Hey guys Wizard here sorry for the long wait if you're waiting for a new story but I'm back for my last story on IS because I'm going to Fairy Tail next. But don't worry because I'll be back with another IS story after a few FT ones. Also for those who doesn't know what G!P means it means girl penis and B!V which I made up means boy vagina. Well without further ado. Lets begin. :D (Also I think that this will be around 5-10 chapters.)

BTW I don't own IS because it is owned by Izuru Yumizuru but I own the OCs.

It was a normal day for Ichika in the IS academy. He was one-fourth of the way through with school and after this week it would be a 1 month long vacation. Ichika walked to his class and saw Houki, Luara, Charl, and Cecilia talking to each other.

"Hey guys." Ichika greeted them

"Ichika!" They all greeted back quickly

"So what are you guys planning on doing during the break next week?" Ichika asked

"Well I'm going back to my country to get my IS's data recorded." Cecilia said

"As am I so I will have to leave my wife here." Luara said

"I'm going back also because my brother wants the data recorded for the next IS" Charl said

"I'm going to visit my family so I won't be too far away. What's your plans?" Houki said

"That sounds like fun. I'll probably stay home or go sight seeing." Ichika replied

"Well sounds fun and it has been a while since I've seen the city also." Houki said

Just then the class bell rang and everyone took their seats. Ichika went to his seat in the center front as Yamada-sensei and Orimura-sensei walking in. They began their lessons on intermediate manuvering, weapon use, and the history of the IS. After what seems like hours (it was) the lesson was finally over. Everyone gathered their materials and packed up for the day. Ichika finished packing and waited for Chifuyu to finish packing.

Everyone has known Ichika as a dense person and that he doesn't have any romantic interst. If they were to think that then they are wrong. It isn't that Ichika doesn't have a romantic interest, it's that none of the girls captured his attention as her. Everything that she does captures his attention. From the way she walks, her hair's movements, or simply to the way she talks moves him. That woman he knows he will never win the heart of because it is his sister Chifuyu Orimura. He's been loving her since he started high school. After that day he never saw her as a sister again. Sure he called her 'Chifuyu-nee' a few times but it was to keep up the act. There was only one other person besides him that knows that he's in love with his sister. That person is Tabane Shinonono. Ichika has kept in contact with Tabane since he started school. They talked and he once accidentally let slip. Instead of scolding him or being disguested of him like most would be, she instead encouraged him to persue her. With that being easier than said he still haven't summed up the courage to tell her yet. Ichika also learned that Tabane also loves Chifuyu but there was something that kept her from telling Chifuyu so she decided to not tell her. Ichika wanted to tell Chifuyu andd he knew that if he waited for too long then Chifuyu would meet someone. There were plenty of men out there in the world that would love to go out with his sister. She is the world's strongest woman and the champion for the first Mondo Grosso.

"Ichika" Someone called but Ichika didn't hear them

Ichika was brought out of his train of thought when he felt an impact on his head. He rubbed his head and looked to see Chifuyu with an annoyed look on her face.

"Ichika what are you doing staying after class?" Chifuyu asked

"I just wanted to walk with you like we used to when we were younger. I want us to walk as brother and sister back to the dorm instead of teacher and student. So do you want to?" Ichika asked

Chifuyu was quiet for a moment before she answered, "I'm sorry but I'll have to decline that. The rule is that there cannot be any relation other than student and teacher on campus."

"I understand." Ichika said before running away with some tears threateningn to fall from his eyes

Ichika ran quickly until he reached his room. He opened the door to see Tatenashi in an apron only.

"Oh? Ich-" Tatenashi started but wasn't able to finish as Ichika ran past her and to his bed

He jumped on his bed and buried his face into his pillow as he cried freely. He bottled up the emotions for too long already and it wanted to burst open. All of the things that he has done before was for Chifuyu. It was to prove to her that he was capable of standing with her. All those times she merely nodded her head or gave him a small compliment make him happy by a little and sad times three as much. He could only put on a fake smile and keep his emotions bottled up but this was the final pouring. Everything that he has bottled up has came pouring out and he has no other way to keep them back. He felt his bed push down a little and knew that it was Tatenashi. She placed a comforting hand on his shoulder as she rubbed circles on his back with her other hand.

"Ichika? Are you okay?" Tatenashi asked

"Ye- Yeah. Why wouldn't I be?" Ichika retorted

"I can tell by your voice that you're crying so do you want to talk about it?" Tatenashi asked

"No, it's fine. I just need some rest." Ichika said

"Okay then. Night." Tatenashi said as she went to her own bed

The next few days went without any complications. Ichika was quieter than normal while the girls talked and he didn't make any comments. In class he would pay attention more and get all his work done. This worried his harem because even though he was doing well, he looked like he died. He gotten skinnier, his eyes had bags under them but you wouldn't notice it unless you're really looking for them, and his movements were more sluggish. On the last day Ichika packed his clothes quickly and got on the train to take him back. Before he could enter Chifuyu stopped him on the way there and offered him a ride back. Deciding that this was an opprotunity that he could spend more time with her he accepted.

"Ichika are you feeling alright?" Chifuyu asked without looking to the side

"Yeah." Ichika replied quietly

"Are you sure because you've been doing better in class?" Chifuyu asked

"Isn't that suppose to be a good thing?" Ichika asked quietly

The voice that he was using made him sound so weak and insecure of himself.

"Well yes it is but you're also quieter than usual and you're also skinnier than your normal self." Chifuyu said

"I guess it must be because I skipped eating lunches." Ichika said

"Ichika I'm serious. You shouldn't do that. That's unhealthy for you." Chifuyu said

"Ok. I promise I'll start eating lunch from now on. Also since we're back home you could keep an eye on me." Ichika said

"Sounds good to me then." Chifuyu said

The rest of the ride was in a neutral silence. Neither side talked and it wasn't comfortable nor was it akward so they didn't know that to do. Once they reached home it was getting late and they were both hungry so Ichika made so food. He made something that was quick and easy so that they could finish it and go to sleep. After they were finished the both went to bed and went to sleep. Ichika fell asleep quickly but was woken up by a nightmare that he has been having. It was Chifuyu getting a boyfriend and then the both of them abandoned him. He stayed up for the rest of the night afraid to fall back asleep. He went down to the kitchen to get some water. After he drank a glass he decided to call Tabane since he knew he wouldn't be able to sleep tonight like all the other nights.
