Hey there guys, we are going a bit off the main track. Now we are about to introduce a new character to the story, an OC and I was planning her for a while. Lets see what you all think of her and her story. Let's see how Tanjiro deal with this.

At some area on the Underworld

The Area of the Succubus

In a place called Liltith Castle

This was the reign of the Underworld dominated primarily by the Succubus and Incubus race. So you could imagined that was pretty much the red light district of the realm. There were more brothels and strip clubs than actual hotels, it was a paradise for perverts or sex driven people. However that are was controlled by a family, called Lilith named after the first woman of Adam who would later become the first succubus in history. Through time the woman had numerous children but one kept consistent and they became the ruler of the whole area of these creatures.

The castle was big and majestic, something out of a European picture. There a young woman with long black hair, blue eyes and big chests (AN: Size near Akeno) was waking up from her sleep, as she gets out of the bed naked she was going to put on her clothes for the day until the staff of the castle appear.

"Young Mistress Lara, your mother is calling.'' Said a succubus with a raveling maiden dress.

"Uh?'' Asked the young succubus named Lara.

"Your mother is calling you.'' Said the maid.

"Thank you Margaret, I will be there in a few minutes.'' Said Lara as she prepared.

A few minutes later

The succubus soon putted her clothes for the day as she went towards a throne room, in the main one was a woman with a beautiful face, golden hair that could be mistaken as pure gold and a revealing outfit showing off most of her chest (AN: Size just like Venelana).

"Mother.'' Said Lara to her mother the queen of the Succubus,

"Rise my youngest.'' Said the queen of the Succubus Evaline.

The woman looked at her child with a smile as it was time for her daughter go and fulfill her task.

"You shall be going to the human world around this noon. After that I want to see constant updates on your ways into making your harem of boys. You're a succubus with Lilith blood in your veins, you shall bring as much man as you please.'' Said Evaline.

"Understood mother, I won't let the family down.'' Said Lara.

"Since you are so eager and very full of energy I picked a special place for you.'' Said Evaline.

"What is the location?'' Asked Lara.

"Your destination will be…Kuoh, Japan.'' Said Evaline.

The location surprised Lara as she heard of that city due to who lived there.

"Wait. Isnt this the same city where the little sisters of both Lucifer and Leviathan both reside? Said Lara.

"Yes.'' Said Evaline.

"And you think it's a good idea send me to the same place as girls with power of destruction and Water Serpents?'' Asked Lara worried.

"They're both dumbs. Rias Gremory won that territory due to Nepotism and Sona Sitri barely operates anything there. Just watch your steps and you will be fine.'' Said Evaline.

The information kind made sense, Lara only heard good feats about Rias Gremory but since her brother was the Lucifer of the Underworld, he might be playing around wihth the news and ideas that have been spreading around his sister.

"I see.'' Said Lara.

"Your sisters are all with their harems and they are at their full extent of their powers. I wish that you achieve the same results as them.'' Said Evaline.

Lara had 6 sisters (Soniy, Levanda, Wanda, Anabelle, Livia and Sally) were all powerful succubus on their own rights. All of them with a large amount of men that were like their pets, only there to make their sexual desires get fulfil and get stronger. The more sexual tendencies a succubus has the more powerful they are.

"You will be on your own but I made sure to give you a nice house in Kuoh.'' Said Evaline.

"Thank you mother.'' Said Lara.

"I want by the end of this year you have a harem of at least 100 men under you . Last year your sister Anabelle managed to get back 300 men under her thumb.'' Said Evaline.

"To be fair she was in America and that's kind easy up there.'' Said Lara with a smile.

"Agreed.'' Said Evaline with a smile.

"Yes, at least it wasn't Wanda trying to make those incubus join her.'' Said Lara.

"Don't be afraid to try new things. I am sure you will found humans and other species to fall in love with you, but remember they are only for sexual pleasure. If a man fall in love with you remember that is never about true love.'' Said Evaline.

The young Succubus heard that and just nodded in response.

"I won't fall in love mother. This is nothing but a bunch of bullshit to sell to girls. I will get my harem and I will get my name craved in history as one of the strongest succubus.'' Said Lara.

The queen just smiles as she prepared for the departure of the young girl.

