"The time has come to wake up…."

"I must be prepared for what's next to come…."

"The Sekiryuutei and the Hakuryuukou…. They will meet once again…."

"This time, I will be there after my long absences…."

"I must make sure they don't cause trouble to the innocent…."

"Even…. If I have to use that Magic!"

*RING RING RING*

The school's bell sprung around Kuoh Academy, telling the students that break time has strated. Our point of view is the class 2B, where reside the 2nd year students. Inside were several students talking to each other about stuff they like. However, our view is a group of three boys who were circulated around one another.

"Hey, did you bring it?" a bald-headed boy ask.

"Heh, of course, I did." a boy with glasses answered the bald one.

"Well hurry up and show it!" yells the voice of a brunette haired.

The glasses one smirks as he takes out a magazine, "Here it is….the new volume." he says with excitement.

The other two put on a grin that only a pervert would do, but that was the case….. These guys are perverts. The magazine is about women doing erotic poses.

"Woohoo! Look at Maya, her tits are huge than before!" the bald one shouts.

"Wow! Look at Sakura, her body is smoother than before." says the brunette one.

"Cammy boobs have grown into a gorgeous E-cup!" the glasses one says.

They continue saying, ignoring the disgusting stares they were receiving from their class, especially the girls. These three, are the infamous Perverted Trio, why? You should know after the comments they say.

The bald boy is Matsuda. The guy is a complete pervert, too much. He could say the word 'Porno' and other things of the woman's body in front of a class and wouldn't care a bit what you think of him. Really disgusting guy.

The glasses one is Motohama. He's a guy that has a perfect photographic memory of girls heist, bust, and butt. A pervert that can say the size of any girls privates parts… Scary.

The last one is Issei Hyoudou. An ultimate pervert, he dreams to have a harem for himself. He is so dedicated to it, he literally will gladly say what his dream is and say boobs like they were the most important thing in the world.

This three, have united together on this remodel school and swore to become harem kings.

"Gah, those three are doing perverting things again, in the class no less." says a girl with brown twin side ponytail with red ribbons

"They are the worst." says another girl with peach color hair. She turns to look at someone. "Hiro, Naruse, can't you do something about them?"

"Yeah, I mean, they at least listen to you two." the twin haired says.

The people they ask this particular question was a young boy with brown hair, with a streak of red color on the side. His school outfit was open, revealing a green blazer underneath. And a beautiful crimson haired young woman with long, flowing hair, two pieces tied in pigtails with black ribbons, her bangs hanging down, framing her face, and her fringe ended just between her dark pink eyes, her school uniform was very tight, making her bosom press against her uniform. The boy had his head against the stool his resting while the girl was writing on her notebook today's work.

The boy looks at the peachy haired with his green eyes, "Katase, Murayama Ise is a lost cause along with those two." he says while scratching his hair.

"Besides, do you two really think they will stop after we talk to them, or that I'll even go next to them?" the crimson girl ask, looking at them with a tick mark.

This two, are Hiro Hyoudou and Mio Naruse, Issei's brother and sister.

Hiro has been with Issei since little, taking care of each other while their parent's work, which consists of them being overseas, they visit them on their free holidays, catching up with their sons. Anyway, back to Hiro, he is the older one by one minute. He just lived up with the fact that his brother is a pervert, but even so, he cares and loves him as a brother.

Mio, on the other hand, was adopted into the family, her mother died while giving birth and his father died of a heart attack. Leaving the red-haired alone with her cousin, but then, Hiro and Issei found them and take them in like sisters.

Ever since then, they all live in the same place since little. Or at least try to since Issei's perviness has caused him to be in bad terms with her. The brunette has apologized to her more times than him saying his favorite word, she does forgive him…. sometimes…. with some sort of punishments. Like burning some magazine porn, making him not say 'Oppais' for a week or making sure that he doesn't do anything perverted for a month… Yep, she's a real devil. That and another problem.

