Rin didn't wait for much longer at the river bed pondering the strange demon, the creepy teacher or what he could do after he'd had a nap. In fact, he trekked all the way to true cross academy alone. At 10 in the morning, as a six-year old. Yeah. It was pretty annoying to constantly get concern and more than a little unnerving after what he'd spent the last decade of his life as: a wanted man. He still flinched when a person walked out of nowhere and checked areas for exits.

The reason he went there was to find Mephisto, the person who had saved him from a life on the edge by sending him back in time to his six-year old self's body and apparently giving up his powers over time to him in the process. To be honest Rin felt the power's thing was a bluff, but the fact that his demon powers had returned with him… It just brought up all kinds of questions he didn't want to face today. Maybe when his head was more in order, but the Half-Demon had been running on autopilot pretty much for the whole time he'd been in the past so far.

Literally, he'd been here for less than a day and so much had happened that Rin felt like collapsing then and there. Mephisto had sent him back in time, he'd discovered when and how he'd been sent. He dealt with a demon, and he met a messed up teacher.

Rin looked around him to see where he was and nearly had his head split in half by a flying gun. He was at the entrance to TCA campus and there was a massive fight between Kuro and some sort of many tailed fox that was just as big. He walked slowly down the lane in such a path that he wasn't going to be stepped on and ignored the dragoons and arias at the scene already like he couldn't see them.

A few of them seemed alarmed by his appearance, but he confidently through them towards the gates, and the demons ignored him in the fight. He walked through the gate without being stopped and immediately started running for Mephisto's office. A few students seemed surprised to see him there, and Rin ignored them and carried on, using his demon fire a little to help him out subconsciously.

Finally, after what seemed an eternity he reached the office and slammed the door open angrily. When he walked in the doorway, still blazing, he was met by a leering Mephisto standing over him and laughing. "Oh, Amaimon! I told you he was going to look adorable now~!" The broccoli brother leaned down from the ceiling and shrugged. "Meh." Rin looked around for a second. Then up. Then he became a human torch, swishing his tail around to pull Mephisto's legs out from under him as he walked further into the demon's office, before turning around and glaring at them.

"What's going on! You said I'd be sent back to my old body or something like that- didn't you?" Mephisto grinned. "That I did, Rin. It's only been a few hours though- is something wrong~?" Rin practically snarled at that, but then he focused. Getting mad wouldn't help anything and he would end up with more questions and NO answers. At least this way he could get some answers. The half demon took a breath and looked down, before speaking again.

"I came back in time somehow- you still have to explain what you meant by you losing your powers sometime- and now I look like I'm a demon even though I haven't seen the damn sword, let alone touched it!" Mephisto's grin faltered a bit as the minor rant progressed. The jester looked around slightly nervously, and Amaimon walked out the door upside down. Mephisto sighed resignedly, before replying.

"Well, I didn't lose my powers exactly- woo! But you still have to have some degree of time control ability otherwise your consciousness would have burnt up on the way through the Fissure. I'm curious as to why you're here though…?" Rin almost growled, barely keeping himself in check he grit his teeth and spoke very slowly and precisely. "The first teacher is a complete psycho who the damn Coal Tar seem to love, and I ditched class. Now answer the damn question!"

Laughing, Mephisto walked around him to sit in his large plush office chair. "Do you know how time travel works?" A deadpan stare was the only response from Rin. "Ah. Of course you don't. Time travel is possible because of the nature of a demon's soul. A demon's soul allows them immortality: it contains all of their energy and memories and is able to overcome weaker souls. A human soul is typically much weaker, and that is why we can possess them. You following?"

Rin shifted his position a little, so that he could quietly drag a chair forward and sit down without too much hassle as he nodded. This was getting a little too technical for him… Mephisto leaned forward, resting his head on folded hands before continuing while keeping Rin's eyes.

"Human souls contain little to no energy and Exorcists can train that up, enhancing themselves in the same way we do by instinct through sheer work. I'm getting on a bit of a tangent here…. Time travel works by a demon basically throwing their soul into an abbys known as the Fissure of Time. Get it? When the Soul is falling the demon falling gets glimpses of times in their lifetime, and at the slightest tug of want they will be pulled into their old body, except they are sending their soul back. Of course their body isn't going to be exactly as they left it. Do you get it now?"

Rin frowned a little, and opened his mouth to speak, then closed it again. He looked questioningly at Mephisto, who continued, obviously bored, with his speech. "I said earlier your consciousness would have burnt up, and I wasn't lying. Human souls are generally too weak to make the trip and your soul wasn't exactly the most different, being as you'd suppressed your demon side's instincts and hidden your powers so much for so long. I mostly replaced your human side with my Demon powers, which was more than a bit tricky."

He leaned forward now, still not breaking eye contact with Rin. "You are now full of enough power to class as a king of demons even though your original power levels are still sealed within the demon slaying blade, and I am weaker than usual after the. If you wanted to you could challenge me for my title as King of Time. However, I doubt that's going to happen so I'll tell you one thing. The current King of Dimensions is so weak that a middle high class demon would have kicked him off by now if it wasn't for his intense trap laying skills. The only catch to your Time Travel was you bringing your powers back with you, and that means I want you to take the crown of Dimensions at some point."

*leans back* WOO! This felt like it took for-EVER to write, although I'm rather pleased with it. I'm not too sure about how good I am at continuing chapters, and now I'll leave you with this cliffy. Please review this time~! (mentally glares at all the people who forgot to last time) it really helps. Seriously. I might start making Omakes sometime for this to give motivation to myself.

Also, do you guys want to see a little cute one shot for no reason from me?
