Hey there, so here we have the start of the main story. The club knows what Luffy is and Issei has been turned into a devil. Things are about to get super fun around here, I decided to go from episode to episode. Occasionally we will have the originals ones, then we will do the Ova´s. This will be a long fic if you know what I mean. I hope you all enjoy this one.

At the Hyoudou household.

After explaining everything to his parents, Rias was having a nice breakfast with Issei and his folks. She was sounding so lovely and with no problem whatsoever, meanwhile Issei was looking like he was about to have a heart attack.

''Ok…so ready to go to school? I guess?" Asked Issei.

''Oh no, not now.'' Said Rias.

''Huh?'' Asked Issei confused.

''We are waiting for someone to come here.'' Said her.

''Who are we waiting for?" Asked Issei.

Soon the door got several knocks. Making the Hyoudou´s confused but Rias smiling knowing who it was.

Knock Knock Knock Knock.

''Let me get it.'' Said Issei mom.

Mrs Hyoudou open the door to see a young handsome, black haired, straw Hat wearing teenager right in front of her door.

''hi Issei!'' Said Luffy waving at Issei.

''Luffy!'' Said Issei in shock.

''Oh good, you are here so we can all go now.'' Said Rias.

''Another person that knows Issei?" Asked Mrs Hyoudou.

''Wait a second, kid are you also a friend of my son?" Asked Mr Hyoudou.

'Yes, I am Issei friend.'' Said Luffy making the parents very happy.

''Thank the lord! I thought he would only hang out with those two low life's perverts.'' Said Mrs Hyoudou thinking of Matsuda and Motohama.

''Yes, those two sucks.'' Said Luffy thinking of those two perverts.

''They indeed do!'' Said the parents.

Issei just looked annoyed at that. Yes, Matsuda and Motohama weren't saints but they were his only friends. Right now, he wanted to know what was the deal with Luffy and Rias.

''What is really going on? What are you two planning?'' Asked him.

''We will explain later. Lets go to school.'' Said Rias.

''Hey guys! Are we going or not?'' Asked Luffy a bit impatient.

''Sure Luffy, let's go.'' Said Rias with a smile as she and Issei went to accompany him.

The three soon left the Hyoudou residence, Luffy even waved goodbye to Issei parents because they seemed like nice people.

''Your parents seemed nice.'' Said Luffy.

''What is going on? What are you two planning?" Asked Issei.

''Well…things will be explained very soon. You might be prepared.'' Said Rias with a smile.

''Huh?"' Asked Issei with a confused look.

''You look so weird with that face.'' Said Luffy laughing at Issei confused look.

''You two are giving me such a headache.'' Said Issei.

Later

As the trio approach Kuoh Academy, the students were shocked to see one of the most pervert students hanging out with one of the most beautiful girls and one of the most of talked about boys of the moment. For them Luffy was a mystery, but he already got some kind of following due to his good looks and always being with the members of the Occult Research Club.

''No way! Him with them!''

''Rias-senpai is walking with one the biggest perverts of the school!''

''And Luffy-senpai too! I thought he was a good guy!''

''What are they doing with that disgusting guy?"

''Maybe they are walking with him for pity.''

''What?! That's make´s no sense.''

''Maybe they are doing threesome.''

''Gross! Why would she sleep with any of them?"

''I mean…luffy-senpai aint that bad.''

''Yes, that loser has no qualities while I heard that Luffy-senpai has a six pack.''

The trio soon arrived at the gates of Kuoh Academy, Issei was ready to go towards his class while Luffy and Rias to theirs.

''Ok, have a nice day Issei.'' Said Rias.

''Yeah, see you later.'' Said Luffy.

''You two have something to do with all of this? Isnt!'' Asked Issei.

''No!'' Said Luffy lying as he whistle and looks the other way.

''He is terrible at lying!'' Thought Issei.

Rias just laugh at Luffy´s antique while she decided to leave while grabbing Luffy arm.

''Ok have a nice day Issei.'' Said her.

''Bye.'' Said Luffy.

''Uh…'' Said Issei left very confused.

As the two left Issei to be bombarded with question by his classmates, the Straw Hat pirate had some questions for the red haired devil.

