High School DxD Ex: Supernatural Realism

Chapter 1 – The Scarlet Son and the Introverted Daughter

Ex's POV:

My name is Ex Gremory, I'm 14 and I'm in 8th grade. I study in Kuoh Academy where many extraordinary things happened. Unknown to the normal humans' knowledge, devils, fallen angels, and angels are also studying there and we belong to all of those kinds. I harboured deep hatred towards my father, Issei Hyoudou Gremory 'cause he's always out for missions for almost 20 years I think and he always make my closest sister, Airi, upset. Airi and I live in a Harem where my father has many wives and children, including us. Based from Azazel, he knew us before we were born in this world and Airi was being the second of the eldest. He was in great shocked that time that I was 10 months older than her. Guess the future changed. Anyways, the eldest among us is the one and only Kurenai Himejima who is 17 and now in senior high school. He is fond of researching different things and he is acting like Azazel. By the way, he's aunt Akeno's son. The second one is Ernestine Karnstein, also 17 and the daughter of our vampiric mother, Elmenhilde Karnstein. She's very serious in so many things. She was trained by uncle Gasper but I don't like her. The third child is our brat brother, Mordred Hyoudou who is also angry with dad. His age is 16 and the son of Le Fay Hyoudou. I admit that he's a magic expert but he is more annoying than Ernestine and Kurenai! The fourth is Helmwige, the daughter of Rossweise whose age is also 16. She has a bad habit of cutting classes because of her magic training and let my sister Airi do her homeworks. The fifth is Zen Quarta, son of Xenovia Quarta and my most stubborn sibling. He is 15 and always gets along with Shin and Airi. The next is Shin Shidou, the son of Irina Shidou who has mysterious wings but he stays joyful like his mother. He also gets along with Airi and Zen as they are known as the New Church Trio. You probably know me, as the seventh and son of Rias Gremory so I will introduce Airi. Airi Hyoudou is the daughter of Asia Hyoudou. She is also 14 but like I say, I'm 10 months older than her. There is something different from her. Based from Azazel, she was very energetic and brave in the alternate future but here, she is an introvert. She avoid in so many contact with people, also with our other siblings. She only talks to me, Robertina and our friend, Claud Kiba. She is very kind and accepts everyone. I'm very worried about her because she's been tortured mentally in our school for she's smart in almost everything, except in Mathematics because she has a hard time dealing with it. She always cries in our room but she always kept smiling. She is my roommate so I always know what's going on with her. The next one is Robertina Hyoudou, the daughter of Ravel Hyoudou whose age is 13. She is less serious than Ernestine and also a part of a cheer club in our school. Shirayuki, daughter of Koneko, and Kurobara, daughter of Kuroka, are both age 12 and they are nekomata sisters at the same time, cousins.

Airi's POV

Azazel said to me earlier that my alternate self was very different from me. He said that my alternate self was energetic, scary, and brave. Whoah! I just can't really believe that my alternate self was like that. I wish I could but I can't, I just have a low self esteem. I came out of our door and saw Ex, my older brother, holding a small trombone that sounds really loud. Oh no, he's going to prank Kurenai again. Before he'll blow in it, I tried my best to run to him and jump over him, "EX NO!" I shouted as we fell flat on the floor. I grabbed the trombone immediately and threw it somewhere, "Airi?! Hi…" he greeted as he let out a nervous smile. "How many times do I have to tell you that you have to limit when it comes to prank right?" I scolded at him as we walked through the hallways, "Yeah but he's really annoying you know. He's acting like Azazel!" I laugh a bit about what he said, "Want to race down?" I realized that we are near the staircase. Ex always let himself slide down the handle of the staircase, "No thank you, Ex! I'll take some steps," I said for I fell down while sliding on the handle when I was an eight year-old. I know it's pretty silly but it's true. Ex let himself slide down to the handle of the staircase while I only step down. As I reached the last step, Ex is already at the kitchen, probably talking to mom about breakfast. I smiled to myself and go inside the kitchen. There, I saw Ex and our younger sister, Robertina or should I say Tina because that's her nickname, "Morning, Airi!" my mother, Asia, greeted me with a benevolent smile, "Morning, too, mom!" I greeted back. "I saw that you stopped Ex again from annoying Kurenai," Tina said, "You know, Tina, just don't imitate our brother's attitude when it comes to joking for it makes non-sense fights. Right, Ex?" Airi said as Ex put himself behind Asia's back, "You're afraid at Airi even though you are older than her?" mom asked him, "Auntie Asia, Airi is very scary, you know! She always stop me from my plans to prank Kurenai," Ex said, "Aww…so my big old brother is afraid to my very kind sister," Tina teased as both of them heavily teased each other. I kinda smile at them, seeing my siblings enjoy their time together makes my heart shine for they are happy, "Alright you three, you must eat your breakfast or you'll be late for school," said mom and all of us eat our breakfast which is our favourite, her special pancakes with berries on top. When we finished our breakfast, we all bid goodbyes to her and go out to our home. Tina separated from us for she has a group of friends waiting for her. Ex and I always go to school together, hang-out together and study together. He is like my protector and we also have two other friends. Their names are Draco Vladi, our nerdy best friend and loves mathematics. Unknown to others, he is a dhampir, a half vampire and half human creature. And the last one is Claud Kiba, my childhood best friend and also my playmate. As we grow older, we grow distant but still, we are friends, but not as close as before. He was a half devil and a member of fencing club. I developed romantic feelings for him but he doesn't know about it though.

