Hey there, welcome to another chapter of this fic. Now we are going to see the Familiar Forest and see what is going to happen. I never understood why Issei never got one until much later in the Light novel, of course in typical DxD is a joke that turned out really more of a Deus ExMachina.

This time it will be a little more Original this arc, I feel that a lot of people think I am just copying and paste original DxD and putting Luffy on it. Well, here is the chapter.

At the Familiar Forest

The place was known as the creation of all Familiar, creatures that helped devils in all their tasks and duties. To get a familiar you need to be acquainted and know the creature who comes near you. The place was sacred and really dangerous, not only because without proper guidance the familiar could attack you, but the forest was on the domain of the powerful dragon Tiamat.

At the Tiamat Lair.

The dragon queen was at her throne, just wondering what was her duties today. She wasn't sleep in a while since the meeting of deities, she wanted to know what was the source behind all that mystical power. Before she could do anything else her server Zatouji arrived.

''Lady Tiamat, the devils who will be selecting familiar will arrive soon.'' Said Zatouji.

''Who ae the ones this time?" Asked her.

''Members of Rias Gremory.'' Said him.

''Szierches little sister?" Asked Tiamat.

''Yes, apparently she got three new servants and they all need right familiar to aim them.'' Said Zatouji.

''What are their names?" Asked Tiamat.

''Issei Hyodou wielder of Booster Gear, Asia Argento wielder of Twilight Healing and Lucy Tsumetai half human half yuki ona.'' Said Zatouji.

Upon hearing ´´Booster Gear´´, Tiamat growled annoyed.

''So that's his new holder.'' Said her.

''Uh? What do you mean?'' Asked him.

''Ddraig, the bastard has a new host, and I wasn't informed. I am going to skin this Issei Hyodou alive.'' Said Tiamat.

''Wait my lady, according to miss Rias this Issei has just discovered the Booster Gear for not even a month.'' Said Zatouji.

''So he hasn't awaken yet?' Asked her.

''No, my lady.'' Said Zatouji making Tiamat look tired.

''Alright, we will meet another day. Make sure that they stay in the forest and no near close my area, I am not in the mood for talk today.'' Said her.

''Understood.'' Said Zatouji.

The Familiar Master left the throne room of the Dragon Goddess and went to do his job, meanwhile Tiamat just looked annoyed at the celling.

''Another lifetime Ddraig, when are you finally going to pay me back bastard?" Asked Tiamat.

With Rias and the others.

The group had arrived at the Familiar Forest, even people like Raynare and Luffy were with them. Despite not being devils, they were members of the club and they helped out in several occasion.

''So how does it work here president?" Asked Issei.

''The familiar Master will meet up with us and then help you three find the perfect familiar.'' Said Rias.

''This is kind of nervous, I don't know if I am going to get a good one.'' Said Asia.

''Oh come on Asia, you gotta try. Who knows what kind of awesome creature you can get!' Said Luffy excited.

''Why couldn't the Student Council come with us?" Asked Lucy.

''Because the Forest has a rule, one peerage per month. This way the Familiar Master can guide us all with ease.'' Said Kiba.

''Oh I see, I guess it would make his job much easier.'' Said Issei.

''Are they imported from somewhere?" Asked Lucy.

''No, all the familiar are created here Lucy. From magic or from mythical realms.'' Said Rias.

''Understood.'' Said her.

''Oh! I see you all! Who´s ready to catch them all!'' Said an excited voice belonging to Zatouji.

The group turned their heads to see the Familiar Master, who looked like a bum more than anything else.

''Who is that creep?'' Asked Issei.

''That creep is the Familiar Master of this forest, Zatouji.'' Said Rias.

''Really?!'' Said Issei in shock.

''Wow! Hey old man are you really friend with all these creatures?" Asked Luffy.

''Yes, I´m in constant contact with these creatures. Once I see one of them, I capture them, observe and then release it back to nature. There´s nothing more pleasurable than this.'' Said him,

''Its like catching bugs?" Asked Lucy.

''No! It's nothing like that!'' Said him all pissed..

The club just looked confused at that.

