Hello my Fallen Ones! I have finally returned! I have had this chapter done for a while, but sadly haven't had time to update :'(. On the bright side though, I worked on Chapter 14 during the wait, and it's proofread so you get a double update! Woo! This is the last power chapter (Thank god right?), so the plot can finally start. As I said a few chapters ago, I have the story mostly planned out, but getting into the plot might be slow so be patient with me please -. Thank you to everyone who reviewed. They made me happy! Sorry for the troll last chapter though, hehe. Anyway, here's Chapter 13. Enjoy!

Disclaimer: I do not own Blue Exorcist!

Not So Much a Warning, But Heads Up: Other Pairings Mentioned

"Talking" 'Thinking' Satan Talking "Animal Transformation/Demon Rin Talking"


~Rin's POV~Cram School~

Today has been a weird day. Though that was becoming normal since they received their powers, so it wasn't really that weird anymore, but certainly odd. Rin had a few tests today, and decided to… practice his mind reading on the smartest kid in each class. They all happened to sit next to him, his teachers probably hoping the smart would rub off on him, but every time he released his pheromones to read, he kept seeing other people when he dug further. Sometimes he knew the people, others he'd never seen before.

Rin was confused to say the least, but just finished his tests and quietly snickered at his teachers' surprise. He was now in cram school, and was trying to figure out what these images were with the help of his friends, and without their knowledge. Looking in to their minds, in Konekomaru's he saw Shiemi, smiling as always. Shima's had a tsundere Izumo, small blush and all, while Bon had someone he'd never seen before, but she looked foreign. Sort of like a punk rock… Lolita? Shota? He couldn't tell, but American maybe?

Rin shrugged to himself, looking back at Shima, "So how are things going with Izumo?" he asked. After he had learned to reign in his pheromones, Izumo had flipped out, coming out of her haze to Shima's arm around her waist, and hadn't talked to Shima since. That had been about a week ago, and Rin felt kind of bad about it.

Shima winced, looking sad as he tried to keep him care free grin, "She still refuses to talk about it," the pinkette sighed.

Rin frowned, feeling worse, but was quickly distracted by wondering what the flash of pink-white, orange, and red-orange around the Izumo in Shima's head meant. 'Love, attraction, desire in the purest of forms they can be,' Rin thought before blinking, 'Where the hell did that come from?' as he responded to Shima, "Women are stubborn aren't they?" he joked.

"More like crazy and stubborn," Shima grumbled, pouting and making the other three laugh as Yukio told everyone to get to their seats to start class.

~After class~Training Room~

'Dem. Hey Dem. Dem~!' Rin mentally called on his way to the training room, trying to get ahold of his demon side, 'Dem!'

"Who the hell is Dem?!" he finally answered, sounding annoyed.

'You.'

"What?"

Rin sighed, 'Well you said don't call you Demon Me, and you haven't given me a name so Dem, short for Demon,' he shrugged like it was obvious.

Demon Rin sighed, "We're an idiot. I guess you do need to be able to get ahold of me… Ren. I'll go by Ren. Simply so you don't make any more stupid names! Now what did you want?"

Rin huffed at the attitude, 'I was going to ask about the people when I read others' minds and the burst of colors around the Izumo in Shima's.'

Rin could practically hear the blink in the pause before a smirk was audible in Ren's voice, "So you stumbled upon those powers? Snoopy aren't you?"

'Well I couldn't find the answers, and their minds are so easy to sneak into,' Rin grumbles, 'And what powers?'

"As Lust, we can see people's, to use human terms, soul mates. Whether they know they like the other or even know the person or not. After that is mastered, or in your case discovered, colors can be seen on the mate and threads of color can be seen between people. What the colors mean is pre-programmed into us," Ren explains simply, laughing, "You're brother's going to learn his shit when he learns you learned not one, but TWO powers without being taught!"

Rin nods, snickering himself as he's able to perfectly picture Yuki twitching at the news, opening the training room door to find Yukio, Mephisto, Amaimon, and Kimiko already there; Kimiko torturing Amaimon by playing keep away with his sucker.

