Travel Of New God Through Dimension {High School DxD Arc}}

The day has passed, there was nothing interesting happening for Tendou Kamiya. It's just like normal daily life alongside his new family which consists of himself, Mio, RyuZU, AnchoR, Ellie, and Tiamat. The activities he does pretty much watching some TV drama and Anime with the others. He also read some manga, and play the game he ordered online when he doesn't have anything to watch. There is some similarity with what exists from his world with some alteration and some of them are completely new which he never knows, so it won't be too boring for him.

The next morning, Kamiya walking towards the school. In the middle of his walk, he meets Issei who was accompanied by Asia.

" Good morning Asia, Issei!" Kamiya increases his walking speed toward their location. then, he tapped Issei's shoulder and greeted both of them.

" Good morning Kamiya-san." Asia surprised by my arrival and politely greeting back.

" Yo, good morning." Ise replied with a tired expression.

" What happened to this guy Asia? you should know since you guys now living in the same house?" Kamiya asked Asia who walking alongside him.

" I also don't know. He doesn't look hurt and he doesn't have morning training with Rias onee-sama." Asia replied with a worried look.

" Don't worry about it, Asia. I already understand the situation, there no problem with him just need some rest. Though it's better if you don't know about it." Kamiya with understanding knows what Ise do when he was alone in his own room and calming Asia, so she doesn't look deeper into it. They keep talking with each other until something happens in the school corridor.

"Iseeeee!!" One of Issei's friend Matsuda running toward their direction with an extremely pissed face from the end of the corridor.

" Dieeeeee!!" From another direction, another Issei friends Motohama also running to their direction. Both of them preparing to use some sort of lariats move on Issei. Issei who realizes what they are planning doesn't have anywhere to run since we are in the corridor. He accepting his fate and gets double lariats by his friend, who were crying while protesting about the group Issei introduce to them yesterday. It seems there is a group of Mil-tan, macho strong guys from martial arts manga and wearing gothic lolita clothes.

"They were going on about the world of magic! Whaaaaaat the f.u.c.k is the 'World of Magic Serabenia'!? I don't know any shit like thaaaaaaat!" Matsuda continues to complain to Ise while shaking his body violently.

"In my case, they were telling me about how to defeat the 'Dark Creatures' if I ever encounter one... Apparently, you can kill them by using a special item which is made by mixing the salt from the sea of the dead and a flower that only appears at night called 'Moonlight flower' and then burn them to make powder... No matter how you think about it, a punch from Mil-tan would be enough to kill any living thing in this world..." Motohama says it while holding his head down.

"Congratulations. Now you can beat the 'Dark creatures' whenever you encounter one." Issei giving them an understanding look and calming them down. which resulting in them attack him once again.

" Hey, Issei do you think I should include Mil-tan friend into that secret Project? After all, when I think about it. It's looking very interesting when the opponent saw a macho man become cute magical girls. It's also can become a new Mahou shoujo serial." I telling Issei what I think after hearing their talk.

" Somehow I don't want to think about it..." Issei giving off resigned look and doesn't want to think what Kamiya just says to him.

---------------------------------------------------Lines---------------------------------------------------

After the class finished, Issei and Asia invited me to ORC, which I accepted. On the way toward the clubroom located in the old school building, we meet with Kiba who also went to ORC. The topic of conversation went into Rias in some sort of her household problem. When the group near the ORC building Kamiya senses a new presence He doesn't recognize inside the building. Issei opened the door into the clubroom without any concern.

Inside the room are Rias, Akeno, Koneko, and the new presence Kamiya just sensed a silver-haired maid. The maid looks in her early twenties with back-length silver hair that features a long braid on each side with small blue bows at the ends, while the rest is let down which ends in twin braids and red eyes.

" It seems Ojou-sama finally decides to bring her maid into school, though wearing school uniform doesn't seem a problem if you want a maid in all the time. Her power level also far stronger than your whole peerage combined power level." Kamiya said to Rias while showing a smirking look on his face.

" I'm a maid that serves the House of Gremory. My name is Grayfia, Queen that server under Rias brother Sirzech Lucifer." The silver-haired maid introduced herself.

" It doesn't like what it looks like, she comes for the family business. Also, this human is the one I mentioned in the report. His name is Tendou Kamiya." Rias explaining the situation and introduce me to her maid.

" Is that so... I have nothing to do at the moment and got invited here by Issei and Asia. By any chance, I intrude on something? I don't mind leaving though." Kamiya who sees the situation in the room decides to leave.

" There no need for you to leave, I don't mind include you with something I need to tell my peerage." Rias says to Kamiya and her peerage. Kamiya who hears that decides to not leave the room.

"Ojou-sama, do you want me to explain the situation?" Grayfia who offers her assistance got rejected by Rias who waving her hand.

" The truth is-" When Rias was about to explain her situation. The magic circle on the floor started to glow. The pattern symbol who appear was different from Gremory or Sitri, which means the guest was not from the Gremory or Sitri household.

" Phenex..." Kiba said when he saw the symbol on the magic circle.