Ex's POV

"Took you so long, Hyoudou Siblings!" said Draco as he approached towards us. He usually wears his eyeglasses and wearing his blazer with a bow tie?! Yeah, it's a bow tie that was clipped on his collar, "What's up, nerd dude!" I said chuckling as I pat him heavily on his shoulder and he easily gives me a punch on my shoulder, "That's what I called payback!" Draco exclaimed and we both laughing at each other, "Okay! So can we go inside the school now? We're getting late, you know" Airi said as she crossed her arms, "Alright! C'mon smarty pants!" The three of us entered the school. The bell rings everywhere and it sounds really annoying. I really hate studying and I love spending my time playing video games, eating chips, and reading comic books. Well, I'm not like Airi who spends her time reading and studying all day at the backyard or in our room, "I'm going now! Bye Ex! Bye Draco!" Airi bid, "So is it true that Airi is being bullied by her classmates? I mean she's smart. But don't you see that your sister is an introvert?" said Draco, "I know that. I care deeply for her because she's also my best friend not just a sister," I said, "Well, you better watch her, dude for there are lots of bullies here who could hurt her by words or even physically," Draco said. I'm sure that I want to protect my sister, I'm not saying she's weak but she's too kind to accept everyone, like mommy Asia, "Ex, you alright?" Draco asked and I snapped out from my thoughts, "Umm...yeah! Of course I'm alright!" I reassured. As always, I never listen to my teacher's leisure. I'm just sitting in the corner, looking outside as the sun shines brightly, "Can you answer my question, Mr. Gremory?" I looked at my side and WAAAHHH! It's our teacher! I forgot that our subject is Science and I'm not really good at it! What am I going to do now? Oh! I could just let myself jump out of the window and 'voila! but the teacher will call either Airi or Kurenai! Damn! I'm really dead! "Can you repeat the question please?" I asked nervously, "Alright! What is the constellation with the shape of a swan?" she asked, "that's an easy question, Mr. Gremory. I believe you had listened to my leisure," she said. Oh no! This is simple because we tackled this in our primary levels! Yes, thanks to video games and I forgot our past lessons! "Aquarius?" I answered, "WRONG! YOU ARE NOT LISTENING AGAIN!" she shouted and I automatically went outside. ************************************************************************************************************************************

"You got kicked out from your classroom because you didn't answer your teacher's simple question?!" Airi exclaimed as we walked home. 4 hours had passed and school's over, "so what's the question?" Airi asked, "Well, what is the constellation with the shape of a swan and I answered Aquarius," I said. Airi gives me a shocking look and slapped me on my shoulder, "You nuts! The answer is Cygnus! Hehehehe," she laughed. I can see that she showed a great smile but, behind her smile is a sad moment. I noticed that her face is red like she got slapped?! "What happened to your face?" "Oh! This is nothing!" she said, "You've been bullied again? Why you didn't tell me? Look, as you older brother, I want to protect you!" I said, "Ex, I know but I don't want you in my troubles and I'm alright! You see," "Those smiles have hidden meaning. Who did that?" I asked, "Amy and Gretchen. They always hurt me by words but for today they slapped me," she replied, "please don't tell this to mom, and also to dad if...he ever comes home," she said, "He'll never. Why do they hate you?" "Because they said that I'm an introvert and introverts do not belong in this world!" she said tearfully. I held her hand and said, "Don't worry, I swear that I'll kick their butts if they do that again," I said and she smiled. "Azazel said that in alternate future, I was older than you," she said, "Well, I'm older than you!" And we go home.