Mephisto chuckled at the sight before noticing Rin, smirking, "Hello kitten."

"Hey clown," he nodded, amused by Amaimon's whining.

Mephisto raised a brow, but remained amused as Amaimon monotonously whined, "Kimi! Give me back my sucker!" while slashing at her with his claw like nails.

Kimiko had taken notice to Mephisto's greeting, and smirked at Rin before throwing the sucker, "Fetch!" Amaimon scampered after it as Kimiko laughed before turning her attention to Rin, "You ready?" she asked.

Rin nodded, "Yeah, what're we learning?"

"Today we're learning Seeing Desireds and Bonds between people."

A smirk spread across Rin's face, "I already did."

Kimiko and Yukio blinked at Rin, "What?"

"I already learned it. It was an accident, but I still learned it," Rin grinned, looking rather proud of himself.

"Oh? ...Well alright then," Kimiko nods, "Alright, this actually benefits both of you then. We can move onto second-level animal transformations, or Beast Transformations. This will be the last demon power lesson too."

"We have another transformation?" Rin asked, tilting his head.

"Is it the weird half-lizard one Amaimon had when he attacked us at the Vatican when Rin demoned out?" Yukio asked, Rin looking more confused, "You were crystalized. You wouldn't remember," Yukio explained.

Rin nodded before grinning, "Sweet! Let's learn that!" looking to the chuckling Kimiko hopefully.

~All POV~

"Alright we can do that," Kimiko nods, "You'll have to turn to your animal forms."

"Odin, dra, dree!"

"Un, due, tre!"

The twins both call their transformations; Rin turning into his small panther form, and Yukio to his wolf hybrid form.

Kimiko, despite having already seen Yukio's animal form, still had to snicker a little, earning a glare from the hybrid.

"Come on! Come on! Let's go!" Rin cheered, knowing he sounds like an excited kitten.

Kimiko chuckled, "Alright, now this is actually really simple, it just takes a lot of energy when you're in this form. It can knock you out for a few days after too, depending on the amount of time spent in it, so thank god it's Friday," she explains, getting nods of understanding from both twins. "All you need to do is be in you animal form, and, in your demon language, say beast."

"…That's all?" Yukio asked, not used to the simplicity.

"Yep," Kimiko nodded. "That easy, so come on," gesturing for them to go ahead, "One of the humans is dragging me to something called a club, and I'm sure she'll damage my ears if I'm late," Kimiko sneers at the thought.

Rin doesn't need to be told again, closing his red tinted eyes and focusing; Yukio sighing and doing the same with his violet tinted eyes.

"Zver'" Ren tells Rin, simply so he'll be quicker than Yukio.

Rin nods, "Zver' (зверь)" Rin repeats moments before Yukio gets his.

"Beastio," Yukio says as both start changing.

Rin turns back into a human form of his normal height with his hair growing longer; growing down to his shoulder blades and fluffing out into almost a mane of his bluish black hair. His already sharpened teeth grow as well, and turn deadly as his nails turn to claws befitting of shredding flesh like butter. His pupils turn to slits as his eyes glow the color of fresh blood, and his single flicking tail turns into five whip like ones. To finish of the new demonically beastly appearance, two black horns spiral out of his mane and ignite in his now red flames.

Kimiko whistles in appreciation as Mephisto snaps his fingers, a full length mirror appearing in a puff of pink smoke.

Rin blinks a few times before looking in the mirror, his eyes widening at the sight, "Whoa…"I look bad ass." Staring at himself in awe, turning quite a few times to look himself over, "This is sweet!" he grins before looking to see Yukio's transformation, "Yukio, look! I look awe- Whoa!" finally seeing his brother.

Yukio was just opening his iridescent purple eyes that now resembled those of a snake as he glanced at Rin, "Cool," he nodded, now huge fangs getting in his way a little. Yukio wasn't fazed by his brother's look of shock as he walked over to the mirror to look at himself and smirking at what he saw, "Not bad."