With that said, they managed to live in harmony…. Again, try to.

"Hiro! Look at this!" suddenly, the perverted trio appeared in front of the red-brunette with the magazine, showing an image.

"They have a Double G in here!" Matsuda says, drooling in excitement.

"There as big as two melons combine together!" Motohama says, his glasses shine.

"And there's another pair of them together, rubbing against each other!" Issei finished, causing the girls, except Mio, to walk away from the trio.

Hiro looks at them with an annoyed face. "Why are you three showing this on my face?" he asks them.

"Because you're into this kind of thing!" the all say, causing the red brunette to place his head on the table.

"...What I like is my business, so please, fuck off," he tells.

"Come on! Why don't you join us?! You could dream of having a Harem for your life!" Matsuda yells.

"I agreed, come on Hiro, join us on the road to become Harem Kings!" Issei says, while the other two yell, 'Yeah!' on the background.

Hiro just stood up, "Sorry you guys, while having a Harem is every man's dream, I don't need to be a pervert to do it or have it." he says, giving a serious face.

"Oh come! You practically are like us. Be a man and accept our offer! Been a pervert is the road to becoming a man!" Motohama says.

"Wrong, the road to be a man is when you take her to bed and do it," he says before dropping the truth. "Besides, perverts don't touch breasts, they dream about it."

When he said those words, the trio fall to his knees, crying in sadness. He was right, they never touch breasts, yet they brag about how they feel. Issei stood up with shaking legs, pointing at his brother while crying.

"So what?! You haven't touched or felt one either?!" he yells.

"True, it just shows that I at least will have a girlfriend while the three of you will be virgins forever." he bluntly says. It pierces the brunette's heart like an arrow, dropping on his knees with his friends.

All the girls in the room were satisfying themselves seeing the famous trio getting their dessert. If someone could at least control them for a bit, is Hiro and Mio.

Just then, the trio stood up, still crying and shaking fists. "If we stay virgins, all we have to do is make sure you are as well!" They shout together.

At that moment, Mio closes her notebook with enough force to catch the trio's attentions, "You three are nothing more than disgusting pigs, I still can believe my brother is part of this!" she says, standing up from her chair, her breast bounce at her moment.

"Ah~ Miss Naruse! Your breast are glorious as ever!" Matsuda says, hearts in his eyes.

"Hmm, it looks like they grow up a bit…. They are now 56." Motohama says while observing the chest area.

"Wow! Nice Motohama, I didn't even notice when they grow!" Issei says to his perverted friend.

As they discuss her breast, the red-haired flush in embarrassment quickly using her arm to cover her chest. Just then, Murayama and Katase appear in front of her, kendo sticks on their hands and pointing them at the perverted trio.

"You perverts! Don't you dare talk like that to Naruse!" Katase says, standing on her fighting pose.

"Looks like we have to teach you guys a lesson again!" Murayama says, swing her stick.

The trio dodges the attack and sprinted out of the classroom while screaming in fear as they were being followed by the two girls with kendo sticks, which then raised the number as the trio pass through the classroom door being followed by more students girls with kendo sticks.

Mio sighs in relief before putting her notebook away, "Hiro, let's go get lunch." she asks the red brunette, he turns his head to look at her to answer.

*Growl~*

But, his stomach did the talk for him, causing him to flush in embarrassment, "Yeah...let's get some." Mio tried her hardest to not laugh.

"Come on, we have to hurry before the line grows up." she says, grabbing his hand and taking him with her, causing Hiro to blush at her bold move and small hand, and making the male population in there to stare in anger at him.

They were leaving their room, at the same time another red-haired girl was passing through. She was a little like Mio, but she was little older than her, her hair flow through the air. Her blue eyes make her even more beautiful and her body was as curvaceous, finishing the image. One word to described her, she was an angel that was brought from the sky to be blessed by all men's.

The red-haired pass through the crowd, who stop doing what they were doing to watch her. Before she disappeared into a corner, her eyes meet with Hiro's green ones. Making the red brunette blush at her.

