Hello my Fallen Ones! I apologize so much that the first version of this chapter sucked! It took me so long to write the chapter so when something finally brewed in my head I was sort of desperate! Despite this this is still the longest chapter yet of this fan fiction! I am so sorry that the first version sucked so badly, but I hope you enjoy this version a lot better because my proofreader and I certainly do! I've already started Chapter 10 so that will hopefully be up soon. I also wrote a Durarara! Shizaya fan fiction if any of you want to check that out! Hope you like this better!

Disclaimer: You're all probably really grateful I don't because it would really suck! TT_TT

"Talking" 'Thinking' Satan Talking


~Yukio's POV~

Training Room

Yukio, of course, was the first to arrive in the training room after class was dismissed. 'Pheles-sensei expects us to be here, and he can't even show up on time? Pathetic,' he sighs in frustration as the aforementioned clown prances into the room in his dog form.

"Punctual as ever Yukio-sensei," the little white dog says in the regal manner common of that form.

"And as usual, you're not Pheles-sensei."

In a cloud of sparkly, pink smoke, Mephisto appears in all his clown glory, "Kimiko's right you are bitchier than usual," he smirks.

The Dragoon glares, rolling his eyes, "Am I working on the candles again or do I get to do something productive today?" he asks, already bored.

"Yes, you'll be working on your powers of Pride," the clown says, flashing his smile that never means anything good.

"So I'm working with Kimiko then?"

"Not exactly," the Demon of Greed chuckles as a huge hawk flies into the room, landing on the back of his floating pink chair, "Say hello to Koori Kaze, I'm sure you've met him in your class."

Yukio could have sworn the hawk was smirking, 'I'm doomed…'

Pride and Wrath, yes this should go splendidly~! Satan chuckles in the Dragoon's mind, and for once, Yukio didn't argue.

"So Rin gets sexy Kimiko, while I'm stuck with a meat head with anger issues? Great, that's just great!" Yukio grumbles.

"Yeah, we're going to have to work on that," a voice says from behind Yukio as he's kicked to the ground, the hawk no longer on Mephisto's chair.

"What the Hell?!" Yukio growled, eyes flashing purple, "Don't touch me, scum!" not detecting the change in his normal behavior, "Filthy demon!" he yelled as a foot slammed down on Yukio's chest.

"Awfully high and mighty aren't you twerp? Look in the mirror! You're a demon now too puppy! Learn some respect for your elders!" Koori snarls, irises completely black as he accents each exclamation with another stomp to Yukio's chest, "Filthy mutt!"

"Enough Koori," Mephisto said in a voice of rare seriousness, "Save that for training, you'll kill him at this rate."

"Tch," letting Yukio up.

Yukio growls at Koori as he stands up, eyes flashing purple as he says, "Can we just get on with the lesson?"

"Whatever," he snarls, "I should teach you how to control that new attitude first, but we'll work on pheromones as well I guess."

This brought Yukio back to reality as he fixed the glasses that he now mainly wears for show, "I can use pheromones too?"

Koori nodded, "All demons have pheromones for something."

"What's Pride?"

"You can force your will onto others," Koori smirks, "Almost like mind control but not as powerful as Lust."

Yukio tries to act disgusted, "Seriously?" 'That is awesome, maybe my class will actually learn something for once,' Yukio thinks, other things in mind as well.

"I know it's awesome," before looking puzzled when he actually looks at Yukio, "Why do you look like it's the worst thing ever?" falling for Yukio's façade.

Yukio internally smirks at Koori falling for it, "It's not important, let's just get onto use, who can I use it on?"

Koori rolled his eyes, "Humans, of course, and any demons with less will power than you."

"Well I'd prefer to learn demon first then considering it seems once you learn demon, humans are child's play."

"We've got to wait for your numbskull brother to get here first," Koori says just as Rin runs into the room.

"Sorry, Yukio made me clean the boards," shooting a glare at Yukio, "and fix my desk," shooting one at Koori who smirks.

"As long as you're here," Mephisto says, waving it off, sensing something interesting was about to happen, "We were just talking about you, come stand by your brother."

