Hello everyone! Back at it again with another project. I actually have a lot if this planned out but can't promise if this will be a long story with many chapters or just this chapter. But I wanted to publish something and put a lot of time into this. So hope you enjoy regardless!

This is an AU using a mixture of Star Vs and Persona 5, as the two mingle together a lot better than one might realize.

Rain splashed against the cold walls of the Echo Creek Police station, with a young woman sighing, fixing the hold of her umbrella as she looked over a case file. Closing it as fast as she opened it, she closed her umbrella and harshly pushed open the doors. Various co-workers tried greeting her, but cold blue eyes glazed with rage simply pinned them all in place.

"Why can't I see him?!" A familiar voice shouted, with the woman pausing at the sight of the blond girl, not much younger than herself. She frowned harshly, trying to use her long blue hair to mask her worried expression.

"He's a suspect and you are breaking the rules! You knocked out two guards a moment ago, lucky your sister is in charge of this case or you would be joining him." The guard tried pushing the girl away from the door, but she refused to budge. "Moon, glad you are finally here. Get your pest away from the crime scene."

"Star…" Moon said softly, putting her umbrella down on a nearby bench and tried reaching out to her younger sister, but Star quickly turned around, slapping her hand away and having a mixture of emotions on her face. "I will take care of this, okay? Go home."

"But…" Moon simply hugged her sister, with Star relenting, seemingly at least. Letting go, Star slowly left the station with Moon just noticing her usual bright blue dress soaked from the rain. Turning back toward the guard, she took a deep breath and went inside the guarded door. Light creaked into the room, she saw the bruised and battered form of a young man. His cheeks were puffy, eyes bloodshot, and wrists clearly showing marks from his cuffs. But to her complete, or rather, lack of surprise… The boy had no expression on his face. He looked still.

"Hello, Moon." The boy started, his tone neutral. Moon frowned at this, but walked to her seat and sat down across from him. "...Before I say anything, Star stays out of this." HIs voice was laced with conviction, but Moon didn't respond, just sliding the case file over to the boy.

"Marco Diaz… I housed you for nearly a year, and…" She grit her teeth, angered emotions bubbling up. "How could you do all of this? And dragging my sister into your mess of all things." Marco narrowed his eyes, their brown complexion showing no ounce of guilt.

"You are acting like I killed people when I simply helped this city," Marco replied, sitting back and eyes drifting to the cell bars. "The rain usually helps calm my mind, when things are so down like right now…" Moon just folded her arms together, wondering where Marco was going with this.

"I can't promise you anything, but if you comply, your allies won't get hurt and your time in juvey could be lessened," Moon stated, Marco's face having a thin line across it. "...And Star won't be in trouble. At all. I promise you as her sister."

"...You wouldn't even believe me if I said the complete truth." Marco laughed, hand covering his face and him wenching at his bruises. Moon reached out and held his free hand, giving it a firm squeeze. "...But you aren't like the other adults or older fellas. So maybe you might believe me."

"I'm willing to listen," Moon replied, with Marco closing his eyes, seemingly deep in thought. Moon just gave him time to collect himself, knowing this nearly a year and a half long case will be one heck of a story. Marco sighed and held the file in his hands.

"It all started back when I left my home in Fallen Peaks…"

The warm sunlight of Fallen Peaks welcomed Marco as he left his home. He scoffed at how 'friendly' his parents were to him, wishing him good luck on the trip to the grand city of Echo Creek and asking him to 'be a good boy'. As if I wasn't one before doing the 'wrong thing'. Marco spat in his mind, grip on his suitcase tight. Taking his time walking to the train station, he tuned out all onlookers gawking at him simply casually walked down favorite sidewalks filled with years of his footprints.

"Can't believe you're leaving this dump, wish I could join you," Marco turned to his right, seeing his 'favorite person' having her usual snarky smile. Janna Ordonia, childhood friend or as Marco referred to her 'annoying pest that is sometimes cool to talk with', has always kept an eye on him. "If it counts, I would have slugged that creep too."

"No, you would have hexed him, stole some snakes from the pet shop down the street and shoved them in his pants," Marco smirked, Janna elbowing him in response. The two walked in silence for a few minutes, Marco wondering if anyone would miss him. Granted, he wasn't the most popular kid in town, but he at least hoped Sensei and Oskar would miss him. Pausing his walking, his eyes drifted toward train tracks. Did I walk here that quickly? He turned to his left, and whistled, seeing his train coming into the station. Janna stood next to him, holding out a book. "What's that?" Marco asked, with Janna nearly throwing it at him.

