At Gremory house

Rias was sleeping alongside Luffy. She was sleeping peacefully while Luffy was pretty much spread like a little kid. She didn't mind all that since the bed was so large that over 10 people could fit there.

She soon open her eyes and see Luffy by her side.

''So it wasnt a dream. That really happen.'' Thought her.

She saw Luffy smiling with that dumb grim even at his sleep. She couldn't help but to smile at that.

''He is so cute.'' Thought her.

After a few seconds of staring at Luffy sleep face the Straw Hat pirate soon awoke. He then saw Rias staring directly at him.

''Huh?" Asked Luffy confused.

''Oh morning Luffy-kun.' Said Rias.

''What are you doing in my bed?'' Asked Luffy.

''Oh I didn't want to leave you alone. So I decided to stay here with you.'' Said Rias.

''Ok, that's very nice of you. Are you sure you didn't have a bad sleep"? Asked Luffy.

'No in fact I had a really nice night.'' Said her counting to hug Luffy.

''Really?! That's good to hear.'' Said Luffy getting up.

Then the straw Hat captain noticed that Rias was with no clothes, and she was pretty much a few inches from his face.

''Why are you naked?'' Asked Luffy a bit cluless.

''Oh I like to sleep on the nude. Aren't you a bit shocked by this?'' Asked Rias with a bit of red in her face.

''No that's ok. Its how you like it so who I am to judge you.'' Said Luffy all simple.

Rias was now a bit more surprised by this response. Any boy would have a heart attack upon seeing her naked while in the same bed, but Luffy was different he was calm and let her be herself. She kind liked this way.

''Well then I bet you don't mind me sleeping by your side every night?" Asked Rias.

''Sure, I don't mind that.'' Said Luffy with a smile.

''Oh that's wonderful to hear.'' Said Rias.

''By the way is there any food around?' Asked Luffy.

''I will tell the servants to prepare our breakfast.'' Said Rias.

''Yeah! Thank you Rias!'' Said Luffy

Luffy was now out of his bed and ready to run towards the kitchen. The chefs need to start cooking fast or there wouldn't be any more food around.

''He has such energy.'' Thought Rias with a smile as she went to put her clothes.

At the dinning table.

Luffy was of course stuffing his mouth with a bunch of food like usual. Rias was just sitting at her chair drinking some tea and eating some food.

''You really waste no time eating.'' Said Rias with a smile.

''Yes, I need food so I can keep fighting.'' Said Luffy

''Oh really, so to fight you need to have a lot of calories?" Asked Rias.

''Yes, I need that in order to get stronger.'' Said Luffy shoving food all over his mouth.

Rias just smile as she drank her tea. Soon one of her servants appeared with something in his arm.

''My lady the uniform has arrived.'' Said the butler.

''Oh thank you. Luffy here it its.'' Said Rias.

''Uh what is this?" Asked Luffy seeing some clothes.

''Your uniform.'' Said Rias.

''Uniform?" Asked Luffy confused.

''Yes, if you want to be in my school you need to use this uniform. It's a ethic thing, you need to be dressed like this in order to stay in school. Sorry for this.'' Said Rias

Luffy saw the weird uniform. It looked like something formal that Nami would forces him to put it.

''So I have to use this?" Asked Luffy.

''Yes, but you can still be with your hat.'' Said Rias.

''Ok then I don't have a problem.'' Said Luffy taking his shorts.

Rias started to blush as Luffy was starting to strip.

''No! You can't do this in front of me.'' Said Rias red.

''Oh sorry, I thought since you were ok staying naked then I though you will be ok with this.'' Said Luffy.

''I do that only when I am at sleep, I dodnt do this at all the time. Go to a changing room upstairs.'' Said Rias.

''Ok thank you.'' Said Luffy.

Rias then saw Luffy going up with the uniform as she was taking a deep breath and continued to drink her tea.

''ALthougth…so far he has a nice body.'' Said Rias a bit red.

A few minutes later

Luffy arrived using the Kuoh Academy male uniform. He looked like a regular student but the main difference it was he had his Straw hat in his back.

''How do I look?' Asked Luffy.

''Really good, but do you think your hat will match with your uniform?" Asked Rias

''No, my hat will be with me no matter what kind of clothes I wear.'' Said Luffy

''Sorry.'' Said Rias with a smile.

''that's ok.'' Said Luffy with his goofy smile.

''Well then lets go to school. Come with me Luffy.'' Said Rias.

''Ok.'' Said Luffy

Rias and Luffy soon got to Rias limo. Luffy spent most of the time amazed on how the limo worked, Rias just let him have a nice time in the car. She was lost in thoughts on how she was going to handle trying to explain to the other factions in school about Luffy

A few minutes later

Rias and Luffy finally had arrived, the driver open the door of the car so the two could get out.

