I don't own Persona, JoJo's Bizarre Adventure, or the 7th stand user. All respective properties belong to their respective owners.
This story is based around the 7th stand user and Persona 3. It takes place before the stardust crusaders enter DIO's mansion and a few days before Aigis joins the SEES group. If you haven't played either games then I highly recommend you do. To make things clear [STANDS] are superior to personas in terms of creativity and battle prowess, while personas are more versatile in what they can do they still are limit to certain move sets. A key factor in battles it's about how you use your powers, and not just over powering your opponents. This is because I find it makes for more exciting fights and more realism in my writing.
Prologue
This world is a bizarre place, with things like [FATE] that cannot be changed, and [GRAVITY] that brings people together coexisting. There are mysteries left unsolved and stories untold, fading away into obscurity before they take hold. The [WORLD] has been changed by an endless loop mixing past and future together into an unrecognizable form with infinite potential. It closely resembled the original [WORLD] that was long lost, some could argue that it was the original brought back to take it's rightful place. The story begins in the Year 1989 and an event that will decide the [FATE] of the entire [WORLD] is about to take place. Unfortunately for this [WORLD] that will be delayed, but for another it means salvation. For in this [WORLD] lies an individual that has the power to alter [FATE] itself, the 7th [STAND] user.
Cairo, Egypt
Year 1989, Jan.15
Several men are [STANDING] in front of an old extravagant three-story mansion made of terracotta, it is surrounded by a wall and an extensive garden which includes numerous palm trees and other exotic plants, and with four towers on each corner of the rectangular main building. [LURKING] within is an ancient evil that is over a century old that these men have come to vanquish. One of these men is a tall extremely muscular high schooler named Jotaro Kujo, he is 195 cm tall and wearing modified trench coat-length school uniform with a tall, stiff collar, pierced on the left with a golden chain. Underneath, he wears a fitted, sleeveless shirt and a pair of slim-fitting pants of very short, sharp flares held up by two thin belts, often differently colored, patterned in a row of alternately colored tessellated triangles. He also wears a pair of leather shoes. An iconic cap sits atop his head adorned near the center with a golden button and, on its left, a rectangular golden plate with a design of a flattened hand.
[STANDING] right beside him are his allies on this dangerous journey. The oldest of the group being just as tall as Jotaro is his own grandfather Joseph Joestar, he wears a fedora; a light, short-sleeved, buttonless shirt; khaki pants; dress shoes; and white gloves with dark wristbands. He overall looks similar to Indiana Jones.
There is the silver haired French man clocking in 185 cm in a fitted black tube top, shoulderless except for one strap running from his chest over his left shoulder. He also wears a pair of light trousers with pouches tied to the belt on each of his hips. This was the ever noble Jean Pierre Polnareff.
Next to him the Egyptian man [STANDING] at 188 cm, who's attire consists of a robe with elbow-length sleeves and a scarf around his neck. He has two identical scars that run down his cheeks. He wears a headband or headscarf wrapped around his forehead and keeps his hair in a style resembling Bantu knots, as well as wearing a long ponytail. He wears earrings comprised of a single, long chain of medallions, resembling a necklace. The largest of these medallions is engraved with the Egyptian ankh symbol; a large tassel hangs from this medallion, resting atop his chest. The smaller medallions are engraved with various other symbols. He wears a varying number of thick metallic bracelets on both of his wrists. The wise fortuneteller Muhammad Avdol was sternly looking at the door of the mansion waiting for any activity.
Infront of them is a small, black and white Boston terrier dog who had a height of 33 cm. In another time he would have been missing a leg in the battle against Pet Shop an dangerous bird [STAND] user, but thanks to the intervention of his fellow crusader he was able to escape dismemberment.
Next is another high school student, a young man of above-average height of 178 cm and fit to slender build and red hair. He is wearing a slim-fitting long green high school uniform and cherry shaped earrings. His eyes hidden by a pair of sunglasses held two thin scars vertically crossing both eyes. His name is Noriaki Kakyoin who was joining backup with the group after getting out of the hospital.