"It's my book of spells. Use it to mess jerks up for me," Janna held out her fist, with Marco holding his out for a fist bump… Only for her to harshly punch his arm. "See you around dork." Marco watched as Janna ran off to do whatever. Smiling at the mental image of her pulling her usual pranks on a new sucker… victim, made Marco realize there was a bright side to leaving this town.

Fixing his hold on the suitcase and book, Marco went into the train and found his seat, pleased to find one for once. Fallen Peaks usually is more of a 'small town' than a major city, but Marco remembers trying to head out to Echo Creek with Janna and her that one time. Sighing at how great that escapade turned out, he flipped through the book Janan gave him and tuned out the world.

To Marco's surprise, the book wasn't a spell book at all, but rather it was one about spirits. He flipped through it, seeing the various image of ghostly-figures linked with different 'signs'. Arcana? I guess that's an element of some kind. Marco figured. Years of gaming and watching anime helped him get this picture somewhat. Turning the next few pages, Marco found a page discussing something called 'Wild Card'.

Reading the page, it read:

The Wild Card is a being that cannel multiple masks, hiding from the world around them while also embracing the true natures within us all. Forging bonds and connections enhance this power and make one the joker of any deck.

"How does this relate to spirits?" Marco asked aloud, scratching his head in confusion. People around him on the train gave Marco dirty looks, making the boy mouth 'sorry' before they ignored him like before. "Maybe Janna stole this from someone…" Marco mumbled before putting the book into his suitcase.

His brown eyes drifted to the window, seeing the train slowly bring Echo Creek City into view. Marco's eyes went wide, amazed at how huge this place was. Billboards advertising movies and games, people clustering around massive city blocks like organized ant colonies, and specific energy emitting from the city. Something Marco couldn't put his finger on…

The train stopping caught Marco out of his thoughts, standing up and rushing out to avoid being trampled. Seeing the city's center building, he couldn't help but gawk at how tall it was. Fixing his hold on his suitcase, Marco took a step forward but bumped into someone. "Sorry sir, I didn't…" But Marco didn't hear an insult as he expected. Everyone stood still, like statues, even the flying birds were frozen in the air.

So you are ready…

Marco jumped at the voice, it sounding like a demon wanting something from him.

You need motivation, but the time will come soon.

A blue butterfly slowly came into Marco's view, landing in his open palm.

Great power is within you, unleash your inner self.

The butterfly exploded, causing Marco to fall to the ground and the ghostly figure of a man in a top hat greeting him, before vanishing in an instant. "W-What the heck was that?!" Marco shouted, but he was harshly kicked by someone behind him. "Sorry, sorry!" Marco shook off both his newfound pain and annoyance, rushing to the address his parent told him about.

The busy streets of Echo Creek confounded Marco, with the many roads forking into various paths. It's like I'm a mouse in a maze. He thought in good humor. Looking around, he didn't see the usual frowns and glares aimed at him unlike how things were back home. He was another fish in the endless ocean around him. Like it should be. His eyes darted around however, wondering just where this apartment was. It was by the police station…

"Get back here!" Marco jumped at the sound of an angry policewoman with blue hair rushing toward him. Rolling toward the nearest alleyway, he avoided her line of vision, worried about getting in trouble again for doing nothing. Peeking his head out from the corner, he just felt confused at the sight. It was a boy around his age, wearing a red headband on his forehead and having odd horned armbands on his torn-up school uniform. "My sister doesn't want to see your face, Thomas." Her voice was icy cold, making Marco shiver. Please don't let that be the person taking me in. He begged in his mind.

"I was just saying hello!" Thomas shouted back, his voice not thuggish as Marco expected. "She is my friend." The woman just glared at Thomas, the boy's confident resolve shrinking every second she kept her glare going. "...I-I'll leave. Sorry Moon." The boy ran off, with a mess of blond hair coming out of the building behind Moon. Marco blinked at the sight of the girl. Wearing a bright blue dress with a narwhal of all things at its hem, she had a denim jacket with various pink hearts on its sleeves on as well. The thing that stood out to Marco was her odd-colored leggings and tall purple boots. She's really pretty, guessing that guy was her ex or something. Marco figured, his vision lingering on the girl. Her blue eyes turned toward Marco, pinning him in place. Shit, she saw me!