Rin does as he's told as Yukio sighs, "Why do we need Rin for this? He's the most stubborn-"

"Hey I'm right here!" Rin yells indignantly.

Yukio covers his newly sensitive ears to the assault, 'Does low brain power count as low will power?' "Never mind, I understand now," Yukio says to Koori, Rin now looking confused.

Koori chuckled, nodding, "ready then?"

Yukio nodded, "Yeah, what do I do?"

~Both POV but mostly still Yukio's POV~

"Um, what are you gonna do?" Rin asked confused.

"Yukio's going to learn how to use his pheromones," Koori explained, "So just sit there and behave," he smirked.

Yukio kept an air of calm while on the inside he was grinning evilly, 'Be prepared, Nii-san,' he thought.

Rin nodded considering he had technically practiced on Yukio the day before, "Alright."

Koori nodded in return, turning back to Yukio, "You're apparently the smart twin so I assume you know how to start this from listening to Kimiko train Rin yesterday?"

Yukio nods, drawing his powers into a small purple ball before releasing it into an aura that he trained on Rin. Rin blinks a few times, not realizing he's fighting it, but still feeling it. "What's next?" Yukio asks.

"Give him a command."

Yukio nods, trying to think of something before grinning smugly, 'I think payback for almost breaking my ribs is in order,' he thinks, sending a message to Satan, 'Hey Satan, tell Kimiko to get down her, and that I've seen the books she reads in my class, I know she'll want to see this,' he smirks.

What are you up to my sneaky child? Satan asks, smirk clear in his voice.

'You'll have to wait and see.'

Hue Hue Hue, don't mind if I do, and she should be here in…, Kimiko walks into the room, trying to act like she didn't just run there, now. (A/N: For his laugh think of Kusu Kusu from Shugo Chara.)

Both Rin and Koori now looked confused as Kimiko sent Yukio a 'this better be good' look. Yukio looked smug as he looked back at his brother who was looking between the three demons around him, thinking, 'What Is going on? Why do I have a bad feeling about this?'

"Rin," Yukio called, causing Rin to look at his younger twin and find himself looking Yukio dead in the eyes.

"Yeah?" feeling his remaining will slip the longer he stared into Yukio's violet eyes.

Yukio smirked, somehow able to tell he has complete control, "Go make out with Koori," he orders his older brother.

Kimiko's eyes bulged as did Koori's, though his shock quickly turned into a growl as he backed up, "No fucking way!"

Neither twin was listening though as Rin nodded, and was suddenly in front of Koori.

"Shit, when did you learn how to move so fast?" Koori growled, moving back, Rin stepping forward and the two continuing this until Koori was backed against the wall, "Shit! Don't you dare even try Shrimp!" he growled at Rin who looked unfazed.

Yukio smirked, "Come on Rin, get on with it."

Rin nodded numbly, grabbing Koori's wrist when he tries to knock the shorter demon away, holding them in a death grip, and kicking out his legs in a quick move to pin him.

"What the hell did you teach him Kimiko?!" Koori growled, ready to ram his knees between Rin's legs when Rin uses his own hips to pin Koori's down as his eyes turn red, "Shit! Okay Yukio, you pass! Now get your horny ass twin off of me!" he roars, knowing neither Mephisto nor Kimiko will help him when they each pull out charmed camera phones.

"Hmmm," Yukio hums, pretending to consider it before grinning, "No I don't think so. You shouldn't have picked a fight with me now should you?"

Koori's growls are cut off when Rin crashes their lips together, closing his eyes as Koori's go huge. Mephisto chuckles as Kimiko squeals, Yukio smirking in triumph as Satan cackles in his head, You my boy are evil!

'Thank you,' he responds simply, his eyes turning dark though as he loses his look of triumph. Something at the back of the Dragoon's mind, in the part he's come to associate with his demonic instincts, snarls as Rin holds Koori's wrist above his head with one hand, stroking through his hair with the other. 'Mine,' the voice snarls, 'the boy is mine. Destroy the threat, kill the competition,' Yukio's eye turning a much darker shade of purple and looking like fire themselves.

