Hey there, sorry for the two notes last time. I don't know why I was that angry about that story. I have some problems with that particular story and makes me dislike Izuku, because why is he having trouble with villains if he was able to taken down biblical monsters? You're telling me that asshole Stain is stronger than an High Class Angel villain? Fuck off. Sorry, going back to this one where Demon Slayer is the real thing. Now let's get back to this story.

Tanjiro saw Dazai on top of him and he just wondered why the hell did he just tried to jump off from a building.

''Why did you jump?'' Asked Tanjiro

''Oh I was trying to ened it.'' Said Dazai.

''End what?'' Asked Tanjiro.

''My life I wanted to commit suicide.'' Said Dazai all calm.

Tanjiro just look in shock as he gets back up and look at Dazai in shock.

''Why would do such a thing! Why throw your life away!?'' Asked Tanjiro.

''Because, I did a lot of things in my past that I wouldn't like to talk about it and I believe that killing myself alongside a pretty lady might be the right call for me.'' Said Dazai.

''You're a strange man.'' Said Tanjiro.

''Well thank you mister…'' Said Dazai wanting to hear a name.

''Tanjiro Kamado.''

''Well my dear Tanjiro, as a young person you should learn that everyone has a lot of baggage from their past and I am no different.'' Said Dazai.

''So that's it? You want to kill yourself to escape your past?! Why would you do that?'' Asked Tanjiro.

''Because if you knew what I did in my past…you would also try to kill me.'' Said Dazai all cold.

The teen couldn't help but feel a bad feeling, he couldn't help but remember some of the demons he faced before going to Kuoh, like some of them might have other thoughts before killing those people.

''Look you shouldn't just throw your life away, there is so much to offer and you need to be alive to experience everything.'' Said Tanjiro.

''But life is about making decisions, I did a lot on my day that would leave some people gasping.'' Said Dazai.

''I have also made some really big decision even being so young.'' Said Tanjiro.

''Did you…'' Said Dazai now leaning over Tanjiro.

The Demon Slayer know felt a bit nervous, but he also felt a dangerous aura, not demon level but still to be careful.

''How could you have made some big decisions if you're so young?'' Asked Dazai.

''You would be surprised what one night can do to a person.'' Said Tanjiro remembering the night that his family was killed, in one night his life completely changed.

The detective leaned back and just smiled at Tanjiro.

''I Guess I should apologize kid, my bad.'' Said Dazai.

''Well…I hope you don't try to kill yourself again Dazai-san.'' Said Tanjiro.

Dazai just laught at that. He was definitely going to try again sometime.

''Things aren't so easy here in Kuoh, I can tell you have seen some weird stuff.'' Said Dazai.

''Well…'' Said Tanjiro a bit nervous because he cant lie, but Dazai cut the chase.

''I know you were the one in the warehouse that night.'' Said Dazai.

Tanjiro just looked in shock at that.

''How do you know?'' Asked Tanjiro.

''You're new in town, plus you give a total mystical vibe. I can tell you were the one that ended that vicious creature. Nice job there.'' Said Dazai.

''You´re amazing, how did you figure out all that?'' Asked Tanjiro.

Then Dazai got a smirk and put his hand on his chin.

''Well I am glad that you asked that, because I am not just a suicidal lunatic, I am Dazai Osamu famous detective.''

''Wow so you're a detective!'' Said Tanjiro amazed at.

''that's right, I am very important person in Kuoh, well loved by all women, known for his hard work and dedication to the craft…'' Said Dazai but then his speech was cut short when a man with blonde hair and glasses went shouting at him.

''THERE YOU ARE DAZAI!'' Scream Kunikida.

Tanjiro saw the blonde man marching towards Dazai full of rage and the black-haired man lost his cool.

''Oh Kunikida!'' Said Dazai scared.

''Skipping work again! Do you know how behind schedule we are!'' Scream Kunikida.

''Oh come on, it was so boring down at the office. Surely one day of missing work isn't going to hurt anyone.'' Said Dazai.

''How about the 4 days worth of paper work at your desk, that should have you busy for the next 30 hours.'' Said Kunikida.

''Ew, you know I am allergic to paperwork.'' Said Dazai feeling sick.

''honestly! How can you slack off so much at your job!'' Said Kunikida pissed.

