(A/N: here is how Lucas looks post isekai, he is about 7 feet tall because of the High Human genes combined with the soul contract with his familiars)

(Now onto the story)

The chapter beggins in Brazil, specifically a generic city from the state of Rio de Janeiro, in it we can see a tall late-teenage boy walking home after buying some food for himself.

This boy is called Lucas Marvelous, an autistic boy who had just finnished high school and had no idea on what to do with his life from this point on as no university course or conventional carreer intrested him, he wanted to work with something he could actually enjoy.

While walking through the streets, Lucas didn't noticed that an out of control mail van was approaching, hitting him and taking his short life. It was a tragedy, blood everywhere, fired people, late delievries... and in his last moments of counciousness, Lucas said the only words he could think of.

-Dança Gatinho Dança!

But, if life is full of surprises, who could tell death was even more? Lucas opened his eyes, and saw himself at a weird, but familiar, place, with a fully black colored sky and a flat ground with a chessboard pattern.

-Wait... this is one of those isekai rooms- Said Lucas reckognizing the style of the place and situation he was in. -Am i going to reincarnate at a Japanese show?

Suddenly, a feminine voice behind him surprised him by saying something.

-Well yes thanks for making my job easier by figuring it out- As Lucas looked to see who said this, he was met by a native-Brazilian looking woman. -I am Rudá, goddess of love from the Tupi religions, and you have been chosen by me and my father, Tupã the god of thunder, to become a Champion, a person choosen by one or more god to be reincarned in another world after their death, you will get three wishes.

Lucas took a few minutes to fully absorb all of the information, but when he is done, he starts to think about what his wishes are going to be.

After a while, he had fully decided so he turned his look to Rudá and told her his three wishes: first, a customized RPG system inspired by the many isekai stories he had read and written; second, the power of Gilgamesh's Gate of Babylon, but with weapons from many fiction worlds; and lastly, he wanted a set of unique familiars based on the Jurassic Park and Godzilla franchises.

Rudá nodded her head, and a pink glow covered her hand as a pink magic circle appeares below Lucas, and in the next second, he had been sent to the DxD World.

When Lucas woke up, he was laying on a large bed with black sheets inside a huge bedroom with black walls, a last gen gaming pc, many consoles, games, novels and manga.

When his memories came back to himself, Lucas saw a dark red screen with silver letters float in front of his face.

[Welcome Player, i am your System. Downloading new life information]

In a matter of a second, flashes of Lucas's life in this world started to come to his mind. This new world was mostly based on DxD, while having some elements from other media mixed in.

Lucas's life in this new world was... intresting to say the least, as he was still born in Brazil but one day, his family died so he started living alone until he found out about the death of a distant relative and, as their last living direct relative, Lucas inherited the wealth.

When Lucas was about ten in this new life, he was sucked into a rift to a space with many different eggs, and when he touched the eggs they hatched into his new familiars.

Three years later, Lucas awakened an incredible power, the sacred gear of the King of Heroes, the Gate of Babylon.

Going back to when Lucas received the inherited wealth from a distant relative about a week before the present, he moved to Japan, and now is living at Kuoh Town.

'My stats seem rather high for a Level 1, i assume it is because of the High Human race' Said Lucas in his mind. 'And the fact that Intelligence, Wisdom and MP are so much higher than the other equivalent stats must be from the Blaster class'

'Wow, those are a great starting set of items'

[Once you get to a level high enough to unlock the Gacha system you will be able to obtain more items]

'Thats cool. By the way, how do i check an summon my familiars?'

[To check your familiars you must focus on which familiar you would like to visit, that will let you access the Familiar Spaces of your mindscape. As for summoning, you can only do that to familiars who's respect you have given names to already, as it requires you to extens your hand and call the familiar's name]

'Allright, i think that's all for now, i talk to you later system'

After that conversation Lucas looked at a drawer he had on the side of his new bed, seeing his phone, a lot more modern than the old Samsung he had before dying, but luckly the password was still the same.

