Hello and welcome back to another chapter. Before we begin I would like to announce that the 2nd branch story is still in the brainstorming phase, so you have a lot of time to vote on what you would like to see in the next branch story. I would like to remind all my readers that updates for these stories are not consistent. I update them when I can which always changes weekly. I don't own anything related to Fairy Tail or Highschool DxD. Without much else to say, Let's get started.

Underworld

A few days had passed since the rather short spar between Natsu Dragneel, and Sirzechs. Once Natsu had woken up Sirzechs informed him that they would leave for home shortly. Gathering up his belongings, which wasn't much, Sirzechs opened up a portal to the underworld and walked through with Natsu trailing behind him. Stepping through the portal Natsu found that the sky seemed to be a faded green color in comparison to the bright blue he was used to. Other than the different color of the sky, the surrounding area didn't look to different from where they were before. "Natsu, come on now don't fall behind." Sirzechs called out before turning around and continued walking.

During the walk to the Gremory Manor, Sirzechs decided this as the best time to tell Natsu about his family like he promised. As he expected, Natsu was very eager to meet what would soon be his new family. 'That boy is full of energy, I can sense the purity of his heart. I hope he will be able to live up to expectations, or else we are all doomed.' Thought Sirzechs as he watched the young boy run around the area. Not even a full half hour later, the two arrived at the front gates to the Gremory Manor, soon-to-be Natsu's new home.

Going up to the nearest column, there was a panel with a button and a speaker. Pressing the button, Sirzechs spoke into the speaker. "Hello?" getting a response almost immediately a voice spoke up. "Oh, is that you master, I thought you were supposed to arrive yesterday." Chuckling in amusement, Sirzechs replied. "Indeed I was, but I ran into a special guest the other day, and I would like to bring him with me inside, is that alright?" Once again the voice responded immediately. "No sir, that's not a problem for me at all. One sec." Less than a minute later, the two outside heard the gate click open, before sliding horizontally out open the pathway that led to the front door.

Several minutes later

After a rather short and uneventful walk up the path leading to the door. Sirzechs turned to look at Natsu once more, before knocking on the door.

After a few minutes, the door opened up showing a rather busty silver-haired female all in a French maid outfit. "Welcome back Sirzechs-san, I take that this boy is our new guest?" she asked. Getting an affirmative from Sirzechs, she turned to Natsu before doing a short bow. "Why hello there, my name is Grayfia Lucifuge, and I am the Gremory's head maid. I serve as Sirzechs-san's Queen."

Natsu just took one look at her and gave her a small smile she found extremely cute. "Nice to meet you. My name is Natsu Dragneel." He said before running off to who knows where. Deciding to let his poor manners aside for now, Grayfia turned to remind Sirzechs that he still has some more paperwork to do. At the mention of the dreaded task before him, Sirzechs started to run out of the manor.

Before he could even step back out the front door, he felt something freeze his legs, tripping him. Turing around, he saw Grayfia standing right next to him. "Sirzechs-san this paperwork is highly important to maintaining the peace within the devil branches so you must get started right away." She said, and as soon as she was finished, she picked up Sirzechs by his still frozen legs and dragged him to his office, with him clawing at the ground trying to break free from the iron grip of his Queen.

With Natsu

After running off to who knows where, Natsu stopped and took a moment to take in his surroundings. Finding his way to a window that overlooked the backyard as well as the manor gardens, Natsu took a look out said window and saw he would say looked like a female version of Sirzechs if Sirzechs was around the same age as he is. (Natsu is 10yrs old right now) Curious, the young pinkette watched as the red-haired girl played in the gardens all by herself. Wanting to make another friend, Natsu made his way out to the gardens.

As it turns out, the entrance to the gardens was relatively close by. Entering the gardens, Natsu looked for the girl he saw earlier. Not seeing her anywhere, he started to walk around the gardens. About a half hour into the gardens, Natsu heard something. Quickly piecing it together that the noise he heard originated from the girl he saw in the gardens earlier, Natsu started running to the source.

Once he reached the source, Natsu came face to face with the same girl he saw earlier who happened to be humming a beautiful tune. In the girl's hands were some flowers from the garden. Soon the girl got up and turned around, coming face to face with the curious pinkette. Startled by his sudden appearance, the girl instantly panicked and fell down her butt. Walking up to her Natsu held out his hand to the girl. In response, the girl took the hand, and Natsu helped pull her up.

Once she was on her feet, she asked. "Who are you, and why are you here?" taking a few steps back, Natsu responded. "My name is Natsu Dragneel, I'm here because a red-haired man brought me here to join his family." Figuring out that the 'red-haired man' Natsu was referring to was her older brother, she introduced herself. "It's a pleasure to meet you, my name is Rias Gremory." They made some more small chat, and shortly started to play some games.

Sirzechs' Office

Watching the two children having fun together from a window in his office, made Sirzechs happy that they were getting along, while also slightly jealous of Natsu for spending time with Rias. You see, Sirzechs loves spending time with his little sister, so much so that some would claim to say that he is obsessed with how much time he spends with his sister. Much to his sister's chagrin.

As he was about to get up and go and spend some time with his little sister he felt a chilling aura right next to him. Slowly turning his head to look at the source, Sirzechs started sweating bullets. Said source was none other than his queen Grayfia, who at the moment was giving Sirzechs a stern glare. "Sirzechs-san, while I understand that you want to spend some time with your sister, you need to finish all your paperwork first." She said in a stern tone. One that demanded compliance or face punishment.

Masking his fear, Sirzechs recomposed himself before responding. "I'm already through most of it, I want to take a break right now." Before turning around and walking to the door. As soon as he reached for the doorknob, the entire door froze, leaving Sirzechs trapped in the room. Turning around to look at Grayfia, he was startled and more fearful than ever to see her right behind him with an icy aura emerging from her. Looking at him she spoke up. "Work now. Sister later."

Reluctantly Sirzechs complied, and moved to head back to his desk, only for him to burst out running for the window. Not even blinking an eye, Grayfia went and froze Sirzechs right up to his waist. Huffing in annoyance, Sirzechs dispelled it before turning to look at Grayfia. "Geez Grayfia you really need a boyfriend." He muttered. Grayfia however, heard the comment and completely froze Sirzechs before looking the other way and walked out of the room with a minor blush on her face.

And there you have it, another chapter done and ready to go. Sorry for the long wait but hey, it could be worth it. Not much else to say other than that Natsu won't have a harem until we reach the main storyline for DxD. Remember this is several years before the storyline of DxD starts. The members of his harem will start waving their colors early on, but it won't be until we reach the main storyline will the harem get underway. Not much else to say other than I will see you when I see you.
