I don't own Persona 5, it belongs to ATLUS. I only own my OC, Aika Saito while the other OC, Keiko Amamiya belongs to my friend and fellow fanfiction author, Tmdrago.
Prologue
Under the night sky filled with dozens of bright stars, a single helicopter flew above and across the huge and dark ocean toward the brightly lit and myriad colours of Tokyo, one of the large cities of Japan. The helicopter flew past several tall and large buildings and skyscrapers and toward a certain building in the middle of it, which turns out to be a tall and large casino building with a brightly lit red, light blue and yellow figure of a woman dressed like a cowgirl standing in front of the building and holding up a pair of light blue and yellow-coloured scale thing with the large and single word "WIN" highlighted down in neon light, like the cowgirl.
Meanwhile, inside one of the large slot machines room filled with guests within the casino, several alarms on the walls were blaring quite loudly in the room, which caused several security guards wearing black suits and black glasses on them to swiftly make their way past the guests to search for the troublesome cause of the commotion while the guests look swiftly around the room with anxious, confused and worried looks on their faces (while not noticing a single shadow figure jumping over one chandelier after another above them).
"Huh…?" said a woman with an anxious and worry look on her face.
"There's something or someone here!" said a man as he look around the room while 3 more black suits and glasses security guards men came walking and looking around the room.
As the guards continue to look around the room for the cause of the commotion, the shadow figure jumped from the chandelier and landed on another one before the figure slowly stood up and turned around to glance down at the guests and guards standing below with a smirk on the figure's face.
"H-Hey, look! Up there!" said another man as he spotted, raised and pointed his finger at the shadow figure standing on the chandelier before the rest of the guests look up at the figure as well and they saw that the figure is a young, fair-skinned, grey-eyed, long and curly raven-haired girl wearing a high-necked grey waistcoat with gold accents and with a long sleeve, ankle-length black tailcoat over it, long jogger-style black pants and black heels on her feet, a pair of red gloves on her hands and a bird-shaped black and white domino mask on her face while she carry a light grey suitcase under her left arm.
"She's here. Moving in immediately for capture." One of the guards spoke into the earpiece in his ear before he and his 2 fellow guards began to make their way past the guests toward the chandelier where the girl is.
The masked girl smirked confidently as she watched the 3 guards started to make their way toward her before she turned around to jumped off the chandelier and into the darker recesses of the casino. As she continue to moved on, she briefly stopped to hand over the briefcase that she carried under her arm to one of her teammates, which is another fair-skinned, purple-eyed, long light blue-haired girl wearing a dark blue, purple and green-coloured sleeveless, knee-length dress with a waist-length black cape on her back, dark blue fingerless elbow-length gloves on her arms, thigh-high black stockings and knee-length grey boots on her legs and a white butterfly mask on her face.
"Here, take it, Jester." said the masked girl to the other masked girl called Jester.
"Right and are you sure about this, Joker?" said Jester concernly to the masked girl called Joker.
"Yeah, I'm sure because there's no turning back now, Jester." said Joker firmly to Jester.
"… Good luck to you, Joker." said Jester before she stood up, turned and run away with the briefcase while Joker watched Jester run away before she stood up, turned and jumped out and landed on a glass walkway.
"Good. Now get running!" said a boyish voice to Joker.
"This is our only chance!" said a second boy's voice.
"Stay calm! You can get away now!" said a girl's voice.
"Good job in handing the briefcase over to Jester, Joker." said another girl's voice to Joker before she heard a garbled man's voice talking to another. "Hm…? What was that…?" said the second girl's voice in confusion.
"Don't worry about us. Just concentrate on getting away!" the boyish voice told Joker, who nodded before she began running then jumping from one glass walkway after another and jumped onto another chandelier. "But I have to say, showing yourself above that crowd earlier so boldly was an excellent move! Nice work as always, Joker." added the boyish voice in a compliment tone of voice to Joker.
"I bet Skull wouldn't pull such a stunt off that smoothly like her." said the third voice of another girl.
"This happens because you have no sense for the aesthetics." said the exasperated, slight deep and refined voice of another guy to the other guy that the other girl just teased about.
"How right you are about Skull, Fox." said Jester in agreement to the voice of the deep and refined guy called Fox.
