A/N: Here is the final chapter of Let Me In. I hoped everyone enjoyed the story as much as I enjoyed writing it. As always, I do not own Beelzebub or its characters. Just this plot.

Beta read by Ashley Silver, formerly jneth1lary88.

Recap:

"So I guess this is the end of this threat." Furuichi stated as he watch Oga, Hilda and Beel.

"No." Lamia said also watching the trio. "I have a feeling this is only the beginning of something even bigger."

Furuichi raised an eyebrow at her statement but, deciding against questioning her. They would cross that bridge once they got there. They both began the journey home as well, happy that everyone was returning home unharmed.

Happily Ever After... For Now

Two months had passed since they had gotten Beel back. Not much had changed since then. Hilda still slept by Oga's side at night, something Beel was more than happy about. They never changed how they treated each other either, never hesitating to show each other affection.

They had decided not to return Beel to the demon world right away, opting to instead keep him for a few days. Most of the time was spent together with the infant. When they eventually did bring him back to the Demon world, they were surprised by what had occurred. Instead of taking Beel back, the Demon King had instead given Oga and Hilda an apology, saying that he was tricked into thinking they were not good parents by Solomon Company. He then surprised them again by officially naming them as Beel's mother and father, giving them full custody of the Baby Demon Lord. Hilda was overjoyed, as tears formed at the corners of her eyes and as for Oga, well he was happy as well though he only showed it through the smile on his face. After that everything settled down as life seemed to return back to normal.

Currently the three of them lay on the bed in their room, fast asleep. Beel lay in his usual corner, nearest the wall. Hilda was in the middle of the bed, snuggling up against Oga's left side as her head resting on his chest. She was wearing one of Oga's black tee shirts that landed mid thigh on her. Oga always questioned her why she wore his shirts, but she always told him that she liked to wear things that were comfortable.

It was a Sunday so there wasn't any school. It wasn't long before Hilda stirred first. Blinking the sleep out of her eyes, she sat up and stretched, the movement causing Oga to stir as well. Once she had finished stretching she laid back down onto the bed and turned onto her right side as Oga turned onto his left. Wrapping his arms around her, he pulled her close as they shared their usual morning kiss.

"Morning Tatsumi."

"Morning Hilda." They both whispered to each other as they rested their foreheads against one another's. They stayed like this until they heard Beel stir. Hilda then turned over to her other side and pulled Beel into a hug.

"Good morning Beelze" Hilda greeted sweetly while Oga ruffled his hair. It had taken some time for her to get used to calling him by his name rather than young master, but eventually over time, it became almost second nature to her.

"Da" Beel said while he rubbed the sleep out of his eyes with his little hands.

With everyone awake they decided to get up to have some breakfast. Oga pulled on a white tee shirt before picking up Beel and walking to the door. Hilda got up to follow him, but stopped when she suddenly felt light headed. She placed a hand on the desk to steady herself, but the feeling disappeared as quickly as it appeared, so she played it off as nothing and caught up with Oga out in the hallway, as they made their way downstairs. They entered the kitchen and noticed that everyone else was awake as well so they put Beel in his highchair and gave him his bottle before joining Misaki and Mr. Oga at the table. Just as they sitting down, Mrs. Oga,came from the stove with a plate full of food for both of them. She handed them both their plate's before joining everyone else at the table as the couple dug into their own plated respectively. Halfway through her plate, Hilda started to feel sick to her stomach and before she knew it had dropped her chopsticks and sprinted off towards the bathroom.

Everyone at the table glanced at each other, wondering what was wrong with Hilda while Oga just stared off in the direction she had gone. Eventually he got up and went to see if she was alright. Entering the bathroom, he was greeted with the sight of Hilda emptying the contents of her stomach into the toilet. Walking over to her, he helped her by holding back her hair and rubbing a circle into her back. When she finished he wet a face cloth and handed it to her so she could clean herself. When she finished cleaning herself she handed the face cloth back to him before falling back against his chest, feeling too weak to do anything.

"Are you able to walk?" He asked her. He felt her head move side to side against his chest. "Hey aneki, call Furuichi and ask for Lamia. Tell her Hilda's not feeling well."

"Alright" Misaki said. Oga then proceeded to pick Hilda up bridal style and carry her to their room. Once he entered he laid her down on the bed and sat down beside it. Hilda had curled into a ball once she was on the bed. Misaki came in a few minutes later to tell him that Lamia was on her way and that she would be looking after Beel.

Fifteen minutes later he heard a knock at his door. Turning around he saw Lamia and Furuichi enter through the door.

"What happened?" Lamia asked, as she noticed Hilda lying down on the bed.

"I don't know." Oga started, scratching the back of his head. "One moment we're all eating breakfast, the next she's spewing her guts out in the toilet."

"Well I guess I'll just have to run some test's to find out." Lamia stated moving closer to Hilda.