Mio, on the other hand, didn't look one bit happy about this girl gazing at them. She quickly pulls Hiro with her, going on their way.

…

..

.

At the end of the school, the two of them wait for Issei to show up. They always walk home together, but the brunette takes his time to get to them.

"Gah! Where is that idiot?!" ask a very annoyed Mio.

"Chances is that he tried to see the Kendo girls changeup with those two, only for them to leave him to get beat up when they caught them staring," Hiro says, releasing a sight.

Just then, the brunette turns up, "Sorry I'm late!" he says, only for Mio to hit him with her school bag. "OUCH!"

"Where were you?! We have to get home right away you know!" she says with anger.

"I'm sorry, is just that I saw someone beautiful today, and I was thinking of her." the brunette says as they started to walk.

"Really Ise?" Hiro asks, very surprised to hear that his brother was thinking about someone in particular. "Care to explain?"

"Her name is Rias Gremory," Mio's eyebrow twitched at hearing the name, "89-58-90, according to Motohama, she's our senior and the president of the Occult Research Club, apparently she's European, Scandinavian." he says.

('Rias Gremory?...') "Those she has red hair and blue eyes by any chance?" Hiro asks.

Issei looks surprised at his brother, "How do you know that?!" he asks with white plates on his face.

"We pass next to her in the hallway this afternoon." he simply stated.

*Gahkonk!*

Issei jaw drops down, "What?! You saw her up close?!" he asks, which Hiro nods. He started to cry, "Dammit…. Why didn't I stay with you guys…. The chance to see her beautiful breasts up close….. I hate you two so much right now!"

The red brunette puts a hand on his chin, "I will admit…. She did have some great assets." he comments.

"I know, right!?" the brunette asked desperately, "Her huge breasts…. her beautiful crimson hair….. those deep blue eyes…. She's a ba-"

"CAN'T WE PLEASE NOT TALK ABOUT THAT GIRL!?" Mio suddenly shouts, surprising the two brothers, "I would like to not hear a single word that has to do with that girl involved!" she says with an angry face.

"Hey! Don't talk to her like that!" Issei retorts at her, "Saying bad things about her…. For shame Mio!"

She was about to talk when Hiro spoke up, "For once, he is right. Mio, do you have something against Miss Rias?" he asks the girl.

She just puffs her cheeks while looking forward, "Nothing, is just that I felt a vibe on her, I fear that she's one of those that take some boy and use him until she finds another one."

The brunettes blink at her once, twice, thrice…. Issei chuckles before breaking into laughter.

"HAHAHAHA! She's jealous of Miss Rias!" he shouts, walking on a bridge.

"I'M NOT!" she yells with a vein popping out on his face. Suddenly, she felt some weight on her head, turning to see Hiro place his hand on top of her while giving a soft smile.

"Don't worry, I'm not so easy to fall on any girl, thanks for caring though." he says, making her blush at his words.

Meanwhile, Issei changes from laughing to crying out of joy, "*sniff* To think you care about me *sniff* Buawwwwww!"

Mio looks at Issei with a bored face, "I could care less what happened to you, I'm only saying it so you don't get yourself broken by some bimbo."

"How cruel! At least show some concern!"

"Stop been a pervert, then I will."

"Never!"

"Then we are finished here." Mio turns back to the road, before she could walk farther a voice spoke up.

"U-Um e-excuse me!" the trio turn to look at a shy girl, she looks to be at the same age at them, she was wearing a school uniform that is not Kuoh Academy's. She has a long silky black hair that reaches down to her back.

"Yes, can we help you?" Hiro asks this mysterious girl.

"Um…. which one of you is Issei Hyoudou?" she asks.

The brunette blinks before using his finger to point at himself, "Um…. Me?"

"I….I'm Amano Yuuma…. A-Are you… g-going out with s-someone?" she asks, surprising the brunette.

