "[to be] responsible for the residence".
- The kanji (屋敷) in her surname mean "resident or mansion" (explained in-game as Tenkai naming her after where he found her), but may also be a play on "Okashi" (お菓子), which means "sweet" or "candy". "敷" by itself means "blanket" or "table cloth"; likely a reference to how she moved Hyōdō's body.
- Her English name in the fan translation of Gyakuten Kenji 2 is "Katherine Hall", which is likely a pun on "catering hall", in-fitting with the chef theme. This is further established by her given nickname, "Kate".
