Hey there, lets go back to the world of Demon Slayer mixed with My Hero. Some of you are really liking how I am handling this world and how things are working around here. I started to have so much fun in here. I wont be doing things like the arcs of Demon slayer until a certain point. I want to focus on My Hero first then we will see what we can do. Lets now get things going.

A few months later

Izuku has been staying in the Demon Slayer Corp for 3 months now. He has definitely started to gain muscle mass, but of course the training under Shinazugawa has giving him scars on his chest, arm and a little bit on the face. Nothing major, but he was still working harder than he has ever worked before.

''Ok, time to pass the circuit again. Ready brat?' Asked Sanemi at the start of the hill.

''Yes master!'' Said Izuku.

The teen soon rushed and saw the traps coming all the way. After failing to pass this maze of trap over and over again Izuku managed to get down where they were going to appear and what kind of trap was going to be launched. For example, he just barely avoided the log toss coming at his right.

''Woah!"' Said Izuku dodging the log.

Then he remember this was the spot where the covered hole was being hidden. He soon took a big jumped as the hole didn't got him this time.

''Ah!'' Said him happy that he dodged that one too.

Izuku then dodged the darts, snakes, rocks and all the other things that Sanemi had prepared for him to endure training. He could finally end this circuit with no problem.

''I think I am going to do it! I am going to finally…'' Thought him all happy.

But then a trap was released near the end, a rope in the floor that caught his feet and then made him being hanged near a tree upside down.

''Argh!'' Said Izuku in shock.

Sanemi shook his head in disappointment, so close.

''a trap for animals and it was kind visible! How could I not see that!'' Thought Izuku pissed.

The older man went there and took Izuku out and once he felled to the floor and continued to give him orders.

''Do it again!'' Said him.

''Yes sensei!'' Said Izuku.

The wind hashira looked annoyed, the kid was here for three months and had barely even started the breathing training. If he doesn't do that then his chances of learning the techniques are down.

Later that day.

With the Hashiras.

The higher ranking members of the Demon Slaying corps were all together and discussing Izuku progress.

''So how is Izuku-kun doing?" Asked Shinobu.

''He is doing alright.'' Said Sanemi.

''When do you think he should start having breathing training?" Asked Giyuu.

''If the pace continues, I would say 4 or 5 months.'' Said Sanemi.

''This is either good or bad.'' Said Uzui.

''don't get me wrong, I would expect the brat to quit at least 8 times by now, but he keeps getting back up.'' Said Sanemi.

''Yes, he has a great dedication. I guess its his spirit to help others.'' Said Gyomei.

''Or is the part of him that wants to prove those bastard wrongs.'' Said Iguro.

''Its flamboyant! I cant wait to see a demon slayer being a hero!'' Said Uzui excited.

''Well he cant say he is a demon slayer. My guess he will say he is a samurai hero, people will find this cute.' Said Mitsuri.

''The kid has come a long way. He is not like your little brother Shinazugawa or Shinobu little siter but he is someone that is still going.'' Said Muichiro.

Then the former Hashira Kanae Kocho arrived and that got the currents one condused.

''Where is the master?' Asked Sanemi worried.

''The master will stay in bed tonight; he will move the meeting to tomorrow. He apologizes for any inconvenience.'' Said Kanae.

''No problem.'' Said Shinobu.

'We need to focus on how to make that kid improve his training. If he can't pass the circuit at this moment who knows if he will be ready for the final selection.'' Said Uzui.

''Like hell we can make any miracles. If that was the case than the demons would all be extinct.'' Said Iguro.

''I just wish we could do more for him.'' Said Mitsuri.

''I would like to change subject for a moment. How is Izuku mom doing with all this?" Asked Gyomei.

''The kid calls her at least 4 times a day. I keep hearing a lot of crying and saying how much she loves him, over and over again.'' Said Sanemi.

''It must be good to still have a parent who loves you deeply.'' Said Mitsuri with a sad smile. Most of the Hashira families were killed by demons and the Master was the only family that they had.

''Yes.'' Said most of them.

''Well if that the case I need to go, I need to prepare new traps for the kid.'' Said Sanemi leaving.

With Kagaya and Amane.

