~True Cross Academy~

Yukio, Rin, Bon, Shima, Konekomaru, Shiemi and Izumo are currently walking to Mephisto's office. They'd gotten an announcement from him to come to his office after cram school for a group mission. No one knew what the mission was, they were all thinking of what it might be. When they reached the door to Mephisto's office, Yukio knocked on the door before entering; once they all entered they shut the door and remained silent, waiting to hear what the big mission was all about. One of the first things Yukio noticed was that, besides Mephisto, they were the only ones in the office. 'If it's a mission that requires all of us then why aren't there any other exorcists?' Yukio thought while looking at his students. The others must have thought the same for they were looking at each other with confusion.

"So, what's this mission you wanted to speak to us about, Sir Pheles?" Yukio spoke up, irritated by silence. Mephisto smirked, which to those who didn't know about his heritage would simply think of it as weird. But to Rin and Yukio, they knew his heritage and therefore knew that he has something big planed for them.

"It's simple, you will be guarding two brothers, and making sure they're out of harm's way for a certain amount of time." Yukio blinked.

"That's it?" He asked, he didn't mean to be rude but for a whole class to guard these brothers but also Rin, the son of Satan to guard them as well? There has to be more to the mission then what Mephisto says.

"Yes, but there's some information you need to know about the two brothers but I'll be leaving that to the one that asked of me to help guard them," Just as he finished Rin abruptly spun around and stared at a man with short dark brown hair in a suit wearing a trench coat. Everyone looked surprised at how this man came into the room without anyone noticing him.

"Everyone, this is Castiel. He's an angel." Everyone stared at him, flabbergasted by what they've just heard. They were in the presence of an angel, but what Rin found strange was why is an angel at True Cross Academy asking for their help?

"I'll leave the explaining to you." Spoke Mephisto, they all looked back at the angel who had made his way to the side of the room before speaking.

"The brothers you'll be guarding are Sam and Dean Winchester. They are what you'd call hunters." He stopped, waiting to see if anyone had any questions before speaking. Shima raised his hand slightly. "Question, what are hunters? Judging by the mission and all, I have a feeling that they don't hunt animals." Castiel looked into his eyes. Shima found it a bit unsettling. His gaze didn't seem to hold any emotion, quite the opposite to what Shima thought what an angel what be like.

"Hunters are people that don't hunt animals, but the supernatural, like how you students exorcist demons except they hunt and kill any supernatural beings that cause harm to humans." Rins tail twitched slightly at that. 'I'm the son of Satan, would they try to kill me even though I haven't harmed or killed anyone?' Rin wondered, a bit nervous now with this thought in mind. Castiel then turned to stare into Rins eyes, noticing his worries. "Don't worry," He said, grabbing everyone's attention "I am well aware of what you are, Rin Okumura. If worse happens I'll make sure they don't harm you." He said calmly. He expression never faltering. Everyone glanced at Rin who let out a small sigh of relief as he relaxed, knowing that he didn't have to worry much.

"Abaddon is back." He said. Both Mephisto, Yukio and Bons eyes widen with shock. Rin, Konekomaru, Shima, Shiemi and Izumo just looked at the others wondering who Abaddon is. Castiel, must've noticed there confusion because he started explaining "Abaddon is a demon, one of the last Knights of Hell or Gahenna as you like to call it."

"Knights of Hell, is she a Demon King?" Izumo asked curiously.

"No, the Knights of Hell aren't as powerful as the Demon Kings; the Knights of Hell were hand-picked by Lucifer himself. Dean and Sam are looking for a way to kill her and need protection and help, that's why God sent me to ask for your help." He finished. Rin slowly raised his hands, signalling that he has a question.

"I don't understand something, it's clear that she isn't a normal demon but what I'm wondering is how do we know if it's her or another demon?" Bon growled at Rin "You an idiot or something!? Haven't you been listening in class?" He growled at Rin who only glared back. "No, he's correct," Castiel said to Bon, who only stared with his mouth hanging open at the angels response. "Demons in the western parts of the world are different to the ones here, but live in different places. For example, demons here live in Gehenna while demons over in America, Australia, England, Sweden etc. live in Hell, the two completely different. Also have different rulers. Gehennas ruler is Satan while Hells ruler is Lucifer, but your methods of attacks will still work on them." He finished, everyone nodded

"You have an hour to pack, when you're done come back to my office, understood?" Everyone nodded but before they all left Rin stopped.

"How long will we be gone?" Everyone stopped, no one had thought about that, they were all thinking about the new information Castiel had given them. Mephisto looked over to Castiel who then looked over to Rin "I don't know, you'll be gone for a long time, maybe a month or so, maybe longer." He said, Rin stood there for a couple of seconds before leaving with Yukio and the others.