''Uh…is everything ok?'' Asked Tanjiro.

Kunikida turned to see a young boy with red hair, a scar in the forehead and earrings that represented the sun. He just wondered on what the hell Dazai did to this kid.

''Sorry for shouting young man, but my colleague need to learn the value of hard work.'' Said Kunikida holding dazai.

''Help me.'' Said Dazai pleading.

''No, mister its ok. It was a pleasure meeting Dazai-san and learning about his famous work as a detective.'' Said Tanjiro surprising Kunikida.

''Well isbt this nice, you're spreading lies to people.'' Said Kunikida to Dazai.

''hey the kid here is telling the true, he knows I am a great detective!'' Said Dazai.

Should he also know about all the complains related to you and your antics. By the way you got like 4 more just today.'' Said Kunikida

'You shouldn't say those lies in front of kids.'' Said Dazai.

''Its ok, I can sense his hearth is on the right place, but I would suggest he doesn't try it again.'' Said Tanjiro.

''What was he doing?'' Asked Kunikida.

''Trying to commit suicide.'' Said Tanjiro.

Kunikida then started to strangle Dazai, he was at the losing point.

''you again with this shit! How many times you have trying doing that just this month! Do you know how much this make us mad!"' Asked Kunikida.

''Oh sorry, it was a nice day and I thought it would be the perfect day to jump.'' Said Dazai.

Tanjiro felt odd while watching that scene, he thought it was best to leave and just try to forget all about it.

''Well…you two seem to have everything under control, I am going to leave and…'' Said Tanjiro but Dazai stop him.

''Wait kid do you need a job?'' Asked Dazai.

''Uh?'' Asked both Tanjiro and Kunikida confused.

''We have a job opening at our agency, we need a new janitor and we think you would be perfect for it.'' Said Dazai.

''What happened to the last one?'' Asked Tanjiro.

''He quit.'' Said Dazai.

''He got attacked by terrorist and was thrown out of the building.'' Said Kunikida.

Tanjiro didn't know if he should go on with these crazy people, but they weren't asking for documents or other things, plus it would be good to help Anya at the house.

''I know how to fight, I can handle some people.'' Said Tanjiro.

''You got the job!'' Said Dazai.

''What are you doing?!'' Asked Kunikida pissed.

Then Dazai went to Doppio ear and whisper at it.

'He might be a sacred gear user. Also, I have confirmation that he is the one that killed the Stray Devil the other that. By the way, I have a cross medallion and he hasn't been avoiding me so he can't be a devil.'' Said Dazai.

Kunikida couldn't help to admit this was a good argument. Killing a stray devil wasn't a easy task if you're a regular guy, so this kid must be special and he couldn't help but to feel some kind of power from him.

''Well mister…'' Said Kunikida and Tanjiro finish it off.

''Tanjiro Kamado''

''Come with us, we will show you the agency.''

The two older guided Tanjiro to the agency, the Demon Slayer was so caught up in the whole thing that he forgot about going back home to Anya.

Later

Once they arrive Tanjiro could only look in amazement at the huge building that the angcey was.

''This is the agency.'' Said Dazai.

''Wow it's amazing.'' Said Tanjiro.

''Yes, we are the ones that protect Kuoh from all the ''strange mysteries'' and other things and we all own to the director.'' Said Kunikida.

''Who is he?'' Asked Tanjiro

''His name is Yukichi Fukuzawa and you will soon meet him.'' Said Dazai.

''ok.'' Said Tanjiro

Once inside Tanjiro couldn't help but be amazed on how things worked in there, this was the first detective agency that he ever went inside.

''Wow, this is amazing.'' Said him.

''Yes, just wait to meet the gang.'' Said Dazai.

''Mister Dazai!'' Said a young man voice.

The group turned to see a young teen with white hair, running to check on the group.

''Oh great timing Atushi.'' Said Dazai

''Well you left me with your paperwork so I had no other option but to do most of it.'' Said Atsuhi all tired.

''Good job, I was busy talking with our new recruit in the building. Tanjiro meet Atushi Nakajima he is our newest detective, Atushi this is Tanjiro our new janitor and possibly new core member.'' Said Dazai.

''Nice to meet you.'' Said Tanjiro.

''it's a pleasure.'' Said Atushi.

