Chapter 1

16 years later

(3rd pov)

We now come to a somewhat skinny 16-year-old, 5'6, fair-skinned, long dark blue-haired girl, with d cup breasts and an ass to match, covered with light blue flame-like tattoos on her body, laying under a tree, in a backyard, with her eyes closed seemingly sleeping, with a peaceful smile on her face. She was also wearing a white long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, a black shoulder cape and matching button-down corset, and a magenta skirt with white accents. If you look hard enough, you can see that she is wearing shorts underneath the skirt, though they are hard to see because of the skirt.

A shadow then came over her and she opened her eyes, revealing her blue eyes with black pupils, and looked up to see a 17-year-old high school student at the height of 5'7 with short spiky brown hair, with two short locks of hair behind his head, and light brown eyes.

He is wearing a black blazer with white accents over a white, long-sleeved, unbuttoned dress shirt with vertical linings, a red t-shirt underneath the dress shirt, black pants, and blue and white sneakers.

"Come on Ace, we got to get to school!" The boy said to our protagonist with excitement.

"The only reason you want to go to the school is to look at the girls there, Issei," Ace retorted rolling her eyes, making the boy, Issei put a hand over his chest and gasp with a fake look of hurt on his face.

"That is so not true Ace," Issei said in an overdramatic and fake hurt voice.

"Issei, I've known you and lived with you since you were about halfway through your first year of high school now, and I know that you are, without a doubt, the most perverted person I know," Ace said in a matter of fact tone.

This caused Issei to hang his head, with a small dark cloud pouring rain over his head, while he was also crying overdramatically.

Ace then got up, with Issei's help after he stopped being theatrical, patted her skirt, and went towards the house they both live in with Issei in tow.

The house is a normal two-story terrace house with a light blue exterior, a balcony on the second floor, and a brown roof.

Our two main characters were then greeted by Issei's mother and father, Gorou Hyoudou and Miki Hyoudou.

Gorou Hyoudou is an ordinary office worker. Gorou has the appearance of a middle-aged man with brown hair and brown eyes which his son inherited, as Issei is noted to resemble him. He also wears glasses.

Miki Hyoudou is Issei's mother and a full-time housewife. She has the appearance of a middle-aged woman with dark brown hair that is tied into a ponytail and hazel eyes.

By the way, Issei gets his pervertedness from BOTH of them, which means he was literally born a pervert. Though I don't tell anyone about that, which the family is grateful for.

"Hey auntie, hey uncle," Ace greeted the two. During her stay with Hyoudous, she was basically treated like she was part of the family, hence the auntie and uncle.

"Hi mom, hi dad," Issei also greeted his parents.

""Hi Ace, hi Issei,"" they both greeted the two at the same time in total sync, slightly unnerving everybody once they realized what happened.

"Never do that again," Ace said in a slightly creeped-out voice.

"Agreed," said both of the parents.

"Oh Ace look at your little uniform, it is so cute on you!!" Miki practically squealed, causing Ace to blush and pout while saying "I'm not cute", though she didn't notice.

"Hmm, she does look really cute in that outfit," Gorou said once he had a good look at what Ace was wearing.

"Thanks, though it does make me feel...girly," Ace admitted, not liking to look really girly, for several reasons.

"""THAT'S WHY IT LOOKS SO CUTE ON YOU!!!""" all the members of the Hyoudou family yelled at once, scaring Ace in the process making her jump and nearly fall. If Issei didn't catch her with one arm.

"Thanks, Issei," Ace thanked while getting up, while Issei acted like a big brother and helped her.

"Look at the time!" Miki gasped out loud, causing everyone to look at the nearby clock and gasp as well.

""We need to go, bye love you both," Issei and Ace both yelled out while running out the door to school.

They are both now in front of a giant school building, this place is Kuoh Academy and it was recently remade.

It was originally an all-girls private school, though at some point before the first school year, it changed into a co-ed school and the new school building was made.

"Is that Issei Hyoudou?"

"What is he doing here with a pretty girl like that?!"

"Is that his girlfriend or something?"

"Do you really think that he would be able to get a girlfriend?!"

Those are just some of the things that we heard when they both walked past the school gate.

Though to be honest, if he was anyone else I would've sided with them, but this guy is basically like a brother to me.

Ace was about to go walk in the direction of the voice who said it when a soft "stop" was heard and she stopped myself from doing so, while they were still walking towards the school.

""Issei! Ace!"" They both turned around and saw Issei's very perverted, but not nearly as him, friends Motohama and Matsuda.