"What is it?" Moon asked, getting the girls attention. She pointed to the alleyway, with Moon taking out a taser from her jacket. "Come out, I have a permit." Marco walked out of the alleyway, hands in the air. "...Wait, that mole. Are you one of the Diaz's?"

"Y-Yes ma'am," Marco said shakily. He slowly walked toward Moon, hands still in the air and people watching him. Great, everyone knows I'm a problem child now. Ugh… "Is this the right a-address?" Marco handed Moon the address slip his parents gave him, the woman looking it over.

"Sis, stop scaring him." The girl stated, taking the taser and shoving it into her pocket. "Hello! Name's Star." She held out her hand, having an inviting smile on her face. Marco relaxed somewhat, shaking Star's hand and proceed to have his arm nearly dislocated. Finishing the handshake, Star dragged Marco into the house as Moon watched the two of them with a baffled expression. Being tossed into the couch, Marco groaned in pain. Looking at his right hand, he was surprised at still holding his suitcase. Moon walked into the door, folding her arms and giving Star an expression screaming 'let me talk to him'. Star pouted in annoyance but walked up to the nearby set of stairs regardless.

"I-I promise to not do anything," Marco started, fear coursing through his body. Moon blinked, a warm smile present on her face. "Y-You likely heard from my dad about…" Moon simply sat down on the couch, hands resting on her lap and eyes firmly locked on Marco.

"I know your situation, and understand that what you did, isn't something in your character," Moon said carefully, causing Marco to raise an eyebrow. "I only have you for a year Marco, until you are sent back home. And… I have a lot on my plate here, watching over my sister and ensuring our recent case goes well." Marco blinked, surprised at how open Moon was being toward him. There is a catch I'm guessing… Sensing Marco's thoughts, Moon sighed as she stood up. "If you can, keep an eye on my sister and keep out of trouble." She started walked toward the stairs, pausing and giving Marco a stern glare. "If you try anything with my sister, I will chase you out like that demon child."

"Yes ma'am, I mean Moon," Marco saluted, with Moon giving a small smile as she walked toward her room seemingly. Letting out a held breath, Marco looked around his new home for the year, surprised at how different it felt compared to his home. Getting out of his seat, he took in the living room's blue walls and cool colors, a stark contrast to how bright his home's walls were painted. Driving his vision toward a picture nearby, Marco picked it up. It was of his family of all things, posing with a younger Moon holding a baby version of Star. To his surprise, he saw another woman standing between the two of them, her warm smile nearly matching his mothers.

Putting picture down, he formed a thin line on his lips. So… I get it. Marco rubbed his arm, looking toward the stairs in front of him. Picking up his suitcase, Marco slowly walked up to the stairs and looked around for his room. As he was looking around for more information on his new 'family', he heard a loud bark, making him jump in the air. He entered combative stance, something Sensei drilled into his skull whenever danger was around… But his eyes drifted toward the small black pug studying him. "Huh… Hello, doggie." Marco bent down, holding out his hand. The pug slowly walked over toward it, sniffing his hand before his aggressive eyes turned friendly. "Didn't mean to bump into you. You are kinda small pal."

"Watch where you're going next time champ," He heard the dog say… What? Marco blinked, his free hand lightly slapping his cheek to wake up from this seeming delusion. But he only saw the dog bark again. ...I need to sleep. He pet the puppy again before going into the empty room down the hall. The puppy followed Marco, his beady eyes studying as he flopped on the bed and groaned in exhaustion. Hopping on the free spot in the bed, the puppy huddled between Marco's arms and closed its eyes. "Night talking doggie."

Unaware to the booth of them, Star was watching through a crack in the doorframe. Slowly coming inside, she held up a finger to her lips, telling the puppy to go back to sleep. Finding a nearby sheet, she covered Marco and gave a warm smile before leaving the room, slowly closing the door.

"Wake up inmate!" A loud voice shrieked, making Marco jump out of his new bed… Which was oddly metal for whatever reason. Rubbing his head, he groaned as he got out of bed, but his eyes dilated at the sight of chains on his arms. As his vision trailed down his person, he saw a torn up stripped uniform, not unlike…

"Why am I in juvie?! I served my time already!" Marco shouted, anger coursing through his person. He marched to the bars in front of him, hands clenching the metal bars as part of him wondered if he could pull them apart. A knowing laugh got his attention though, Marco's eyes drifting to a blue man sitting behind a desk. His nose was pointy, though that was the least 'odd' thing about the man. Long ears like an elf, yellow-ish business suit covering his short body and even an odd pink gem on his forehead stood out like a sore thumb. Marco was going to shout at the man for putting him here but a shock coursed through his body. He fell on his knees, gritting his teeth in pain.

