And now, after this one-shot, I finally finished making a trinity of crossovers between my 3 favorite fandoms during these past months: Persona 5, Code Geass, and Fire Emblem Three Houses. Kinda.

I'm still working on the P5xFE3H chaptered story!

We're Thieves, Not Assassins

Lelouch vi Britannia stood impassively over his brother, the Viceroy of Area 11, aiming a gun to his head.

"It wasn't me! I promise! I didn't kill her! I didn't have her killed!

"I understand," Lelouch lowered his gun for a moment "However…" He smiled and lifted the gun back up. The gun felt so light in his hands. It felt as if the trigger could be pressed with a single tap. He felt so powerful as he held his brother at his mercy.

Clovis pleaded, "No, don't! We may have different mothers, but I'm still your brother!" His hands shook as he begged his younger brother to spare him.

"You can't change the world without getting your hands dirty." The eleventh prince stared uncaringly into his brother's eyes.

He pressed the trigger.

.

It was silent. The gun had a built-in silencer and Lelouch only slightly grimaced at his brother's body. The brother he once loved to play chess with was now no one important. He held no love for Clovis anymore—not when he orders the mass killings of innocent people in Shinjuku and caused Suzaku to die. The Black Prince turned his back to the body.

"My my… leaving so soon?" A deep voice echoed from the shadows of the darkened Viceroy's room.

Hearing the intruder, Lelouch lifted up his gun, unsure where the voice came from. He furrowed his brow and frowned as his face was exposed and he didn't how much this intruder heard.

"Show yourself!" He shouted to the shadows.

"Sucks that we were a bit too late but that was pretty cool man. You just went bang bang once and now Area 11 is free of one stupid prince." A male voice cackled as he made gunshot sounds. "Too bad he'll just be replaced by an even shittier one though."

"Ah yes, I agree."

There was a mock gasp followed by a feminine voice. "Crow agreeing with Skull? What has the world come to now?"

There was a distinct tsk sounding like someone was clicking his or her tongue. "I'm merely impressed that he could find his way through the Viceroy Palace so easily and kill Clovis."

"I, too, have to agree." A black figure stepped out of the shadow. His voice was the same as the first voice Lelouch heard. His clothes blended in seamlessly with the darkened room except for his white mask and red gloves now illuminated with a bit of light. "That was impressive… Lelouch."

The Black Prince flinched and pulled the trigger once again at the man but he evaded it easily.

"Woah, trigger happy much?" The black-clad man chuckled.

"Stop agitating him Joker," another feminine voice exasperatedly called out.

"His aim isn't any good anyway," the man, who Lelouch knew now as Joker, shrugged his shoulders.

Lelouch kept his gun aimed at the man, willing to shoot multiple bullets at once if needed. His aim wasn't great, but he still had several bullets left in the gun.

"Tell me," Lelouch narrowed his eyes and turned on his Geass. "who are you?"

"Whadya say. Should we tell him?" A man spoke from the shadows.

Joker didn't say anything and Lelouch cursed inwardly. It seemed that these masks covered their eyes so the Geass wouldn't work.

"I say no," A girl's voice rang out. "We know who this guy is anyways. Lelouch vi Britannia, the Eleventh prince of Britannia, said to be killed eight years ago during the Japanese invasion."

The Black Prince hesitated but didn't pull the trigger again yet. He didn't know how many of them were still hiding behind the shadows. He cursed inwardly again, angry that his perfect disguise as a regular Britannian student was now compromised. Would these people kill him? They were here to kill Clovis but if they haven't killed him yet, there might be a chance for Lelouch to work with the group.

"What should we do with him?"

"Kidnap him!" After no response from her coworkers, the voice's owner cried out, "What? He saw us and we can make use of him somehow."

"Where would we even put him?"

"If you want, we can put him in my house!" Another new feminine voice chirped up from the shadows.

Oh god, how many of them are there? Lelouch thought.

"Which one, Noir?" Joker asked, but quickly stopped the girl from commenting any further. "I'm just kidding. We're not going to compromise any of our locations. We'll just keep a good eye on the Highness right here," the masked man looked to Lelouch. "Don't meddle too much in our work and we'll leave you alone. Got it, Princeling?"