It's been a bit over an hour and Rin, Yukio, Bon, Konekomaru and Shiemi are now currently waiting in Mephistos office as they waited for the others. When the others finally arrived, Castiel began explaining to them the story a bit more. "When Abaddon came back to this world, she started hunting down the Winchesters, now she's trying to become the ruler of hell. While with the Winchesters, don't do anything until they ask or say so or if I say so. Also Rin, you can fight with your flames and you don't have to hide your tail. The demons know that Satan has a son but they don't know that the blue flames is the sign of his powers, but don't revealed that you're the son of Satan, if they find out they'll won't be as nice as the demons here," Rin nodded telling Castiel that he understands, although Rin is glad that he doesn't have to cramp his tail under his shirt. "I've been tagging along with them at times, Dean doesn't agree with people guarding them so he may seem rude." Everyone remained silent.

"Are we all ready?" He asked the group they all nodded. Castiel turned to Mephisto "I thank you for helping us, you have Gods thanks." He said bowing.

"Oh it's no problem at all, I'm glad to help in any way I can." He said with his normal smirk. Castiel then turned to the group before they all disappear from Mephistos office.

They were in Mephistos office one minute then when Rin blinked they were inside a large room with bookshelves on each side of the room and three long tables lined in the middle of the room with two young adults sitting down, one reading through some old books while the other on a laptop. They both looked up, the one reading books rolled his eyes. "I thought I told you we didn't need help, Cass." He said with annoyance. Judging by how unhappy he was with their presence, Rin had a feeling that he's Dean. Rin then noticed the guy at the laptop, who he guessed to be Sam, staring at his tail and then at the group, then at his brother.

"Dean, whether you like it or not it's for you and Sams protection." Dean only turned away, rolling his eyes again.

"You've got to be kidding me. First Abaddon comes back now we're being guarded by a bunch of kids."

"Dean..." Warned Sam.

Dean rolled his eyes again, moving from one foot to the other as he moves from side-to-side in a thinking manner. He mutters words under his breath before taking a seat away from the teens and remaining silent; obviously not happy. Now that Rin looked at him more, he noticed how tense he looked and how tired he was. The exorcists didn't know what to do, afraid that if they make a noise they'll anger Dean. Sam, noticing their behavior spoke up.

"So uh…What are you names?" He asked trying to start up a conversation to brake the silnce. Yukio started one by one telling them their names; even Dean lifted his head a little. "My name is Yukio Okumura and he's brother Rin," He said gesturing to Rin. "Those two girls are Izumo and Shiemi and the rest are Suguro, Konekomaru and Shima." He finished. Both Sam and Dean raised their eyebrows at their names, probably at how foreign they sounded.

"Okay, well ah, sit wherever and don't pay any attention to Dean, he's a bit precious at times." He said with a grin. As Rin walked to sit down at a chair near Dean he noticed him turn his head slowly to glare at his brother who only smiled in return. It made Rin laugh a bit inside at how similar they are to the Winchesters.

The others had a look around the place and the books while Yukio went over to Sam and asked about what they are researching. Rin's tail swooshed sided to side and at the movement Dean looked at what was making the noise and noticed Rins tail. Dean's eyebrows raised with surprise. "Hey, kid what's with the tail?" He asked, gesturing toward the movement of Rin's tail. Everyone fell silent and looked at Rin. "Uhh…" Rin didn't know what to say, he was worried that if he said something wrong that it'll make the mission more complicated because they don't trust him. "He's half demon." Castiel spoke up, startling Rin. Sam's face perked up a bit with curiosity while Deans got serious. "You trust a demon, Cass? Not only that but you showed him where we're hiding!?" Rin flinched slightly when Dean raised his voice. He knew it, he knew that the brothers' will be angry at the fact that a demon has to not only help them, but guard them.

"Dean stop," Dean turned his head to look at Sam. "Have you noticed that the others aren't worried about it either, not only that but for Cass to know and to stick up for him can mean that he really Is here to help us." Rin relaxed slightly, knowing that one of them can understand and wasn't afraid of him.

"Where they come from they have a place called Gehenna, it's like Hell but with different types of demons. Dean you don't have to worry, most demons over there live with humans or even help them. Unlike here." He said, standing beside Rin showing Dean that he won't allow him to kill him or kick him out. Defeated, Dean sat back down and turned back to his work while rubbing his face in frustration. Castiel on the other hand, looked back at Rin before sitting down at a chair and stared at the table in front of him.

Night time came and the group of exorcists in training became tired. Rin was falling asleep but when a yawn escaped his lips, he woke up again. 'God this is more boring than school' He thought to himself. Rin looked around the room till his eyes landed on a couch, he got up and walked over to the couch and flopped down. His eyes immediately became heavy and he fell asleep. Dean watched him fall asleep on the couch, his tail swaying side to side as he slept. He turned back to his research but his mind began to wonder.

'Can we trust him? He's a demon after all but Cass did say that over where the kids came from that some demons live peacefully with humans, I find it even funnier the fact that demons have tails. HA!' Dean smiled at that thought. 'Tomorrow' He thought. Tomorrow I'll see if we can rust him'.