A hooded figure in blue stood before him, holding out some kind of teaser object. "Don't disrespect your master or you will be punished insect." The hooded figure uttered. Female warden? Usually, the juvie has male wardens and guards. Marco forced himself up, trying to stand tall and hoping this nightmare will pass. Seeing Marco's calmer posture and expression, the hooded figure scoffed and turned toward her 'master'.

"You will be familiar with me in due time, but just wanted to introduce myself before the game can begin," The blue man started, a smile worming across his small face. "I am the owner of this Velvet Room, known by many as Glossaryck of the Arcana. But that's not important." He waved his hand casually, making Marco raise an eyebrow.

"...So this isn't prison or juvie?" Marco asked, with Glossaryck simply smiling in response. "Well, what is your deal then? Is this some kind of fever dream? A dog DID talk to me before I went to sleep."

Simply clasping his hands, Glossaryck leaned forward, causing the hooded figure to walk toward him. "Kindly give our guest a key, he is going to need it. Or not, who knows. He has to wake up first."

The hooded figure simply threw it at Marco like a baseball, Marco ducking as the key bounced off the wall behind him. "You trying to take my eye out?!" Marco shouted, but the hooded figure laughed like a trickster or something. Marco huffed in annoyance, walking toward the blue key and picking it up. "This feels… Powerful." Marco walked toward the cell bars, opening his mouth about to ask something. But a sudden sensation of tiredness came over him, making Marco fall on the ground and pass out cold. The last things he heard were something about a wild card…

"Why did we take him in sis?" Star asked, munching on some eggs and toast that Moon was kind enough to make. Moon simply sipped from her coffee mug, mind invested in papers neatly scattered across her end of the table. Star pouted, this happening often the past three years. Come on sis… Star thought in annoyance, lightly kicking her sister's heeled legs. Moon made a slight jump, blinking at Star's action. "You know you can't ignore me."

"We took Marco in because his family is good friends of ours, you know this Star," Moon closed her case file, leaning forward and raising an eyebrow. "But… He needs a second chance, and I'm willing to give that if he behaves." Moon leaned back into her chair, having another sip of her coffee. "If he gets in trouble, it's on you."

"What? Come on, don't be 'mom' again," Star folded her arms, with Moon giving a weak smirk in response. "We won't get in trouble… I don't even know him yet."

"Yet, once you become friends with him, I'm sure you will be tempted into going through that 'rebellious' phase again." Star gave a genuine frown, with Moon having a worried look in response. "Star, your grades suffered from all that goofing around. We can't…"

"Yeah, I get it. Be the boring good girl and what not. Guess that's why you keep kicking Tom out whenever he says hi." Star spat, clearing off her plate and rushing out of the kitchen. Star bit her lip in self-frustration, but she couldn't help herself. I am trying sis… If only you saw that sometimes. Star rubbed her arm, eyes drifting to toward the stairs. Guess sleeping handsome better wake up soon. Rushing up the stairs, she kicked open Marco's door, hoping to surprise him… But she found a neat room and a shirtless Marco trying to put on his school uniform. "Uh… H-Hi."

"...Hi?" Marco said dully, continuing to put on his shirt and ignoring Star's bright red face. H-He has abs? Star quickly patted her cheeks, calming down the odd nervousness coming over her. "Sorry if I grossed you out or anything. But knock next time, okay?"

"Yeah, no prob," Star swayed back and forth in place, blue eyes studying Marco getting his thing together. "You know, sis made some grub for us." Marco smiled, holding up some food of his own.

"I didn't want to bother you guys. Besides, brought some food from home. Mom makes some good sandwiches." Marco sat down in his desk chair, one that Star remembered… No, this is the guest room, not her room. "...Are you okay? Got quiet for a sec there."

"Just thinking about how fun it will be to show you around town!" Star replied, her warm tone making Marco send a warm smile back in response. "I'll be ready to head out in a bit, so don't leave without me buster."

"Sure thing." Marco made a mock salute, with Star giggling and leaving the room. He seems cool. Star smiled at the thought, thinking a great friendship would blossom.

Hope you enjoyed this and I will likely be back with another chapter sometime next week, so stay tuned :).
