Beta read by jneth1lary88.

Recap:

Hilda was on her left side, facing Oga who was on his right. She snuggled her head under his chin as he brought a sheet up to cover them, then wrapped his arm around her waist to bring her close. They both quickly drifted off to sleep in each other's arms, with a new feeling of confidence that they were going to get through this.

So The Battle Begins

Hilda woke up feeling different. She couldn't really explain it, it just felt like she had a lot more energy. Opening her eyes she found herself on her side, naked and snuggled into Oga's chest with her head under his chin. Oga had his arms around waist and she, in turn, had her arms around his back. Her lips curled into a smile and she cuddled closer to him. She started to remember the events that had happened the night before and she blushed, though her smile never left her face.

Some time went by before she felt it was time to get up. Moving out of his grip and into a sitting position, she stretched out her arms and yawned. Oga awoke when he felt her move and looked over to see what she was doing. He was somewhat shocked to find her completely naked beside him, but it quickly wore away when he too remembered what happened the night before. He turned onto his back and kept his gaze fixed on her. She looked beautiful and he couldn't stop starring. He wondered why he never noticed it before. Before he knew it, he had snaked an arm around her waist again and pulled her towards him. Hilda felt his arm tugging her by the waist towards him. She turned her body so that she landed on top of his chest with her face was hovering over his face.

"Morning Tatsumi." She said and leaned in to give him a peck on the lips.

"Morning." Oga said after the kiss. Hilda rested her forehead against his as they stared into each others eyes. After a while they both got up out of the bed and got dressed. Heading down stares to have some breakfast, they both noticed that the rest of the family seemed to be giving them an almost knowing look, but they chose to ignore them.

"So will we be seeing a new nephew or niece anytime soon." Misaki asked. Both Hilda and Oga immediately blushed and tried not to choke on their food. "I hope you have a daughter. With Hilda's genes she'd look so cute!" Misaki gushed.

Both parents were speechless. Trying to avoid the access attention they finished their breakfast as fast as they could and bolted upstairs to get ready for the day before anymore embarrassing questions could be asked.

When Oga and Hilda arrived at Furuichi's house, Lamia noticed something was different about the couple. It seem almost as if there was a different air about them, but she couldn't quite figure out what it was that was different. Deciding to take a closer look she noticed a black mark on both Oga and Hilda's left hand. Her eyes widened a little. They made a contract together? She thought. She wanted to question them about it, but decided against it, as their were more important matters to attend to.

"So, what exactly did you guys find out?" Furuichi asked. Oga had called earlier saying that had some information on the whereabouts of Baby Beel.

"We believe this is where they might be holding him, but we're not entirely sure." Hilda said, handing the card over to Furuichi.

"Hey, this address is in the human world." Furuichi stated after examining the card.

"We already know that."

"Then why haven't you guys already gone to get him?" Furuichi asked out of curiosity.

"Because that might be what they want them to do." Lamia spoke up. "The thing is though, they think it will be easy since Oga doesn't have a contract with a demon any more."

"But he actually doesn't anymore, right Lamia?" Furuichi asked. "Lamia?"

" Its true. He doesn't have a contract. It's something more than that." Lamia stated.

"What are you talking about, Lamia?" Hilda asked.

"Well, actually you both have made a contract with each other." Lamia said. Bewildered by what Lamia said, both Oga and Hilda brought their hand up to inspect it and sure enough they both had a mark there. On Oga's hand there was a small, black rose. It had a shot stem that spit in two, circling the rose and intertwining with each other above the flower. On Hilda's hand was the name Oga in kanji. It was circled by what looked like the stem of a rose. They both stared at them in awe, but Hilda seemed the most taken aback by it.

"They made a contract together?" Furuichi asked with a little bit of envy.

"Not just any contract, this is a life mate contract." Lamia said a little too excitedly. Furuichi gave her a confused look so she continued. "Its a special contract where the souls of the two making the contract intertwine. It's a permanent contract which can only be broken by death." Lamia was silent for a while as she let the information sink in before she continued. "And since Oga is human it has a different affect on him. He now has the life span of a demon, but if Hilda is to die, he will as well."

Hilda was shocked beyond words, not by Lamia's explanation, but by the fact that she made a life mate contract with Tatsumi. She was happy beyond words as she had made the most special of contracts with the only man in the word that she would ever consider being in a contract with. But as the thought kept running through her head, she started to feel guilty. She felt guilty because while Beel was in trouble, she was happy because of her contract with Tatsumi. Not to mention she felt like she was taking advantage of Beel by being in a contract with Tatsumi while he wasn't there.

Oga was shocked as well when he saw the symbol on his hand. But what shocked him more was that this contract lasted a lifetime. Though when he started to think about it it made him happy to know that he would be spending the rest of his life with Hilda. He looked over to Hilda and noticed that it looked like something seemed to be bothering her. He took a glance at Lamia and gestured towards the door. Lamia caught the signal and left the room, taking Furuichi with her.

"Is everything alright?" Oga asked. These kind of situations were awkward for him, but he didn't like seeing Hilda so down trodden.

"Is it alright that we made a contract together while Beel-sama isn't here?" Hilda asked, turning to him. She locked eyes with him and he could see the guilt in them.

"Is that what's bothering you?" Oga asked out of curiosity.

"I just feel like I'm taking advantage of him since I made a contract with you while he's not here." Hilda said, staring down at the ground. The guilt only seemed to get worse, the more she thought about it.

Oga chuckled a bit. "Woman, Beel would be ecstatic if he found out we had a contract together." Oga said, placing a hand on her shoulder. He couldn't help but smile as he started to remember some of the moments when they acted somewhat like a family and how happy Beel was in those moments. " You know how he gets when we actually act like a family together."