"I don't think that will be necessary." Oga's mother said from the doorway. Everyone turned to look at her confuzed. " Hilda, when was the last time you had your period?"

"Mom?! What does that have to do with what's wrong with her?" Oga cried in disbelief.

"About two months ago. Why do you ask?" Hilda said quietly. Everyone turned to see that she was now sitting up, with her hand on her chin. She wondering why Oga's mother would ask her such a question. As she kept thinking it over, it suddenly hit her. Her eyes widened and she moved her hand to cover her mouth. It couldn't be that could it. But as she kept thinking over it, all the answers pointed to that one reason. "I'm pregnant..." she whispered. She turned her gaze to Oga and noticed he was staring at her with wide eyes.

Oga couldn't believe what he just heard as the words Hilda just whispered bounced around inside his head. The first thought that came to mind was how could this have happened, but he quickly pushed it aside since he already knew the answer to it. But as he kept thinking about it, he started to get nervous and the more he thought about it the more nervous he got.

Lamia and Furuichi had also heard what Hilda said and were surprised by it as well. Well Furuichi was more in disbelief that Hilda and Oga had gone that far. (not to mention he was also jealous that Oga had lost his virginity before him, and to Hilda of all people)

Hilda was still in shock about it, but it started to wear off the more she went over it in her mind. Then a thought struck her. She was pregnant with his, no... their child. She turned to look at Oga again and blushed a bit. She felt odd when she thought of it like that. The fact that it was their child made it feel... special.

After everyone got over their shock, Lamia ran some test and confirmed what Hilda and Oga's mother had guessed earlier. Lamia and Furuichi left after they were certain that Hilda was going to be okay. Oga's mother went to the kitchen to prepare lunch, leaving the couple alone together in the room.

Hilda lay back on the bed, still dizzy and a bit tired from being sick. Turning her head she looked over to Oga and noticed that something seemed to be bothering him. Reaching over, she grabbed his hand with hers and intertwined their fingers, giving it a squeeze as well.

Oga looked at Hilda after he felt her intertwine their fingers. She was looking at him with a smile on his face. He felt his feeling of uneasiness fade a bit as he smiled back in return. Seeing his smile she slowly closed her eyes and fell asleep. Oga leaned forward and kissed her forehead before heading downstairs. He needed to go for a walk to clear his head.

"Tell Hilda I went for a walk if she wakes up before I come back." Oga ask his mother as he picked up Baby Beel and placed him on his shoulder before heading out the door.

Oga was standing by the river as he played what happened this morning through his mind. The uneasy feeling had remained the entire time and he couldn't seem to shake it. He cleared his mind and took a second look at the situation they were in. Hilda was pregnant. To be more specific, she was pregnant with their child. That thought alone made the uneasy feeling worse, but he couldn't figure out why. Sure he was Beel's father, and that had thought had scared him once before too, but he got used to the idea and eventually he started to like it. But this time it felt totally different and it bugged him since he couldn't figure out why. That's when it dawned on him.

This child was going his responsibility. Sure he was responsible for Beel, but there was always that chance that he could have chosen someone else as his parent, but this time there was no mistaking that he was the father indefinitely and it scared him. It scared him because no matter how he looked at it, this child would look up to him and he was afraid he was going to screw up, afraid that he wasn't going to be a good enough father.

He looked over to Beel, who was sleeping peacefully on his shoulder. A smile crept its way onto his lips. It was funny how almost a year ago he had tried almost everything to get rid of him. Now though, he would go to any lengths just to make sure he was safe. A thought slowly made its way into his mind and he soon became angry with himself. Why was he worrying over something so stupid. Beel was the perfect example of how good of a father he was, albeit not at first but he got better as time went on.

With that all cleared he start to walk aimlessly through town, still feeling like he was missing somethin. Like he had to do something else as well but he just didn't know what it was just yet. He abruptly stopped when he spotted something out of the corner of his eye. As he stared at the object, it dawned on him just what he had to do. Grabbing his phone out of his pocket, he dialed his sister number. After a few rings she picked up.

"Hey aneki, I need you to do a favor for me?" Oga asked.

"Sure. What is it?" Misaki responded over the phone. Oga then proceeded to tell her what he needed of her and where she was to meet him. He then hung up the phone and headed into the store with a big grin on his face.

Hilda woke up feeling slightly better than before. Her headache was almost gone and she didn't feel nauseous anymore. As her eyes fluttered open she noticed she was the only one in the room. Moving to sit on the edge of the bed she started think back to what had happened this morning. She was pregnant. She was happy about it but at the same time a bit nervous as well, having never thought of being the mother of her own child, but unlike Oga though, she knew she would be a great parent.

Pushing that aside she got up and headed down to the kitchen, to try to at least get some food into her system. As she left the room though she noticed that Oga wasn't in the house. She furrowed her brow as she wondered where he could have gone. Entering the kitchen she was greeted by Mrs. Oga, who had just finished boiling some water for tea.