From the magic circle, a flame started to burn. From the flame appeared a young man in his early 20's with short blond hair and dark blue eyes. His outfit consists of a burgundy blazer with gold embroidery on the right with matching pants and black dress shoes. Underneath his open blazer is a white dress shirt that is not fully buttoned, giving a slight view to his c.h.e.s.t.

" Fuu, it's been a while since I came to the human's world. My lovely Rias. I came to see you." The Phenex guy looks around the room and smirks when saw Rias.

"Now then, Rias. Let's go and take a look at the ceremony hall. The date of the ceremony is decided so we need to check it before then." The Phenex guy closer to Rias and grab her arms.

Within this kinda spectacle Kamiya moved to the corner of the room creating a chair to sit in and some snacks while watching the unfolding drama. No one in the room notice Kamiya's action, except for one person the maid Grayfia. It seems others the awareness level is just very low or too focused on the man's action to Rias.

"...Let go of me, Raiser!" Rias says that with a deep and serious voice while shaking the guy's handoff. Riser doesn't seem to care about having his hand shook off and just smirking.

" Who the heck is this guy? to do something like that to Buchou!" Issei said that with a displeased voice.

"...Oh? Rias, you haven't mentioned me to your servants? I mean, are there guys who don't know me? A reincarnated Devil? Even so." Riser seems surprised with Issei question

"I didn't tell them because there was no need." Rias said with a displeased voice.

"Oh my, harsh like always. Hahaha..." Riser who heard Rias replied start laughing.

"This person is Raiser Phoenix-sama. He's a pure-blood High-class Devil, and the third son of the House of Phoenix. He's also the fiance of the Gremory family Heiress apparent. That is to say, he's engaged to Lady Rias." Grayfia comes into the discussion and introduces Riser to others.

"Eeeeeeeeeeeeh!!" Issei screamed from revelation Grayfia make.

---------------------------------------------------Lines---------------------------------------------------

"The tea made by Rias's 'Queen' is superb." Riser praises tea brewed by Akeno.

"Thank you very much." Akeno replied with a smile, but without his usual 'Ara ara' and 'Ufufu'.

Riser sat next to Rias who was sitting on the sofa and holding her shoulder. Rias keep on shaking his hand off, but Riser keeps on touching her hair, hand, and shoulders. Rias servants are sitting way from both of them and only look at them.

" Cut it out already!" Rias angry voice echoes through the room. She got up from the sofa and is glaring sharply at Riser. On the other hand, Riser is smirking as usual.

"Riser! I told you before! I will not marry you!" Rias continued talking with an angry expression on her face.

"Yeah, I heard that before. But Rias, that won't do, you know? I think the situation of your household is quite serious." Riser says while drinking tea served by Akeno.

"That's none of your concern! If I'm the next heiress for the House of Gremory, then I will choose who will become my husband! My father, brother, and everyone in the clan is rushing it! Also, it was a promise that I will be free until I graduate from the University of the human world!" Rias started throwing tantrum.

"That's right. You will basically be free. You can go to college and you can do whatever you like with your servants. But your Otou-sama and Sirzechs-sama are worried. They are afraid that your household will become extinct. We lost a great number of pure-blood Devils in the last war. Even if the war has ended, our rivalry with the Fallen Angels and God hasn't ended yet. It's not rare for the successors of pure-blood Devil to get killed in the worthless battle against them, which leads to the household becoming extinct. So for a pure-blood Devil that is also happening to be a High-class Devil, getting together would be the obvious solution for the forces of Devils. A pure-blood High-class Devil. Even you know that these children will be important from now on, right?" Riser started arguing with Rias about the devil's side.

"The newly produced Devils—. The ones like your servants, the reincarnated Devils, are expanding in terms of strength but that would make us, the High-class Devils with old historical backgrounds, lose our place. There are old nobles who gets close to the reincarnated Devils because they are very powerful. Well, that might be alright. The newly produced Devils are also important for our future. But we can't allow the pure-blood Devils to go extinct right? You and I were chosen in order to prevent the pure-bloods from going extinct. My house is safe because I have my older brothers. But there are only two siblings in your house. And your brother is someone who left the house. Then there would only be you, Rias, who can inherit the House of Gremory. If you don't take a husband, the House of Gremory will go extinct in your generation. Are you trying to crush the household that has been continuing for a very long time? Because of the past war, there is not even half the number of Devils who were referred to as '72 pillars'. This marriage has the future of the Devils on the line." Riser continues to give the reason why his marriage with Rias kind of important.

Kamiya who heard Riser's explanation about pure-bloods going extinct started to think about Gremory's house pretty much in the brink of removed from '72 pillars'. Since the abilities, Kamiya's sense from Rias so far doesn't show any trait of Demon who represents Gremory in Ars Goetia. The power of Gremory should have is Prophecy, the power to see the future, and choose the best scenario from the provided future. Instead, Rias only showing the power of destruction which should only belong to Bael clan. 'It seems the head of the Gremory clan is afraid of losing the status as '72 pillar' or the one who behind the scene pushing this event.' Kamiya who thinks about it just keeps silent and watching the situation in front of him unfolding.