Motohama has black hair that goes to the base of his neck and wears glasses.

Matsuda... has a human monkey face. He even has a shaved head.

Together these three make the Perverted Trio, the most infamous group in all of the school.

Ace only knows them because they are friends with Issei. They also tried to flirt with her, though that ended poorly with both of them buried in the ground heads first, by one well-placed punch.

"Ace!" We heard someone call her name, which she then turns around to see her best friend Aika Kiryuu.

Aika Kiryuu wears spectacles, has gold-colored eyes, and lightly messy brunette hair tied into braids on each side. She also wears the Kuoh Academy girls' school uniform.

"Aika!" Ace yells and hugs her best friend, which said girl grinds slightly on her crotch which caused Ace to push her away, blushing.

"Still a pervert I see," Ace sighs with her face in her hand, still blushing.

"And you still have a great size," Aika said, much to Ace's embarrassment, though Ace didn't know if she meant her breasts or her 'little' friend.

Ace just huffs and walks towards the school building, unknowingly swaying her hips slightly.

The Perverted Trio and Aika look in her direction, then looked at each other, all making a silent vow to protect Ace, though she had no idea about it, before following Ace inside, where we see her waiting for the others.

They all then walked to the student council room.

After Ace got her schedule from Sona, who was a joy to be around (not sarcasm, really), and the friends splitting up into their classes, we now see Ace walking up to a classroom.

She takes a deep breath, before knocking on the door. After a few moments, it opened revealing the teacher.

"Oh, you must be the new student we heard about," the teacher said, to which Ace nods.

"Wait one moment," the teacher said before closing the door, leaving Ace outside to wait.

After a moment, the door opened back up, to which Ace walks in, thanking the teacher, and walks in front of the class.

"Alright everyone, we have a new student," the teacher said while pointing to Ace.

The teacher was about to say more, but Ace beat her to it.

"Hello everyone, my name is Acnologia Mugen, but everyone calls me Ace Infinity because I like it," Ace said with a smile, revealing her full name and preferred name.

"Things I like: my mom, my friends, and the Hyoudou's," Ace said, which caused everyone to yell "WHAT?!" at her because she is friends with Issei.

"Things I hate: (most) perverts, arrogant people, bratty people, whiny people, Issei's pervertedness," Ace said, which caused everyone in the room to sigh in relief.

"That's it, so...any questions?" Ace asked, finishing her introduction.

"Do you have a boyfriend?"

"I'm not into boys," Ace revealed, causing everyone to gasp, groan, or sigh in relief. Ace just raises a brown to their behavior but doesn't say anything about it.

"Where do you live now?"

"Issei's place, and before you get mad, he isn't that bad a guy-" Ace started, though she stops as she notices that the last part went unheard as everyone was getting worked up about me living with Issei Hyoudou of all people.

Ace just sighs then looks at the teacher, who gets the students to calm down.

"Alright Ms. Infinity, your seat will be right next to Koneko," the teacher said while pointing over to Koneko, who is in the back, with a seat next to her near the window.

Ace nods then walk over to Koneko, who just glances at her and looks back at the front, while Ace has a good look at Koneko.

Koneko is a petite girl around 15 years old with white hair and hazel eyes. At the front, her hair has two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back has a short bob cut. She also wears a black cat-shaped hair clip on both sides of her hair. She is also wearing the Kuoh Academy girls' school uniform, albeit without the shoulder cape. She is also a devil and a nekomata. How do I know that, it is because I am a reincarnated soul.

Koneko turns around and looks at Ace. "You know staring is really rude, pervert," she says coldly, though Ace looks barely affected by her tone.

"Sorry, your just so cute and beautiful that I didn't notice how long I was staring," Ace said with a sheepish smile, while scratching the side of her head. (Author: I actually do scratch my head when I'm nervous, just feels like it itches, or like if it's on fire)

Koneko gains a barely noticeable blush but also is giving Ace a death glare. Though Ace doesn't look affected by it in the slightest.

Ace apologizes once again, before looking to the front, paying attention to the teacher, unaware of what Koneko is thinking right now.

'Why does the hot new girl smell like a boy and a girl?' Koneko thought after she caught Ace's scent, unaware that she thought that Ace was hot.

'But she also has this, strange smell. It's almost like it's reptilian but much more powerful,' Koneko thought while looking straight ahead, pretending to be listening to the teacher, while looking at Ace from the corner of her eye.

'Got to report this to Rias...Maybe not about the boy and girl thing, but definitely about the other smell,' Koneko thought, still looking at Ace in the corner of her eye.