Koori was red and struggling the whole time before Rin bites his lip making him yelp. Rin takes this opportunity to slip his tongue in the others mouth, making Koori's eyes go wider than before.

Before Yukio, or anyone else, even realize what he's doing, Yukio is next to the two, ripping Rin off of Koori, and glaring down at the demon of Wrath with murder in his eyes. Rin's eyes turn red, and already normally sharp teeth are even longer as he thrashes around, trying to complete the command he was given. "Fermata," Yukio growls in a dark voice, making Rin freeze as Yukio stares into his eyes, "Comando di fine." Rin's eyes closed as the command was released and he fell still, passed out. Yukio handed Rin to an amused Mephisto in his floating pink chair before looking back at Koori.

Koori was catching his breath from the short period of oxygen deprivation, but glared daggers at Yukio, "You are so dead you Little- oof!"

Koori didn't get to finish as Yukio kicked him in the gut, growling, "Mine."

"You're the one who sicked him on me!" he growled, trying to stand up only to be kicked in the head.

"Oh my, it seems he's demoning," Mephisto smirks.

Kimiko was starting to get worried when Koori's eyes turned black, and he laughed at Yukio, punching him in the jaw and knocking off his glasses.

Yukio blinks, grabbing the arm before it can retreat as he spits out blood before flipping him to the ground on his stomach, one foot on his back while he holds the arm in a death grip, "Kill."

"Which one of us is Wrath again?!" Koori growled.

"Mine," trying to tear his arm off now.

Yukio's eyes flashed and a half crazed grin took over his face as he snapped Koori's wrist before letting him go, kicking him in the head when he tried to get up, "Nonmento se lo faccio," completely demoned out to the point of speaking his language as he walks over to his brother who is still lying unconscious across a very confused Mephisto's lap.

"Yukio? What are you planning?" the clown asked, ready to move Rin if it was something unfavorable.

"Miniere," grabbing Rin's wrist as the purple in his eyes turns iridescent.

Mephisto's eyes widened in understanding, "Shouldn't you wait 'til he wakes up so he can consent? This is permanent after all," in a rare moment of reason.

Yukio shook his head, 'He's mine, I'll make sure no one else can have him,' he thought possessively.

I think I remember warning Rin of this yesterday… Satan snickered.

Yukio ignored him, running off of instinct as he used his canines to bite his wrist open before doing the same to his brother's. Rin let out a small whimper that turned into a slight moan that made Yukio and his inner demon smirk. He didn't fail to notice his older twin's fangs lengthening again either.

His inner demon is reacting too. He smells your blood. He wants you just as much, Satan snickers, go for it.

Yukio doesn't have to be told twice as he puts his bleeding wrist next to Rin's nose who sniffs, and makes a grab for his younger brother's wrist in his sleep. Kimiko cut in, pulling Yukio away before he could though as Mephisto tried to get a now thrashing Rin to hold still. "What are you doing?" Yukio growled, having difficulty not saying it in his demon language.

"We don't know what will happen if he gets blood," she says, unfazed by the Dragoon's death glare, "we've never had a half-demon as Lust clan leader, he might lose it," watching Mephisto having difficulty with the Knight-in-training.

"Why would he go nuts from some blood?' he asks, but continues before she can answer, "I'm stronger than him anyway so it's not like it matters though. I can handle him."

Kimiko rolls her eyes, "Damn Pride, always such asses when people try to help them," knocking him on the head, getting her thrown into Mephisto's chair, knocking the clown and Rin out of the chair in the process.

"Quiet peasa-!" Yukio tries yelling at Kimiko, but is cut off as Mephisto loses his hold on Rin who tackles Yukio to the ground and pins him. Yukio's head smacks the ground hard, managing to knock him back to reality with a groan, "Ow~," Yukio blinked up at Rin who's eyes were open, but red and glazed over and he had an impish grin, "Nii-san?"

Kimiko sat up, "Nice going Four-Eyes!" she growled, rubbing the back of her head.

"What did I do? What's wrong with Nii-san?" trying to get out of his older brother's grip.

"You tried to make him your mate, and he caught the scent of your blood which he is now trying to drink."

