"This is me." Loona announced with a smile as she and Fenrir came to a stop outside of the I.M.P building, their coffees long drank and discarded in the trash. After Fenrir had wished her a happy birthday, the two continued to walk, with Fenrir remarking that 'why walk alone when you can have company?'. And Loona didn't mind walking with him. She'll look for any excuse to at least keep talking to the super hot Hellhound that was really piquing her interest and wasn't perving on her like a total creep as most of the guys she's met do.

"This is where you work?" Fenrir asked, looking the building over and humming slightly.

Loona blushed a little. "Y-Yeah, it's, uh... not exactly modest."

Fenrir snorted and Loona couldn't help but giggle. Both of them knew what they were thinking; it's Hell. Nothing is modest.

"Well, would the birthday girl mind if I escorted her up to her office?" Fenrir asked, turning to her with a smooth smirk and crossing his arms over his chest. Loona had to stop the urge to lick her lips as she eyed his muscles and muscular chest.

However, he asked a question and she sure as hell answered. "N-No, I-I wouldn't mind, really." Loona laughed lightly, brushing some of her hair away from her eyes. "J-Just... be prepared to meet my... coworkers. They're annoying little shits, especially Fatass."

"Fatass?" Fenrir raised a brow but didn't breach that subject any further as he grabbed the door handled and opened it for Loona, who walked in after sending him a small smile. As they walked towards the elevator, the male Hellhound was mentally going through his thoughts.

Okay, Fen, you're talking to an incredibly hot girl, she hasn't blown you off and clearly likes talking to you. Maybe... maybe I should ask her out? No! No! it's her birthday! It's her day. But maybe I can do something for her. Fenrir nearly grumbled to himself. He wasn't experienced in this. He's never had a girlfriend. He's been with women, but never has he actually had a relationship.

As they entered the elevator, Fenrir saw a board with the floor levels and names of companies on each floor, one of which made him raise an eyebrow.

"I.M.P. That's the assassination company with the weird, but oddly catchy, jingle." Fenrir stated, having watched that jingle once on TV.

Loona looked at him, surprised. "You watched that shit?"

"Hey, the jingle was catchy." Fenrir shrugged his shoulders. He then shifted nervously, mentally praying that he had his father's luck... and that was pretty ironic considering his father was the Devil. "So, uh..."

Loona side-eyed him. "So...?" She pressed.

"You... you wouldn't mind company tonight for your birthday plans?" Fenrir asked a little anxiously. Oh fuck, he was so terrible at this. Dad always said be honest with women, it's how he earned a place in Lilith's heart. "I-I mean, we-we're friends, right?"

They came to a stop at the door leading to I.M.P., Loona staring at Fenrir with wide eyes. "Are you asking me out?" She asked, tone neutral, making him unsure of what she was thinking.

"I...um... fuck, I'm so terrible at this." Fenrir muttered into a clawed hand which he dragged down his face. "It-it doesn't have to be a date, if-if you don't want it to be. I just thought... because it's your birthday, you'd... you'd want to spend it with someone while having fun." His eyes widened as he realized what that couldn't meant. "N-Not that kind of fun. I meant... fuck..."

As the Prince of Hell literally stumbled over his words while clearly trying to find a reason to spend more time with the hot Hellhound before him, Loona simply watched him with a small, growing smile. She may not be a people person, sociable, or have much friends, but this guy? He was growing on her. He was hot, and the way he was clearly trying to ask her out without offending her was really cute. He clearly hasn't asked a girl out in his life, which surprised Loona as she figured he would've been in many relationships before.

Just as Loona went to open her mouth, the door opened and Moxxie stuck his head out, looking a little confused when he saw Loona and a male Hellhound. "Loona? What are you doing here? I thought you had the day o-OH MY SATAN! You're Fenrir Morningstar!"

Sure, shout for the whole fucking building to hear. Loona thought with a mental scoff in her head, feeling a little embarrassed that Fenrir had to see this. See what she had to put up with.

Fenrir merely stared at Moxxie, then looked at Loona. "This the one you call 'Fatass'?" He asked, amused. Loona couldn't help but grin as she looked up from her phone.

"Mox, why the fuck did you shout?!" Only for that grin to fall the second Loona heard the voice of her adoptive father. Her expression went to one of mortification as Blitzo ran over to the still open office door. He leapt up mid stride with his arms outstretched and a freaky smile on his face. "Loony! Baby girl! I knew it, you wanted to spend the day with dad–!"

There was a solid thump as the office door slammed shut before Blitzø could cross the threshold. The shadow of his face impacted the company's logo from the other side. Loona blinked and looked at Fenrir, whose hand was still on the door handle. He met her gaze, looked at his hand, and then looked back up.

"What? He's an assassin who jumped at us. Who the fuck knows what he was going to do?" He said.

Okay, it was 100% officially, fully confirmed.

Loona liked this guy.

She smirked and, without caring for his reaction, fished into his coat pocket and took his phone out much to his surprise before she quickly put in her contact details while also taking his own for her phone. Once she was done, she handed the phone back to him and smirked at his stupefied expression.

