AN Okay, time for the next Oppositeverse fic! I did the Rosario+Vampire one first because of its connection to this one. Also for anybody who has read it before reading this one, please keep in fact that these fics are part of a shared universe so the OC main character of Humans to Vampire will not be a rip off of Tsukune who is in the fic. Sure his background is slightly similar, but he is in fact much different. So please give it a chance and don't judge it from its first chapter.
I don't own Monster Musume

Chapter 1

"Good bye Kishi-kun!" a teenage boy called out as he headed towards his school bus. The boy he called out to was standing there smiling sadly as he watched his brother head off to begin his second year of school. This boy was Kishiko Narasu. Like his brother, he is a short individual, stopping at 4'8. He had black hair in contrast to his brother's own white hair. He had blue eyes like his brother though and an almost child-like innocence even though he was 15. He was wearing a long sleeved black shirt with blue jeans and a normal pair of shoes. He had on a necklace with a charm of a fox on it and skin so pale, a vampire would be jealous.

"Good bye Yoshi-niisan! Have a great second year of school! Tell my future onee-chans I said hi!" Kishiko yelled back to his brother who blushed, but smiled and nodded his head. Kishiko and their parents continued to wave until the bus had pulled away. The second it did, Kishiko's hand fell to his side as he turned and walked back to the car. His parents happily chatted behind him as they followed. Kishiko wasn't up for talking with his parents.

The three got in their car and headed back home. Kishiko sighed as he relaxed in his seat. Memories of playing with his brother when they younger began running through his mind. After coming home from Yokai Gakuen at the end of his first year, Yoshi seemed to be more concerned with seeing his new friends again than he was with hanging out with his brother. Kishiko figured that his brother would make new friends at his new academy, but he never thought that his brother would stop wanting to hang out with him.

Whenever he asked his brother if he wanted to go to the mall or hang out at the park, it was always the same answer, "Not right now, but maybe later." That later never came though which began to upset Kishiko. He knew that his brother wasn't purposefully ignoring him, but he had thought they always would be best friends.

"I guess nii-san has a new best friend..."

Kishiko bowed his head to the side as he waited for his family to reach the house. His attention was caught though when his father told him some news that he was hoping to not hear.

"Kishi-kun! Kaa-chan and I are going on another 'business trip' like last year when your nii-san headed to his academy. We expect you to be on your best behavior and attend your classes like normal alright?" His father questioned him.

Kishiko groaned into his hands, but told his father 'yes' while silently wishing that something would happen that would keep him from being alone all year just like what happened last year after his nii-san left. He reached over to a small pocket on the driver's seat and pulled out his hidden game console and began playing it. He heard his parents begin talking to him again, but he ignored them in favor of his game. They were leaving him after all, so why should he listen to them?

Kishiko began tapping his fingers at intense speeds which catch any normal person offguard. He began smiling as he passed an enemy on his game and continued to the end level only to be confronted by an optional boss. Kishiko immediately tapped the x button to agree to the option to fight. His parents sighed as they gave up on trying to speak to him. Kishiko smirked at this.

Kishiko kept playing his game while his parents continued to speak about their upcoming trip, something that Kishiko mentally groaned about in his head. He pressed the home button to go back to the home screen and then pressed the internet app. He began looking up random videos and read some information on upcoming games.

"I'm definitely getting the Infamy 2 game when it comes out. Hm...oh! They're making a Task X 3! Sweet! Hm... the new visual novel just came out...maybe I'll grab it after kaa-san and tou-san leave. Hm...hm I just got a notification."

Kishiko finished his thought as he looked up at his parents and saw that they weren't paying attention to him which wasn't new. He reached over and grabbed his pair of headphones. After plugging it in, he placed them on his head and then pressed the notification that had popped up. Suddenly, his screen was alit with forms surprising the boy who let out a quiet gasp. Luckily his parents didn't hear him. The boy began scanning the forms that had covered the screen of his game console.

"The Cultural Exchange Between Species Bill? Wait...that was the bill passed when the government revealed the existence of extra-species shortly after nii-san got home. Weird coincidence now that I think about it, but that doesn't matter at the moment. Why am I getting a form about it in my notification box? Hm...it says if I agree to these terms and sign my name...then an extraspecies can come and live with my while I act as their host family. Hm the terms...these seem reasonable."

"Should I sign up though. Kaa-san and Tou-san would be angry if I signed up without asking them. Then again, they left me by myself all year last year just to go and enjoy themselves even if they said it was a business trip. They're doing it again this year...plus I have no one at home, at school, in town...maybe...maybe I can get a friend this way. Maybe I can be like a nii-san and get a new best friend. I mean, I already lost nii-san as my best friend so I guess I can get a new one."