"Hilda honey, how are you feeling" Mrs. Oga asked after taking the kettle off of the stove.

"Better, but I'm a little hungry." she answered.

"Well that's good. I'll go make you something to eat." Mrs. Oga said as she went back to the counter to make her somthing. She came back a few minutes later with dry toast.

"Do you know where Tatsumi went?" Hilda asked after she took a few bites out of her toast.

"He went for a walk, probably clear his head. Not everyday you learn that you're going to be a father." Mrs. Oga said. Hilda started to feel uneasy after hear this. What was bothering Tatsumi so much that he needed to go for a walk? she thought.

"Don't worry though. I know my boy, he'll come to his own terms on whatever is bothering him." Mrs. Oga assured Hilda, after noticing how troubled she looked. Hilda smiled, knowing she was just trying to make her feel better, but the uneasy feeling never went away.

About an hour later Hilda heard the door open. Knowing it was Oga she quickly walked over to the entrance way to see Oga taking off his shoes. She stood at the threshold with her hands on her hip as she stared at him with a small frown on her lips. When Oga stood up to look at her, she noticed that he had the big smile on his face, the biggest she had ever seen him have. He almost sprinted towards her and before she knew it he had pulled her into a hug. She was surprised, but returned the embrace anyways.

"I have a surprise for you later tonight." Oga whispered into her ear. A smile crept its way onto her lips and a feeling of anticipation slowly washed over her as she tried to picture what the surprise could be.

The rest of the day went by smoothly. After supper they put Beel to sleep for the night after which Oga suggested they go for a walk. Hilda agreed and went to get dressed in her regular black dress, though she didn't put on the gloves.

They walked hand in hand through the quiet streets, content with the comfortable silences between them before they stopped by the river. The sun was beginning to set as it cast a warm glow to the area. Both Oga and Hilda were staring at the river as the current calmly washed downstream. Hilda had her back resting against Oga's chest and his head was resting on her shoulder. He had his hands snaked around her waist, with one of his hands resting over top of her abdomen. One of her hands had grabbed the hand on her abdomen, squeezing it now and then.

"Where did you go today?" Hilda asked, breaking the silence. She turned her head to look at him.

"I needed to clear my head so I went for a walk." He responded, keeping his gaze pointed forward.

"Why?" She asked, turning her head to look at the river again.

" I just kinda got... scared..." He said meekly.

"Scared?" Hilda asked in disbelief, turning back and raising an eyebrow at him.

"Yes scared. Scared that I wasn't going to be a good enough parent for our child." Oga said. Hilda widened her eyes in surprise. Untangling herself from their embrace she cupped his cheeks in her hands and narrowed her eyes at him.

"You fool. Haven't I already told you. You are a great parent to Beelze and I have no doubt that you will be a great parent for this child. I know you will." Hilda paused. Oga was staring back at her wide eyed as she continued. "Now I don't want to hear you talk like that again. Is that understood." Hilda chided. Oga nodded his head in response as a smirk formed on his lips. "Good" Hilda said, turning to look at the sunset after letting go of his face.

"Thanks for believing in me." Oga said after a while had passed.

"Don't thank me." Hilda stated before turning her head to look at him again. "It's my job, after all." She said giving him a smile. "Now... didn't you say you had a surprise for me?" Hilda asked, looking at him expectantly.

"About that." Oga started as he scratched the back of his head. "This whole thing got me thinking, I know we got a lot of life ahead of us but I felt that it was time that I finally did this." Oga stated. Hilda watch him, wondering what exactly he was about to do. "Well what I'm saying is." He paused for a second, fishing his hand into his pocket.

"Hildegarde" He got down on one knee and presented a small black velvet box to her. Hilda's breath hitched, anticipating what was to come next.

"Will you marry me?" He asked, opening the box. Inside was a 14 karat gold diamond ring. The diamond wasn't very big in size but was surrounded by little emeralds. Hilda was speechless, never having thought she'd ever see Oga propose to her. She felt something warm start to trickle down her cheek and it wasn't long before she realized she was crying. She wiped away the tears and said the only word that came to her mind.

"Yes." Hilda said with the biggest smile on her face. Oga then got onto his feet before he took her left hand and slipped the ring onto her finger. It fit perfectly Hilda noted as she lifted her hand up to inspect the ring more closely. She noticed that along the band there were words engraved into it that read 'Tatsumi and Hildegarde forever'.

"It's beautiful" She said as she wrapped her arms around his neck and pulled him close to kiss him fully on the lips. Oga wrapped his arms around her waist and pulled her close as they shared a passionate kiss together. They parted a few minutes later, though they never let each other go, only holding on even tighter.

As the sun finally set and the first few stars of the night made their appearance, they started on their journey home. Hand in hand they walked along the path, both thinking about how much their lives had changed in the couple months that had passed. As they walked into the night they both knew of the challenges lay ahead for them the more they grew as a family, though there was one thought that they both agreed upon and that was they wouldn't want it any other way.