"Uhh… N-No?" he says, getting red in the face. On his head, however, was thinking perverted things.

Yuuma sighs in relief, "That's great." she whispers to herself. "T-Then, w-would you go out with me?!"

"..."

"..."

"..."

"...E….EEEEEEEEEEEEEH?!"

"Y-you mean, l-like a d-date?!" Issei asks, stupefied at what he was asked for.

The girl, obviously, showed signs of embarrassment at hearing those words, but in all that, the girl somehow managed to nod, shocking Issei to his soul.

He immediately recomposes himself, "B-But why?! I haven't seen you before." he asks curiously.

Yumaa fidgets her legs together, "W-well, I-I have been watching you for a while…. So ummm…. W-would you go out with me?" she flustered.

Issei looks in shock, here it was a gorgeous girl, and he was asking him out on a date. No way he's going to let this chance pass.

"I….guess, I don't mind though…. Okay! I accept!" Issei answers, causing the girl to be delight about it.

"I'm glad! Then, what time tomorrow?"

"Huh? Tomorrow?! But, we have school."

"I can be after school. Are you free at that time?!"

"Well…. I have nothing after school, so sure." Issei responds sheepishly.

"Then tomorrow shall be…. I'll wait for you in your school if that's okay, and could I have your number as well?" she shyly asks.

"Y-yeah…. No problem!" he says.

They exchanged their numbers, not to long for it to finish.

"Then that settles it, see you tomorrow Issei!" and with that, Yumma ran off, leaving a love-struck brown-haired boy who waved at her as she disappears. Once she was, he turns around with a happy expression.

"A DATE! DATE! DATE! DATE!" he shouts like a little kid. He turns to look at his brother and sister-in-law. "I got myself a date, and you say I will never have a girlfriend! Suck that one, Hiro!"

Meanwhile, the brown/red brunette looks at his brother with a gaze and the crimson-haired blinks at the display.

"Mio?"

"Yes?"

"Ise just got asked for a date?"

"It looks like it."

"...The level of stupidity and ignorance?"

"The machine is broken, he's a lost cause."

With that said, they turn around and started walking.

"Hey! Don't you guys be chickens and talk back!" the pervert commenced talking.

The other two look at each other, letting a sigh out as they think the same thing, ('We are hearing this for the rest of the week.')

The trio continues walking as they disappear on a corner, at that moment, another girl appears on the bridge side. She had white shirt hair and was wearing a Kuoh Academy's uniform while licking an ice stick on her hand, watching the direction the trio disappear before a giant magical red circle appear that appear next to her.

In a big old building, inside a room that looks like an anti-evil spirit room. There were three figures, one was the girl of before, still licking the popsicle, the red-haired girl that Hiro saw, and a black ponytail haired woman wearing a Kuoh Academy's uniform.

"You were right Prez…." says the white-haired to the red girl as she sits on a desk while looking at the window.

"A spot on maybe?" the ponytail girl says, standing right next to her friend.

"Looks like I did right to set might sight on him." she says while looking at the two of them.

"What now Rias?" the girl known as Rias close her eyes to think her answer.

"Let's continue the watch him. Let's not make our move yet…"

"Won't that be a dangerous risk for him?" the black haired asks her.

"Don't worry, I'll have something to help him… After that is all up to him," she answers.

"All so," the white-haired calls the two's attention. "He was walking with her."

At those words, Rias tense up, "Are you sure Koneko?" she asked to the girl named Koneko who, simply nod.

"Acting like if they were brothers and sister."

"This is troubling…. I didn't expect her to be in this…." Rias says as she bites her finger. "On lunch, I pass her classroom to see how she was doing….. And she walks out with the other boy."

The black haired walks up to Rias, "Do you want me to investigate the boy's relationship with her?"

The crimson haired started to think before answering, "Do it, but careful Akeno, I don't want to ruin our truce." with a nod, the black haired known as Akeno understood.

Rias looks back at Koneko, "Was that boy also with her and the other boy?" she asks.