He quickly installed all of the apps he considered more important before sitting down on his bed in lotus position, he had decided he would try to gain respect of some of his familiars, deciding to start by the Velociraptors.

He started concentrating into them and soon he found himself at a place simmilar to the habitats a carnivorous of relatively small port would be contained in a Jurassic Park game, except it was much larger.

Looking around, Lucas saw four figures had detected him, and assuming they were the raptors he called them to approach him.

Suddenly, Lucas was surprised by the view of four half-human half-raptor girls, one had a blue color scheme with short hair going down to her chin/neck level, the second one had a green color scheme and her hair was tied in twintails, the third was also green and her hair was simmilar to the first one's, and lastly the fourth one had a brown color scheme with a slash scar on her face and her hair tied on a ponytail, Lucas imediatly questioned the system about why the raptors looked so... humanoid.

[When the familiars bonded to the player, part of their dna was mixed with yours so they all gained a humanoid looks while growing to their adult forms, and since they were all females they ended up looking like anime girls]

[Skill Obtained: Harem Aura]

[Message from Rudá: 'Hey Lucas, i hope you liked the surprise, don't worry the skill won't force any of the girls to like you, it will just boost the right traits to build a harem. I knew you had been lonely so i gave you a little push']

The raptor girls looked at Lucas, they hadn't seen their master ever since they were hatchlings as he didn't know how to summon them or access the familiar space, and they were very pleased with how he looked (after isekai Lucas looks like a human version of the fossil pokemon Tyrantrum, fitting for a king of dinosaurs).

The raptors were some of the most friendly of the 23 familiars Lucas had, and definetly the friendliest of the carnivore ones, so they were especially happy to see him after so long.

-Master! Is it really you?- Asked the one with the twintails.

-Of course it's him you dumbass, he is the only human who could enter here- Said the brown one.

-You have a point but... how did he get here?- Asked the green one.

-Quiet you three. Let's just let Master explain- Ordered the blue one, seemingly the leader of the four raptors.

Lucas then greeted the four girls and proceeded to explain about how his mind had been basically fused with the mind of his previous life, and now he had those new powers and that's how he learned to enter the Familiar Space. The Raptors were surprised, but eventually accepted that he still was technically the same Lucas they met as hatchlings, only now he had a second set of memories and both fused minds.

Lucas then proceeded to give each of the raptors a name so that they could get summoned at any time he wanted, the names being Blue (for the leader), Charlie (twintails), Delta (green) and Echo (scar), the raptors loved the names and pounced on Lucas to snuggle him for that, and as the Raptors fully accepted him as their master, a new message appeared.

[Raptors Unlocked!

New Skills Avaliable:

. Velociraptor Form + Velociraptor Hybrid Form

. Steel Magic (from Blue)

. Poison Magic (from Charlie)

. Plant Magic (from Delta)

. Supersonic Screams (from Echo)

All Skills have been learned]

'Wow' Thought Lucas. 'So not only do i get the magic abilities of each familiar that accepts me, but i also get the ability to transform into their species'.

[Infact, the stronger is your connection with a familiar, the stronger both of you get, and simmilarly their power grows alongside yours]

Lucas spent the next minutes playing and sparring with the Raptor Squad in order to get used to his Velociraptor form and new skills.

After some time Lucas left the Familiar Space and grabbed a pair of sunglasses, his wallet, phone and keys on his drawer, put the sunglasses on to protect his eyes from the sunlight and went outside to take a walk around Kuoh Town to get to know the place propperly, since next monday was the day he was suposed to get into Kuoh Academy.

While walking around, Lucas got distracted and bumped into someone who fell down due to his higher body mass, he noticed it and helped the person get up, he noticed it was a brunette girl who had a strange simmilarity to Issei, so being curious he decided to use Appraisal on her.

[Name: Isami Hyoudo aka the Red Dragon Empress

Level 1]

The rest of the information is not really relevant so he stood there for a few seconds surprised that seemingly some characters had been genderbent.

Meanwhile on Isami, she had a slight blushing due to, in her standards, this stranger looked better than any guys she had met in her life.