''Ok, I guess that's a trigger word.'' Said Lucy.

''So Rias Gremory, are your new servants here?" Asked Zatouji.

''Yes, please come forward you three.'' Said Rias.

Issei, Asia and Lucy all were up front, and they looked at Zatouji with a confused look.

''Did any of you ever played catch with a creature?' Asked Zatouji.

''No.'' Said Issei.

''Me neither.'' Said Asia.

''Does Pokémon count?' Asked Lucy.

The familiar master looked disappointed and even shooked his head.

''Tsk, tsk, tsk. This is a disgrace! How are we going to help you three find a familiar if none of you know what kind do you all want?'' Said him.

'I do want a familiar very sexy! Kind like the president bat.'' Said Issei.

''I want a familiar that knows how to take care of me.'' Said Asia.

''I want one that helps me around.'' Said Lucy

The familiar master looked a little happier now and felt that he could work with that.

''Oh, we can find familiar like that in here. If you all follow the right path and stay away from certain areas, you will find a bunch of great familiar in here.'' Said him.

''Thanks sir.'' Said Asia.

''You better be good.'' Said Issei.

The group started to follow the familiar master, wondering what kind of creature would he help find for them.

Luffy looked around everywhere, looking for a creature to play with or to goof off. It didn't took long for Rias to notice that.

''I can sense you´re excited to see the familiars.'' Said Rias.

''Yes, it sucks that I can't have one.'' Said Luffy.

''You cha have one if you become a devil.'' Said Akeno.

'Not a chance.'' Said Lufffy.

''Well Luffy just make sure you´re with us all the time, who knows what could be here in this forest.'' Said Rias.

''Ok.'' Said Luffy.

The group soon felt that they were going to off for a while, then Luffy saw an Atlas beetle and it was a big one, so of course he was excited.

''Beetle!'' Scream Luffy running.

''Luffy wait!'' Said Rias.

''don't worry, that area is a safe. He would have to be a master in not knowing his directions to get into a bad area.'' Said Zatouji.

''Honestly with luffy around trouble will find him.'' Said Rias.

''Ara Ara Ara, but this is where all the fun happens.'' Said Akeno.

''I hope senpai doesn't get lost.'' Said Koneko.

''Luffy-kun is a reliable guy, he will know what to do.'' Said Raynare.

''Kids be prepared, we are near the creatures. After this you´re on your own to get the best familiar that you can.'' Said Zatouji.

The three nodded and made sure to not mess up this whole thing.

Issei just wanted to find a sexy familiar, one that would be with him all the time.

''I need to get a sexy one! I gotta find it.'' Thoguht him.

With Luffy

The Straw Hat pirate ran to get the Atlas Beetle, he was going all over the place that he passed down that safe zone of the forest and went towards a exclusive area that people aren't allowed.

''Oh come on! I am just going to get…Got you!'' Said Luffy catching the bug.

Once Luffy open his hands he saw that the bug wasn't an Atlas Beetle, it was a bug familiar that could help you find riches, but for Luffy that wasn't important.

''You´re not an Atlas!'' Said him tossing the bug away.

Upon releasing the non-bug Luffy saw a huge sign in front of him, it was written with big words so even a little kid could see it.

DO NOT ENTER

However, knowing Luffy.

''Oh this must be fun!'' Said him.

Luffy went ahead to what appeared to be just a empty area, because he was standing on a magical portal, if you had enough power on your own you could be teleported to the throne of Tiamat but only a lunatic would be crazy enough to do that.

''Uh what?" Asked Luffy as he disappeared.

Soon Luffy was send to another area bellow the forest, the area where Tiamat resides.

At Tiamat domain.

Luffy looked around to see he was now in a completed different place. Gone was the forest, this place looked like an abandoned cave.

''Woah! So cool!'' Said him.

He looked around, looking for clues or something to find there, but he couldn't find nothing.

''Where am i?" Asked him.

''Who is here!'' Said a booming voice belonging to Tiamat.

Tiamat was in another section so Luffy couldn't see her, she wanted to know who dared to enter her throne room.

''Hello there.'' Said Luffy talking to the echoing voice.