Koneko nods, making the crimson beauty to sigh, "Just what is she's planning? First, she came to tell us that and now this?"

"Shall I continue watching?" Koneko ask.

"Only at school, right now, I'm going to summon my familiar to watch them from afar." she says before a "puff" happen and a small bat appears before flying out of the window.

"You are dismissed Koneko, good night." she says to the white haired who, nods and gives her goodnight before leaving the room.

Rias now looks at Akeno, "Is getting late, why don't you take a rest Akeno?" she says as she started to take off her clothes.

Akeno nods as she also leaves the building, leaving a nude Rias with only her bra and panties. She walks up into the shower and started to wash her body, her thoughts on 'her' and that boy with her.

Meanwhile, at the Hyoudou Residence, the trio are doing their own things, Issei was in his room, making his homework. Mio was on the sofa, reading a magazine and Hiro was resting on the floor doing his homework as well. And smoke was coming out of the kitchen… wait, what?

"Maria, is the food ready?" Mio calls for someone.

"Almost done!" says a chirpy voice that belongs to a little girl with waist-length, straight, silver hair with two large beads on the sides, wearing an apron that covers all her body, making one think she is naked.

This is Maria Naruse, Mio's cousin. I already said this, but Maria is Mio only blood relative. Like Mio, she has no family except for the red-haired. She has been leaving with the brothers, but she could be….. A big trouble….. Have a look.

Hiro look up at her, and turn red, "Maria! What are you wearing?!" he exclaims.

She hums in confusion before looking down at her cloth, she immediately noticed what's wrong, "Oh?~" she says, an evil smirk appearing on her face. "You like what you're seeing? Should I raise the apron up so you can have a…. better view?" she says raising her apron slowly.

"Maria!" Mio shouted while turning red and throwing away the magazine.

"Just kidding!~" the silver-haired spin around, to show that she was wearing clothes, only that they were small that the apron cover all of it. "Tehehe, did I make your hormones rise Hiro?" she asked the red brunette while swaying her hips.

*Slap*

A book hits right on her face, making her stumble backward, "Jeez, I should have learned from this already." says an embarrassed Hiro. "You damn succubus."

"Bummer…" Maria says, taking the book off her face and pouting. "And here I thought I will get you to do kinky things with Miss Mio."

At that moment, the red-haired grab her face with one hand and started to put pressure on it. "Care to explain what you mean with that, MA-RI-A?" she asks, a dark aura coming out of her.

"Ahhhh! Swooowie Mwss-Mwo, you freaking me!" the silver girl shout, fretting her arms around.

"Hiro, take over the kitchen, I have some business to take care off." she says, taking Maria away.

"NOOOOOOO! Hiro, help meeeeeee!" Maria desperately cries for help.

Hiro stood up from the floor, "Don't go easy on her." he says, walking into the kitchen.

"I won't."

"NOOOOOOO!"

Once the food was done, the four of them were eating on the table, with Maria that had swollen bumps in her head and bandages on her cheeks.

"What happened to Maria?" Issei asks, starting a conversation.

"She said something she shouldn't have said, and face the consequences," Mio respond, taking a bite of her meal.

"I was just trying to give Hiro a reason to please Miss Mio." the silver haired bluntly said. Causing Issei to jaw drop, Hiro to spit out his drink and Mio to almost choke on her food.

"What?! What the hell Maria?!" the brunette shouts, looks like he understood the pro-

"Why Hiro?! You should have used me for it?!" …...Or not, perverts will always be perverts.

"Nope, Hiro-san is better than Ise-san." she says, causing the brunette to go all four on the floor and began to bag it.

"Why?! Why is has to be him?! Is it because I don't have muscles?"

"That has nothing to do with it." the red brunette told his brother.

"You know what, it doesn't matter anymore because tomorrow, is going to be the day I become a man!" Issei stood up with fire in his eyes.