A few days later

Lara was with the Kuoh Academy Uniform and was already settled in her new house. She now had to just go to the school and make that place her own. With her curvature and nice body, she knew she would get a nice amount of boys to be all over her.

"Ok, today is the day my conquering of lust start!'' Said Lara excited.

The girl looked at her uniform and just wonder if that was by design or was the actual thing.

"I don't know if the people in that place are actual perverts or not. It's a very short skirt for someone of not legal age.'' Said her looking herself in the mirror.

The reality was that Lara was a bit scared of starting out her life as a sucubuss, she wasn't super social and easy to talk like her sisters but she felt that she need it to start out with a boy first this way she could get a hang of it on how to do with others.

"I need a lacky first. Anything would do.'' Thought her walking in the streets.

A few blocks away

Tanjiro was ready to leave for school with Anya, both with their uniforms down and ready to go.

"Tanjiro-kun I am sorry, but I need to stay here to deal with some mold problems. I already called school letting them know I will miss a few classes.''' Said Anya.

"Oh sure, I understand.'' Said Tanjiro.

'I am sorry that you will have to walk alone to school.'' Said Anya.

"Don't worry, I will be fine and I will be waiting for you at lunch.''' Said Tanjiro.

"Alright, but make sure you don't cause any scenes.'' Said Anya.

"Understood.'' Said Tanjiro.

"Have a good day Tanjiro-kun!'' Said the Fallen Angel girls now maiden of the Gotou Household.

The demon slayer gave a bow as he went towards school as always.

As he walks he thinks about the current events of the past few days.

"Things are getting really weird. First, I stopped some Fallen Angel from doing harm, then three of them move to Anya-san house and they like to sleep naked with me. Asia-chan has a different presence than before and yet I have no clue on how to get back home.'' Thought Tanjiro trying to wrap his head around all that.

The demon slayer was more worried about his sister and if she was ok far away from him. When he was trying with Urokodaki at least Nezuko was at sleep at his cabin for almost 2 years, now he was worried if she would be walking near the sun or did something.

"I just hope Nezuko is ok. Well she with Zenitsu and Inosuke and while I would get crazy if I let them alone with her I am sure they….'' Thought Tanjiro as he thinsk he bumps into someone.

BAM

That someone was Lara.

"Ouch!'' Said her hitting the ground as her panties of blue colors were being show.

"Oh my God, I am so sorry!'' Said Tanjiro bowing and apologizing a lot.

"No problem this….'' Said Lara turning her head.

The succubus soon saw who bumped into her. A cute boy with a nice scar, beautiful hair, good abs and a nice face.

"I think I found my first.'' Thoguht her.

"Are you ok?'' Asked Tanjiro worried.

"Yes dear! Thanks for being worried about me.'' Said Lara going over Tanjiro.

The succubus was making sure her breast touched Tanjiro arm, while she was filling his muscles Tanjiro was blushing like mad.

"Not bad! I mean he does look like works out a lot.'' Thought Lara.

"I am sorry, let me help you.'' Said Tanjiro.

"No worries dear, I can get up just as fine.'' Said her.

"I am Tanjiro Kamado, nice to meet you.''

"Oh how polite. My name is Lara Livistar.''

"Nice to meet you Lara-san are you new to Kuoh?'' Asked Tanjiro.

"Yes, but I just arrived and I am trying to get directions to my new school. Could you give me some help?'' Asked her.

"Sure.'' Said Tanjiro.

The succubus just smile as she takes vantage of the nice boy and she felt she would conquer the hearts and minds of the boys of Kuoh in no time.

"At this point I shall have at least 10 in one week. Just wait and see mother.'' Thoguht Lara.

Tanjiro however kept sensing a weird smell from her and it was bogging his mind.

"Her smell is like Rias-chan but a bit different. Also, with a mix of sweat. Its wrong to think these things.'' Thought Tanjiro.

At Kuoh Academy

The two soon arrived and Tanjiro gave her instructions on where to go to register.

"So I just need to meet up with the Student Council President to give my schedule?' ' Asked her.

"Yes, the teachers are always busy so Sona-sama is the one that does this sort of things.'' Said Tanjiro.

Meanwhile

Rias and Sona were discussing the current events of the past few days. They're playing chess as they talk.

"How does a school have so many problems in less than a semester?'' Asked Sona.

