Authour's Note: This is going to be a collaboration fanfiction between me and my sister, jedexa. The chapters will alternate between us. This story is a crossover between the KHR world and the Persona world, taking place shortly after the Inheritance Ceremony arc in KHR, but before Chrome transfers out of Kokuyou. We hope you enjoy the read!

chapter o n e: THE MURDER

"This morning, a man was found dead just outside of the abandoned amusement park Kokuyou Health Land. Autopsies have revealed that the victim was stabbed by a strange three-pronged weapon, presumably a pitchfork. The victim's name is Ambrogio di Estraneo."

"Geez, that's scary…" The brunette muttered quietly, stuffing another spoonful of scrambled eggs in his mouth. He furrowed his eyebrows, concerned brown orbs fixed upon the TV screen. "Reborn, I'm kinda worried…"

"Why?" The small child in a suit responded, dashing across the table and snatching up the teenager's plate of food. "It's not like they're going to come kill you, dame-Tsuna. They're from Kokuyou, which is somewhat far from here in Namimori." Tilting his head backwards, he practically poured the rest of the brunette's eggs into his mouth.

"G-gahh! R-Reborn! That was my breakfast!" The boy named Tsuna wailed in despair. He hung his head in defeat before shaking it off. His efforts were useless—his eggs were good and gone into the baby's stomach. "I mean, that's the thing. It is Kokuyou… what if Chrome and Mukuro are in danger? Or worse… what if they…" The words caught in his throat. Tsuna couldn't finish his sentence as the news report on the TV interrupted him, finishing the thought he hoped never to hear.

"The suspect is a man named Mukuro Rokudo. Witnesses say he is about 180 centimeters tall, is Italian, and has dark blue hair. If anyone has information of his location and whereabouts, please contact the number on your screen."

Tsuna clicked the TV off. Sitting there in disbelief, he continued to stare at the blank black screen of the electronic device, listening to nothing but silence. "I… what… Mukuro… killed somebody?"

"It's not unexpected," the baby hitman replied. "He's killed countless mafia men. There's no doubt that he would kill someone of the Estraneo."

"But… the Estraneo are a mafia too?" Tsuna shook his head, as if denying it.

"Yes. They're the family that made the forbidden possession bullet to start with, remember?" Reborn flicked Tsuna on his forehead, making the brunette flinch and throw his hand up to cover his forehead defensively. Reborn scoffed at how weak the boy was, proceeding to sit down where he stood and play with his curly sideburns.

"O-oh…" The brunette was dumbfounded. "Then… maybe… Mukuro might have… actually done it…" He looked horrified knowing that the possibility could be true.

"Exactly," Reborn sipped his espresso with a shrug.

Tsuna shook his head, standing up and dumping his plates in the sink. "I don't believe Mukuro would have actually done that. I mean, I know that he just got out of prison because of the whole thing with Daemon Spade but…"

Reborn shook his head. "He's a murderer, Tsuna. And you know this."

"Well, I don't know! He wouldn't be so painfully obvious about it, would he? And anyway, so soon after getting out of prison?" The teenager argued profusely.

"Who knows? Anyway, it shouldn't concern you. So what if he killed another guy? This is probably a normal thing for him." The baby muttered, becoming frustrated with Tsuna's arguments. "Murder happens all the time in the mafia. It probably was him, you know."

"Can't I believe that there's still some good in him?" The boss frowned, sighing heavily and turning to leave for school.

Quickening his pace, he sighed inwardly. Maybe I really should just drop it. It's best not to get involved with that guy anyway.

"Boss," a quiet and soft voice spoke up. The brunette looked up, stopping himself just inches away from crashing into the girl in front of him. She stared with one owlish eye, though made no comment on his clumsiness as he scratched the nape of his neck.

"Chrome!" Tsuna exclaimed, both stunned and delighted to see the one-eyed girl. "H-hi! What are you doing here in Namimori?" He asked with a shy smile.

Her eye flashed to the ground. "Boss, we need your help." She said, not looking up at the boy. "Mukuro-sama has been framed."

Tsuna was stunned. "W-what?"

"There was a murder outside of Kokuyou land, and—"

"The victim had the stab wound from a weapon like a pitchfork…" Tsuna muttered quietly. The other girl looked up with big eyes.

"Yes." She didn't question where he learned the information. "It wasn't Mukuro-sama. I know it wasn't."

"W-well, what do you want me to do about it?" Tsuna asked shamefully, finding himself of no use.

"I want you to protect him, Boss." She said deftly. "Please, I beg of you, don't let anyone falsely accuse him. It was not his fault!" The look in her violet eye was desperate.

Tsuna gave her a confident and comforting glance in return. "Don't worry, Chrome. I won't let anyone blame him for something he didn't do. I'll protect Mukuro."

Those were words he never imagined he would say.

What had he just gotten himself into…?