Yukio's now teal eyes went huge as he turned red in embarrassment, "I-I did what?!"

"You heard me."

He did, but couldn't believe it, 'I tried to mate Nii-san?!' feeling something on him stir at the thought which he tried to ignore.

As for Rin, it was his demon's turn to run rampant, 'Blood. Yukio's blood. It smells nice. Drink,' he thought, releasing his pheromones.

Yukio's eyes started to go foggy as he was hit by the wave of pheromones, "H-help," he tried weakly as Kimiko and Mephisto were standing up, "get him off of me," losing the will to fight.

The older demons saw Rin's fangs lengthening, and started removing him from Yukio. This was not an easy task as Rin was snarling, and clawing as they tried.

Yukio was hazy, "What's happening to Nii-san? What's wrong with him?"

Mephisto held the Lust demon by his arms as Kimiko tried to tame his kicking legs, "You're a teacher so you've probably confiscated a few books before," Kimiko says, Yukio nodding, "Well how do you think authors went from vampires, to use human terms, being creatures of horror to sex demons?" Kimiko asks.

Yukio's eyes widen, "You mean…?"

"Marilyn Ross…met a Lust clan demon, and everyone else dominoed from there," she nodded. (A/N: I looked it up, and Marilyn Ross is the first author to fully romanticize the vampire.) Yukio stared at his snarling beast of a brother as Kimiko yells at him, "Now close that wound before he kills us!" getting kicked in the gut.

Yukio looked horrified, barely able to comprehend the situation, but nods, listening to the demon voice in his head as he licks the wound closed, Mephisto trying to do the same for Rin's wrist while still holding his arms.

Mephisto sighs, finally just knocking him back out before grinning at a horrified Yukio, "Wonderful job Yukio-sensei~! Let's get the newbie Lust clan leader horny, then tempt him, excellent idea~!"

'Why the hell-,' Yukio thinks to Satan while also asking the two older demons the same thing, "-did none of you tell us this?!" 'What if this had happened in class? He could attack one of the students. If he did that then the Vatican would definitely have him killed!' the Doctor-in-training internally panics.

The two shrug, Satan making the cartoony shrugging noise, "We didn't know if he'd have blood lust or not only being a half-demon," Mephisto starts.

Kimiko continuing, "We didn't want to alert him to the possibility in case he got curious, and well curiosity killed the cat."

It was me who told them not to tell, I knew you two would be upset if he attacked any of your humans, trying to be fatherly.

"You idiots. Damn demons," Yukio growled as Rin groaned, starting to regain consciousness.

"Ow, my head… What happened?" holding his head.

Yukio blushed a little, giving the older demons an 'I'll handle this' look, and sighing when he decided to leave Rin to his ignorance, "What do you last remember?"

Rin blinks at Yukio, fangs gone and eyes back to their beautiful blue, "Koori told you to give me a command, and you said my name, the rest is blank," he says, looking around as Mephisto and Kimiko let go of him. Rin's eyes land on Koori, "What happened to yo-," he's about to ask before the previous moments events come back to him as is face turns red.

"Yeah, you happened or more like your brother happened," he growls, glaring at Yukio.

Rin rounded on his baby brother, "What the Hell, Four-Eyes?!"

Yukio stutters, "I-I can explain!"

"You made me kiss him?!"

Yukio blinks, "Is that all you remember?"

"Is there more?!"

"No," Yukio shrugs, "He pissed me off, told me to give you a command, and I saw the opportunity for pay back, and took it," he said like it was a no-brainer.

Rin's face turned red for a different reason now as red flames erupted from him, "Yukio, I would run," he growls.

Hehe! And he still may kill one of my children! Satan laughs as Yukio vanishes with a 'Gone Fishing' note left in his place.

"Yukio!"


Yay! New chapter! I'm so sorry the first one sucked again, but I hope you enjoyed this! This is still the longest chapter so far in the whole story racking in at 2,906 words, if you don't include the author's notes at the beginning and end. I had fun writing this chapter, and my writer's block has lifted so I'm almost done with Chapter 10! Woohoo! That should be up next week. I hope you liked the chapter! Please review to help make sure I'm never this bad again!