Finally the last crusader is an average Japanese high school teen. He has an athletic build, gained from rigorous training and fighting on their journey, and height of 180 cm. The boy wears a bluish black school uniform and purplish-red t-shirt. This was Senbun Otomine, or Seven as his friends call him, the seventh [STAND] user of the group.
These men were on a mission to end an evil that plagued the Joestar family and save the life of Holly Joestar. Holly was being plagued by her own [STAND] and unless they defeated the evil in fifty days she would die.
That evil that was the undead monster that was DIO. Originally DIO was Dio Brando who was adopted into the Joestar family, but in an attempt to take the fortune for himself Dio became a [VAMPIRE] and battled his brother Jonathan Joestar. The two would continue this fight until Dio was left a head and killed Jonathan and took his body. Unfortunately for DIO he was sunken to the bottom of the ocean within a coffin of his own design, until a century later a group of fished his coffin from the sea floor. After killing the crew he obtained a [STAND] and gathered many allies in his goal of global domination. After beating nearly all of DIO's servants the crusaders standing in front of his mansion prepare to face the final battle ahead. Joseph eyes full of determination turns to his allies with a question.
Joseph: So shall we head in?
Senbun contemplates the situation for a moment, he was skeptical of the ease of entering the mansion. Not wanting to take an unnecessary risk Senbun addresses Joseph.
Senbun: Wait a minute Mister Joestar!
This causes the rest of the group to pause and turn to him. Advol perplexed by Senbun's outburst asks the boy.
Advol: What is it Seven?
Collecting himself Senbun explains his reason for stopping them.
Senbun: I know we only have five days left, but even so we can't rush things like this.
Confused by the sudden hesitation Polnareff voices his counter argument to his friend.
Polnareff: What are you talking about Seven!? DIO's mansion is right in our sight and we have the element of surprise! If we strike now we can finally end this!
The high schooler takes a small look at Iggy and attempts to further elaborate his reasoning to his allies by providing the facts.
Senbun: Remember Polnareff, DIO is a vampire and it's almost nighttime. We would just be giving him more room to fight, and Iggy and I are still sore from battling that bird. Besides I have a feeling DIO already knows that we defeated his guard, why else would the front gate be unlocked!
Understanding what Senbun was saying Kakyoin placing his hand on his chin and closes his eyes.
Kakyoin: I see, so our best course of action would be to rest up and strike at the first crack of dawn.
Tilting his hat and covering his eyes Jotaro says his catchphrase.
Jotaro: Yare Yare Daze, we just be walking into another one of DIO's traps.
With everyone having been assessed the risks in attacking Joseph decides they will go back and prepare.
Joseph: Alright lets wait till tomorrow, there is no such thing as too prepared when it comes to DIO.
The group nods their heads at Joseph's declaration as they head back to the hotel.
Later That Night
After returning to the hotel the group decided to stay in groups of incase DIO might send anyone after them. Senbun was bunking with Jotaro and Kakyoin tonight. As he sat on the edge of his bed polishing the sword he received from his friend Utah when they first met his roommates enter and Kakyoin remarks.
Kakyoin: Still polishing that sword I see.
Senbun nods his head at the statement and stops polishing the blade to speak to his friends. Jotaro looks at the sword and turns to his friend with a question.
Jotaro: Yare Yare Daze, you sure you'll be able to handle it Seven? Last time you used it almost sent you flying into a cliffside.
Despite all his progress Senbun has made all the way he could handle the full force of the sword. His first most attempt was when they were battling against a strange man who had summoned empowered versions all of their previously defeated enemies, after long rush of battling both Jotaro and Senbun had grown tired. Wishing to end it quickly Senbun drew the sword and destroyed the all the remaining [STANDS], but sent him into the air and he was out of commission for a day. His second time with the sword he had to use his [STAND] to wield the power.
Senbun: I appreciate the concern guys I really do, but the Sword of St. George could really help us out against DIO. Besides I think I'm making progress with it, all I have to do is drape Sonic Youth over me like an armor.
