Disclaimer: I am not RIB so no, I don't own GLEE or its characters :(

Story note: First off, this is only loosely based on Christianity and the only real mention of it is through Satan/the Devil. It has cannon elements to it, but it's weaved in differently. I have a whole entire head cannon on my 'verse and how the angels and demons work. If you have any questions, feel free to PM me or ask a question in the reviews :)

Author's note: Hey! This is my first official fanfic and I'm really excited about it! I'm a bit late on the whole angels and demons AU, but better late than never! I really hope you enjoy it and I'm open to any type of constructive criticism as long as it's friendly :)

Chapter One: The Lioness and the Debonair

Two students, a male and female, walk side by side down the congested halls of Lima, Ohio's William McKinley High School. The girl – a slender Latina – appears to be a cheerleader, walking alongside a stylish, charismatic young man with dark chocolate curls. One would insist that the two are boyfriend and girlfriend; the way that avidly talk to another, large gestures and smiles on their faces as they glance at one another. To assume that the two are together would only be natural. Normal. Realistic. But upon further inspection, you would realize that you are not only incorrect in your assumption, but the two are far from anything natural.

The lioness and the debonair.

Look more closely. You will find that these two students are not human at all. These creatures are angels. Fallen angels. Demons.

There was mischief in their eyes shine, causing the eyes to shine its true color. All light disappeared, leaving a cold, hard obsidian. The smiles on their faces reveal to be smirks: their reaction to the female's tale of her latest victim. They revel in her vivid description of the man's terror as she reveals herself. Catching themselves, the blackness in their eyes flashes away, fleeing as quickly as it came. The dark presence resides and the charms of their human eyes resume.

The male, although rather uncous, hides a vulnerable interior behind hate and spite. Every demon has a weakness, some lesser than others, but always they can avoid it. The boy, Blaine, however, is in love. It's blasphemy to the demon's very nature – love is weak, unnecessary, and disgusting. But Blaine has not always been with this evil nature. He has been with it long enough to be disgusted by these emotions and wants to do anything within his power to rid himself of it, though.

The mood changes as the two make a deal. A redemption of sorts, for our male. The offer appeals to him in a way that may possibly make him invulnerable and all powerful. Of course, he agrees. What he would not find, however, is how foolish and how grateful he would come to be for it.

"Ok, ok. So," Blaine pauses. He allows the words to linger on his tongue, assuring the girl's full attention. "If I am to agree to this – which I do, by the way. No way am I letting this go. But, Santana, what are the rules?"

Santana stops in her stride, tugging on Blaine's red cardigan for him to do the same. Students in the hallway flash by them, neither of them pays any attention, though. She smirks up at him, her eyes twinkling with a dark excitement. "You need to draw it out. It can't be quick, like what I did with Britt's. He has to fall for you. Hard. It might be a little tricky to start out, seeing that Berry blabbed on you as soon as she found out. But gain his trust. Pull out that little dapper man with the bowties and all his shining glory." She rolls her eyes. "But seriously, you can act, might as well use it." She heightened her voice, turning it mockingly sweet. The tone was disturbing, if not amusing. "Tell him, that you want to change. That you just can't stand to be apart from him! You don't want to do bad things anymore, that deep down, you know that you're a good person! That you're on," she sighs dramatically, hand clasping her heart, "the side of the angels."

Blaine chuckles, laughing at the girl's antics. "Leave it to you for all that dramatic crap. You're almost as bad as Rachel. I think glee club is having an affect on you," he teases.

The Latina scoffs, rolling her eyes. "Oh, please. I've been a cold-hearted bitch for half a millennium and I intend on staying that way. There is no way that I'll be some prissy diva."

Santana begins to walk away as Blaine catches her by her lettermen's jacket. She looks back at him, her face contorted in confusion as he smirks, "That's right. You're kind of old, aren't you."

She stares blankly at him. "Why, yes, Mr. 'I'm half a century man'."

His smile fades as recollection of his past birthday party comes to his mind. Blaine glares as he turns to grumbles. "You know I don't do well with alcohol."

Santana only snorts. "Oh Curly, trust me, I know. A drunk demon, – or no, a drunk Blaine Anderson – is a sight to be held, viewing with caution." Her playfulness suddenly disappears as impatience seeps into her smoldering eyes, her face fierce. "Now get moving! Angels don't fall themselves, you know."

And with that, Santana walks off. Her curvaceous hips swayed with her every step, confidence simply exuding around her.

Any man would salivate over her body. Her long legs, perfectly sculpted, disappeared into the short length of her Cheerios' skirt. Although her arms were covered by the girl's size-too-small jacket, they did not leave much to the imagination. It clung to the skin, revealing the defining muscle left from all those practice hours. Her chest was fully covered and the top hung loose just below her neckline, leaving the mind to draw in the figure. It made her all too tempting, as if she were flaunting her body, but only to jerk it back the moment one showed interest, leaving them all too eager for more. She was both the bait and the fisherman. But her most defining feature was her face. It was of natural beauty, without need of make-up. Her heart shaped face had a strong, yet soft jawline, in an almost feline manner. The Latina's full, pouty lips rested just above it, deep and lustful, but still natural. Her small, soft nose rose gently, then quickly faded as it climbed up her face. The arched eyebrows framed her eyes, making them appear sharp. The swirls in her irises mixed together, any and every shade of brown. It was both deep and lustrous. Her hair, true to her native land, held the brown of the trunk of a pine tree, verging on black like the dampened dirt around it. She positioned it in a high ponytail, allowing no loose strands to escape.

She was beautiful, alluring. But behind all that was something far more sinister. She uses her assets to its fullest potential as she stalks her prey. Then she waits for the moment to arise when she finishes her victim, ripping out its soul to deliver it to her master. Their master.

Santana was innately evil, yes, but she did have a small soft spot for her family. Seeing as she was on the darker side of the supernatural world, her family was lacking but those who were were held tight yet kept so far away. She both loved and distanced herself. Blaine, he was different. He loved someone he barely even knew outside of the small conversations in glee club. Kurt Hummel was nothing and everything to him. But after receiving a mate – Brittany Pierce, was Santana's – a demon, no matter the age, tends to slip slightly. That, and the years that Blaine and she have banded together, has brought the two of them close.

Dear Santana has no idea of the effect the angel, Kurt, has over Blaine Anderson. She has no idea that this could quite possibly break her only friend.

But Blaine doesn't mind. No, he is ecstatic.
