Rin walked away from the boy's dormitory. Bon, Shima, Konekomaru and Him were supposed to meet up at the library for an errand that Yukio had assigned them. They still hated him, he knew it, but with Kuro at his side, nothing could possibly go wrong.

He met up with them and got a glare from them and a scared glance from Koneko. He looked away guiltily and walked on, pulling the list out and going in one of the aisles looking for a book on demon kin of Astaroth. He frowned when all he found were assorted books of all of them together. He rolled his eyes and got 'Demon kings and their kin, the complete collection' instead, hoping it might calm his little brother's wrath a little instead of going home empty handed.

He blinked stupidly when he heard a commotion in the lobby, where Bon and co. had already gotten their books and Kuro was begging for treats. A cloaked figure behind them did something to Kuro and left in a blue vortex, out of anger, and without even bothering to put the book back, he raced after the man, taking a pissed Kuro with him, who now sported pink fur, and surprisingly enough, Bon, Shima, and Konekomaru followed.

"Where the hell..." Rin stood outside a village. On the doors was ancient writing, old Japanese to be exact. He remembered when he had gotten grounded when he was younger for fighting and he would often read books to pass the time. Unfortunately or fortunately for Rin, the books the old man had given him were ancient history, and he had studied Old Japanese so he could write secret codes to his brother when they were up to mischief.

Bon stood behind him, Shima following. Rin turned back, "Where Konekomaru?" Bon tched, "He stayed behind to tell sensei what happened, the portal closed so they're probably going to have to get Mr. Pheles on the case. Rin snorted, "Like that old clown is going to help me is zilch. Bon squinted at the writing on the big wooden gates, "What kind of writing is that?"

Rin shrugged, "It's old Japanese, I'm very fluent in it since I studied it when I was younger." Bon looked shocked, "YOU STUDIED?" A tick mark appeared on Rin's forehead but he explained nonetheless, "Yeah, since we didn't have a t.v. at the monastery, my old man would often give me books when I was grounded to read to pass the time. I eventually came across the language in one of my ancient history books and started using it so that I wouldn't get caught if I had to write a message to Yukio during our pranks on the other priests."

Shima looked interested, "What did you get grounded for?" He grinned like a pervert, "Did you peek on too many panties?" Rin rolled his eyes as he looked around, "No, that was my old man's job, I got grounded 'cause I kept bashing other kids' faces in, once I broke another kid's nose so bad that they had to do surgery because it was wedged deep into his skull tissue.

Bon glared at him and he felt aggression, "Figures for a demon child like you." Rin stopped for a second.

"Get away from me demon."

"Demon, Demon, follow the sounds of clapping."

"I'M NOT A DEMON!"

"Run or he'll kill us all."

"Now look what you did, he has to go to the hospital now."

"Daddy, am I a demon?"

"No, you're my human son."

"Okay."

Rin shook it off with Kuro on his shoulder, he still had the book in his hands when he went into the village. Bon and Shima followed at a long distance, Shima more close that Bon.

He looked at all the signs and smells and was confused, where did he go? And why were people just ignoring them like they were normal, they had their uniform on for Fujimoto's Sake!" He sighed and when to a shop that said "INN" He hummed to himself and went to the front counter, where an old woman stood smiling, while a boy with blond hair and blue eyes was arguing with a boy with brown hair in a pony tail and looked like he wanted to be anywhere but here.

"Room for one please." The old lady smiled kindly, "Oh, why I don't think I've ever seen your kind here, are you from the modern city?" Rin shook his head, he didn't want to lie, last time he tried to his dug himself a shit hole deeper than hell. "No, I'm from true cross academy ma'am, no where near the modern city. I work for the Vatican you could say."

The woman gasped a little, "The Vatican, as in the feudal lord's organization for demons?" Rin sweat dropped and nodded. "Yeah but I work for Mephisto, who intern reports to the Vatican." The old woman looked confused, "Mephisto, Why I've never heard of him." Rin looked puzzled for a moment, Mephisto said he lived to be over at least a couple centuries, did he not go this far back?