Kakyoin raise an eyebrow at the name and asks.
Kakyoin: St. George? You said this Utah's his family got this sword from St. George?
Senbun raises his hands motioning for his friend to slow down so he could explain.
Senbun: No, no! You see Utah's family meet a man named George and from what he told me the man was very noble and generous. So I decided on naming it in honor of kindness.
This answer caused both of his friends to smile at him, which lead to Senbun scratching the back of his head. After the discussion of the sword and it's history was done Jotaro sighs and puts his both hands in his pockets and Kakyoin asks with a serious expression.
Kakyoin: So this is it? Seems so surreal and yet foreboding to be so close to DIO. I fear as the paranoia of being attacked will put me on edge for the entire night.
Jotaro looking slightly annoyed at the way conversation was going and proclaims with voice calm.
Jotaro: Quit it with the drama already, we will beat the shitty bastard.
Smirking with gusto Senbun crosses his arms on his chest and happily agrees with his tall friend.
Senbun: JoJo is right Kakyoin we just have to give it everything we got!
Laughing lightly Kakyoin stands proudly.
Kakyoin: Believe me I don't intend to hold back, not even a single bit. We can't afford to lose here for Miss Holly sake and the world.
The three high schoolers smile as display their confidence in themselves. The crusaders continue to talk for sometime before they head off to bed. As they were midway through discussing dreams Jotaro notice something was off. It wasn't long before Senbun and Kakyoin both felt the off putting presence in the room too. Jotaro looks around to see what was the cause and spotted their luggage sinking into ground he tried to warning the two, but by then it was too late. The three struggled trying to get free and as they looked around the floor began to shift into a whirling vortex of dark colors slowly swallowing all the furniture and anything else on the ground.
Kakyoin: It's pulling us in the more and more! Is this a [STAND] or it's ability!?
Trying to figure out the strange [PHENOMA] Senbun asks aggravated as he attempts to escape from the sinking floor while looking for anything that was causing this.
Senbun: If so where's the user!? We're on the 5th floor so are they above or below us!?
The third JoJo grits his teeth in frustration at their inability to get free and calls upon his [STAND] for help.
Jotaro: Damn It! Star Platinum!
As the [STAND] emerged from his user he punches the ceiling creating several holes for him and his friends can to latch onto. Picking up on what Jotaro had planned Senbun and Kakyoin follow his lead summoning their [STANDS] to pull them up while they hold onto the ledges. Their [STANDS] pulled them up with all their might with Kakyoin turning Hierophant Green into a make shift ladder for his friends to climb, while Senbun used Sonic Youth to create wind currents that pushed them upward. As they made little progress in escaping the vortex, the force increased twice over and continue to do so.
Senbun: We won't be able to escape if this thing gets any stronger!
Struggling they continue to hold on for dear life. Taking it's toll Kakyoin gives an rundown of their predicament.
Kakyoin: My Hierophant can't hold out for long. Trying to withstand the force and keep us from sinking further is becoming increasingly difficult! If this keeps up my [STAND] will be ripped in pieces! We must leave the room immediately, Jotaro destroy the wall it's our only hope!
Jotaro grunts frustrated by the ever increasing vortex reasons against this course of action.
Jotaro: We know next to nothing about this thing for all we know it could already have affected the entire floor. Even if try to smash the wall to the outside with Star Platinum this thing will just suck in my [STAND] the moment I do.
The trio grew more and more worried by the second. Suddenly before they could react the walls begin to break away causing Hierophant to lose it's holding. This left the three falling desperately attempting to find something to hold onto. Unfortunately there was nothing left for them to grab hold and they begin to be consumed by the vortex once again. They thought that this might possibly be the end of the line and yet the didn't give up hope. Still fighting on against the vortex until the very end. Soon enough they were gone, but this the end of the [STORY], in fact it's just the beginning of another [STORY] a small break if you will. For those who [STAND] proud never truly are gone, just somewhere else.