"My phone number's on there. Could you pick me up at seven?" She asked.

Fenrir pocketed his phone and grinned, showing his teeth. And when he spoke, there was a bit of a low rumble that Loona will not admit to anyone but herself... but it turned her on. "Seven sounds good. See you tonight."

Their... date? confirmed for tonight, Fenrir turned and walked back towards the lift, his tail swishing side to side as an expression of his mood and Loona couldn't stop her own from wagging happily. She had a date! She had a date tonight! On her birthday! With a incredibly sexy Hellhound who was also the Prince of Hell!

Oh God, she was going on a date with the Prince of Hell...

Take that, Vikki! 'Lunatic' Loona has a date with the Prince of Hell and it's her birthday!

Life is good for Loona.

"Okay. I look nice, smell nice, got a neat ride. I look fine." Fenrir muttered to himself as he pulled up outside of Loona's apartment - she had texted him the address earlier - on a black Harley-Davidson chopper that he had been given for his 18th birthday. He doesn't go everywhere with it, but this seemed like a special occasion to bring it out.

God, he hoped he wasn't trying too hard to impress. He had gone for a casual look but still maintaining the fact he was on a ... date? Or at least going out with a girl for her birthday.

Kicking the motorcycle stand out, Fenrir got off his ride and made his way into the building and up the stairs. About five minutes later, he arrived at Loona's door. Before he knocked, he quickly made sure he smoothed himself over, checked his breath - which smelt nice - his scent, his clothes, everything.

"Okay... okay..." He muttered to himself, then knocked on the door.

"Just a minute!" Loona's voice called from inside, and he heard footsteps running towards the door before stopping. A couple of seconds later, the door opened and Fenrir's breath was blown away as he stared at Loona.

Her attire could only be described as a gothic biker chick look. She wore knee-high gothic biker-style boots with buckles and heels, wore her new type of leggings that had fishnets, but they weren't see-through or anything. They still maintained her goth look. She wore black short shorts with a red belt holding them up. She also wore her crop top with the added addition of a short black jacket that barely came down at her sides. Her hair was neat brushed and flowed down her back, and her tail swished and swayed smoothly.

Fenrir did nothing but just stare with wide eyes and his mouth agape, causing Loona to blush while holding back the urge to run her hands through her hair. What did he think? Did she look amazing? Was she coming on too strong with her look?"

"S-So?" She asked meekly, not meeting his eyes.

"...You look fucking beautiful." Fenrir breathed, looking at her like she was the most beautiful creature in all of Hell, and that look along with his compliment made Loona's cheeks heat up while her stomach did flips and turns.

"T-Thank you." She quickly took out her compact mirror to give a last few-seconds glances at her appearance, making sure her hair was fine and all. "You look quite dashing yourself." She stepped out of her apartment and closed the door, locking it and then turned to him. "So, we ready?"

Fenrir nodded and they made their way down to the front of the building. Upon seeing the motorcycle, Loona let out a whistle, impressed.

"Sweet ride." She complimented while running her hands along the saddle which was at least big enough for two people. "You have this and don't drive around in it?"

Fenrir shrugged. "Teleportation can be faster." He got on the saddle and shifted so there was space for Loona, then handed her a helmet. "Here. I don't wear a helmet, and I doubt you want your hair ruined from the wind whipping by."

Loona snorted. "Got that right." She put the helmet on before swinging a leg over to sit down behind him. Her arms came around his waist, and she couldn't help but subtly run her claws against his toned stomach.

At least, she thought she was subtle.

If Fenrir knew what she was doing, he didn't acknowledged it as he kickstarted his ride. "Hold on." He advised, then shot off down the street.

"I'm not gonna lie, I thought you were gonna go all out in an effort to impress me - not that you aren't already." Loona chuckled sheepishly as she sat at a booth in a dive bar with Fenrir.

The two of them were at a diner in Pentagram City. One of the best, actually, as it's where Fenrir liked to go when he wanted to go out for the night. Had great food, not too expensive taste, and it wasn't a frequent spot for shitheads like the Vees. But then again, he had practically made it clear this was his frequent place to go to after having to beat up some Sinner fuck a few years ago when he was seventeen. And since then, nobody causes trouble in this place when he's around.

And it helps that he is always given the best booth in the house. Nobody dares take it. The owner of the diner makes it clear the booth is owned and forever claimed by the Prince of Hell.

Fenrir snorted at Loona's words, hardly offended. "You mean take you somewhere so luxuirous and expensive and almost brag about how rich I am and my status amongst the denizens of Hell? Nah, I wouldn't do that. It's your birthday, we only met a few days ago, and I thought it would be nice to at least take you out to... birthday dinner?"

Loona stared at him for a moment then smirked. "Or because you are inexperienced in taking a girl out."

