A/N: Um, yeah, I've been working on this for a few weeks now, and it's obviously rocketed away from me. I'm ninety-some pages in, and that's technically the prequel. Anywayz, enjoy this, the very first Persona 3/4/Danny Phantom crossover! I win!

Warning—contains a bisexual polygamist!Minato. There will be mentions of boyxboy, but nothing more than kissing. Vague mentions of reaching level ten, for those of you who have played the game. ;P

Hey, so I added a few scenes. I'm actually going through this story to add some stuff in and fill some plot holes, so please read this again! It makes more sense now, and explains some of the Persona stuff, for those who've never played/heard of it!

"Did you hear? There's a new first-year transfer student!"

Minato Arisato, while surprised at how excited the school could get over one person (let along someone they didn't even know), was glad to hear that everyone had moved on from talking about the non-existent relationship between himself and one Yukari Takeba. Don't get him wrong, he was definitely attracted to her, but the rumors pretty much killed any shot he had at getting near her. At least, for a while.

Besides, there were at least a hundred other datable teens in the school. Minato really wasn't that picky. And there was always this new kid. Apparently, the guy already had a small following of fans—both fangirls and fanboys.

Minato smirked at that thought, imagining how the boy would react, especially to the fanboys. Then, depending on the reaction (and the truth behind the rumors of him being almost feminine in beauty), Minato could—and would—make his own move.

Yes, depending on the teen, Yukari could wait.

He was lost. He could admit that. This school was much bigger than any of the previous ones he'd been to, and a lot more confusing.

And it didn't help that there was a mob constantly following him.

"Where the hell is 1-D?" he grumbled, annoyed.

Immediately, everyone was shouting out directions that he couldn't understand. He flailed, trying to pick out correct instructions when a hand reached in and pulled him out of the mob.

Blue eyes blinked at the teen before him, who was effectively shooing away the mob that had formed. Many annoyed girls—and a few pissed guys—left under the gray glare of the newcomer.

Then, those eyes flicked to him. "Gomen," the newcomer said, midnight blue hair shading his eyes, "they're excited about a new transfer student. After all, the rumors about me and Takeba-san have died down." He extended a hand. "I'm Arisato Minato, a second year."

He took the hand. "Dan—er, Shun Yamada. First year."

Minato smirked. "You started saying something else. Nani?"

He blushed. "D—Danny Fenton. I—I'm half-Japanese, so I have a Japanese name and an American name."

The smirk changed to a grin. "That's pretty cool. So you're going by Shun Yamada here?"

He nodded. "Hai."

"So you're Shun-kouhai to me."

"Um, yeah, Arisato-senpai." He blushed when he realized how close Minato's face was to his own.

"Then I reserve the right to call you Danny-chan when we hang out."

The younger teen blinked. He heard—and knew—that tone. There was no 'if' in that statement. Minato fully intended to stay around the new(er) teen. The blush deepened. "Ah—umbutArisato-senpai—"

"And you call me Minato-kun. Deal, Danny-chan?" The older boy grinned as though he'd already heard the answer he wished to hear.

"UUm, …mm, hai, deal."

And just like that, the boy's life flipped upside-down.

Thou art I…and I am Thou. Thou shalt have our blessing when thou choosest to create a Persona of the World Arcana….

The teen almost jumped at the sound. "W—Wh—What was that?"

"What?"

"I j—just heard a v—voice in my h—h—head!"

"Oh, that? Heh, you must be a Wild Card, too." Minato grinned at the younger student.

The younger gave Minato a blank stare.

Minato blinked. "Wait, you—you don't know what a Wild Card is, do you?"

"Uhhh… no, why?" The teen almost sounded nervous.

"Okay…. Do you know what Personae are?"

The teen's nervous look grew. "…iie…."

The elder sighed. "Oh, boy…. This is gonna be a long day…."

5|0|_!7 |03|250|\|4|_!7!35

"S—So, could you start over, please?" the younger teen said.

"Sure, now… where to begin…? Well, first off, there's Social Links. They're relationships you form with different people. Each person has his or her own arcane, which is based on their personality. A Persona is a manifestation of that individual's aura. Since you heard the voice, that means you're a Wild Card. That allows you to control multiple Personae. Any questions?"