"Nobody asked you, Fox! And you too, Jester!" snapped the casual and boisterous voice of another guy called Skull to both Jester and Fox.
"Aw, what's the matter? You jelly about it, Skull?" said Jester teasingly to the guy called Skull.
"Enough with the meaningless bickering and teasing among yourselves, everyone." said Joker to her teammates as she rolled her eyes and shake her head a little before she came to a stop on the chandelier when she saw 3 guards coming out of an exit door which she was supposed to head to.
"Shoot! Run and get out in another direction, Jester!" said the first girl's voice anxiously to Joker before she quickly turned to her left and began jumping across several glass walkways.
"Ok, the enemy's focus is on her. Looks like the rest of us can slip away safely." said the boyish voice.
"Everyone remember where we are meeting up?" said a fourth girl's voice to the others.
"No worries, I can guide you all." said the first girl's voice reassuringly to the fourth girl.
After Joker's teammates done in talking to each other and fell into silence, Joker jumped from the last glass walkway and landed on an archway before she jumped up from the archway and over the railing and landed on the second floor. As Joker turned around and was about to run forward, she saw 2 guards running and came to a stop at the top of the steps a few feet away in front of her before their bodies started shaking then changing into some kind of black-skinned, cold yellow-eyed monsters with steel masks on their faces. Joker then heard the sound of someone landed on the second floor with a loud thud sound behind her and when she turned around for a look, she saw a third black-skinned, cold yellow-eyed monster standing in front of her.
"Take it down, Joker!" said the first girl's voice to Joker.
"Of course I will." said Joker with a smirk on her face before she jumped up, landed on the shoulders of the masked guard before she grabbed hold of his mask and forcefully ripped his mask away from his face (which reveal a black and blank face with bright red-coloured eyes on it). After Joker ripped off the mask of the guard and jumped away from him, the guard's entire body began to turned completely black with dozens of red veins on it before the guard began to shake quite wildly then explode outward in a big gush of blackish-red liquid before the liquid abruptly dissipated away to reveal a tall, red-eyed, black, blue and yellow beast-like bull creature standing on it's legs, wearing a white cravat at it's neck and a large tail behind it.
"Now comparing power levels… No threat. Get'em, Joker!" said the first girl's voice to Joker (who nodded before she pull her handgun out of the right pocket of her coatand proceed to fired her handgun relentlessly at the bull creature (which make it yell out in pain from her relentless gun attack) until she defeated the creature and it burst apart into a dozen black ashes and scatter in different direction in the air).
"Ok, now pull out before their backup gets here." said the first girl's voice to Joker.
"Good. You defeated it with ease!" said the boyish voice proudly to Joker.
"Of course she did. It's piece of cake to her!" said Jester in agreement to the boyish voice of the guy.
"More of them here already!? Be careful!" warned the first girl's voice to Joker before 3 more guards suddenly appear in front of Joker (which surprises her a little). The middle guard then charge toward Joker with his electric rod raised high above him in preparation to strike down on her. Joker smirked at the guard before she backflip away from the guard swinging his rod down on her before she jumped up and landed on another archway, jumped from the archway and over another railing and landed on the third floor.
"Joker, behind you! Go through that opened door now!" the first girl's voice told and order at Joker (who immediately turned around, run toward and through the opened door and run up the stairs until she came into an empty inner room within the casino).
"You should be able to get out that way! Hurry, Joker!" said the first girl's voice.
"H-Hey, can she even hear us!?"asked Skull worriedly to the first girl's voice.
"Don't worry, I'm picking up on everyone's voices! Just go, Joker!" replied the first girl's voice Skull before she told Joker to hurry and go (which Joker did as she run forward in the room before she turned to her left, opened and run through the door and down the stairs then she turned to her right, run down a short hallway toward another door, opened it and went into another room (which had 3 large rectangular-shaped windows in the room and several wooden crates lying on the floor against the walls).
After Joker run into the room, she noticed with a scowl look on her face that there's one of the guard standing with his back to her between the other opened door and the other staircase leading up to the exit before she swiftly hide and moved herself behind the crates closer toward the opened door while avoiding being seen by the guard. After Joker hide herself behind the crate near the door, she overheard the guard speak to his fellow guards about her before the guard turned around and run past the wooden crate that she's currently hiding behind before she came out of her hiding place and quickly run through the door and up the stairs.
