- "The second you put it in your mouth, you sense that something is wrong... You can tell after one bite that this isn't edible... There's no way you can swallow it..."
- —The message as the protagonist attempts to eat the first incarnation, Persona 4
Mystery Food X is a substance featured in the Persona series, specifically in the Persona 4 series of games. It refers to "food" cooked by the female members of the Investigation Team, used in several scenes for comedic value.
- Persona 4 / Golden
- Persona 4 Arena
- Persona Q: Shadow of the Labyrinth
- Persona 5 Anthology
In all its incarnations, Mystery Food X is an attempt at making food gone wrong. All Mystery Food X is noted for their generally unpleasant taste, though the potency of the flavor ranges from mildly discomforting to outright disgusting. Particularly potent Mystery Food X give off a purple miasma and has a particularly foul smelling aroma accompanying it. It originally was used as a label for the curry meal that Yukiko and Chie prepared for Yosuke Hanamura and the P4 protagonist. Later, the term has been used for any meal prepared by Yukiko Amagi, Chie Satonaka and Rise Kujikawa. Each of their meals have a particular aspect which classifies it as Mystery Food X: Chie's food is shown to be generally unpleasant, Yukiko's are either tasteless or oddly textured due to her use of unusual ingredients, and Rise's are extremely spicy due to overuse of spices and hot peppers. The girls seem to be unaware of their poor cooking skills given that they never taste their own food nor do they ever eat their own finished dishes.
In Persona Q, Fuuka Yamagishi is classified as another Mystery Food X maker (although unlike the P4 girls, she acknowledges her poor cooking skills). Collectively, the four Mystery Food X creators substances are toxic enough to kill an F.O.E. in a single shot.
- "WHAT THE HELL IS THIS!? I mean, what kinda - *cough cough* Curry's supposed to be like "really spicy" or "kinda mild"... This just stinks! And it's gritty too! It's somehow both gritty and slimy... And it's got squishy parts in it... It's so frickin' nasty I can't even swallow it!"
- —Yosuke's reaction to the curry.
When the protagonist, Yosuke Hanamura, Yukiko and Chie go with the rest of the Yasogami High students on the school camping trip, Yukiko and Chie take it upon themselves to make curry for their end-of-day meal. The protagonist sees them by chance getting ingredients. When at camp, despite its unpleasant appearance, the two cooks feel unable to taste it themselves, so give it to the boys. When Yosuke tastes it, he spits it out and momentarily keels over. After berating the girls, they insist that the protagonist try it. If their courage is not high enough, they will not be able to, but even pretending to eat it shows the protagonist how bad it is. This leaves them as the only group of students without food.
A similar experience is felt in August after the party defeat Mitsuo Kubo: as part of the celebrations for apparently solving the case, the protagonist, Yukiko, Chie and Rise prepare omelets for Nanako at the Dojima residence. Though Yosuke is excited to try Rise's, his excitement turns quickly to shock as her omelet is alarmingly spicy, so much so that the protagonist feels that their mouth is filled with lava. Yukiko's ends up being completely tasteless, which Kanji describes as eating plain oatmeal. Finally Chie's one is outright terrible in taste. Despite all this, Nanako tries each of their omelets and tells them that she thinks that they taste good, despite some slight grimacing from her. After trying to figure out which one was worse, Yukiko tries Rise's omelet which promptly knocks her out. In the end, the protagonist's omelet is the only one that actually tastes good and wins Nanako's overall approval as the best of the four.
The boys also fear another repeat of events at the Chrismas party to celebrate Nanako's recovery after being kidnapped and forced into the Midnight Channel. The girls insist on making a cake for her, much to the boys dread of possibly sending Nanako back to the hospital in worse condition. However, despite some reluctance, the boys are shocked to find out that the cake is not only in presentable fashion, but also delicious. Thanks in part to Naoto Shirogane, who insisted on following the recipe, the cake managed to come out normally. However, Naoto reveals that it took them three tries to get the result. Yosuke attributes the entire success to Naoto.
During the bonus Valentine's Day event, should the protagonist go on the date with Rise, before the protagonist even opens her chocolate, he can sense that something about it is off by the aroma of it. She reveals that she added durian and habanero into it to make it extra special. The protagonist manages to convince her that he will eat it later, promising to tell her later how it tastes. Yukiko ends up giving him gourmet chocolates made by the staff of the Amagi Inn. It is revealed that she originally was making chocolate her way, by adding squid ink, but the inn staff members intervened. Chie hands him a misshapen heart chocolate, but it is only mildly unpleasant and runny as she added too much water to her chocolate, unable to get it to temper properly.
On a separate note, if the protagonist decides to meet up with Marie, she presents him with chocolate that she made in the Velvet Room, doing the best she could without having any access to "eclectic loutwits." The chocolate gives off an unpleasant smell, and, more importantly, seems to move inside the box. The protagonist is alarmed when Maire tells him that "If you don't hurry, it'll melt" and "If it melts, it'll run away." Despite feeling a sense of danger, the protagonist tries the chocolate, only to discover that it tastes quite normal and soon eats it all, much to Marie's shock. However, he is left with the unsettling feeling that something is moving within his stomach.