The teen looked thunderstruck. "U—Uhhh…."

"O…kay…. Well, as your Social Links strengthen, so will your Personae of that arcane. Oh, and when you max out a Social Link, well, the person gives you a gift and you spend a few hours alone together." Minato smirked at the teen, whom, nervous, backed away a couple steps.

Minato chuckled.

"W—What's so f—funny?"

"Nothing." The blue-haired teen shook his head. "You're just one of the most shy, most innocent people I've ever seen…."

"Uhhh… a—arigatou… I think…."

"Don't mention it."

GONG

The teen blinked, startled. "Wh—What the—?"

"Hold that thought," Minato stated. He stood, glancing back at the teen. "Stay here. You may be a Wild Card, but with your ignorance you'll be way more harm than good."

Minato didn't even wait for a response before rushing out the door, slamming it shut on his way out.

The teen scratched his head. Minato's actions confused him. First, he said that it was normal to hear voices, then he demanded to be taken to the younger's house to explain. Now, he'd run off to use his 'Persona', whatever that was.

The teen sighed, heading back towards his bed. He flopped down onto it, suddenly very tired and just wanting to sleep.

He'd only just closed his eyes when he heard a loud crunching sound. Confused, he opened his eyes—

And let out a loud scream when he saw a black mass of hands, weapons, and a mask coming straight at him after having pulled the roof and a wall off the teen's small apartment/house.

The boy backed up, ending up trapped against a wall. He looked to either side of himself, trying to find a weapon he could use. He reached for a lamp on the side table by his bed, but pulled his hand back when the black monster slashed at it. Blue eyes shut tightly in fear as the thing crept closer.

"Ohhh, no you don't!" a new voice yelled. A white-haired young man came running in, throwing his fist into the monster.

"W—What the—?"

The new arrival glanced over his shoulder at the boy, continuing to fight off the thing. "Don't worry, kid, I got this one!" he yelled as he effectively shredded the monster with a barrage of attacks.

The teen was in a total brain lock. "Is it possible to hurt that thing?"

He was answered between attacks. "Yeah… sure…. You just gotta… know… how to… hit it!"

"Uhhh… I'll take your word for it."

"Don't sweat it. …I've fought… these guys… for a while now, so… just let me… deal with this… one solo."

The boy felt his eyelids grow heavy. "Heh… he's all yours…."

"Like I said, don't—"

FWUNK

Another punch dropped the shadow as Akihiko Sanada spun around to see the teen collapsed on his bed. "Huh… guess he couldn't handle seeing one of these guys close-up. Can't say I blame him…." Akihiko sighed, then reached for the teen. "Guess I'd better get him to the Dorm…."

5|0|_!7 |03|250|\|4|_!7!35

"What the hell were you thinking, Akihiko-senpai?" a girl's voice yelled.

The semi-conscious teen didn't move, wishing he could fall back into Morpheus' realm.

"Hey, what was I supposed to do, huh? Let the shadow take him?" He recognized the white-haired man's voice.

"Of course not! You just didn't have to bring him here!"

"Let's try to calm down, here," a second female voice declared. "I'm not too keen on having anyone new in the fight, either, but it doesn't appear that we have a choice…."

"That's what I'm trying to say. I'm as suspicious as the next guy, but he's obviously got some potential. Why alienate someone who could help us later?"

"Yeah, he's green, sure, but who wasn't at one point?" Ah, that voice was Minato's. "I mean, just a month ago, I was, too."

The teen was confused by the conversation. He knew he wasn't in his house any more. His mind went into a state of panic. If he wasn't at home… what if they had finally found him? But… Minato was there, too….

The first girl huffed, probably crossing her arms. "That stupid shadow should've been more quiet…."

The teen tensed slightly, going unnoticed by the arguing group above him. So, at least one of them did want him dead….

Minato blinked; the teen could sense it. "…You're not serious, right?"

"What if I am?" the girl continued. "I doubt he's a Wild Card if he doesn't even know what a Persona is!"

Then the teen's rescuer spoke up. "How do you explain his being awake during the Dark Hour?"

"I dunno. Maybe he was part of some weird experiment trying to let people survive the Dark hour. Maybe he is a user, but I seriously doubt he can use more than one!"