''A human! What is your name?" Asked her.

''My name is Monkey D. luffy and I am going to be King of the pirates.'' Said him.

The dragoness looked a bit astounded by that, she hasn't seen pirates in centuries, and she wanted to know what he was doing there.

''A pirate! Are you here to steal my treasures!' Asked her.

''I mean…I guess yeah.' Said Luffy a bit confused.

Upon hearing that Tiamat began to transform.

''YOU DARE TO STEAL FROM ME!" Scream her now in her dragon form.

Her dragon form was huge, similar to a mythical dragon you would see in a story book. It was red, yellow and with giant claws. Her mouth could make enough fire to wipe out an entire florist and her scales were hard as stones.

''A DRAGON! COOOL!'' Scream Luffy.

Tiamat saw Luffy like if he was a bug and the pirate just prepared to fight.

''Are you here to steal my treasure?" Asked her.

''No! I mean if its meat then yes.'' Said Luffy

''You dare to make fun of me?!' Asked her pissed.

''I don't know, I´m just hungry.'' Said Luffy.

''Did you came to the Familiar Forest on your own?" Asked Tiamat.

''I came here with Rias and my friends! We went to find some cool creatures!'' Said Luffy.

The dragoness just looked at that curious, Rias Gremory brought him? For what purposes.

''So, Rias Gremory is your master, I shall deal with her after.'' Said Tiamat.

''Hey! Leave Rias alone! She did nothing wrong!'' Said Luffy.

''So, you´re willing to fight to protect her?" Asked Tiamat.

''Yes! You attack Rias or any of my friends than you deal with me!'' Said Luffy.

The Dragoness was impressed by that, Luffy was willing to face off against one of the literal Dragon Goddess to protect Rias.

''Very well. I shall fight you, if you lose, I will kill you and I will go after Rias Gremory, if you win I will let you go.' Said Tiamat.

''Ok dragon, you´re on it!'' Said Luffy.

Soon Luffy started to pump his body as steam started to appear.

''What is that?' Asked her.

''Gear Second!" Scream Luffy disappearing.

Then he appeared right in front of Tiamat, punching her right in the check.

Bam

The punch was strong but not enough to beat her, it made her feel a little bit of pain but nothing else.

''Urgh.'' Said her annoyed.

Luffy noticed something when punching her.

''Her skin is not as strong as Kaido. This should be easier.'' Thought him.

''You managed to land the first hit, I give you that. Now it's my turn!' Said her.

Tiamat opened her mouth, and a huge amount of fire magic was emitted and pretty much was trying to burn everything it came in contact with, Luffy started to run as fast as he could.

'AAAAAAAH!' Scream him.

''Go ahead! Die like a man in my flames.'' Said Tiamat.

''No! I am not going to die until I achieve my dreams! If I have to beat you so be it!" Scream Luffy.

''A man willing to fight for his dreams, who admirable. However, I don't see a little guy like you being that strong.'' Said Tiamat.

Luffy just smirk as he put his arm towards his mouth.

''I am just getting started! Gear 4!'' Scream him.

Luffy then got his Gear 4 transformation, bouncing all over the place with haki all over his body.

''Bounce Man!'' Scream him.

''What is that!' Scream Tiamat.

''I hope Rias and the others are fine. This is the first big fight I have in a while.'' Thought Luffy.

With Rias and the others.

Issei found on what he thought was a super sexy Familiar, but it had the appearance of a muscular dude wearing a dress.

''I don't want this thing!" Scream him.

'But she is a good familiar, strong and can grow a lot. Take it kid.'' Said Zaoutouji.

''She looks like a wrestler weaing a skirt!'' Said Issei.

''How lame and sexist can this guy get?'' Asked Lucy.

''I have no idea.'' Said Koneko.

So, this is my idea for this chapter. I need it one of the goddess figures to meet Luffy, I already had Athena and Yasaka meeting Luffy and now its Tiamat turn. I hope you all enjoyed this idea and see how Luffy deals with the Dragon Goddess herself.

Next chapter it's the continuation of the fight and the end of the Familiar Forest. I hope you all enjoy that.

See you all next that.