-H-hi, sorry for bumping on you- Said the host of Ddraig. -And thanks for helping me get up. I'm Isami by the way, Isami Hyoudo, but my only friend Aika just calls me Isa.

-It's allright, no prob- Said Lucas with a kind smile, in his old life he would probaly have let his thoughts go out of control while speaking but thanks to Gamer's Mind this was not the case here. -And the name is Lucas, Lucas D Marvelous, i moved from Brazil about a week ago.

Lucas and Isami kept talking for a while, the brunette taking Lucas to get to know the town since she had lived there her whole life, with Lucas being able to confirm that just like her original counterpart, Isami was actually a great person if you don't judge her just for being a pervert, he never understood why people hated Issei for that even tho at least he never perved on a girl too young for him, unlike Meliodas, Jiraiya, Master Roshi and even Sanji in the movie Z (Kid Nami) and Whole Cake arc (he was 21 and Pudding 16 so it was officialy beyond the 4 year age gap limit of most ages of consent below 18), all of those being loved by the same hypocrites who hated Issei.

Now that he thought about it, Lucas made a personal goal of his to kill Sanji if he ever gets the chance, adding him to a list with characters like Riser Phoenex, Jacques Schnee, Pink Diamond, Kai Greene, Valentino, Stella Goetia and many others from many different worlds.

Anyways, after spending a few more hours together, Lucas and Isami officialy became friends, even switching numbers.

Since it was getting dark, Lucas offered himself to walk Isami home, which she accepted, Japan may be in theory one of the safest countries, but there were still fallen angels potentially aiming to kill Isami due to her hosting the red dragon emperor of domination, Ddraig Golch.

Unknown to Lucas, in Isami's bisexual pervert mind she was already developing some fantasies about him, usually acompanied by some hot girls she knew from school like her friend Aika Kiryu and their senpai Rias Gremory.

Well you can't really blame her since she had never really had a guy be so friendly with her. Sure she was a pretty girl, but when you study in the same academy as Rias Gremory, Akeno Himejima and others it gets kinda hard to get attention in comparisson, and even most other girls found her creepy so her only friend was Aika, who was arguably an even bigger pervert than Isami.

After taking Isami to her place, Lucas started walking back home while humming the melody of the classic Jurassic Park theme, as he walked he noticed a presence following him, one of the perks of having both Gamer's Mind and Appraisal, and as he turned around to face whoever was following him, he saw Generic Fallen Angel, seemingly following him to kill him to stop his sacred gear from being used by anyone besides themselves.

'This may be an oportunity to get some good old XP' Said Lucas in his mind as he smiled sadistically. -Well well well, it seems like a little buzzard came after a dinosaur.

-You are a brave one- Said the fallen angel summoning a light spear to his hand. -If you don't resist i will give you a quick death.

That comment caused Lucas to laugh like a madman before staring at the fallen angel.

'Appraisal' Said Lucas in his mind finding out the fallen angel's stats were pathetically low, even compared to him at level one. -Well, too bad you are so weak, it won't even be fun to kill you.

-You bastard!- The Fallen Angel threw his spear at Lucas, who extended his hand and said 'Gate of Babylon' releasing countless spears to block the light weapon. -So you awakened it already...

-Infact- Said Lucas slowly walking torwards the fallen angel with a psychotic smile. -And you shall be honoured that you will be killed by me!

Suddenly, Lucas's body started to transform as he turned into a lizard-like creature with one exceptionally long claw on each foot and razor-sharp teeth, that being his Velociraptor form.

Before the fallen angel could react, Lucas pounced against him, the raptor's claws coated in metal magic as he rips and tears through the fallen's flesh.

Little did they know a certain white haired rook girl had been watching this happen since she was passing nearby when the fallen angel revealed himself.

'I will have to tell this to buchou' Said the girl in her mind before leaving discretely.

Before leaving Lucas stores the Fallen Angel's corpse in his Dimensional Vault wondering if he could use the angelic power in it for something, he would have to check on the system later.

After that, Lucas went home, made some dinner and ate it while watching some old kaiju movie, before going to sleep.