''Why do you want to tell him this stuff later?" Asked Luffy.

''Because its easier and we will have most of the club with us. This way he can absorb everything better, you know better than just throwing at him at once. Do you understand?" Asked Rias.

''Sure.'' Said Luffy not understanding.

''You two!'' Said the serious voice of Sona.

The two turn around to see the Student Council president marching towards them, she had a look of seriousness and overall confusion.

''Hi Sona .'' Said Rias.

''Hey there.'' Said Lufffy.

'You better tell me what is going on? First, we received news of some…interesting news about your club and second we have other business to talk about it.'' Said Sona because she still thought Luffy was a regular human that didn't know about the supernatural world.

Rias just laughs at that and then answers her friend.

''Well you might have to ask me those questions again, because they are bit confused. Also don't worry, we took care of some pest if you wanted to know.'' Said Rias.

''What do you…'' Said Sona confused and then Rias continued.

''We just fought the Fallen Angels last night and Luffy here scared them off.'' Said Rias poiting at Luffy who just smile.

Sona just look at this in shock, so she told the truth to Luffy and he was able to fight off the Fallen Angels? Then he wasn't a regular human like she theorized.

''He knows?'' Asked her

''Yes, he is now part of my club and know all of my members.'' Said Rias.

''So you are also a devil too?'' Asked Lufy to Sona.

''What? You knew because of my aura or presence?' asked Sona.

''No because you are a weird girl.'' Said Luffy all simple and that made Rias laugh.

Sona just had thick mark on her head over that statement, in just a week Luffy has given her such headaches.

'Shut up you straw hat idiot Next time I will have you clean bathrooms for a month!'' Said Sona pissed.

''Ok! Ok! I am sorry.'' Said Luffy scared.

As soon Sona calm down she decided to ask to Rias about her peerage.

''So is Issei Hyoudou your new pawn?'' Asked Sona.

''Yes, he absorbed 7 pawns pieces.'' Said Rias.

''And Luffy is…'' Asked Sona wanting to know but Rias told her right away.

''I wanted to turn him into my knight or rook, but he refused.'' Said Rias.

''Yes, I won't be anyone servant. Even if this person is my friend.'' Said Luffy serious.

''I take no offense on that.'' Said Rias with a smile.

''I won't bother you since it's your business and this deals with your peerage.'' Said Sona a bit confused, but she guessed this was a topic for another time.

''Thank you.'' Said Rias.

Sona then went near Rias and whispered something into her ear.

''However, you now that have him will cause…some troubles.'' Said Sona referring to all the problems that come into being a member of a royal devil family.

''Yes, I know.'' Said Rias in a whisper.

''What are you two talking about?" Asked Luffy confused.

The glasses girl then went back to a regular distance and then told the two some information.

''Well there is no rule that says that a human can't stay away from a peerage, but when it comes to challenges on the underworld he might not participate.'' Said Sona.

''Correct, I will make sure that Luffy stay out of trouble.'' Said Rias.

''Wait, what does that mean?" Asked Luffy.

''And you mister Monkey D…'' Said Sona staring at luffy.

''Huh?" Asked Luffy a bit off, that stare remind him of when Nami gets angry.

''You better not cause Rias any trouble. She has a reputation to maintain and you causing havoc and doing weird shit is not going to help out. Got it!'' Said Sona.

''Ok! I got it!'' Said Luffy scared.

Rias just laugh at that while Luffy took of a deep breath.

''Have a nice day Sona, let's go Luffy.'' Said Rias bringing Luffy to their classroom, arm together.

Luffy then looked at Sona who was still staring at him.

'What is going with Sona? Is she still mad at me?" Asked Luffy.

''No, but she takes the devil rules serious. You being a huge free spirit might clash with what she believes.'' Said Rias.

''Ok, but I won't let her stop me from doing what I can't do. If she is mad, she can send her crew towards me.'' Said Luffy all certain.

''Oh I am sure we will meet them sooner than we expect.'' Said Rias with a smile.

The two soon went to class and just wait until the day was off so they could get Issei.

After class

Luffy was waking up from the class and soon Rias went to talk to him.

''Luffy I need you to get Issei, bring him to the club. I need to go there a little early to fix some things to introduce him.'' Said her.