While shaking Atushi hand Tanjiro couldn't help but sense something.

''Why does he smell like a cat?'' Thoguht him.

Soon the group went inside the office where there were a group of people all working and all with different clothes that Tanjiro have never seen before.

''Everyone this is Tanjiro Kamado, he will be our new janitor. Please let him be welcome and don't throw your stuff at him like we did with the last guy.'' Said Kunikda

''it's a pleasure to meet you all.'' Said Tanjiro.

The detectives already started to look at the new member of the building and by the looks they were already wondering what was his deal.

''Well we are keep getting new faces every day.'' Said a guy with a detective uniform.

''Oh he looks like a nice guy.'' Said a boy with jumpsuit and a straw hat.

''Big brother please don't spent time with him!'' Said a girl a middle school uniform.

''This would be a better option for me.'' Said a guy with white shirt and a red jacket on his waist.

''He looks interesting.'' Said a woman with a back shirt, black tie, white uniform and a butterfly haori.

''Come with me Tanjiro.'' Said Kunikida

''Ok.'' Said Tanjiro.

Tanjiro kept looking around at everyone staring at him and he just wondered if this was the right decision.

''Well let's start with me, my name is Dopio Kunikida and I am one of the most hard work members of the whole agency, lack any work and you will deal with me.''

''Oh come on, you need to know how loose up.'' Said Dazai.

''You already know Dazai, pretty much our slack off of the whole organization.'' Said Doppio.

''No! Please let me be cool in front of him.'' Said Dazai.

Tanjiro just sweat drop at that.

''moving on.'' Said Kunikida.

The group soon appear in front of a young man eating some snacks and wearing a typical detective uniform.

''This Ranpo Edogawa, he is our detective with the best deduction. If we have a trouble with a case, Ranpo can solve it in just a few minutes.''

''Nice to meet you.'' Said Tanjiro.

''Oh I can see a country boy just like Kenji. Tell me did your family work with some kind of mineral or natural based product?'' Asked Ranpo

''Yes, my family sells charcoal.'' Said Tanjiro.

''Charcoal, well I can tell because of that you have a good sense of smell.'' Said Ranpo.

''Amazing!'' Thought Tanjiro.

Then they went towards the desk of one of the female members of the office, the one wearing a butterfly Haori that made Tanjiro remember of Shinobu.

''This is Akkiko Yosano, she is also our medical assistance. Any injuries you go to her.'' Said Kunikida.

''Is a pleasure to meet you.'' Said Tanjiro offering a hand.

''The pleasure is mine.'' Said Akkiko.

Then the woman grabbed Tanjiro hand and started to touch his arm and inspecting his muscles.

''Strong muscles, I can tell you work really hard. I would love to see how they are on the inside.'' Said Akkiko making Tanjiro blush.

''Uh?'' Said Tanjiro worried.

''Oh would you like to have a nice time in my…emergency room. I promise I will put something to relax you.'' Said her with a smile and that made Tanjiro super nervous.

Tanjiro was then pulled away from her by Dazai.

''Stay away from this one kid. She a bit sadistic, but she is a good doctor.'' Said Dazai.

''Yes, but you don't want to get really messed up and have to deal with her operations.'' Said Atushi all nervous.

Then they went towards the boy with white shirt and orange hair.

''This is Junichiro Tanizaki, he is young but he is really good in researches and hacking.'' Said Kunikida.

''Hey there.'' Said Junichiro.

''Nice to meet you.''' Said Tanjiro.

''Hey big brother, aren't you going to introduce me!'' Asked the girl next to him.

''oh sorry, Tanjiro this is my little sister Naomi Tanizaki.'' Said him.

''Nice to meet you, I also have a little sister.'' Said Tanjiro

''Oh really, well I guess I am the office little sister and I am the cutest.'' Said Naomi.

''don't say that Naomi, you haven't even meet Tanjiro sister.'' Said Junchiro.

''Its ok, sorry big brother. You know I can't be mad at you.'' Said Naomi going very near Junchiro, in a very sexual way that made Tanjiro a bit nervous.

Doppio decided to take Tanjiro out of that scene so he doesn't have to see that creepy scene.

''don't think about it.'' Said Doppio.

''Ok.'' Said Tanjiro.