"That... yeah, that's entirely truthful and accurate." Fenrir mumbled, earning a light chuckle from Loona that made him smile a little. "But, I ain't coming off too strong here, right? I mean, I'm not making you uncomfortable or-"

She wrapped her hand around his muzzle, stopping him from going on. "You're doing fine." She assured him. "I... I should be the one who's nervous. I mean, I don't have a lot of friends, I don't really go out unless it's to get shitfaced. And the few so-called 'dates' that i've been on... well, those guys were just wanting to get in between my legs and fuck me. Literally within the first five minutes."

"Rough. And this is the fucking Pride ring." Fenrir nodded. "Guys like that should be down in Lust, where uncle Ozzie would have them working. Maybe for our second date I'll take you... oh fuck..."

"Second date, huh?" Loona smirked at him. Was this a date?... Yeah. Yeah it was. A date with a stud on her birthday. And he's decent. Isn't a creep who's tried to get handsy with her or try to seduce her into fucking him. She patted his wrist. "Pass this one with flying colors and we can talk about a second date."

Fenrir looked at her, surprised she'd ever consider a second date with him, but he couldn't stop his tail from swishing happily much to Loona's amusement as she giggled. They picked up their bottles of whiskey and clinked them together.

"Happy birthday, Loona." Fenrir said.

Loona's tail just wagged happily.

"I can't believe this! I can't fucking believe this!" Blitzo snarled and raged as he pace in front of Moxxie and Millie, who were watching their boss in both annoyance and amusement respectively. Neither were really fazed when he glared at them. "You twou could've done something!"

"Like what?" Moxxie threw his hands up. "It was Fenrir Morningstar! The Prince of-"

Blitzo got right in his face. "I don't give a fuck if he was KING OF FUCKING EARTH, YOU FUCKING DIPSHIT! He's snatched my Loony-toony! And I know he'll do... nasty things to her against her will! He's probably doing it right now while she's screaming and yelling for daddy to come save her!" He stomped over to the mural of security camera stills that had red circles around the head of Loona's new friend. His arms crossed. "i'm gonna find this fucker! I'm gonna put so many holes in him, and them I'm gonna fuck each and every single one of them, Starting with his asshole!"

Moxxie sighed and looked at his wife. "We've lost him."

"I don't understand what the problem is, Blitz." Millie frowned, crossing her arms. "Loona's an adult who can make her own decisions. It's her twenty-second birthday. Let her have this!"

Before Blitzo could turn his wrath - ironic, considering Imps populate Wrath - onto her, a man's wail came from Blitzo's ass. "That's Loony-Toony's text scream!" Blitzo frantically pulled his Hellphone out, in his rush it was thrown across the room and he shrieked. "No! What if she needs help?! She might have to hide his body after he tried to force himself on her! I never got to body disposal lessons with her!"

"Sir, just read the message." Moxxie sighed into his hand while Millie giggled at their boss' overactive imagination. Her daddy was the same way whenever she or Sally Mae brought a boy around the farm.

"Oh, why the fuck didn't I think of that–I can't! It's a fucking picture, shithead!" Blitzo hissed, holding his phone out to them. In the picture was, obviously, Loona with some ruffled fur and her eyes looked a little unfocused. She was still clothed, evident by her crop top, though it was unknown if she was wearing anything lower. But what was the most attention-grabbing part of the photo was that she was laying on the bare chest of the Prince of Hell, who was out cold.

A man's wail emerged from the phone and Blitzo quickly turned it around. His eyes went wide and he started to clench his hand around the phone so hard it began to crack. Millie shared a look with Moxxie and they nodded. They had to save their boss' phone and see that new message.

"Sir, we can't afford another phone incident. So, may I-? Thank you." With a few tugs, Moxxie plucked the phone from Blitzo grasp. He and Millie guffawed at the message that had followed the image.

(Can I keep him?)

"I want... his head!" Blitz shrieked. He drew his flintlock and ran for the door. "Daddy's coming baby girl!"

Moxxie and Millie shared a look, both of them horrified, before they took off after their boss before he could go and attempt to murder a member of the Royal Family. Just even attacking a member was punishable by death! Furthermore, if Blitzo did attack the Prince, then Moxxie and Millie would be given a death warrant by association!

"Sir, don't!"

"Blitz, just calm down!"

"DON'T TELL ME TO CALM DOWN! I'M GONNA FUCK THAT FURRY BASTARD IN WAYS THAT WOULD MAKE HIS MOTHER WISH SHE GOT THE SAME!

"And now he's insulting Lilith. We're gonna die, Millie."

"Not if we don't stop him!"

And that's it for this chapter. FYI, expect a Fenrir vs Blitzo fight in the next chapter that may appear a little similar to a certain fight scene in Deadpool vs Wolverine, sans the beginning dialogue.

And just to tell you, there may be a chance of Helluva Spawn returning without changing anything in this story. I know I keep going back and fourth with decisions, but Spawn is my favourite Anti-Hero outside of Marvel and DC, so excuse me for wanting to do a lot of stuff that could feature my OC Hellspawn.

If I do bring Helluva Spawn back, which I am leaning towards doing, it will be OC x Loona x Verosika as before, and don't worry about Hell's Hellhound Prince. This too will stay the same way since both stories will be relatively different of course.
