Hey there, I am so motivated to write this fanfic so much. I don't know why its because I want to show the world so cute Rias and Tanjiro would be. Also the fact that Demon Slayer is now dominating the world, I mean what kind of anime has its premiere episode in various cinemas worldwide. Take that! Well lets see what is going on.

Tanjiro wakes up as early as usual and does his morning routine. He makes sure to not make any noise because he doesn't want to wake up Anya, the girl has been so kind to him so he wants to make sure he isn't any bother.

''I guess I can make breakfast this time.'' Said him.

Once he was in the kitchen Tanjiro made some bacon, eggs and toasts. He knew how to cook because he usually helped his mom in the kitchen to feed his siblings. He then heard someone coming in and he felt it was Anya.

''Good morning an…'' Said Tanjiro with a smile and he soon saw how his hostess was looking.

The girl looked like she barely slept last night. She had her eyes full of dark circles, her hair was such a mess, and her pajama were all crumble.

''Anya-sama!'' Said Tanjiro.

''Oh hi Tanjiro.'' Said her.

''Do you need to go to a hospital?" Asked Tanjiro.

''Oh no, its nothing serious. I just…didn't get much sleep last night.'' Said her.

''What happened?" Asked Tanjiro.

Anya didn't know what to say. She didn't wanted to say ´´things started to float and I freaked out´´, she would sound like a crazy person.

''Nothing, let me just take a shower and change.'' Said her.

''But…'' Said Tanjiro wanting to help, but Anya wasn't having any of that.

''Nothing happened!'' Said her.

''Are you sure?" Asked her.

''Well Tanjiro-kun I feel like you don't know much about a modern girl. So if we say there is nothing wrong than it means there is nothing wrong.'' Said her going to grab a mug of coffee.

Tanjiro felt there was something wrong, her smell even indicated that.

''She is barely slept at all last night. She was sweeting and even crying.'' Thought him worried.

''Look, I just need a cold shower, some pills and then I will be good in no shape. I will sleep early today that's all.'' Said her.

''Oh ok.'' Said Tanjiro still not sure.

Tanjiro made a plate for Anya and soon the two had breakfast and went off to school.

Later

Tanjiro was taking notes on the subject of his class. However, he couldn't help to think on what Anya was going through. He wished he could know what was happening to her.

''I hope she isn't sick or something.'' Thought him worried.

The demon slayer felt bad because he couldn't do anything to help out at the moment.

''What could have made her be in this mood?' Thought him.

With Anya

The girl was barely listening to what kind of lesson her class was giving. All night she was having an existential crisis, almost like she was begging that of that she presence was a lied and she was dreaming.

''I am normal! I am normal! I am normal! I am normal!'' Thought her repeating that in her head over and over again.

The girl was just shaking and people around her were nervous and wondering if she was ok.

On Lunch

Anya and Tanjiro were eating on the cafeteria. The boy could see that she was still shaking and looking like she saw something that could scare her off, he wonder what could have caused such a thing.

''Are you ok?" Asked him one more time.

''Yes! Why do you keep thinking I am not fine?" Asked Anya.

''You been messing with your peas so much that they look like a mashed potato.'' Said Tanjiro looking on the food.

''Tanjiro…I am having personal problems, things that a boy wouldn't know. Don't you have sisters?'' Asked Anya trying to remember.

''Oh yes, Nezuko is my only sibling that is still alive.'' Said Tanjiro with a sad tone.

The girl forgot that Tanjiro also had his family killed and by the sound of his voice that night it was kind of recent compared to Anya who lost her mom and sister when she was young.

''Crap, I shouldn't have done that! What should I say?" Thought her.

''Anya-sama what are you thinking?" Asked Tanjiro.

''Well after class you and I are going to have our swimming training. Don't you said you wanted to have that?" Asked her.

''Oh yes, I am happy that you remembered.'' Said Tanjiro.

''For you I won't forget a thing.'' Said Anya.

''Understood.'' Said Tanjiro happy.

The two continue to eat while some people were looking at them. Even wondering if they were a couple.

Sona was eating next to her peerage and looking with interest in Tanjiro.

''They seen to be very close.' Thoguht her.

There was also some perverts who were looking at Tanjiro in pure hate.

''How the hell did he got such a hottie to himself?" Thoguht the pervert trio in pure anger over Tanjiro. It was bad enough that he was getting attention of many girls, but now he was so close to such a hot blonde with big breasts.

After class

Anya was wearing a school swimsuit uniform, one that could definitely show off her curves and make her chest look big. It was a bit uncomfortable, but she was used to people starting at her.

''Tanjiro-kun are you ready?" Asked her.

''Yes.'' Said Tanjiro coming.

The boy soon appeared wearing a school trunks for swimming. What caught Anya attention even more was his ripped boy and scars. She didn't know what Tanjiro did before, all she knew it was his was a mountain boy and it showed that he was constantly working out.

''Uh something wrong with Anya-sama? Am I unpleasant? Asked Tanjiro feeling ashamed.

''No! No! No! You look great!'' Said her with a smile and her check red.

Then the two soon get into the water, Anya was grabbing Tanjiro arm as he floats in the pool.

''Ok let's start with some basic stuff.'' Said her.

The two started to swim, Tanjiro knew how to swim regular because of the river near his house. However, he never did in a big pool, this way it could be good for when Nezuko turn back he could show her how to swim like this.

''Like this?" Asked him now swimming with no problem.

''Yes! Wow you´re a fast learned.'' Said her.

Tanjiro smiled at that. This was a bit hard, but compared to what he had to endure with Urokodaki this was a piece of cake.

''I am swimming! In a big pool!'' Said Tanjiro swimming in free style.

''Great job Tanjiro-kun!'' Said Anya happy keeping pace with him.

