The Morningstar's Guiding Light

It was the morning of Ky's birthday, the sun barely lit Lucifer's room from the blockage of the curtains. The large master bedroom, filled with a large king sized bed, one that held the two lovers wrapped up under the nice velvety sheets, keeping them warm in the cold room.

As Lucifer's alarm rang throughout the room, the extremely tired and barely awake demon reached out, shutting the alarm off and wrapping his arms around his equally tired human, neither of them were fans of just waking up in the morning, but today, especially for Lucifer, they weren't mad. Lucifer’s head rested in the crook of Ky's neck, his arms wrapping around his lover's body in a protective and close hold. Once he spoke, his voice sounded groggy and dazed, though the happiness in it was audible.

“.. Happy birthday, my angel…” Lucifer says and sounding somewhat muffled with his mouth covered by Ky's shoulder. Lucifer's ears can almost be seen twitching for a second as he hears the very groggy voice of his human, even if it was his birthday, he's still cranky, he wasn't a morning person, the same way Lucifer wasn't a morning demon.

“mmmm.. Thanks Luci..” Ky says groggily before lifting himself up just barely to give Lucifer a kiss on the cheek, a small, tired smile, playing on his lips. Though, knowing how Lucifer was, Ky almost immediately felt Lucifer's hand under his chin. Luci's fingers gently tilted Ky's head up, their lips connecting into a warm and passionate kiss. Though their fun alone didn't last too long.

The two heard the little taps of feet running down the quiet hallway in the House of Lamentation, along with some long strides behind the littler ones. The first to barge into the room was Kenji, with his elder sister, Katsumi following behind him, looking as tired as her parents, unlike Kenji she definitely took after her parents with not being a fan of waking up so early in the morning, Kenji on the other hand, was as energetic as he could be, being as young as he was it's no wonder. After running in, Kenji hopped up on Lucifer's bed, giving both of his dad's a very excitable and warm hug each, both of them hearing the excitement in his little voice as he spoke. “Happy birthday, papa!”

More close by, Kat walked inside behind Kenji, her tired voice faintly echoing through the otherwise quiet and empty hallways with a soft yawn as she spoke aloud as well. “Hmmm… Happy birthday, papa..” Despite how tired she was, the happiness she had was audible, to which Ky smiled gently at the two, ruffling up Kenji’s hair as he spoke. “Awh, thanks so much you two… I appreciate it”

After a moment Ky, Luci, and Kenji got out of bed and followed along with Katsumi to the kitchen, where to none of their surprise, could all hear the bickering of Lucifer's six other brothers in the dining hall.

“Hey! Beel! I told you not to eat all of the waffles!” That was definitely Satan, which promptly had a follow up from Beel. “I'm sorry… I was hungry..” Asmo chimed in with a reply of his own almost immediately. “Beel, hon… You're always hungry… How about you set the table instead, hm?” He suggested, Beel simply replying with an ‘Okay’ and Belphie tiredly following behind him. Mammon and Levi were just barely walking out of the kitchen with a new serving of waffles, alongside other breakfast dishes, pancakes, French toast, milk, orange juice, fruit, whipped cream. They all had practically made a feast together, though of course with the casual amount of familial fights that they quickly recovered from. “Hey! Beel! Don't eat these either, ya got that? I ain't makin’ more of these get eaten too!” Mammon said with a mock-scowl, placing the food he had on the table, Levi following behind him with his usual snarky replies. “LOL! Come on, Mammon, you'd make it again for his birthday, we all know you would!” Mammon's cheeks flushed red in embarrassment, though he just barely missed dropping the bottle of whipped cream. “H-Hey! Shut up will ya?! I wouldn't! All of ya can make it yourselves if it falls!” Mammon snapped back, taking a seat down at the table.

