A/N Due to just how much attention my Subaru x Yui oneshot, Gentle, has gotten - and for how much I love the pairing. Here's a short, "five chapters at the most" multi-chaptered fic of the pairing. Again, there's such a lack of Subaru x Yui fanfics on this site that it saddens me. It's a travesty and I hope that those that ship Subaru and Yui like I do, can find my fic satisfactory to fulfill your shipping needs haha.

I'm not 100% sure if I'll make this M-rated with a lemon scene, but if you guys want one, I'll add it in. If not, then that's fine too. I have no qualms with writing smut hah.

Anyways, this is an AU (Alternative Universe) fic featuring Demon!Subaru and Angel!Yui. Pretty self-explanatory and cliched as fuck, right? Still hope this will be enjoyable for you lot.

Again, this fic will be pretty short, since I have two, ongoing large multi-chaptered fanfics I'm writing for another section that demands a majority of my attention.

Innocence, Unbounded

Subaru Sakamaki x Yui Komori short, multi-chaptered fic; Demon and Angel AU

Summary: He was a creature of sin and she was a being of purity. They were never meant to fall in love with each other, but Subaru couldn't help it. She had stolen his heart with her unbounded innocence.

Rating: T to M

Warnings: Possible lemon scene/smut, language

I.

Her Eyes

It was the first thing Subaru noticed about her, aside from the blooming white wings that spread out from her bare back.

Her eyes.

They were such a beautiful rose-pink color that reflected the purest of all innocence. He stumbled upon the angel by chance, unsure of what to do when her eyes met his. He simply froze as his gaze locked with hers. Her eyes were of such untainted innocence that drew him towards her like a magnet.

Subaru had seen angels several times in the past. While his fellow demon brethren would love to torment them, sometimes even go so far as to kill them and drink their untainted blood, he found no such pleasure in doing so. The few times he did run into an angel, he would ignore them or leave them be. Angels never interested him, that was, until he stumbled upon this one.

She had light blond hair that was gently waved and bounced just ever so slightly when she turned her head to face in his direction. The ends of her hair brushed against her porcelain, pale shoulders as a gentle wind stirred past them. Her eyes rested on his for what seemed like the longest time - the two of them trapped in their own little world for that brief second.

She was the first to move - out of fear. Terror filled those round eyes of hers as she took a wide step back. Her white, feathered wings spread out just a foot past her shoulders, readying herself to take flight. She then, escaped, before Subaru could do or say anything.

It all happened so suddenly that he simply stood there, the soles of his black leather boots rooted firmly to the damp, dirt ground. He knew that he could easily catch up to her if he wished to give chase, but he didn't. That was because Subaru knew that nothing good would come from any sort of relationship that would blossom between them, for he was a demon and she was an angel.

It took Yui several days before she willingly ventured out from the safety of the Haven. While she was an adventurous spirit, always curious about the world in front of her, she was wary about having another run in with a demon.

She spread her wings and soared through the skies aimlessly as thoughts raced through her mind of her encounter a few days ago.

He definitely was a demon - burning red eyes, black feathered wings, and pointed fangs that could be visible through slightly parted lips. It brought chills racing through her lithe body at the mere thought. The seraphims at the Haven always warned the younger angels to be wary of demons. They were all ruthless, violent creatures that wouldn't think twice of killing an angel and drinking their blood dry.

Yui's soft white wings trembled just slightly as she came to a gentle landing in a small clearing. She felt the tickling sensation of the grass brushing against her bare feet as she stood in the tranquil area for a while, lost in thought.

Surely, the demon wouldn't come seeking her out again - would he?

Although it was her first encounter with a demon, Yui found herself intrigued with how the white haired creature was looking at her. His eyes were colored a bloodthirsty red, but his gaze that rested upon her was anything other than that. She wasn't quite sure what his intentions were had she stayed there longer - not that she wanted to find out in the first place.

She caught movement in her peripheral vision, snapping her out of her thoughts. At first, she tensed up, but quickly relaxed when she saw that it was only a small bunny. A broad smile decorated her small face as she knelt down, coaxing the quiet baby animal to come over to her with sweet words.

"Come here, I won't hurt you," she whispered, giggling softly as the bunny hopped over to her. It gently sniffed the tips of her delicate fingers before hopping up onto her outstretched palm. Yui held the white bunny in her hands, petting its head a few times before letting it settle down in her lap. She blinked, growing still when she saw the bunny's round red eyes staring back at her.

It began reminding her of the demon she had encountered - the same bloodthirsty red eyes.

"...It can't be," she conceded with a soft, relaxed sigh. Her slender hand ran over the bunny's small body as it nibbled gently at her loose, flowing white dress. 'I'm just overthinking things and making myself paranoid…-'

Yui gasped as the bunny suddenly hopped out of her lap, as if it was startled. She drew back her hands and watched as the small animal ran away from her. Curious as to why it suddenly ran away, the young girl stared at it retreating into the thick forest until she finally felt the eerie feeling of being watched. Her pink eyes widened in fear as she turned slowly.

A thick, ominous presence weighed down on her fragile body. Yui nervously fluttered her wings as her eyes finally locked on to bloody red ones. A frightened, silent gasp escaped her as she backed away.

It was him again - the white haired demon.

Everything pissed him off to no end - his obnoxious brothers, their always absent father, and his mother, who always told him to get out of her sight during her manic episodes. So, Subaru did just that during her most recent episode.

"Damn it," he growled under his breath, slamming his fist down against the nearest tree and nearly splintering it in half. His teeth clenched in anger. He hated how he was always treated like a monster - an outsider, even amongst the other demons. Despite his father being the king of demons and his mother being regarded as one of the most beautiful of succubi, that didn't warrant the other demons from giving Subaru any special treatment.