He didn't even know who these people were or their work. They sounded like...assassins? Lelouch narrowed his eyes in frustration but nodded hesitantly.

"Then tell me, who are you? So I can stay out of your business." Lelouch asked.

"We are the Phantom Thieves."

Much like how he appeared, the man disappeared into the shadows.

.

Phantom Thieves. The world's most infamous and powerful assassins. Lelouch shuddered at the thought that the men and women he met were truly these notorious killers that could have killed him so easily. They left no traces of entering or leaving the Viceroy's Palace, much like their other jobs around the globe. After a job, they left a calling card in the victim's room and posted the calling card on their website soon after the job.

Lelouch looked at the search results on his computer notebook again.

Their activities started about two years ago. They had a website that was accessible from every single country or Area in the world. Whatever methods the governments or superpowers tried to use to ban their website was thwarted too easily. After a year of trying to hack the website and make it close down, all governments just seemingly gave up. There were many rumors that the Phantom Thieves forced governments to back off though.

Because the comments were anonymous, there were plenty of requests for someone or another to be assassinated, but the Phantom Thieves chose the targets themselves. The website was mainly their personal forum to post their calling cards.

Lelouch looked at a map that showed all the places that the Phantom Thieves targeted, compiled by a fan of these assassins. It was morbid to see that these killers had so many fans, but their sense of justice resonated with many frustrated people. There were hundreds of places around the globe that were marked with a red dot.

How was it even possible that they travel the world so easily? Was the group he saw in the Viceroy's Palace just one group of many around the globe? How did that even work?

This was more frustrating than the situation in Shinjuku. They better not intrude on his own plans. He would find ways to beat them. Lelouch grit his teeth and slammed down the computer screen.

"A-are you okay, Lelouch? Is something wrong?" Shirley, who was sitting in the table of the Student Council room working on her homework asked worriedly.

"No Shirley," Lelouch looked to her and gave a fake grin. "Just a bit annoyed that a chess match I planned to have with this rich noble fell through."

"Geez," Shirley frowned. "You were annoyed about that? I told you to stop gambling!" She chastised.

Lelouch held his arms up in defeat but didn't say anything.

.

"Dammit, Prince vi Britannia. Why do you keep killing the people I'm trying to kill? That makes it no fun." The Phantom Thief in the white mask, Joker, appeared out of the shadows in the hotel room filled with the dead bodies of Kusakabe and his men. He looked at the fallen bodies and his body screamed disappointment.

"Do you ever think that it is perhaps your fault that you are too late?" Zero replied with slight apprehension.

"Mona took too long to finish his tuna."

A small, boyish outcry of hey rang out from the shadows. Lelouch ignored it for the moment.

"Anyways we don't appreciate you killing our targets. I thought we warned you last time."

"I don't even know who your targets are, Phantom Thief. How do you assassinate people all around the world?"

Joker shrugged. "We have our methods, as do you."

And he disappeared into the shadows.

.

"Thank god you left my targets for me to take this time, Prince." The Thief was sitting on a sofa couch, admiring his gun as Lelouch, dressed up as Zero, walked into the room. Lelouch could almost disregard the bodies of two Britannian nobles laying face down on the ground.

Lelouch flinched at the title and he was glad none of his Black Knights were around to hear the Phantom Thief's little quip.

"Don't call me that. Call me Zero. Are your friends around again?"

"No, they're doing their own thing. We don't have to send everyone to kill just a few nobles. Then there will be less than one body per person." The Phantom Thief hummed. "Oh and also did you ever get my name?"

When Lelouch didn't respond, because he wasn't sure if he should, the Phantom Thief opened his mouth again.

"Call me Joker. Leader of the Phantom Thieves. Hopefully, we don't see each other again."

And he disappeared once again.

.

Lelouch pointed his gun at Euphemia as tears escaped his eyes. This was his fault—his mess. He had to be the one to have the death of his sister on his hands.

Euphemia, knowing that Zero wasn't Japanese lowered her gun at him. She gave such a brilliant smile while she was covered in the blood of those she killed.

As more tears fell down his eyes, Lelouch pulled the trigger.

But the bullet didn't hit her.

"I told you. You have terrible aim."