"Okay, so he's a bit late in coming into his power," Minato stated. "So what? At least he's going to live long enough to find out some of his potential!"

The teen bolted upright. "Huh?" he yelped. Had Minato really just said that? But… But he'd been so nice before…. Was it all just a lie? Just a façade to get him comfortable so they could take him? Wad Minato… really one of them?

"Well, well, well! Look who's awake!" Minato grinned, grabbing onto the teen's arm.

"Let me go, you freaks!" The teen squirmed, writhing as more of Minato's group reached for him.

"Whoa there, Yamada-kouhai! Calm down!"

"Calm down?" His voice was ratcheting up in pitch and volume. "Calm down?"

"Yeah, wh—?"

"You've brought me to them, that's why!"

"…You know who we are?" the brown-haired girl in the corner said. She was the first voice the teen had heard.

"Oh, come on! Don't play dumb with me!"

"Yamada-kouh—"

"Don't get all friendly with me, Minato-senpai! You were just playing nice to introduce me to your… your friends!"

"Well… kinda, but—"

"Finally, some admittance!"

"Admittance of what, Shun-kouhai?"

"Don't think I'm not onto you jerks!"

"Shun-kouhai, calm do—"

"I will not calm dow—!"

Everyone stared in shock as the teen dropped to the floor, unconscious.

"Shun-kouhai? Yamada-kun?"

5|0|_!7 |03|250|\|4|_!7!35

'Finally, I have your attention!'

"…huh?" the teen murmured, blinking up at the… floating person above him.

'Oh, please!' the thing huffed, hands on hips. It was white-haired and green-eyed, clad in a black and white outfit with a silvery DP symbol. 'Don't tell me you didn't notice that little twitch in the back of your neck before you conked out in front of that white-haired guy!'

"Well… yeah, but—"

'Bingo! That was me, smarty pants.'

"Then, who—?"

'I'm your Persona. At least, your first. Pretty soon, there'll be a bunch of us in here.'

"You're my—? W—Why do you look kinda like me?"

'Your Personae are facets of your soul. I'm what you hope to be. Someone strong, heroic, who will do anything to protect my loved ones.'

"Not that I have any…." the teen mumbled.

His Persona pursed his lips and huffed. 'And that attitude is part of why you have other Personae. While I'm what you want to be, you'll also end up with the Personae of what you were, your feelings, and what you hope never to become. Among others, of course.'

"…w—what I—? N—No. No, I am not going to have any Personae that are—are—"

'Evil? They're really not. They're just to represent that side of you. I'm sure Minato's Personae aren't all unicorns and butterflies. In fact, I'm sure he has more "evil" Personae than you.'

"S—So… what exactly do I call you?"

The Persona smirked. 'I'm Phantom. And so our journey together begins….'

5|0|_!7 |03|250|\|4|_!7!35

The teen blinked up at the blurry objects above him. A few more blinks, and his vision cleared enough to recognize the blue-haired teen.

"Mina…kun?" he mumbled.

Minato smirked. "Mina-kun am I now?"

The younger blushed, trying to stutter out an apology.

"It's fine, Dai-chan. I don't mind the nickname. I take it you're feeling better?"

"Um, y—yeah. I, um, I met Phantom… er, my Persona."

Minato's eyebrows jumped up. "Oh?"

"H—How do I, um, summon him?"

Minato bit his lip, backing up some.

"Mina—?"

The older teen pulled out a small silver gun, holding it out to the first-year. "Y—You use this. To shoot yourself… in the head…."

The raven-haired boy took the gun and put it against his forehead, finger hooking around the trigger.

"Ah, wait—!"

The gun clicked, but nothing happened. The younger blinked in surprise at the gun. "Why…?"

"You're mentally exhausted. You won't be able to summon until you rest up some. And given all that happened today, I'd say you need to rest for a while."

A yawn. The younger stretched. "Okay. I'll show you later, then…." He lay back down.

Minato chuckled. "I'll hold you to that, Dai-chan."

A/N: So have fun reading this. I added in a few scenes here to make the story flow better, and to fill in some plot holes. I'll try to figure out what's up with the actual, strictly-DP part of this story. And yes, this will go into Persona 4 as well. I'm just changing the year it takes place, so it's right after P3. Read and Review please!