A smile formed on her face as she remembered all the those times as well. The guilt she was feeling diminished instantly and was replaced with the familiar warm feeling. "Yeah, I guess you're right." She said. She closed the distance between them and wrapped her arms around him, pulling him into a hug. Oga wrapped his arms around her and hugged her back. They both stayed like that for a while unaware that Lamia and Furuichi had been watching them threw the crack in the door.

"Out of all the years I've been friends with Oga, I've never seem him act like this." Furuichi stated, pulling away from the door.

"Ya I know. I've never seen Hilda nee-sama act like this before either." Lamia replied, watching the couple.

"Is it really ok for Oga to have a contract with Hilda?" Furuichi asked, sounding somewhat worried.

"I wouldn't worry too much about that. From what I've witnessed, he should be strong enough to handle two demons." Lamia said. Turning to look at Furuichi.

" But didn't the demon lord personally cut the link between Oga and Beel?" Furuichi asked, scratching his chin as he tried to remember Oga's story from before.

"Actually that's not true, only the two that have formed the contract can actually break it. The Demon Lord was only able to temporarily cut the link." Lamia stated.

"So essentially Oga still has a contract with Baby Beel."

"Yes."

"And once the link is reestablished he will have the ability to use both Hilda and Beel's demonic powers." Furuichi asked.

" In theory, but we don't really know if he is able to use both of their powers at the same time. We never had a human with more than one demon under contract before." Lamia said , though her voice sounded uncertain.

Just then the door opened to reveal Oga. The expression on his face was one of seriousness. "Lets get to work. We got a rescue to plan."

"Are you sure he's here?" Furuichi asked Lamia. They were standing outside the gates to an abandoned building, along with Hilda and Oga.

"I'm positive. It's very faint, but he's in there." Lamia said. She looked over to Hilda and she could see she was looking towards the building as well.

"It's strange. I expect more demons to be here." Hilda said cooly. Her arms were crossed over her chest as she eyed the building suspiciously.

"Ya, I know, but this might just make things easier for us." Lamia stated, eyeing the building as well. She was about to continue when she saw Furuichi making his way over to them.

"So, everyone remember what they got to do?" Furuchi asked. He got a nod in response from everyone. He noticed Hilda making her way over to Oga, who was casually leaning against the wall, staring at the building as well.

"You ready?" Hilda asked. He nodded his head, his eyes never leaving the building. "Good, because I'm counting on you." She said, before moving closer to him. "One more thing." She was standing right in front of him, looking straight into his eyes. Oga turned his attention towards her, wondering what else she had to say. "Don't you dare die on me." She said a bit softer. Oga was taken aback by that before a smirk formed on his lips.

"I wouldn't even dream of it"

"Good." Hilda said as a smirk form on her lips as well before she leaned up and pecked him on the cheek. She turned and made her way towards Lamia before they both started for the side of the building. Oga's eyes never left her until she disappeared into the building. Once she disappeared, he made his way through the gates and toward the main entrance. Furuichi silently followed him as they made their way through the main entrance and into the large front lobby of the building.

"So you came after all... Contractor."

Both Oga and Furuichi turned to find a man in a white suit, standing at the top of an open staircase that was straight ahead of them. He had shoulder length blond hair with a few strands that ran in front of his face.

"Yeah, and..." Oga said nonchalantly.

"Hmph. Anyway, are you here to give yourself up or are you here to fight for your freedom?" The strange man asked with a smirk on his lips as he casually made his way down the stairs.

"Neither" Oga said while rolling up his sleeves. "I'm just here to kick your ass!" He shouted as he launched himself at the man. As he pulled his arm back to punch, the rose seal on his other arm started to glow and the stems almost seemed to grow up his arm. Black miasma started to collect around his fist as he hit his target, creating a small explosion. Once the dust settled, the man was standing about ten paces away without a single scratch on his being.

"Seem's you made a contract with the wet nurse, but it won't be enough." The man stated, dusting himself off.

"Yeah, but it will be enough to defeat you!" Oga shouted as he lunged at him once again.

Hilda and Lamia were making their way down a corridor on their way to find Baby Beel. They were met with very little resistance along the way, which Hilda easily dealt with. Reaching the end of the corridor, they entered a large room with a single door on the other side.

"He's just beyond that door!" Lamia shouted as she pointed towards the door.

They were running towards the door when they stopped just beyond the midpoint of the room when they heard someone laughing. Turning to the source, they both immediately recognized who it was. Athrun stood to the side of the room, leaning against the wall. He with his eyes closed, with his head facing the ground.

"So you came to retrieve the young Lord on your own. It won't matter, since this is as far as you will be going." Athrun stated. He walked toward the middle of the room across from where Hilda was standing. Unsheathing his sword, he got into a fighting stance. Hilda unsheathed her sword as well. They both stood still, keeping their eyes trained on the other, waiting for the other to make the first move. Athrun launched himself towards Hilda, slashing his sword across her chest. Hilda expertly dodged it and countered with a slash of her own that was aimed for his side, which he easily dodged as well.

"So the rumors are true. You are as tough as they say." Athrun said with a smirk.

"Well I wasn't an elite wet nurse for nothing." Hilda stated stoically. She readied herself again before launching at him, sending a barrage of strikes aimed a various parts of his body. Athrun dodge all but one strike that nicked his arm. The cut wasn't very deep, but it showed just how good the wet nurse in front of him really was.

This fight is going to be more of a challenge than I thought. Athrun thought to himself.

As Hilda waited for the next strike she couldn't help but notice how much more powerful she felt, no doubt do to the contract. It felt like she was fighting in the demon world and she was't even using her full strength. I just might have the advantage in this fight, but I can't be too reckless. She thought.

As they both readied themselves for another round, neither of them had noticed that Lamia was no longer watching the battle.