''This is our school Kuoh Academy.'' Said Rias

Luffy saw the huge place. It looked like a cool place, but he felt that it was missing something.

''Sounds cool but everyone looks so calm.'' Said Luffy.

''Yes, in school we need to behave. We have things to do around here if we want to go on with our life's. Just don't cause a ruckus and I can help you out.'' Said Rias.

'So there isn't a fight club or a meat club?" Asked Luffy.

''Oh there is a karate club and a cooking club. However, I don't think they would fit with them.'' Said Rias.

''What about your club?" Asked Luffy

''You can pass there later and you can meet my members later today. After the classes are done we will meet and I will introduced them.'' Said Rias

'Sounds cool! I can't wait to meet them.'' Said Luffy

''Yes, but don't shout that you are a pirate and if you don't know something I can answer for you.'' Said Rias

''So I stay quiet and you do all the talk?' Asked Luffy.

''Correct.'' Said Rias with a smile.

''Just like Nami does.'' Thought Luffy.

''Rias!'' Said a new person with a serious voice.

The two were going towards the gate of the school, however while going there they were stopped by a girl with short hair, wearing the same uniform as Rias and she had glasses.

''Oh hello Sona-chan.'' Said Rias talking with the president of the Student Council of Kuoh, Sona Sitri.

The girl was looking at luffy like he was a criminal. She was expecting him and making sure he didn't brought something dangerous to the school.

''Who is this?'' Asked Sona.

''Oh this is my cousin Monkey D. luffy. He changed school from Brazil to here.'' Said Rias.

''But I am not…'' Said Luffy confused and Rias poked Luffy in the eye.

Ponk

''Ouch!'' Said Luffy in pain.

''Cousin?'' Asked Sona.

''Yes, he is from my father side. A cousin from my father, kind of a long relation but he is still family.'' Said Rias.

Luffy was making his eye feel better and soon tell Rias to never do that again.

''Ok mister Luffy, listen here this is a serious establishment. As the Student Council President, I take my job very serious. If I hear you causing some form of riot or some idiocy I will put my foot down and make you pay for your disobedience. Understood!'' Said Sona all serious.

''Yes!'' Said Luffy scared, those manners reminded him of Nami and he kept having PTSD of all the beat down that he got.

Rias put a hand on Luffy shoulder and even started to massage a little bit them so he could feel a little relaxed.

''Uh…'' Said Luffy confused.

''I guess Sona made a good first impression. Just be good Luffy, I know you like to be free but if it keeps both of us out of trouble then it would be for the best.'' Said Rias with a smile.

''Ok, I promise to be good.'' Said Luffy with a smile.

''Sure, just get inside.'' Said Sona pointing at the school.

The Straw Hat pirate got inside and while he was looking around Rias and Sona were speaking with each other. She had wrote an email to Sona last night while Luffy was sleeping and she wanted to make sure she knew about it before everyone.

''So this is the boy that falled from the sky?" Asked Sona.

''Yes, I still have no clue in which race he is.'' Said Rias.

''You better keep him in check.'' Said Sona.

''Its kind of hard. He is a free spirit, but he can be persuaded as long food is informed.'' Said Rias with a smile.

''Understood in this case you better be ready to have a lot of preasure from students all around.'' Said Sona.

''Thank you Sona-chan. I will keep Luffy in check around here.'' Said Rias.

''Well you better make sure of it. If something goes wrong I will gladly put down him.'' Said Sona all serious.

''I promise that I will do everything I can.'' Said Rias.

Sona just looked at Rias with a cold glare while the red-haired girl still had a smile on her face.

''We will see.'' Said Sona getting inside.

Rias let go of the pressure that she was having. This was a lot to take it but she thought she could handle Luffy and try to managed her Peerage around while dealing with High School drama.

A few minutes later

Rias was walking around and trying to find Luffy. However, it didn't took a minute since Luffy started to shout out.

''RIAS!'' Scream Luffy

Rias and everyone turned to see Luffy running towards Rias with a huge smile. The girl couldn't help to smile also.

''Oh Luffy you got your schedule?" Asked Rias.

''Yes, a weird guy gave me all these papers. I don't understand them but I think I am going to get it.'' Said Luffy.

''Good, this show what classes you will be having by the day. Also show which class you are. Can we see it?" Asked Rias.

''I am in class 3-A.'' Said Luffy

''Oh this my class.'' Said Rias with a smile.

''Great then we will be together.'' Said Luffy.

''Yeah.'' Said Rias.

As the two were speaking and Rias was showing the halls of the school the gossip started. Everyone was seeing one of the most beautiful girls in the school speaking to someone new. Nobody knew who Luffy was but he was already getting the main attention of Rias Gremory.