Kishiko pondered about what he should do when his father's voice caught his attention. "Listen Kishiko-kun, your kaa-chan and I are leaving tomorrow. I know that seems pretty early since we didn't leave until a month after Yoshi headed off to school last year, but our crui- our business trip sets said tomorrow," his father told Kishiko who immediately made up his mind.

He grabbed his stylus, clicked yes on the boxes and then signed his name on the form before pressing submit. After he finished, he smiled and relaxed in his seat. He did it. His parents didn't have to know until it was too late. He was going to have a new friend!

Kishiko closed down the rest of the forms and went back to searching the internet for more information on upcoming games only to receive another notification. He immediately clicked on the notification box and read it.

Hello Narasu, Kishiko,
Thank you for signing up for the Cultural Exchange Program! We are excited that we have another person willing to house an extraspecies!

The extraspecies that is coming to live with you will arrive in two-three days. Within that time you will meet with your coordinator, and our workers will arrive to customize your house in the case that you house a large extraspecies. Your coordinator will make sure that you are suitable to be a host family for the extraspecies as well as tell you any extra rules that you need to know. They will continue to check on you while you remain a host family.

Once again, we would like to thank you for signing up, and we are sure your extraspecies will be happy about it to!
Thank you,
The Cultural Exchange Program Government Division

Kishiko's smile threatened to split his face in two. For the first time since his brother began to go to Yokai Gakuen, he felt truly happy.

The Next Day

Kishiko yawned as he began to open his eyes. He turned his head and saw that it was around 10:30. He sat up on his bed and stretched his limbs.

"Man, that was a good sleep. I better go tell kaa-san and tou-san bye before they leave," Kishiko muttered to himself as he got out of bed. He changed out of his pajamas and headed down the hallway after leaving his bedroom. He walked into the kitchen, expecting to see his parents sitting there eating breakfast, but the sight that greeted him enraged and devastated him even more. The kitchen was vacant and a note was sitting on the table.

He walked over and picked the note up. He read through it and felt his emotions surge more and more.

"They already left! And they didn't even tell me bye! What?! Am I really that unimportant to them?! Ever since nii-san began to go to that high school, they have began to treat me like I'm some resident living in an apartment. They barely talk to me! They left me by myself all of my final middle school year! They didn't even show up for my graduation for goodness sake! They didn't call on my birthday...at least nii-san did...even if it was rather late when he did. Am I really that unloved?...Fine...I see how it is. I'm glad I signed up for the exchange program. Who cares if they remodel the house! They deserve it for abandoning me!"

Kishiko tossed the note in the trash can before heading over and fixing a bowl of cereal. As soon as he sat down to begin eating, he heard a knocking on the door. He stood up in confusion as he wasn't expecting anybody to visit today. Plus, he needed to go and gather his school supplies since school began in a few days for him. While his nii-san's academy started this week, his school started the following.

Kishiko headed to the front door. He opened the door and felt his cheeks heat up at the sight of the woman in front of him. She had to be from the government. Her clothes practically screamed government agent. She had long black that framed her face perfectly while wearing a pair of sunglasses. Her suit hugged her curves perfectly and the black pantyhose she wore showed off her legs greatly. She was rather tall to the point that he didn't even reach her chest in height.

The woman looked down and gasped which startled Kishiko.

"W-What? What's wrong miss?"

The woman continued to stared at him which began to unnerve the poor kid as he glanced back and forth as he felt his natural nervousness begin to over take his body. He was about to question her again only to be tackled to the ground and pulled face first into her large, soft bust. He felt her rub her cheek on the top of his head while settling on top of him making his whole face light up red.

"OH MY GOD! You are the most adorable thing ever! I have never seen someone as cute as one! I can't believe it! I've been all over the world, and no one has come even close to your level of cuteness. I mean there was this one kid in Karakura Town a few days ago, but he wasn't as cute as you! Let me ask you an important question, do you have a girlfriend? Are you single? Like older women?...Are you straight?" she pulled back and looked at his blushing face making her squeal, "Oh good you are straight! Oh that red face is so adorable!"

Kishiko felt himself get even more embarrassed than before. No girl has ever shown interest in him before thanks to his short stature and shy nature. He was a subject to bullying when he was younger by both genders except for when Yoshi was around since they were scared of him. Even though he wasn't much taller than his younger brother, Yoshi use to exert an intimidating aura whenever his brother was being picked on. That was something Kishiko really respected about his nii-san.

"U-Um...are you my c-coordinator?"

The woman finally quieted down as she heard him speak. She looked down at him with a slightly flushed face as she absorbed his question. Within a second, she was off him and on a seat in the living room with a serious look on her face.