Mammon soon after however, looks up from his seat, seeing the other four in the distance and about to walk in, he had an almost devilish smile on his face, getting up from his seat to greet the birthday boy himself with a real tight hug, partially to get under the rest of his brother's skins, and they knew it all too well by that point to even care. “Hey there! Happy birthday Ky! How've you been so far, huh? Better be good or else I'll give Lucifer a good talkin’ to for ya!” Mammon caused a few laughs from Ky and especially Katsumi, she had always found her uncle Mammon to be a riot, getting a warm hug returned to him as well from the little human. “Hehe, it's been great, don't worry about it you big goof..” Ky says with a grin as the rest of the brothers approach him, a jokingly loud sigh from Lucifer in the background of his brothers usual morning antics, he had once again, underestimated how willing his brothers were to wake themselves up before even he got out of bed, just to surprise his human, something about it made him feel content within that chaos.

“Mammon move your ahhh- I mean butt out of my way! You're hogging Ky and you know it!” Levi snapped, only causing Mammon to stick his tongue out at his brother, who rightfully gave him a dirty scowl.

“Awh, Hon, how about I get your breakfast for you! Do you want Waffles? Maybe some fruits too? and some sweet whipped cream?” Asmo coo’s, subtly trying to outdo Mammon without being as forward about it, Belphie slipped through the others, his hand grabbed onto Ky's arm, holding his comfortable pillow out to him.

“Mmmm… How about you take a nap with this? It's comfy you know.. and it is my favorite, so you better return it by tomorrow..”

Soon after came Satan, a small pair of what seemed to be handmade cat plushies in his hands, his face looking flushed with embarrassment at the stuff he'd made and handed to Ky. “Look.. I.. I made you these of you and Mr. Pridy McPrideFace. Don't let them get ruined, you hear?” He said as he crossed his arms, Asmo looked like he was about to squeal but kept himself quiet and gave an excited smile to Satan.

After a while, Levi was able to get through the oddly rough crowd of 5 other demons in his way, though after seeing Satan's gift his cheeks got the same level of red to them, maybe even worse knowing how he was. “I- I uh- Listen I know Satan made you those and all but I found this custom acrylic thing on Akuzon and uh… got you a few!” Levi would've practically shoved the gift box of acrylics in Ky's hand if he wasn't aware of how ruined it would make the stands, so he gave it to him gently.

Then Mammon, having almost forgotten, pulled a pair of tickets from his pocket, handing them to Lucifer, knowing My would more than likely lose them in the mess of gifts in his hands, he then looked back at the human before speaking to him, seeing the shocked look on his face, though he couldn't tell if it was from his gift or the mountain from his brothers. “Listen, short stuff. I got ya two tickets to go to Devil's Coast.. I figured tomorrow you and Lucifer can… I don't know.. go or somethin.” Mammon had the most embarrassed look to him yet, though the other 5 behind him looked shocked, then Lucifer chimed in as he stared almost blankly at the pair of tickets in his hands.

“Mammon,” he started, his voice having that same sharp edge to it that would always make his brothers, and sometimes his kids, scared shitless. “Where did you even get the money for these?” Thankfully, for Mammon, he didn't buy them completely recklessly. “Well uh, y’see big bro… I was able to get them from this super nice witch who had two spares, just hadda pay her upfront!-” “And how did you get the money? I thought it was suspicious how often you haven't been home as often, you know.”

Ky, having to listen in on this along with the rest of the brothers, spoke up with his own assumption. “He probably just worked overtime to not have a loan.. If that's all it is, don't worry so much about it, love.” Ky basically gave his demon the look of, ‘don’t ask, just roll with it’ and he reluctantly agreed, Mammon looked as if he'd just been saved.

Then finally amidst the chaos, Beel stepped up, holding a coupon in his hand, also like Mammon, he handed it to Lucifer, though he looked like he was about to start drooling, and once Lucifer saw what the coupon was for he could immediately see why. his hand held a coupon for Ristorante Six, how Beel didn't use this himself? He had no idea, but he didn't bother asking, though he heard Beel whisper in his ear to tell Ky the gift was from him later, to which Lucifer nodded and placed the two tickets and the coupon in his wallet, keeping them safe in his pocket.

“Here, Ky, let me put these in our room.” Luci said, holding his hands out for the oddly large set of gifts, which Ky almost immediately gave him, his arms already getting tired from holding them all, as Lucifer walked away he group hugged the rest of the brothers, a goofy ass smile the brothers knew him for across his face, showing he definitely liked the gifts at least.