''Ok, do you want me go alone?'' Asked Luffy.

''Kiba will accompany you. It will be better.'' Said her.

''Fine.'' Said Luffy

''Right, see you two there.'' Said Rias.

''Ok.'' Said Luffy excited to see Issei

''Don't tell him anything until you two arrive in the club.'' Said Rias with a warning.

''Right, right!'' Said Luffy all relaxed.

Rias just smile at that. Luffy carefree and easy-going attitude was something she was really starting to really like.

Later

Issei was just wondering what was going to happen now. If Luffy and Rias would talk to him or some stuff like that. Then the answer came knocking at his classroom door.

''Excuse me, we are looking for Issei Hyoudou.'' Said Kiba coming inn.

''Uh?" Asked Issei seeing Kiba and another person next to him, which turned out to be Luffy.

''Hey Issei!'' Said Luffy shouting out and everyone saw the Straw Hat teen.

The whole class was in shock to see the most handsome boy in the school Yuuto Kiba and one of the most talked one in recent days Monkey D. Luffy, both wanting to talk with the pervert Issei Hyoudou. Of course the two coming around caused a lot of gossip all around.

''Look is Kiba-kun.''

'And Luffy-kun also.''

''They are here to talk with issei!

''No way! They can't be associated with that pervert.''

''Unless they are pervert also!''

''Are you kidding? Look at Luffy-kun has treated Rias-senpai with more respect than most guys would.''

''Not to mention Kiba-kun is her knight in shining armor.''

''Yes, any girl would be lucky to have those two.''

Issei was griding his teeth in annoyance. Girls avoided him like the plague, but for those two they would throw themselves.

''Great, even Luffy has more chance of a harem than I!'' Thought him pissed.

The two soon to greet Issei, who was looking at the two a bit confused.

''Hi there.'' Said Kiba with a smile.

''Hey Issei.'' Said Luffy.

''Hey Luffy, hey you too.'' Said Issei staring at Kiba.

''We came here in behalf of Rias-senpai.'' Said Kiba.

''Yes Rias told us to get you.'' Said Luffy with a smile.

The two soon took Issei out of his classroom, getting a big gasp from most people. Specially Katase and Murayama.

''No way those two are getting that imbecil near Rias-senpai!'' Said Murayama.

''Yes, we need to tell them.'' Said Katase but the two were hold off by Aika.

''Let it go girls.'' Said her.

''Aika!'' Said the two for the glasses girl.

''Look Rias-senpai is no idiot. If he tries something I am sure she will send him away in ambulance.'' Said Aika making the two girls stop in their tracks.

''Fine, I guess you are right.'' Said Katase.

''By the way your party tomorrow is still up.'' Said Murayama.

''Oh yes, I cant wait for it.'' Said Aika with a smile

At the Occult Research Club

Luffy and Kiba soon arrived at the club with Issei. The brown-haired teen first thought was on how dark that club was. There was little light at all.

''Guys! We arrived!'' Said Luffy very loudly announcing their presence.

''oh Luffy-kun, Kiba-kun welcome.'' Said Akeno.

''Hey senpais.'' Said Koneko while eating some candy.

Issei saw the two beauties and was pretty much with a stupid pervert smile on his face.

''Wow Akeno Himejima and Toujo Koneko.'' Said Issei with a stupid smile.

''you know them?" Asked luffy.

''I know them by name. They are two of the most talked about girls in all of the school. Akeno Himejima is said to be one of the prettiest girls in all Kuoh Academy and look at Toujo Koneko over there, she is so popular among boys and girls because of her lolith appearance. No way this club is so popular.'' Said Issei super excited.

''Great, he is a super pervert.'' Said Koneko with a deadpan expression.

''Did I say that out loud!'' Said Issei in shock.

''You did indeed.'' Said Akeno with a smile.

The brown haired teen felt like his chance of getting close to those two were over, however these thoughts went off once he heard what it looked like a shower.

''Why do I heard the sound of a shower?" Asked Issei.

''Yeah, I hear that too.'' Said Luffy.

''Oh there is a shower in the club.'' Said Akeno all sweet.

''Oh ok.'' Said Luffy all calm as he sits next to Koneko.

