A/N: Hello, everyone! This is a crossover between Soul Eater, Ouran High School Host Club, and Fullmetal Alchemist. I've been working on this for a long time and putting a lot of effort into it, so I hope you all enjoy it! This is just the prologue, so don't worry; the chapters are going to be much longer than this! Oh, and for the purposes of this story, Crona is a boy. I'll also let you know where in the timeline of the different anime's this story takes place after the prologue. Anyway, here you go!

Journey to Ouran: The Search for the Philosopher's Stone?

Prologue

The night was dark and still. Suddenly, a flash of light appeared along with a slight breeze, disturbing the peaceful air. Out of the cloud of smoke stepped a tall boy dressed in a black, almost floor-length dress. He shook his head to get his pink hair out of his sad eyes and stared up at the massive building in front of him.

The school was huge, with circular windows all around and a big fountain off to the left. To any other person, it might have been a beautiful sight; but to the boy, it was frightening. He bit his lip and gripped his right arm, hoping the school didn't look as menacing in the sunlight as it did in the dark. Suddenly, the boy cried out and lurched forward as a black substance seemed to shoot out of his back. It quickly formed into a creature with a huge white X across its face and bulging, white eyes.

"Crona, what the heck are you standing around for?" the creature bellowed, making the boy wince.

"Ow, Ragnarok, don't yell in my ear," Crona said, frowning. "This place is really big and scary; I don't know how to deal with it . . ."

"Well, you'd better find a way to deal with it soon, because you're gonna have to infiltrate this place starting tomorrow!" Ragnarok put his hands on either side of Crona's head and squeezed it. "You don't want to upset Lady Medusa, do you?"

"Ow! No, I don't! Stop that! Ragnarok!"

After a few more seconds of bullying, Ragnarok disappeared with a laugh. Crona looked dejectedly at the ground for a moment, before pulling out a slip of paper from his pocket that Lady Medusa had given him.

"I'm supposed to find a pure soul here in this school that's supposed to help create this thing Lady Medusa wants to make," Crona said to himself, reading the paper. "What was it called . . .? The philosopher's stone?"

He stared at the paper for a moment, before shaking his head and replacing it back in his pocket.

"Well, Ragnarok, I guess we finally get to go to school," Crona said, looking at the building again.

"Just shut up and get out of here, before someone sees you sneaking around!" Ragnarok said, forming a hand to poke Crona in the side. "If you get caught, Lady Medusa's plan'll be ruined!"

Crona's eyes widened and he quickly started to run away from the massive building, pausing only briefly to read the sign proclaiming the name of the school he was supposed to start attending tomorrow. He rounded a corner and disappeared into the night, already worrying about what his first day at Ouran Academy would be like.