Tanjiro however couldn't help but he took a peek of the siblings, and the image of the girl trying to kiss her brother gave Tanjiro a better taste in his mouth.

''They seem….very close.'' Said Tanjiro.

''Don't go there.'' Said Kunikida.

''Ok who wants to meet Tanjiro!'' Said Dazai.

''Do me next!'' Said Kenji.

Tanjiro then saw the young boy with blonde hair and the whole country outfit.

''This is Kenji Miyazawa, don't let the cute look be a distraction, he is one of our most valuable members.'' Said Kunikida.

''Nice to meet you.'' Said Kenji.

''it's a pleasure.'' Said Tanjiro.

Tanjiro then went to shake hands with Kenji, if wasn't for the two years of hard work training to be a demon slayers he would have been probably have his hand crushed by Kenji strength.

''Wow what a handshake.'' Said Tanjiro.

''Yes, my sacred Gear allows me to have this power.'' Said Kenji.

''Your what?" Asked Tanjiro.

''Moving on…'' Said Dazai taking Tanjiro aside.

''Who is left?" Asked Kunikida.

''Uh…I guess the director.'' Siad Dazai.

The man with the ponytail just nod at that and then decided to let the boy meet their boss.

''Tanjiro you will meet now our boss, please be on your best behavior.'' Said Kunikida.

''Ok.'' Said Tanjiro.

The group soon arrived at office where a man wearing a kimono was talking with a girl with glasses.

''Oh Kunikida and Dazai…who is this young man?" Asked the man in kimono.

''We got a new addition to the team director.'' Said Dazai.

''Who you might be?" Asked the director.

''My name is Tanjiro Kamado, it's a pleasure meeting you sir.'' Said Tanjiro bowing.

''Polite and determined.'' Said the director.

''And such lovely earrings.'' Said the girl.

''Tanjiro this is our director, mister Yukichi Fukuzawa and next to him is one of our secretaries Kirako Haruno.'' Said Kunikida.

''it's a pleasure to meet you young man.'' Said Yukichi.

''Do you go to Kuoh Academy?" Asked Kirako.

'Yes, I am a second year.'' Said Tanjiro.

''Oh good. Have you ever meet some friends of ours there? Their name are Rias Gremory and Souna Sitri.'' Said Yukichi.

''I meet Souna-chan and her whole club, they are all really nice people. However, I haven't meet Rias-san I am sorry.'' Said Tanjiro.

The director took note of that, so this boy doesn't know the true about the girls and why would Dazai and Kunikida want him to join the force?

''Do you have any experiences as a janitor?" Asked Yukichi.

''No, but I was the older of 5 siblings so I know how to clean a mess.'' Said Tanjiro.

The old man just laugh at that and could tell that this kid has a good hearth.

''So you are ok working with detectives?" Asked Yukichi.

''Well…I never been near detectives before, so I think I will manage ok.'' Said Tanjiro.

''I think you were born to be with us.'' Said Dazai.

''Yes, I can tell you´re super excited.'' Said Kunikida annoyed at that.

''Well since you are willing to work with us you got the job.'' Said Yukichi.

''Really! Thanks.'' Said Tanjiro.

''You got to be here tomorrow at morning and then we will talk about wages and schedule.'' Said Yukichi.

''Great, I can't wait to tell Anya-sama this.'' Said Tanjiro.

Tanjiro then realized that he was gone for almost an hour and a half and Anya must have been worried about him, so he decided to hurry.

''Oh no! I didn't told Anya-sama that I would be late, she must be worried about me.'' Said Tanjiro.

''Go home to your lady, we will see you tomorrow.'' Said Dazai.

''Thank you all and see you tomorrow.'' Said Tanjiro leaving the agency.

The detectives all see Tanjiro leaving the office at full speed and of course starting gossiping about thim.

''So this kid is something.'' Said Ranpo.

''He has a weird look even for the people of Kuoh.'' Said Junchiro with a laugh.

''I have to say he is not bad looking, I might even say quite handsome.'' Said Akiko with a dark smile.

''I don't like where this is going.'' Said Ranpo worried for Tanjiro.

''Those earing are really unique; I mean why that whole thing about the Rising Sun?" Asked Naomi.

''Yes, he seems a bit off.'' Said Kirako.