Later that day, Nanako decides to make chocolate for the protagonist and enlists the help of the Investigation team girls for advice on how to make it. She added iced coffee and bacon from Chie's suggestions, bell peppers, wheatgrass juice, vinegar, and ponzu sauce from Rise's, and fish sausage and fermented squid from Yukiko's. Nanako's combination of the girls' advice results in Slime shaped "chocolate," causing the protagonist to be very alarmed. Naoto also contacted Nanako, but she had already completed her chocolate by then. Naoto simply assured Nanako that the protagonist would appreciate it in the end. Although he nearly backs out of eating it, Nanako's innocent comment declaring that she loves him forces him to eat it to keep her happy. Unfortunately, the "chocolate" causes him to black out.
- "It's gritty and slimy and mushy all at the same time! No matter what you do to it, it'll still be totally gross!"
- —Yosuke Hanamura berating Yukiko Amagi and Chie Satonaka for creating the food in Persona 4: The Animation
The events of the Camping Trip plays out exactly the same as the game. However, an additional scene occurs where Hanako Ohtani tries Chie and Yukiko's curry. Much to everyone's surprise, not only does she manage to stomach the food, she finds it delicious.
Persona 4 ArenaEdit
Mystery Food X makes a minor appearance as a trophy. To get it, the player must spam Teddie's crouch or jump button until he throws some curry onto the field, then pick it up before the enemy. Doing so will earn the trophy, but also poison Teddie.
Persona Q: Shadow of the LabyrinthEdit
During the Persona 3 side of events, during their exploration of the Evil Spirit Club, Yukiko offers some cookies to Zen and Rei. Rei has them and initially seems fine, but when Zen has them, he freezes in shock and seems to faint on his feet. Rei then faints herself immediatley afterward. When the two regain conciousness, the former says she dreamt she was being held down with sand being poured into her mouth. This provokes the P4 protagonist and Yosuke to wonder how much more Mystery Food X will "evolve" now that it has become a "delayed-action hallucinogenic." Mitsuru Kirijo expresses an interest in Yukiko's cookies, finding military value in their effects.
- "I call this "Mystery Food X: The Final Edition"... It's a weapon that's surpassed all my expectations..."
- —Naoto describing Mystery Food X in its most potent form.
In the Persona 4 side, when the group enter the final Culture Festival labyrinth, the group are confronted by the Macho Man F.O.E, forcing the group to flee. While the boys take one route and Kanji is captured by the F.O.E, the girls go another way, finding temporary safety. If the protagonist goes with them, they see in full detail what happens. As the F.O.E approaches, Naoto has the idea of using the girls' food to create a powerful weapon against the F.O.E. They use the contents of a lunchbox prepared by Yukiko, a blue muffin baked by Chie, red cookies made by Rise that she gave to Chie, and molten beef stroganoff rice balls prepared by Fuuka which were being carried by Aigis. Either at the protagonist's suggestion or on her own, Naoto mixes them all up, creating what she dubs "Mystery Food X: The Final Edition"; a concoction so potent that it stings Rei's eyes and causes Zen to refer to it as "a chemical weapon." When the F.O.E appears with Kanji, Zen fires arrows dipped in the substance at it. The first shot accidentally hits and incapacitates Kanji, but the second strikes the F.O.E and kills it outright. Kanji in a haze manages to steady himself only to collapse, but still miraculously make a full recovery. Mitsuru is so impressed that she voices her desire to take it for examination and replication at the Kirijo Group's R&D labs, much to the other girls' chagrin, and Naoto followed by saying such attack was the only choice available that time, and cannot be reproduced again.
Persona 4: Dancing All NightEdit
Mystery Food X is brought up at the end of the story when Kanami makes the Investigation Team a boxed lunch as thanks for rescuing her and solving the case of the game. Most of the guys fear that Kanami's food will be like the other girls, but much to their surprise, they find her food to be delicious.
During the bonus prologue, Yukiko mentions during her interview that she has continued to practice how to cook. When Minoru Inoue expresses a desire to try her cooking someday as a visitor at the Amagi Inn, the boys quickly try their best to deter him, stating amongst themselves that they will not allow anyone else be a victim to the girls cooking like they were to their curry. Later, the Investigation Team and Inoue is invited to the Dojima Residence and the girls quickly offer to help cook the meal. While Inoue is excited to get a sample of "Amagi cooking," the boys are less than excited to hear that they will help.
Persona 5 Edit
In the manga anthology, after a curry fixing mishap, Akira Kurusu requests aid from his fellow Phantom Thieves and heads into Mementos, robbing money from the Shadows to buy ingredients. Yusuke Kitagawa creates his own variation of Mystery Food X while trying to implement his own artistic style into the curry.