For the first time, Lelouch saw the black-clad man clearly as the sunlight brightened the black outfit. Under the white mask and messy black hair, the man smirked confidently as the sunlight put a spotlight on him.

Euphemia was held in the arms of the Phantom Thief who magically appeared and was hanging off a rope. Lelouch's eyes followed up the rope and saw a flying Knightmare that looked strangely like a cat. How was it even flying?

"Again, why do you try to kill all my targets," Joker sighed as he ignored Euphemia's question if he was a Japanese or not.

"I…" Lelouch didn't want to kill Euphemia. But she would never stop her genocide unless she was dead. "But you saved your target this time. Why?"

"She's not. She's dead." He stabbed a needle into her neck and Euphemia slumped down lifelessly. The rope started pulling him up toward the Knightmare.

Lelouch jumped into his Knightmare to kill the Phantom Thief as well as the Massacre Princess if she was still alive.

But before Lelouch's cannons could reach the two, the pair vanished into thin air and was replaced by a flutter of cards falling to the ground.

.

Princess Euphemia li Britannia,

The harbinger of peace. You have committed the grave sin of wanting peace in a cruel and destructive world. We know your desires are too big for the world to comply.

We have seen your demeanor change after speaking with Zero, changing your cognition and your free will. We have decided to steal your distorted cognition and take you from this world.

From,

The Phantom Thieves of Hearts

.

"What a surprise. You're here earlier than I am this time. I thought you didn't want to see me." Lelouch said in a deadpan expression, hiding his weariness at meeting the man that he hadn't seen in over a year.

The Phantom Thief that appeared in front of Lelouch one too many times was lying on his bed and twirling a knife between his fingers. He looked defenseless, even with his knife in his hands, but Lelouch knew that the man could easily dodge any bullets he shot at the man.

"Yeah yeah, long time no see to you too." The Thief rolled in the bed, mirroring the witch's actions too closely for Lelouch's liking. "I only came because you're the target this time."

The Black Prince froze in place, but he did expect it somewhat.

"I'm still debating whether or not I should kill you. We'll see after we talk."

"I thought assassins move in the dark, making sure that their targets don't even know that they are at risk dying.

The Phantom Thief groaned."Why do people think we're assassins? We're thieves, not assassins." He grumbled. "You know we're named the Phantom Thieves, right? Thieves. We steal. We steal people's hearts." The Thief childishly huffed and rolled to his side, turning his back to Lelouch.

"Literally, or metaphorically?"

The Thief lifted his head to look at the Prince and grinned maniacally.

"Both."

.

There was just only chaos. One minute, the Prince Odysseus the First Prince of Britannia was standing on the altar of a Britannian style chapel, ready to marry the Tianzi; the next minute, he fell onto his back with blood spurting out of his chest.

There was screaming from the young Tianzi who was covered in the blood of her soon-to-be-husband.

Ah, the late soon-to-be-husband.

The Britannians started shouting accusations, but on one swift, fluid motion, a red light passed by every Chinese Eunuch and they too dropped dead.

All members in the wedding hall stopped as red and black cards sporting a logo of a red top hat fell from the ceiling.

.

"Tell me, Mr. Intruder, what should we call you?" Schneizel said as he sat on top of a throne in the Damocles. As soon as he dealt with the intruder, he would leave the Damocles so that Lelouch would fly into the atmosphere, stuck in the flying fortress until it was burned by the sun.

The White Prince's faithful aide de camp Earl Kanon Maldini reached for his gun and held it up to the shadows, even though he couldn't see the intruder yet.

A man stepped out of the shadow. "You can call me Joker. I am the leader of the Phantom Thieves."

"The Phantom Thieves' leader? How interesting. No one who had seen you in person has lived to tell the tale. Tell me, how did you manage to board the Damocles? And why expose yourself to me if you are trying to kill me?"

"I walked through the front doors. You should make sure to close it properly. Also, plenty of people have seen me and know me as a Phantom Thief. A few are still alive."

There was no way for someone to simply walk through the front doors. Schneizel's frown grew even further.

"Why are you here?"

"Just here to give you a parting gift."

A card manifested in Schneizel's right hand magically.

It read:

Prince Schneizel el Britannia,

The Prince of Destruction.