As the two older ones grunt in annoyance, Maria bent her head in confusion, "Why is that?" she asks.

The brunette looks at her with red cheeks of perviness, "Tomorrow I have a date with 'My Girlfriend!"

"...Hiro?"

"Yes?"

"Did Ise had a hit to the head or something?"

"Not you too!" Issei yells at her.

"Sorry Maria, but his right," Hiro answer her, causing the silver-haired to gasp in shock.

"No way! For real?!" she says as she looks at his step-brother. "Are you going to introduce her to us?" she quickly asks.

"Maybe if I do good on our date." he says, sitting back in his chair.

"Oh! Oh! I have some tips for you!" Maria says with shining eyes.

"Really?! I could use some recommendation!" the brunette says.

The two of them finish eating and immediately left for the silver loli's room. While Hiro and Mio finish eating.

"...Maybe we shouldn't have let him talk." Hiro says, standing up from his chair.

"Too late for that," Mio tells him, standing up from his chair, and letting out a yawn. "Yawn… I'm getting sleepy," she says, stretching her arms. She gets up and started to walk away.

Hiro started to pick up the plates and move to the kitchen, where he began to clean the plates. When he finishes one, he was about to grab another one when he felt someone next to him.

"Huh?" he says, looking at his side to see Mio cleaning a plate. "Mio? Didn't you say that you're sleepy?"

"Yeah…. But, I can't let you clean all the plates on your own," she says, placing the clean plate on top of the first clean plate. "Besides, those idiots always leave you to do this."

"Can't argue with that." he says, putting a clean plate on the tower of plates.

"...Hey." the red brunette turn around to see her step-sister. "Do you remember the day we meet?"

Hiro snorts, "How can I forget?" he says, "If it wasn't that I received a slap to the face, it would have been a nice one."

Mio becomes red, "That was your fault!"

He turns to her, "Well, excuse me, but how was I supposed to know you were in the bathroom at that moment, I didn't see the 'ON USE' sign on it."

"Why didn't you knock in then?!"

"Why didn't you locked?"

"Tch! A-anyway, about our first meeting…." she started before trailing off

"Yeah?"

"Remember when you hear our story, and that you would take responsibility, even though you're not older than us?"

Hiro looks at her in confusion as to is she bringing this back, "Yeah, and?"

"Well….. I never properly thank you for it," she says as she looks him up. "So, thanks for becoming my brother."

The red brunette stops washing the plates and looks at her, giving her a soft smile, "Don't worry about it, right now, we are family, I will always be here for you."

Mio blushes at his words, "T-thanks…." she looks down and started to fidget her feet together.

Hiro, knowing her for a long time, knew she needs to say something else, "Anything else?" he asks.

The crimson haired, still red, looks at him, eye to eye, "W-well…. I…. I would like one more thing from you."

"Hm?" he hums at her.

"I…. want you to be by my side forever….Big Brother," she says.

At those words, Hiro had bloodshot eyes looking at her, surprised to hear her call him 'Big Brother'. ('To call me that….. She's serious?!')

Of course, she became a tomato by calling like that, looking at her blushing mess, Hiro just gives her a soft smile again.

"Sure," he says, walking up to her, and wrapping her in a hug, causing Mio to be surprised by this. "I will stay by your side forever."

Her pink eyes look at his green ones, she could see that he means it, he always have….. which cause her blush while smiling at him.

"Thank you," and with that, she hugs him back, "And you better keep it, or I'll kill you a hundred time." she says, hugging him like if tomorrow would be the last day she sees him.

"Got it, Princess." he jokes to her, "Now, this noble servant of yours will continue washing the dishes." he says, realizing her, and moving to the sink.

"Then, as my only servant, I refused to let you finish alone since we live in a normal house." she jokes to him back.

They both chuckle at each other as they continue cleaning the plates, not noticing the red bat watching their movements from the light pole into their window.

As they continue with their daily life, little did Hiro and Issei knew that their life will change tomorrow.