Yukio looked himself over, admiring the great dragon wings adorning his back in a deep purple with purplish-pink webbing. His smirk revealed that his wolf fangs had turned slender and more deadly, slightly protruding from his upper lip as he noticed his tongue had forked. He had patches of deep purple scales on his cheeks and hands as well as scattered all over his body that seemed to shine under the fluorescent lights of the training room. His claws had also grown and turned just as lethal as his teeth. He had a feeling of what he'd find if he turned around, and wasn't disappointed; turning to find a purplish-pink tail protruding from under his coat (A/N: For tail color, think Hiyori Iki from Noragami.). Similar to his brother, he had horns spiraling out of his hair. Unlike Rin however, his were smaller and weren't on fire, the fire instead coming from his mouth, surprising him.

Yukio smirked, "Finally, a form befitting my strength," noticing his voice was also huskier as he looked back at his brother, "Sorry Nii-san. I think I win this one," smirking again when Rin nodded blankly before he looked at Kimiko.

"Wait, why did he turn from a wolf to a dragon, and I'm still a cat?" Rin had to ask her.

Kimiko was looking at Yukio, obviously slightly impressed, "Clans each have an animal, and the demons of high enough rank to have two transformations usually have at least one of their clan animal. You happened to get both of your transformations as your clan's animal, which is felines, while Yukio's second level seems to be his clan's, which is dragons," Kimiko explained.

"Pride is dragons?" Rin asked, tilting his head.

"Can you think of a more proud animal?

Rin thought for a moment before shaking his head, "No," before asking, "So what are the other clan animals?" he asked curiously.

Kimiko smirked, "Look who's the over achiever today."

Rin turned a little pink, looking away, "I just don't want to get mauled if I try to pet a puppy," he mumbles petulantly.

Kimiko chuckles, "Don't worry, my clan is well behaved…unless it's Black Friday."

"Black Friday?"

"Not even dad himself can stop Mephisto and I," she says awkwardly, "Heh, it gets ugly…"

Rin raised a brow, trying to remember what Mephisto was, "…Mephisto is…?"

"Greed," Kimiko answers. "The clan of snakes. I'm Envy, clan of canines."

'That explains Black Friday.' Rin nods, "That makes sense," he says, looking to Mephisto who raises an eyebrow, but just keeps his smirk. Rin looks over to Amaimon, "And him?"

"Gluttony, pigs."

'Guinea pig,' Rin nods, "Koori in Wrath?"

"Birds of prey. Last is Sloth which turns into just that," Kimiko answers.

Rin nods in understanding, "That's kind of cool," he admits, looking behind him at Yukio, "Right Yuk-Yukio?! What the hell?!"

Rin had turned around to find Yukio missing, following a tail up to see that Yukio's wings were actually functional, and the younger Okumara was smirking down at his older brother.

"I definitely win," Yukio snickered.

Rin rolled his eyes, "Show off," he grumbles, glancing back at Kimiko, "So it's this easy?" he asks.

Kimiko nods, "Yep, one of the easiest," seeing Rin nod as he glows to turn back. "I wouldn't turn back until you're in your room though. As I said, it takes a lot of energy and most pass out after their first-" she gets cut off by Rin hitting the floor unconscious and sighs, "Yukio, take him back with you. You'll both probably be out 'til Monday," looking up at the ironic Dragoon.

Yukio tries to hide his worry as he swoops down, landing next to his brother, "Yeah, I'll take him," he nods, picking Rin up, being careful not to claw him, "Is it dark out yet?" he asks, not wanting to be spotted in his current state.

Mephisto checked his pocket watch, "By the time you make it outside," he nods.

Yukio nods in return, exiting the training room with an unconscious Rin, "Good night then." Yukio carries his brother outside before flying back to their room, getting both ready for bed, and passing out as soon as he turned normal upon climbing into bed.


Yay! New chapter! And right after this you can go read 14! Yay~! I'm sorry if this one wasn't too great. I'm having a slight writer's block so it's XP. Hope you enjoyed it at least a little though! I got the idea for the description of Rin's beast transformation from my new proofreader (like to have two) Meagan, and Yukio's I came up with from watching Monster Musume with the Dragon newt episode (this chapter has not been waiting THAT long I promise ~). Hope you enjoy the next chapter!