''No ´´oh ok´´! There is a shower in here!'' Said Issei with big anime eyes.

''Yes, the president likes to take many showers during the day.'' Said Akeno.

''what a great club.'' Said Issei with a glee in his face.

''he is worst.'' Said Koneko while eating her candies.

''Oh come Koneko, Issei is a great guy.'' Said Luffy while eating some of the snacks that were on the table.

''I don't know Luffy-senpai. He doesn't strike me as someone that will leave girls alone.'' Said Koneko.

''I guess we start with the wrong foot. Nice to meet you Toujo Koneko, I am Issei Hyoudou.'' Said him trying to be polite.

''Whatever.'' Said her.

''So cold!'' Said Issei in shock while Luffy laugh.

''Relax Issie, here grab some snacks.'' Said Luffy stuffing his face with snacks.

''There are more where they came from.'' Said Akeno putting some more for lufyf.

''Oh great!'' Said Luffy with his mouth full which made Akeno laugh.

''Oh you really have poor manners.'' Said Issei with a sweat drop.

Then they heard the shower sound coming off and Issei heard Rias voice.

''Akeno I need my clothes.'' Said Rias.

''Yes president.'' Said Akeno brining some fresh clothes to Rias.

''She is coming right after the shower. Oh boy.'' Thought Issei all happy.

Soon Rias came out of the shower with a new girls uniform from Kuoh.

''Sorry for the wait. I didn't have time to take a shower since I was at your place last night.'' Said Rias looking at Issei.

''Not a problem at all.'' Said Issei with a red check smile.

''Luffy I will be back tonight. I hope you were lonely.'' Said Rias to him.

''It was a little bit, but I am glad that you are retuning.'' Said Luffy with a smile.

''Well that's great.'' Said Rias with a smile.

''You two live together?! For real, those weren't rumors!'' Said Issie in shock

''Yes oh and by the way are you ok with me sleeping in your bed again?" Asked Rias.

''Sure, it was kind of fun having someone by my side.'' Said Luffy with a smile.

Issei was now fuming in rage. Living with Rias was one thing but sleeping in the same bed as her was another story. That was a dream for many men and Luffy was living it.

''He gets to see that beauty first thing in the morning every day! How! How did you do that Luffy!'' Thoguht Issei in pure wrath.

''What is wrong with him?'' Asked Luffy confused.

''He is worse than all those perverts all put together.'' Said Koneko making Issei feeling stabbed in the heart;

''I think it's funny.'' Said Kiba with a laugh.

''I guess we can help change him. After all Luffy-kun here has a way to help others, maybe he can help Issei-kun too.'' Said Akeno messing up Luffy hair.

''Even the girls here prefer him! Oh man, I am so left behind!'' Thought Issei all sad.

''Well I guess it's time to get serious.' Said Rias.

''What do you mean?" Asked Issei confused.

Rias and her members soon stand in front of Issei, only Luffy was still on the couch watching the whole thing.

''Issei we welcomed you to the Occult Research Club, but this club is a mere façade. Nothing more than just a hobby.

''What do you mean?" Asked Issei.

Rias then started to explain to Issie the truth, that they were all devils and the woman he saw for the last few days was a Fallen Angel. She explained the concept of ´´hell´´ and what God has told Angels to do with them and what Fallen Angels were, angels that have fell from Heaven. She also explained that she resurrected him, turning him into a devil and her servant and soon devil wings popped out from Issei back.

''Nice wings.'' Said Luffy laughing as he saw Issei sulking.

''Thanks, where are your wings?'' Asked Issei.

''oh I am not a devil.'' Said Luffy.

''What ! Then what are you?" Asked Issie.

''I am from what they say…another universe, I guess.'' Said Luffy all simple.

''Oh ok and…. What!'' Scream Issei in shock.

Rias just took a deep breath and look fondly at Luffy.

''I guess it's time for some longue story. Take a drink, this will take a while.'' Said her.

This is the end for this chapter. I didn't wanted to make a big one to have all about explain to Issei what the club does and what they are. I went bit by bit, they are devils, Amano is a Fallen Angel and now Issei is a devil. It was actually really fun to write this one. I hope you all enjoy and have a nice day.