Joker run up the stairs before she reached and came into an inner corridor within the casino. She then run forward down the corridor before she came to a stop near a large rectangular-shaped window to look inside and saw a room filled with some peoples typing away at the computers on the tables while others watched the dozens of TV monitors on the walls in front of them to search for any sights of herself or her teammates before she swiftly and discreetly run past the room down the corridor, run up several staircases and into another corridor leading toward a single door.
Joker then run down the corridor toward the door, opened and run through the door and she came to a stop at a railing.
"Something wrong? The exit should be up ahead." said the first girl's voice to Joker.
"Through there, huh?" asked Joker as she glance forward and saw a large myriad-coloured window not far in front of her.
"Nhh…! That's just how it is. After the commotion, the bottom floor's-" sighed the first girl's voice before her words got cut off by the third girl's voice.
"-completely closed off! H-hey, can you make it!?" asked the third girl's voice worriedly to Joker.
"Of course I can." replied Joker as she smirk in excitement.
"Over there!" "Don't move!" "There's nowhere to run!" said the voices of the guards from behind Joker (who turned around and saw 3 guards slowly approaching her with their guns raised and aimed at her in their hands).
Joker smirked at the 3 guards before she turned and jumped onto the railing (which surprises the 3 guards before they quickly run down the corridor and out the door) and took off running down the railing toward the window until she reached and came to a crouching stop near the window and glance at the 3 guards.
"Later, boys." said Joker as she blew a kiss to the 3 guards before she jumped from the railing toward the window with her arms over her face and head and threw herself through the window.
"Hmph. What a showoff!" scoffed the first girl's voice to Joker.
"You're so reckless. You know that, Joker?" said the second girl's voice before she let out a sigh at Joker.
"You guys have no idea when it comes to how reckless she is." said Jester in an exasperated tone of voice to the second girl's voice.
"You've a point, Jester." sighed the second girl's voice.
Joker smirk at her teammates words to her before she fell and landed safely on her feet on the ground in a crouching manner. She then dusted herself a little before she stood up from the ground but soon after she do so, dozens of spotlights suddenly light up in front of her, which make her let out a small gasp of surprise as she raised her right arm to shield her eyes from the sudden appearance of the lights shining on her. Once her eyes adjusted to the lights and she lowered her arm to take a look, she immediately scowled at the scene of a large group of armed police forces in front of her. "Oh shoot. This isn't good." thought Joker to herself in her mind.
"Enemies here!? These readings… it can't be!" said the first girl's voice worriedly.
"What's wrong!?" said the second boy's voice.
"What happened!?" said Skull worriedly.
"An ambush!?" said the fourth girl's voice worriedly.
"Joker, can you handle this!?" said the boyish voice.
"Joker!?" said both Jester and Fox worriedly to Joker.
"Joker! Oh no!" said the third girl's voice worriedly to Joker as well.
"Capture her!" yelled the captain of the police forces through the loud speaker he carry in his right hand to his fellow policemen, which spur some of them into action and they immediately run toward Joker.
Joker scowled even more at them before she turned to her right and began to run toward the nearby fire escape ladder away from some of the police officers chasing after her (while the lights shining on her followed her to keep her in sight). Once Joker reached the ladder, she quickly jumped, grabbed and began climbing up the ladder away from the officers chasing after her.
Joker smirked and chuckled at the officers raising and swinging their rods below her in anger as she kept on climbing up the ladder but when she look up, she gasped and widened her eyes in shock when she saw several officers standing and kneeling on the metallic catwalk above her. One of the officers then raised and slammed the butt of his rifle down on her face, which make her release her grip on the ladder before she fell down and landed into the midst of the police officers standing below, who immediately grabbed and pinned her to the ground, not letting her have the slightest chance of escape.
Soon after the police officers grabbed and pinned Joker to the ground, they began to part to allow a cold and menacing-looking detective man walked toward her. "Huh. Didn't expect to find and see some girl." said the detective man coldly to Joker as he kneel down to grabbed a fistful of her hair to pull her face up for a closer look. "You have one of your teammates to thank for this. You… were sold out." the detective man added smugly to Joker before he let go of her, stood up, order one of the police officers to handcuffed Joker (which the police officer did) before he turned to walked away and the police officers rudely bring Joker up from the ground and bring her away with them.