You have committed the grave sin of mass destruction and death in the name of false world peace. You have colluded with enemies to bring down a man that is able to bring actual world peace. For this, your life, as well as your allies, will be forfeit.

Signed,

The Phantom Thieves of Hearts

"Isn't this a bit hypocritical?" Schneizel gripped the calling card. "From my understanding, you and your group have killed many people as well."

"Ah, but we know the names of who we kill. We know their sins personally."

"Who are you to pass judgment on people? The men, women, and children who died have died for peace."

"And who are you to wipe the blood of those killed off your hands and into the hands of a blind, crippled girl?"

The Thief took out a knife and started twirling it around his fingers gracefully.

"I'm a single person but I represent the Phantom Thieves. So let me tell you this. We're Japanese. But we don't care about Japan. We don't care about Britannia. We don't care about the world's morals. What we do is simply because we believe in our own sense of justice. We pass judgment because we can. We're killing the corrupt and evil one bug at a time. In three years, we killed over half of the corrupt leaders in the world. You kill in the name of false peace that will never last. We kill in the name of our own righteousness. And you know what? I don't hear the masses complaining about our work."

"You're delusional. Are you under Lelouch's Geass?"

Joker laughed.

"The Geass is not the only supernatural power in the world. Another supernatural power was created because of the twisted, distorted desires of humans. And you have a Palace of desire that is the size of the whole world. You are the one who is delusional."

Schneizel cocked his head and his aide de camp pulled the trigger on his gun as well as the guns mounted on the walls. The mounted guns weren't the best at locking on targets so much of the ground around the man was destroyed, making a small dust cloud.

Although he couldn't see the body anymore, Kanon knew that his shot was the first to reach the Phantom Thief as he saw the bullet meeting the Thief's forehead and the man falling to his knees. He put his pistol away back into his coat.

"You certainly are a good shot. Lelouch should have gotten shooting lessons from you." The Phantom Thief's voice rang out from the throne Schneizel was sitting on.

The Second Prince's aide whipped his head to the throne and found the black-haired Thief sitting on the throne. His head then turned fearfully to the place the Thief was originally standing and he shook at the sight.

The White Prince's lifeless form was kneeling on the ground, a bullet hole decorating his forehead and his white coat painted by blood and holes from bullets.

.

"Even if your plan spectacularly fails, I'll have a good time cleaning out the trash left in the world."

"Do you actually enjoy killing?"

Who was he kidding. Lelouch already knew that the man who was sprawled carelessly on his gigantic bed lived to kill.

"Yeah. I like killing. I like about killing the corrupt the most. There's this small part in my brain that goes, 'Oh fuck yeah Joker. The world is a tiny bit better because of what you did.' I think that's my younger self's morals trying to desperately justify killing."

"You're insane."

"Thanks for the compliment."

Lelouch huffed and left before the man could even disappear.

.

"You're a terrible replacement." A voice rang out behind the new Zero.

Suzaku whipped around, not willing to let an enemy see his back. He took out a gun hidden in his Zero costume jacket.

"Who's there?" Suzaku yelled to the shadows as he pointed his gun.

"Just a person with a hostage you would like."

Suzaku opened his mouth to demand more answers but from the shadows emerged Euphemia who ran and tackled him with a hug.

"E-euphie?! I thought… I thought you were killed! Ah! Careful I have a gun in my hand." Suzaku dropped his gun and took off his mask after wrestling his hand out of Euphemia's crushing hug.

He looked at her again, making sure that she was real and not a dream.

"The calling card… Lelouch… Zero. I thought they killed you."

"But here I am!" She exclaimed in elated joy. "I'm not dead and I have a clear mind. I needed to stay away from the world because of the guilt I felt when I was able to break out of the Geass with the Phantom Thieves' help. But I'm better now. I'm not the same person you remember as but I'm here."

"Me too. I'm not the same person you knighted, but I'm here as well. Here for you." Suzaku gave a tearful smile.

"Thank you Suzaku!" Euphie gave a radiant smile.

She paused and lifted a finger to her chin into a thinking pose.

"If you're here for me, then will you come with me to my next heist?"

.

I was trying to make this serious and then I was like okay F it, my fingers are tired. I'm tired. Let's just make Akira/Ren/Protag a bit crazy in the head... (:
