Hey there guys, I know you all aren't the biggest fan of the Bungo Stray Dogs sections of this fic, like I said I wanted this to be originally a Hero Academia DxD crossover, but then I decided to put another franchise to show the Red Dragon Emperor hero and those devils that the world isn't roses and breasts. I wont tell which one, because its coming soon.

This is the last Bungo Stray dog part for a while, after this we will be nonstop with DxD. We are getting near to Asia involvement. Enjoy.

Later on the Armed Detective Angecy.

The detectives were discussing about their latest fee, not just beating the Port Mafia from doing wrong doing again while Tanjiro was cleaning the agency.

''Well you guys should have been there. I mean I felt bad for the poor basted after a while.'' Said Dazai.

''I think I should have done more inspections on him.'' Said Akiko.

''shouldn't not encourage torture? I mean I know those people are bad, but torture isn't at all any good.'' Said Tanjiro.

''don't worry Tanjiro, he is a big boy. He can handle Akiko, the top ones those can get a bullet right in the chest and they won't feel a thing.'' Said Dazai.

Soon while Tanjiro was a bit confused on how tough the senior members of the Port Mafia were, guess who barges into the detective agency with regular clothes of a purple skirt, a purse and a white turtle neck?

''Tanjiro!'' Said Anya serious.

''Anya-sama!'' Said Tanjiro nervous.

''So this is your work?!'' Asked her seeing the agency.

''I know that you are still mad over yesterday. I am sorry but…

''Sorry! Do you know how worried I was yesterday! You could have been killed, I heard that those mafia people kill for sport.'' Said Anya.

''I told you that this rumor was around town.'' Said Ranpo to his coworkers.

''I guess it pay off.'' Said Akiko with a smirk.

The third year student still looked at Tanjiro with a glare while the Demon Slayer put the broom nearby, he felt he was in deep trouble.

''Anya-sama, I know this sounds a bit much, but I had no other option.'' Said Tanjiro.

''How come a janitor is in the line of duty and not you know in the safety on the office?" Asked Anya.

''Miss, if you please…'' Said Kunika trying to calm Anya but that didn't worked out.

''Shut up! I am talking to him!'' Said Anya making Kunikida seat down.

Tanjiro took a deep breath and gave the best explanation that he could about this situation.

''I am someone who doesn't like to see people hurt. No matter the trouble I will be there to protect those who are in need. I know what I did could be seen as wreckless, but I am fine, and I would do it.'' Said Tanjiro all serious and dedicated. He wanted to give an example as his feet while being on the Demon Slaying Corp, but he knew that a rule of the corp was not reveal much about it to the regular public. He told Anya because he trusted her.

The Detectives were surprised to see Tanjiro answer, he was so dedicated and humble. How come they have never seen before or heard about him. His ´´Sacred Gear´´ was still a mystery for them and they wanted to see where this would go.

''I knew this kid was gold.'' Thought Dazai.

Anya just took a deep breath and looked a bit tried.

''What am I going to do with you?" Asked her hugging Tanjiro.

Tanjiro blushed a little bit, his head was touching Anya breasts and he found that completely awkward.

''I am just happy that you´re ok. I know you´re strong, but these mafia people are crazy.'' Said Anya.

''Yes, I saw what they are like, but this won't stop me from protecting those who need.'' Said Tanjiro.

''I know.'' Said Anya.

''Uh tanjiro my boy. Aren't you going to present us to your friend?" Asked Dazai with a smirk.

''Oh sorry, Anya-sama these are the detectives that I work with. Everyone this is Anya Gotou, I live with her at the moment. That's Ranpo Edogawa, Akiko Yosano, Doppo Kunikida, Kenji Miyazawa, siblings Junishirou and Naomi Tanizaki, Kirako Haruno and last but not least….'' Said Tanjiro presenting each member of the place and leaving Dazai for last.

''I know who Osamu Dazai is.'' Said Anya.

''Oh! I am getting popular with Hing School girls? Tell me how do you know about me?" Asked Dazai trying to act all flirtatious but that wasn't working.

''You tried to commit numerous suicide attempts around my street!'' Said Anya mad as the detective either smirk or looked annoyed at that.

''In my defense those buildings aren't tall enough for me to break my neck. A few bruises at best.'' Said Dazai.

''DAZAI-SAN!'' Said Tanjiro in shock.

''I will deal with you later.'' Said Kunikida looking angry at Dazai.

''Great, I knew Tanjiro shouldn't be working in the same environment as this wacko!'' Said Anya.

Tanjiro looked a bit awkward, but he ended up kind liking this place. It reminded him of home in the Demon Slayer Corp, although as formal as the slayer, the detective were as impressive as the Demon Slayers or the Hashira.

''Let me guess, you like working here because you think they are really strong?" asked Anya with a confused look.

''Yes, I never seem them in action but I can sense power in all of them. I can tell they are really strong.'' Said Tanjiro making the detectives feel embarrassed.

''Oh tanjiro you are making us blush.'' Said Ranpo.

''Yes, we just try to work as hard as you city folk.'' Said Kenji.

''Such a naughty boy.'' Said Akiko with a smirk.

''See the boy has good taste. He sees only the best, like me.'' Said Dazai with a smirk.

''Like hell you are the best!'' Said Anya all angry at Dazai.

''Finally, someone that agrees with me!'' Said Kunikida.

Tanjiro laughed at that and noticed someone missing from the gathering, the white-haired boy Atushi.

''Hey, where is Atsuhi?'' Asked Tanjiro.

''He is still missing, but I think he will be back very soon.'' Said Dazai.

''I hope he is ok.'' Said Tanjiro.

''He is a tough guy, he can handle himself.'' Said Ranpo.

''Although he is still new.'' Said Kenji.

Anya just looked at the detectives and just bowed a little bit for them.

''Thank you all for looking after Tanjiro. He is trying to hard to fit around Kuoh, but I told him that he doesn't need to get a job at the moment.'' Said Anya.

''Well Miss Gotou, we do our best to protect the people of Kuoh from crime and stuff that the police cant handle.'' Said Dazai.

''What about the mafia?" Asked Anya.

''The mafia is getting more and more in action recently; we will try to handle their operation and put them down again.'' Said Kunikida.

''Yes, we need time and dedication. There has been…a lot of setbacks recently.'' Said Akiko.

''They might even be looking for Tanjiro. I mean…he bumped into their hideout.'' Said Dazai.

''I heard him mentioning that.'' Said Anya nervous.

''Do you think they will attack again?" Asked Tanjiro worried.

''As long they see that their profit might be in danger they will kill anyone who stand in their way.'' Said Dazai.

''Disgusting.'' Said Tanjiro angry at that. How could these people put money first instead of morality.

Anya just put a hand on Tanjiro shoulder and tried to calm him down. Everyone could tell that the boy was someone who believe in right and wrong, besides he was right, why people have powered given by God use them fro their own gains?

''Tanjiro is right, they are disgusting and overall maleficent. We are not going to stop until every single of them are in Jail. Understood?" Asked the boss of the precinct Yukichi coming into the room.

''Yes sir!'' Said the group.

Anya just smile at that. Those detectives might be odd, but they strike as brave and with a lot of power in their hands.

''I guess this is all for now, Tanjiro lets go home. I will make us dinner.'' Said Anya.

''don't want me to cook tonight?" Asked Tanjiro.

''No, you already worked today. Let me cook for you.'' Said Anya.

''Sure!'' Said Tanjiro.

''Bye everyone.'' Said Anya.

''Bye.'' Said Tanjiro waving.

''Bye.'' Said the detectives as they see the two leaving the office.

With Tanjiro and Anya.

''Sorry for coming unannounced. I wanted to make sure you´re ok, I couldn't stop thinking last night about that story you told me about the crazy lemon pyromaniac.'' Said Anya.

''Its ok Anya-sama, I know you are worried for me. You are my host, and I am your guest. I just don't want to be a burden to me.'' Said Tanjiro.

Anya pretty much stop in her tracks and grabbed Tanjiro wrists, that left the teen in confusion as the blonde talked to him about what he just said.

''Look! You are not a burden Tanjiro! You´re neve was one! You are one of the most amazing people I have ever meet in my life! I mean you saved my life from a weird spider! You helped me discover who I am! You are freaking Demon Slayer who saves people! Burden is something that you´re never going to be!'' Said Anya serious with a few tears in her eyes.

''Sorry, I retrieve my words.'' Said Tanjiro looking a bit down.

She then pulled out something out of her purse and gave him something. A little present.

''What is this?" Asked Tanjiro.

He opened the present and saw it was a phone.

''Is a present, you don't have a phone and I had this odl one laying around so why not give it to you.'' Said Anya.

''No, I can't accept this.'' Said Tanjiro.

Anya then grabbed Tanjiro hand and with her cheeks blushing just smile at him.

''I just thought…since you´re from an area with no technology this might be good for you. This way we can keep contact with each other, and I can know what is going on with you.'' Said her.

''Wow…I can do all this with just this thing?" Asked Tanjiro.

The teen soon clicked the phone and he felt like the world just exploded, he never saw something like this in his life.

''Its amazing! All these weird boxes and messages. What is all this?" Asked Tanjiro.

''You are going to need sometime to figure out how a phone works. Don't worry, I will be there to help you.'' Said Anya.

''Right! I can't wait to learn all about it.'' Said Tanjiro.

''remember your number, this one right here.'' Said her.

''I will remember with my life!'' Said Tanjiro with a smile.

Anya just smile as she and Tanjiro went home. Having him around was probably the best thing that happened to her in years.

With the detectives

The detectives went back to work, but Dazai as always wanting to skip work decided to talk about Tanjiro and Anya.

''Man talk about a true knockout. Tanjiro has been living with such a cutie, I am kind of jealous.' Said Dazai.

''You know she in underage.'' Said Kunikida.

''Yes, but when did that stopped most people?" Asked Dazai with a smirk.

''Well she has good taste. Tanjiro is the ideal material for a good boyfriend. I wouldn't mind having him around to…play doctor.'' Said Akiko all sinister.

''Yes Tanjiro is a sweet guy. She is really lucky to have him around.'' Said Kirako.

''Well he knows how to clean this place. This is for sure.'' Said Ranpo as the entire place laughs at that.

While the place was filling with laughs, Yukichi went to his office with a serious expression that Dazai caught right on.

''Where are you going boss? Doing something serious?" Asked Dazai.

''I am going to call Rias and Sona. With the Port Mafia acting up they should be informed.'' Said Yukichi all serious.

The detectives all nodded and soon they prepared to make some stuff for later. Two powerful girls would be coming towards their building later.

Later

At the Armed Detective angry.

Rias Gremory and Sona Sitri were in Yukichi office having some tea. They were by themselves; their queen haven't been accompanied them since this was a matter mostly for the two kings.

''So did you two heard about the current actions of the Port Mafia?" Asked Yukichi.

''Yes, they have been causing a lot of damage around the East part of town. Its getting out of hand.'' Said Sona.

''The port Mafia has been becoming stronger and stronger recently. I mean we could take them down, but there would be casualty of our sides for sure.'' Said Rias.

''I think you should let us handle them at the moment.'' Said Yukichi and the two nodded.

''What else is new?" Asked Rias.

''Apparently, they tried to cause some chaos around town. Did you two heard about the train incident and yesterday attack?" Asked Yukichi.

''I´m sorry, I have been busy helping out my new pawn.'' Said Rias.

''And I had paperwork to do.'' Said Sona.

''its ok, the train attack was stopped my new member of the agency. Although the yesterday incident wasn't stopped by a detective.'' Said Yukichi.

''What do you eman?" Asked Sona.

''Apperantly he was stopped by my new…janitor, who turns out to be strong as my detectives.'' Said Yukichi.

''Who´s he?" Asked Sona.

''His name is Tanjiro Kamado.'' Said Yukichi.

The information hit both Sona and Rias really hard. That was something incedible to hear, the fact that Tanjiro could handle a fight with a member of the Port Mafia and win, that just prove on how perfect he is.

''It appears that he keeps getting higher and higher.'' Said Rias with a smirk.

''Yes, he keeps appearing more and more in our lives.' Said Sona.

''I get the feeling that both of you know Kamado?" Asked Yukichi with a smile.

''Well…he has been getting a lot of attention lately. He is a new transfer student who has been showing off lots of potential.'' Said Rias with a smile and that caught Sona off guard.

''Rias are you thinking of recruiting Kamdo? You just got yourself a servant that took all of your pawn pieces.'' Said Sona.

''I don't know…maybe I will make him my knight or my rook. I am still looking out for him to impress me in person.'' Said Rias with a smile.

''Well, I also have my eyes on him. He is dedicated and polite, a great improvement of most boys in Kuoh Academy. If there is a peerage that he should be joining is mine.'' Said Sona.

The two were emitting a red and also a white aura of intensity. Yukichi decided to back off a little bitt before his whole exploded.

''Girls, not in my office please.'' Said Yukichi.

''Sorry, we just got a little off track because we both have stumble across Kamado-kun recently.'' Said Sona.

''Oh my its happening? Are we fighting to see who will be getting a new member?" Asked Rias with a smile.

''I don't know, you are already called the kid with the Booster Gear power to your peerage. I would like to call Kamado-kun to join me, but I know you Rias, you won't stop until you get what you want.' Said Sona with a smile.

''Its true, I still want to see Tanjiro be in action and if he is a powerful as Yukichi-san is telling us than he is worthy of a fight.'' Said Rias.

Sona just nod at that. She remember when half of her peerage failed to fight the Port Mafia, and then hearing a human defeating one of them sounded to good to be true.

''Ever since he appeared things have been changing a lot.'' Though Sona.

The two soon heard some reports about the Port Mafia and later returned home. This would be a discussion for much later with their peerage.

Later

Atushi had finally returned to the agency, after being missing for a while.

''So kid where have you been? We were worried sick you know.'' Said Dazai.

''Everyone this is Kyoka and she has a question for you all.'' Said her.

''I want to join the agency.'' Said the little girl.

So yes, Tanjiro and the detectives are in the move. Rias and Sona admit that they want to recruit Tanjiro, but they want to see him in action first, is like they want to make sure they are making this purchase. Well this might be interesting because after this Bungo will be much later, after this we will start the Asia arc. Hope you all are ready.