''What is the big reason for him being here?" Asked Atushi.

''He was at the scene of the crime a few days ago. This was before you join with us Atushi.'' Said Dazai.

The others detectives looked surprised at that, Atushi was a bit surprised of what was happening.

''Wait, do you mean…'' Asked Akiko confused.

''Yes, he killed that Stray Devil that day. Not Sona or Rias groups, he alone killed and I don't think he is an exorcist or member with the church.'' Said Dazai.

The members of the Armed Detective Agency were really surprised by that, more so was Yukichi who was chuckling at that.

''Interesting.'' Said him.

With Tanjiro.

Tanjiro ran up to Anya home and he finally arrived with the grocery, making the blonde girl a little relief.

''Anya-sama I am back!'' Said him catching his breath.

''Tanjiro-kun what happened! I was worried sick about you.'' Said her hugging Tanjiro.

'I ended up meeting with an weird guy on the way back.'' Said Tanjiro.

''What weird guy?" Asked Anya still near Tanjiro.

''His name is Dazai Osuma and he is a super detective.'' Said Tanjiro.

The girl stopped the hug and looked a bit odd at Tanjiro.

''Wait a minute. Guy with bandages, dark hair and a brwn coat?'' Asked her.

''You know him?" Asked him.

''He is a weirdo that he's been trying to kill himself near our area, why he is not in jail is a miracle.'' Said her.

Tanjiro just has a sweat drop on his forehead, so Dazai really tried to kill himself multiple times.

'So anything else you might like to say?" Asked Anya.

''I got a job! I am going to help in this house.'' Said Tanjiro.

''You didn't need to do that Tanjiro-kun! You´re my guest!'' Said her.

''No, I think I will be here for a while so I want to help as much as I can. I don't like to waste your money, so I will use my paychecks to pay the costs that I caused while I was here.'' Said Tanjiro all serious.

Anya was now blushing at this. A man who was getting a job just to make sure he wasn't wasting her things, well her father pays for water, electricity and etc. so this wouldn't matter, but the fact that Tanjiro did the extra effort it really said something.

''Well, I am glad you did that but next time you need to talk to me first.'' Said her.

''I promise to never do these kind of decision before talking with you.'' Said him.

''Good.'' Said her.

Tanjiro and Anya soon went to have dinner and still talking about the events of today.

''Well we surely had a big day. You got a job; I discovered that I am a witch. Things really weird keep happening to us.' Said her.

''Good things Anya-sama.'' Said Tanjiro.

''Yes Tanjiro, good things.'' Said her.

The two soon went to have dinner and they went to sleep. Anya would soon start having her own witch training while Tanjiro will start his job with the Detective Agency.

The next day

Tanjiro was now at the Agency and full Janitor uniform. Kunikida was there to give him the orders of the day.

''Ok, I am ready for the job.'' Said Tanjiro.

''Well I am glad to see someone excited about doing his job.'' Said Kunikida while glaring at Dazai.

''What is that all about?" Asked Dazai.

''First clean Ranpo area, its already full of wraps and other things.'' Said Kunikida.

'Oh this doesn't sound too bad.'' Said Tanjiro.

Once he arrived at Ranpo area he was shocked to see full of garbage and all kind of crap, it looked like Inosuke side of the room back at the mansion.

''What!'' Said Tanjiro in shock.

''Is something isn't.'' Said Dazai.

Then something started to move around the pile of garbage, they soon saw it was Ranpo himself.

''Oh hi guys, is morning already?" Asked Ranpo.

''Yes Ranpo, it is.'' Said Kunikida.

''Hey Tanjiro, I guess you will be full today.'' Said Ranpo with a smile.

Later

Tanjiro took 1 hour to clean all of Ranpo crap, there was wraps and other snacks all over the place. It was a miracle that the place didn't have any roaches or rats.

''This is it! The last one.''' Said Tanjiro finishing the clean the area, that was so clean that you could eat in the floor.

The detectives just smile at that, but Dazai kept a close eye on him.

''You are really a special boy Tanjiro.'' Thought him.

So yes, we have Tanjiro meeting the Bungo Stray Dogs. He meet the Port Mafia so he should meet the detectives. Next chapter is going to be an interesting fight and I hope you all have a good time, sorry for the broken English and bad grammar but you should be used by now.