''Who is that guy?''

''I don't know but he is kind of cute. Like the Straw hat.''

''Why is he with Gremory-Senpai?''

''I am so jealous!''

''Look at him getting all mushy with her!''

''He is hot.''

''Are they dating!''

In the midst of the gossip there was a specific group that saw that scene. It was the infamous pervert trio.

The group was formed of a bunch of virgins who were well know to love porn, hentai and all type of x rated stuff. The girls found them disgusting and the man hated them. The group was composed of Issei Hyoudou, Matsuda and Motohama.

''Hey is that true that we heard?!'' Asked Matsuda.

''Tell me again who is Rias Gremory again?" Asked Issei.

''Look over there!'' Said Motohama.

The group saw Rias with Luffy, acting all friendly with each other and having a good time. The trio were all burning with jealousy.

''Oh man look at that duffous. Getting clear to someone with huge boobs like that!'' Said Matsuda.

''I don't know who that guy is but I already hate him!'' Said Motohama.

''Maybe he is a cool guy, but come on what does he has that we don't?" Asked Issei.

''I heard around that he is a distant cousin from Rias Senpai.'' Said Matsuda.

''Oh so she is into Taboo stuff.'' Said Motohama.

''Come on guys lets be real. Maybe he is a exchange student and she likes ´´tropical´´ things.'' Said Issei already having a porno in his mind.

While the gossip was going at full around Luffy didn't understood at all.

''What are they talking about?" Asked Luffy

''Nothing Luffy. Just ignore them.'' Said Rias.

''Ok.'' Said Luffy.

In the classroom.

The class was full and Luffy was at the front, the teacher was ready to do the announcement,

''Morning class. We have a new student; his name is Monkey D. luffy and he comes from Brazil. Don't worry his Japanese is very good and he is relative from our Rias. Do you want to say something Luffy?'' Asked the teacher.

''Hi guys.'' Said Luffy all simple and everyone laugh.

''Luffy please sit over there. We have a nice desk for you.'' Said the teacher.

''Ok.'' Said Luffy seating at a desk near the window.

As he seat on his desk the teacher started to talk.

''Ok class today we will talk about the fall of the Roman empire and…'' Said the teacher going on with her class.

Rias was trying to pay attention, but she was focusing more on Luffy then the lecture. The boy was playng with his notebook rather than taking notes. She could see him doing scribbles and laughing around.

''He is not even trying to pay attention.'' Thought Rias.

Luffy was just doing some random drawings on his notebook. Thinking of all the adventures that he and his crew were going to have when he returns.

Rias was thankful that the teacher didn't noticed that, she might have thought that Luffy was taking notes but it was great that she didn't saw his notebook.

''I guess school isn't for him.'' Thought Rias.

After class

Rias went to see Luffy who was still scrambling with his notebook.

''So Luffy what do you think of the class?" Asked Rias with a smile.

''I just heard 5 seconds of it and then I started to drawn.'' Said Luffy with a smile.

''Well I would like to take a look later. I can tell help you with homework later, right now we need to leave.'' Said Rias

''What why?' Asked Luffy.

''Is lunch time.'' Said Rias looking at the clock.

''LUCNH! Come on Rias let's get some!' Said Luffy grabbing Rias hand and running throught the halls of Kuoh, looking like a couple.

''Luffy calm down.'' Said Rias with a laugh.

''Where is the cafeteria?" Asked Luffy

''Is over there!'' Said Rias with a smile

''Lets go!'' Scream Lufy

''Ha Ha Ha.'' Said Rias laughing.

Luffy and Rias were looking like a couple in love, the man and women were all just biting their nails in jealous. Specialty Issei Hyodou, he wanted to have a cute chick like Rias to hold his hand and also check out her breasts.

''Man look at that guy! He is with a great looking babe, and I am all alone.'' Said Issei.

''Excuse me.'' Said a feminine voice behind her.

The boy turned around and he saw a cute brown-haired girl.

''AAAAAH! She is so hot!" Thought Issei in shock.

''I am sorry but I couldn't help to overhear you. Don't worry I think you´re cute.'' Said the girl.

''Oh really thank you. I am Issei Hyodou and you…'' Said Issei.

''My name is Amano Yuma.''

So here we have it. Luffy is enrolled to Kuoh and Rias is starting to have a lot of fun with him. He meet Sona and soon he will meet the rest. Calm down, I know the good amount of power that he will released against the enemies. Also Issei appeared and Amano, who knows what will happen next. See you next time.

Also, I know that Akeno would be in Rias classroom, but for this story think that Akeno is 3-B and Sona and her entire Peerage is in 3-C. By the way later I will introduce some OC, I already have designed made and this will be interesting, a hint is that a character will be turned into a devil. I won't tell this.