"Yes I am. Sorry for...what just happened. I would promise that it won't happen again...but I can't make that promise. Anyway, I will be your coordinator from here on out. Call Smith-san...or Smith-chan...hell you know what just call me Kuro-chan! Anyway, I have come to inspect the house as well as the host family to make sure the extraspecies that will be living with you will be safe. Do you mind getting the rest of your family down here so I can speak with them?"

Smith smiled as she finished her request. Kishiko sweat a little at this. He knew he had to tell her the truth, but if he did than he might not get to become a host family. Then he would be alone...

"Um...I have a nii-san, kaa-san, and tou-san. My brother is going to a private school called Yokai Gakuen," Smith's expression sharpened at the mention of the school as she checked her papers on Kishiko again, "And my parents went away on a cruise this morning before I woke up. So I'm the only one here...I know I'm under 18, and it's probably not allowed, but please I beg of you let me be a host family. I was stuck all by myself last year! I had no one here. My nii-san is my best friend, and he left me to go to his first year of high school. My parents were so overjoyed about it that they decided to go away on vacation and left me by myself. I had to learn how to do laundry and cook thanks to them! While I appreciate the fact that I know these skills now, the fact that I learned them because I had to survive using them does not make the situation any better."

"I know how to take care of myself, and I'll learn about whatever species that I house to make sure they are comfortable living here. I promise to look after them and myself. I just want companionship since I have no one right now. So please Smith-san, please let me be a host family."

Kishiko got on his hands and knees and began bowing to a shocked Smith. She just looked down at him before smiling and removing her sunglasses. She bent down and put her hand on his shoulder causing him to look up at her.

"While a host family usually requires someone of the age 18, I think I can make an exception this one time. However, because of your age, I'll have to visit more often to check on your exchange student. So if I were you, I'd learn to make coffee. While I can't speak much about your parents or sibling, I will promise you that you will not be alone anymore. I'll have the workers here within the hour and your exchange student will arrive by tomorrow at the earliest," Smith finished with a smile on her face.

Tears formed in Kishiko's eyes at this. He suddenly sprung forward and hugged Smith tightly around the waist while sitting on her lap. Smith hugged him back tightly while looking away with a large nosebleed. "Shota power!" Smith relished in the hug before she had to go as she knew after bringing his liminal to his house, it might be awhile before seeing him again.

Kishiko eventually let go and stood back up on the ground missing the pout that popped up on Smith's face. After talking for a few more minutes about the rules of the Exchange, Smith left which left Kishiko by himself. He sat there in silence. The feeling of silence began to grow larger and larger as it began to surround him. He closed his eyes as he began to take a large breaths. "It's going to be okay. Just one more day, then I'll never have to feel like this again," Kishiko muttered to himself as he rubbed his forehead.

He went to his room after putting a note on the door for the workers to come in when they arrived so they could begin working. Kishiko couldn't wait to meet his future housemate so he had decided that he was going to go do something that he did an awful lot last year. He was going to sleep the day away. It helped the time move by quicker, and it kept him from dealing with small bouts of depression and sadness.

"Tomorrow...tomorrow is when everything changes for the better."

And that is the end of the first chapter! Surprise everyone! The main character of the Monster Musume fic is the younger brother of the main character of the Rosario+Vampire fic! Bet you didn't see that coming did you?! So, I'm sure that anybody who has also read the R+V Oppositeverse fic can see that the time is different between these two fics as in this fic, Yoshi is heading off for his second year while in the R+V fic, he's beginning his first year.
Well, the R+V fic starts a year before the rest of the Oppositeverse fics. Yes, it will eventually catch up with the rest of the fics, but until then don't expect too many crossovers with the R+V fic as I don't want to have to come back and look for anything that I will have to write around in the future.
Anyway back to this fic, in this universe the Cultural Exchange Between Species Bill is still fairly new. It came out shortly after Yoshi's (R+V Oppositeverse OC) first year at Yokai Gakuen ended. Thanks to events stemming from that, the government decided to reveal the existence of monsters. The academy itself is still a secret to normal citizens though for...reasons that will be revealed in time.
Now, Kishiko is much shyer than his older brother and he is shorter so he is a subject of bullying like Shiro from The Opposite. He also suffers from constant loneliness thanks to Yoshi...in a sense even though it was unintentional. The brothers will eventually...'talk' about this in the future, but yeah.

Now I'd like for you all to give me suggestions for his harem which will be a Mass Harem. I will accept OCs if they are creative enough. I already have a list, but it is subject to change depending on everyone's requests. The only thing I will not change is the pairing of Kimihito and Miia. Those two will be a couple, and Miia will be Kimihito's only extraspecies housemate. Oh also, if people want a monster girl from monster girl encyclopedia, then if I like her enough I will add her, just give me a bio.

Also yes, Smith is in the harem. Heh I made her a shotacon :P