He rarely spoke to others - being that he wasn't an eloquent speaker like his older brother Reiji or a talkative, chatterbox like Ayato. He assumed that this type of aloof behavior came off as arrogant to the other demons, which instigated many violent fights between them and Subaru. It was tough, but he didn't complain.

He didn't need anyone - ever.

Or at least, that's what he thought.

Subaru grew still at the sound of a young maiden's voice. He stopped walking through the dense forest, where he normally came to get away from the rest of the demons, and stood there - listening intently.

It was a soft giggle, the most innocent one he could possibly hear. It sounded like a beautiful melody to him as he quietly edged closer to the owner of the angelic voice. The trees thinned out and finally, he came to a stop at the edge of a small clearing, where he saw her - the angel he had seen a few days ago.

She was playing with what looked like a small bunny in her lap. He stood there, staring at her, before subconsciously moving one foot forward. Subaru drew back when he saw the bunny turn its head over towards his direction and immediately flee from the young angel. He cocked his head to the side, wondering if she even noticed that he was only a few feet away from her.

It seemed as though she had answered his question when she finally turned around to face him, her beautiful pink eyes widened in terror at the sight of him. He noticed her wings fluttering softly, hesitant on escaping from him.

It was him that spoke to her first -

"Go."

"...Eh?" she breathed out softly, searching his face for the lie. Had she heard him correctly? "G - Go?" she stuttered.

"I have no interests in harming or maiming angels, however, I can't speak for the other demons should they find you here out in the open like this." Surprisingly enough, Subaru saw the most indignant look take over her face. He let out a sharp scoff and crossed his arms over his chest. "Aren't you leaving?"

Instead she continued to stare up at him with those beautiful gem-like irises. Finally, she asked him, "why are you letting me go?"

"Do I have to have a reason?" he grumbled.

The blond angel quickly shook her head. "It's just...how do I know you won't just chase after me the minute I take flight?" She seemed to be warily eyeing the large black wings on his back. "...I'd like to make sure that I'm not being lied to."

"I just told you my reason in the beginning - "

"It's a lie," she retorted.

Subaru clenched his jaw, starting to get irate with this angel. "How do you know whether I'm lying or not, you foolish girl?"

She brought herself up onto her feet, almost as if she was challenging him now. With a determined look in her docile pink eyes, she told him in a calm voice, "because we angels can see the truth in someone's eyes. ...You want me to stay, don't you?"

His red eyes widened in a fury as his hand shot out to grab her thin wrist. He heard her let out a surprised cry in response and attempt to pull herself away from him. Upon hearing this, his anger broke and a smirk crossed his face. "What does it matter if I want you to stay or not? You're scared of me aren't you? Just like everyone else - so why don't you just go when I'm giving you the chance to save yourself?" Subaru chuckled when he saw the all-too present fear deep within her eyes. "You're a foolish angel - "

Her eyes shot open wide when she saw him lean in closely towards her. "N - No!" she cried out, attempting to hit him across the face with a fist before he caught it in his other hand.

"You should've ran when you got the chance," Subaru whispered dangerously, causing the young angel to shiver in fear. "You think demons are to be trusted?" he questioned her, "I'm aware that angels are creatures of innocence, but that's naive thinking, even for the likes of you."

"It - It isn't naive…"

"...What?"

"It isn't naive - it's the truth," she answered him, mustering up all the courage she can to even properly speak to him. "Everyone - even demons - have some good within them."

Subaru narrowed his eyes at her, thinking back to the demons that resided in the underworld and how they loved to torture captured angels and even mortals. It was immoral cruelty and it was something that Subaru could never feel comfortable with, even as a demon himself. "Don't speak as if you know everything about us." He gave her arm a sharp yank, making her crash into his chest.

She let out a frightened gasp and shivered when he grabbed a hold of her jaw, forcing her to look up at him. Her eyebrows were furrowed in a look of panic.

Subaru stared at her hard before breaking out into a sneer. "...This is your first time encountering a demon, isn't it?"

She remained silent.

"...So how is it that you're able to say with full confidence that we demons have a good side? We're all rotten, filthy, sinful creatures that feed off of fear and pain." Subaru released her suddenly and snapped in a sharp tone, "now get out of here, unless you want to be discovered by another demon. "

The blond girl started at him for a while before telling him, "then can I say that you have a good side at least?"

He stopped walking away from her and turned his head sharply, just to glare at her. Subaru saw her flinch slightly from his fearsome gaze. "I'm just as rotten and filthy like the others, perhaps even more," he told her, turning his back towards her.

"You didn't kill me though."

" Killing you is like killing that defenseless bunny you were playing with earlier - it's pointless bloodshed and I don't harm those that can't fight back. ...That's all," he responded, intending that to be his final parting words for her. That was, until she decided to speak once more.

" - Then you're not rotten and filthy like you claim to be."

Subaru stopped in his tracks. He parted his lips briefly, wanting to answer her back, but instead he sealed them.

How was it that a naive angel like her could see right through him?

A/N So! Like it, love it? Tell me in a review! :) I'll make the next four chapters longer since most of my first chapters are just hooks and a tester to see if people like the fic or not.

While I like incorporating a deep plot and a theme to my stories, this is probably just going to fluff (and maybe smut) between these two. Sorry to say, but there will probably only be mentions and very short appearances of the other brothers. This is 100% Subaru and Yui oriented, so no annoying OCs either.

'Til the next chapter!