The large group soon after took their seats at the large table in the room, eating breakfast together and engaging in their usual familial banter and talking. As each of the brothers and their kids finished their food, they excused themselves, Katsumi and Kenji both grabbed a pair of gifts they'd kept in Kat's purse, since it was oddly a giant purse, Kenji had a small card in his little hands, having a little personally written message from both his kids and even Lucifer as well inside it. Katsumi had her half of the gift, having gotten her artsy hobbies from her dad. She wanted to make him small plushies, so she made a whole little set of plush keychains of each of them.

Ky's face was nothing short of pure shock at everything he saw, and of course, in fashion of his human relatives, he slowly got teary eyed reading the little messages from his kids and Lucifer, and of course Lucifer’s was most of the entire second half of the card, leave it to him to ramble about how he loved his human, even to his face. In writing or verbal speech, he made sure his feelings were always known. The day itself was filled with fun shenanigans, each of the other brothers and the kids distracting Ky until Lucifer was ready with his surprise to finish the night off.

As the day was nearing its end, Lucifer sent Ky a message, a quick one to make him move to him faster, the demon was almost craving to spend time with his human and he planned on making it worth the wait for both of them.. Once Kyro walked into the bedroom, Lucifer stood, all dressed up just for him, the sight could almost make the guy tear up again at the thoughtfulness.

“Are you ready to go, my little love?” Lucifer spoke, his voice filled to the brim with the tender warmth Ky knew all too well. “I've planned something special for you.. I know you won't forget it.”

Ky smiled at Lucifer’s words, nodding his head and holding his hand out for the demon to take, which he promptly did, “Yea, I'm ready. I'm really excited! I've been wanting to spend time with you all day…”

The two of them took hands and made their way to the car, Lucifer had a whole day's worth of activities. They went to many places throughout the day, from cafes, to parks, to stores, pretty much anywhere. They had the day to themselves and they'd take full advantage of that. Though as a final tribute, Lucifer thought of bringing Ky to the Devil's Coast, and go on the Ferris Wheel, the same place he proposed to him, making it a special place for the two of them. After getting to Devils Coast, Ky looked ecstatic, like his suppressed inner child got released. Seeing how expressive Ky can somehow get despite all Lucifer knows about him, it made him smile, all that excitement was because of him, it made his pride swell up when his love enjoyed his surprises.

“I'll get the door for you, love.” Lucifer said as he was getting out of the car, swiftly making his way to the passenger side of the car, opening the door and helping Ky out, his actions causing his humans cheeks to redden, which was his end goal, not like it took much work on Lucifer's end to make his human flustered like that anyway, saves him all the trouble.

The two of them had a fun night out at the Devil's Coast, they got one last meal at one of the local food stands for their dinner, played a bunch of the corny carnival games with Lucifer pretending he was some hot shot and could win each one with no effort, they walked along the beach before the sun started to fully set and then after getting ice cream, they went on the Ferris Wheel.

They engaged in some mindless chatting about Ky's day while the ride started up. Lucifer was just glad he could make his human happy, he adored seeing Ky smile, he'd never admit to it but he'd do anything to see it on him. As the Ferris Wheel started getting up to the top with the sunset looking almost mesmerizing from their view, Lucifer turned Ky to face him by the window, cupping his chin in his hand, slowly pulling him in for a tender kiss. The sun's rays were practically reflecting on the two as they shared their kiss, and once they parted, Lucifer could see the pure shocked and flustered expression on Ky's face. He felt pride swell up at Ky's reaction to him, letting out a soft chuckle.

After the two finished their ride, going inside and getting settled in bed, they continued talking in bed, Ky's eyes slowly getting droopy, being exhausted after such a long day.

“Did you have fun, my love?” Lucifer asked, his own voice having that same tone of exhaustion after a long work day, though the hint of a smile on his face, he had a good time and wasn't afraid to show it.

“Hehe.. of course I did, I loved it.. Thank you, Luci..” Ky said as he snuggled himself close to Luci, wrapping his arms around the demon's body, keeping them close together.

“Good… I'm glad”

After Lucifer spoke, the two were out like a light, snuggled up close, the two celebrating the final hours of Ky's birthday cuddled together, Lucifer holding his human close to him as well, never letting him go.