Tanjiro and Anya kept swimming like there was no limit, of course the girl was faster than him, but with more times in here Tanjiro could really show his strength in the water.

''This is really great!'' Said Tanjiro all happy.

''Yes, swimming is the best. Hey wanna do a race?" Asked Anya.

''Ok!'' Said him.

The two swim in great speed and made sure to not cause a ton of mess in the pool area.

''I won.'' Said Anya all happy.

''Oh you´re so fast Anya-sama.'' Said Tanjiro.

''I do this for the last 3 years; I make sure to be at peek so I can make Kuoh be in the finals.'' Said Anya.

The two just kept floating with no problem and Tanjiro felt this was very relaxing as they just stay there in the water.

''This is great.'' Said him.

''Never been to a pool before?" Asked her.

''No, I only swim in rivers.'' Said him.

''Wow Tanjiro-kun you´re really a country boy.'' Said her.

''Yes, me and my family just went to the city to do shopping or sell some things. We usually stoyed mostly in the mountains.'' Said Tanjiro.

''What did you do?" Asked her.

''We were charcoal salesman. We have done that for generation.'' Said him.

''Oh so you were…'' Said Anya a bit nervous but Tanjiro finishes for her.

''Poor, yes but we were happy. We felt like we were grateful for what we had. We had a roof, food and we didn't ask for much.'' Said Tanjiro.

The girl just smile at that. Tanjiro was such an honest person. Maybe was this way why he didn't took advantage of people, he was raised in such a simple way that it was surprising that he didn't wanted more.

''You could have so much more.'' Said Anya.

''Its ok, I know what I am doing. Maybe I will change some things in my future, but right…I have a simple goal in mind.'' Said him referring to revert Nezuko back to human.

The girl felt that whatever Tanjiro goal was it was very personal and shouldn't be triggered or mocked, so she decided to let it pass.

''Come on its getting late.'' Said her.

''Sure.'' Said him.

While getting out of the pool, Anya went first, and she even stood near the stairs to help Tanjiro out. However, while going up Tanjiro slipped.

''Oops!'' Said Tanjiro loosing balance.

Then Tanjiro felt like he need it to grab something to stop his fall. He grabbed something and it was Anya swimsuit, he managed to grab on the holds but his hand grabbing the swimsuit was now showing off Anya breasts and that shocked both of them.

''Uh?" Said her in shokc.

''AAAAAAH!'' Said Tanjiro in shock so much that he went to the water.

Splash

Once he was out Tanjiro apologized over 1000 times.

''I´m sorry!'' Said Tanjiro.

''Its ok, its was an accident.'' Said Anya all red and looking to the other side.

The two felt this was an awkward moment and decided to let it pass, but Tanjiro couldn't let this moment out of his mind. He felt so ashamed that he let something like this happen.

Later

Tanjiro wanted to make it up for what happened this afternoon. So when he was in Anya house, he was trying to be productive all the ways possible.

''Clean, I must clean.'' Said Tanjiro cleaning the leaving room.

''Tanjiro-kun I told you, that was an accident. You don't need to clean my place.'' Said her.

''But I am your guest and I saw…your breast. I need to make it for such an indecent scene.'' Said Tanjiro.

Anya just took a deep breath; this guy was hard to convince on some things.

''Ok, but don't overwork.'' Said her.

''understood.'' Said him.

Then after cleaning the living room, Tanjiro decided to clean the rest of the house.

''Let me do some cleaning around the house too.'' Said him.

''no! I don't want you working as a maid, you are my guest!'' Said her.

''Please, let me at least fix my room.'' Said him.

''Ok, but just your room.'' Said her.

The teen went to his room to see what else he could clean, while Anya was having some hard time in keeping him in check.

''Why is he like this?!'' Thoguht her.

On his room

Tanjiro was cleaning his closet again, he wanted to make sure no more dirt or dust was in there.

''I need to make it up!'' Thoguht him.

However, while cleaning Tanjiro found something hiding behind some of junk in the closet. It was a small envelop.

''Uh?" Asked him looking at that.

The envelope was unopen and it had a piece of paper inside.

''Anya-sama, I found in this in the closet.'' Said Tanjiro.

''A letter? In the same place you found the book?" Asked her.

''Yes.'' Said him

The girl grabbed that and open in a hurry. Once open she saw something that shocked her.

''What is wrong?" Asked him.

''It's my mom handwriting.'' Said her

The girl started to read the letter and she was shocked to see her mom writing after so long.

´´´Anya, Erza, if you two are reading this than it means that it's time to tell you two the truth. If you noticed some weird things happening to you two is not because you two are going crazy, it is because your powers have awakened. This may sound weird, but we come from a long line of Wiccan in other words witches. I am one myself and a so you´re two too. I hope that I am still alive to teach you two when the time is right, if I have passed keep reading the book. It has all the answers that you need. Don't be scared my daughters, witchcraft is in your blood ever since you two were born and you shall embrace it. Please, keep calm and don't share this secret with everyone. May the goddesses look after you two, with love mom.´´

The girl looked at that letter in shock. Not only that answered what happened last night, but so many other mysterious things that happened in her life. It was all like everything made sense and she felt shocked to know the truth.

''Anya-sama what is wrong?" Asked Tanjiro.

''I am a witch.'' Said her all shocked.

The boy looked in surprised to hear that and so as Anya as she look in shock at her own hands.

So yes, Anya is a witch. I wanted her to be something non-human, so I decided on witch because outside of Le Fay witches aren't used that much in DxD. Also, I am not much of a reader of the graphic novel, so I don't know how much Le Fay plays in the story.

Also, thank God I found out about Witch Watch. Here is the thing, I didn't know about Witch Watch when I was planning this stuff. Now I got a whole bag of ideas.

Thank you all for reading this chapter. See you all later.