"Hmm, maybe you know him by another name? Samuel John Faust?" The woman seemed to recognize it as her eyes widened a little. "oh, well why didn't you say so? Samuel has visited a few times, since you know him, would you like one of the first class rooms?" Rin nodded, if it's not too much trouble." She smiled and gave him a simple silver key, all the way to the third floor, all the way to the right.

His little conversation with the woman had caught the attention of the two bickering boys, who looked at him with interest. Kuro was still on his shoulder, trying to lick the pink off.

"Hey mister, are you really working for the Vatican, or are you just lying?" Rin stopped and looked at the boy with the pony tail, "Undeniably I am, I'm actually a relative of his," He closed one eye and showed his fangs by opening the corner of his mouth, and put his finger to his lips, "But let's keep that a secret shall we?" He then kept walking. "Oh and Ms, if you see a boy that looks like a rooster and a boy that looks like a walking lollipop, I know em' and I'll pay for em too.

"As soon as I find out what the hell their currency is, dammit Rin why don't you think these things through?"

Rin set the book on his bed and took off his jacket and shirt, letting his tail loose. Kuro leaped onto the bed. Rin looked confused for a moment, "Kuro, you're being awfully quiet." Kuro still refused to look at him, and then finally said. "I don't wanna talk about it." It the girliest voice Rin had ever heard. He burst out laughing. "What did that guy do to you?" Kuro stamped his paw on the bed.

"I smelled him, it was Mephisto, he sprayed a bunch of icky smelling powder on me! But he told me to give you this, like he knew you would follow him." Kuro held out set down a pink flip phone that Rin just noticed was wedged in his collar. The phone had dice and an anime girl on it and a bunch of stuff only a frilly girl would put on her key chain. He flipped it open and there were millions of contacts, one that he came across said Daddy with hearts on either side of the word and he shuddered.

No doubt that this was Mephisto's damned phone." He sighed and looked at his recents, the most recent was one that said, 'please call me' "Ah what the hell, why not?" He called it and not one ring later Mephisto answered. "Hello little brother, it seems Kuro gave you my phone. I have a challenge for you. My plans for you have backfired yet again since Angel threw a wrench in them. Right now, both I and you have disappeared from the modern world, no doubt that your little brother is panicking at the moment.

I need you to stay here until I say, unfortunately your 'friends intervened, I had to get rid of them as you have or haven't noticed, don't worry, they of course returned to the modern world safely, but since the Vatican is out for your head, you will be staying here as I have already said, under the cover of my little brother. You travel quite frequently in search of those in need and you are the arch night of the Vatican and secretly the demon king of unholy flames. My package that I am sending you is coming in 5, 4, 3, 2," He hung up, before Rin could even cuss him out. On the bed was a dark blue uniform. It had a black long-sleeved shirt and a dark blue long coat that went to his knees. He had black combat boots and black combat pants with chains that he realized were soaked in holy water. It also came with black leather gloves.

And the most memorable was the necklace, the very same that his father had killed himself with. "I-I thought he was buried with it." Last was a hair tie, and a little note next to it.

"I noticed your hair is getting longer, to the back of your neck to be precise, side effects of the portal. Wouldn't want it to get in the way now would we? ;)

your favorite brother, Mephisto."

"I wonder if he still dresses like a clown." He dressed into it reluctantly. He clicked his sword at his side with the special belt that came with the pants, putting his cover on the the bed. "Well Kuro, I'm out, gotta do work like the old clown said, so how long do you think before this all blows over? Two, maybe three weeks?" He didn't get an answer, not expecting one as Kuro was still too embarrassed. He tied his hair back and walked out, throwing it next to Kuro who hissed at it's sudden appearance. He rolled his eyes and left.

He walked back down to the lobby where more kids were. "what's going on here?" The boy in blond looked at him with curious eyes, "Hey, I wanna ask you a question, why do you feel like Kyuubai?" "UUUHHHH."

AN: Well, Rin still manged to give himself a hole. And what's up with Mephy being nice for once?