"Most school don't have to deal with the same of supernatural as us.'' Said Rias with a smile.

'I agree, by the way congratulations on your new Bishop. Incredible Sacred Gear she possess.'' Said Sona.

"She is going to adapt fine to her new environment. Get this apparently she meet Tanjiro before having this whole deal with the Fallen Angels.'' Said Rias.

"Tanjiro is a very kind individual, I am not surprised that he has become so popular.'' Said Sona.

The red-haired devil saw the little smile on her friend face and that got her to think.

"Sona you are not thinking of adding Tanjiro in your peerage?'' Asked Rias.

"What if I am?'' Asked Sona with a smile.

"Not fair! I was planning on adding him!'' Said Rias with puff checks.

"You already got a person with a powerful sacred gear and now a girl with a healing power. Let me get someone too!'' Said Sona with some points.

"I know but…I feel something special with Tanjiro. Every time I talk to him I feel so warm.'' Said Rias being honest.

"Yes, a lot of girls says he can cause flame through their hearts. Just ask my knight.'' Said Sona.

The two just looked at each other with game faces, now they were going to see who Tanjiro was going to choose first.

"Let's see who he ends up choosing.'' Said Rias.

"Agreed, checkmate.'' Said Sona.

As they finish their game Sona took a sip of tea and leaves the room.

"I need to go back to my duties I have to talk to a new transfer student.'' Said Sona.

"Good luck.'' Said Rias.

"Thank you and…lets see who gets Tanjiro-kun first.'' Said Sona.

"Sure.'' Said Rias with a determined smile.

The idea of getting Tanjiro was to add in their peerage. While he doesn't possess a Sacred Gear he already had a ton of qualities. Determination, leadership, honest, hard work and charm. These were all the things you would want on a servant.

Rias however admired those things on Tanjiro and maybe…even more.

At the Student Council

Sona arrived at her office where her VP was waiting for her.

"Kaicho our new student has arrived and has been waiting for your presence for about 10 minutes.'' Said Tsubaki.

"Sorry for my tardiness.'' Said Sona to the new student which was Lara.

"No problem, I know as the President you must be one busy girl.'' Said Lara.

Neither Sona or Tsubaki could get a trace that Lara was a succubus, the girl was smart and made sure to make her ability pretty hidden so neither Pure Blood Devil nor the Queen could sense it. She had to play safe in Kuoh or she would be grass. However, at the moment her mind target was Tanjiro.

Later

Tanjiro was sitting on his desk listening to the main top of the day, not knowing as he was being watched.

Outside someone was watching Tanjiro. A man with a half-done beard, red trench coat and a sleazy attitude.

"So this is the kid.'' Thought Azezel with a smirk as he saw the one that was responsible to take inn all the missing Fallen Angels

So yes, we have a new character on the name of Lara and her design is pretty much like a stereotypical anime girl with black hair. I almost wanted her to have giant horns, but since this is DxD I decided to cut those outs.

I wanted to introduce Lara to be a future love interest, and try my hand on OC love ones. After the last chapter of Hero Academia DxD I feel that Tanjiro needs more girls. I am sorry, I don't know why I have such animosity towards that series, but I don't know why the Izuku rubs me the wrong way in there. Like he is so far removed from Izuku and more like Issei with less perverted views, not to mention that all the girls are 100 times more simps that they are in the canon of DxD and not even Harem Izuku have this level of simping. Like I read that whole pole dance and I just think why am I am cheering for you?. Like he is still going to bitch and moan when he loses to Shigaraki which is in my mind the only one that can defeat him, like unless the villain from the first movie has a powerful Sacred Gear that turns him into Magneto or Muscular is the descendant of an Ogre I don't know what else can he do. Like I am pretty much seeing Izuku defeating Loki with more tacts and strength than issei but then he will lose to Mirio, that I am never going to understand.

I am not giving Tanjiro like a pole dance with 30 girls, because that's not him. I want him to have a harem but they will be for pure love and not because he is the main character.

Also, after re reading what they did with Kendo I felt this little thing. Even Succubus and descendants from Asmodeus cant corrupt Tanjiro heart to be lustful due to him being so pure.

Sorry for this little rant, I know its pathetic. I hope you all have a good time.