Currently the leader of the Demon Slayer corps was going as Mr U to Inko Midoriya, this way he could make her feel a lot calm and make sure Izuku wasn't in any sort of danger.

''Oh Mister U, I saw some of Izuku pictures today. What kind of training is he having? Those scars on my baby are making my hearth go all around.'' Said Inko nervous.

''don't worry miss Inko, those scars aren't anything to be worried about. Its show how much dedication and hard work your son has put in his training over the last few months, you should be proud of that.'' Said Kagaya.

''Oh that's great, my baby has been working so hard. I never expected him to get in such shape.'' Said Inko.

''Your son is a great hero in the making. I vow that he won't be in any danger while under my watch.'' Said Kagaya.

''Yes, but what about any villains attack or anyone that want to harm you?" Asked Inko.

''I am secured, my family and children are all protected by the best security in the world. Don't worry, your son wont be in any danger while he is under my name.'' Said Kagaya.

''Oh thank the heavens. I don't know how to thank you Mr. U.'' Said Inko.

''I do my best; I am also a parent and I want what is good for my kids to purse their dreams. Unfortunately we can't be in some situations, but I want Izuku to successes and show the world that you can be a hero even without a quirk.'' Said Kagaya.

''Thank yo so much Mr. u. I don't know if I am ever going to repay you.'' Said Inko with a river of tears.

''We will discuss this in the future. Now go rest miss Inko, have a good night.'' Said Kagaya.

''Thank you and have a good night also.'' Said her.

Upon finishing the call, Kagaya wife Amane couldn't help but look a bit surprised at Inko tone at the end of the line. She was hearing the talk since she was holding the phone for her husband.

''She sounds like hse has been crying a lot.'' Said Amane.

''She worries about her child. You and me would also act like that if it was any of our children.'' Said Kagaya.

''I agree.'' Said Amane with a small smile.

''Izuku is training in an great pace. He still needs to pass the circuit and then do the breathing training. I wonder how long this will take?'' Said Kagaya

''Outside of the final selection how it's going to be with the UA test? They will question everything about you.'' Said Amane.

''don't worry, I already have a plan for that.'' Said Kagaya.

Amane embraced the hand of her husband and just put her head on his shoulder.

''I know dear, I know you will be taking care of everything.'' Said Amane.

The Next day

With Izuku

The teen was trying to do some pushups, but he was so sore from yesterday training that it was kind hard to do even a set.

''Urgh! Today is not my day.'' Said him.

The green haired teen was pretty much desperately trying to breath a good amount of oxygen, because he couldn't breathe right during training.

''How am I going to keep it up?!'' Thoguht Izuku.

''Psst.'' Said someone.

The teen looked confused to see who it was calling for his attention and then out of nowhere Kyojuro Rengoku appeared.

''Hi Kid!'' Said Rengoku.

''Rengoku-sama!'' Said Izuku in shock.

''What are you doing in the floor?" Asked Rengoku.

''I can't do more pushups. My arms are not responding.'' Said Izuku.

''If you breath in a good pace and do it faster than you won't feel so much sore in your muscles.'' Said Rengoku.

The teen was surprised about that and he really didn't thought about this idea.

''Is he giving me advice?'' Thoguht Izuku.

''Well I have to go. See you later.'' Said Rengoku leaving.

''But wait…'' Said Izuku but the flame hashira had already left.

The flame Hashira was gone and Izuku decided to do the style that he passed, miraculously it worked and he finished his set.

''What was that all about?" Asked Izuku.

A few days later.

Izuku was on the Butterfly mansion getting treated. Shinobu was expecting his arm while applying medicine.

''So how is training so far?' Asked her.

''Well Shinobu-san, its rough but I getting used in the end. I just wish it didn't hurt a lot.'' Said him.

''If you want a little tip, try do some quick jogs near the forest. There is a lot of open space so you can be faster when practicing, this is how I ended up getting faster.'' Said Shinobu.

The teen blinked in surprised by that tip, he didn't thought about that while avoiding all those traps.

''Really! Wow thanks Shinobu-san, I didn't imagine to using this idea.'' Said Izuku.

''Yes , training can give a new perspective on things. Now how about you try some of my new medicine based on rotten roots?" Asked Shinobu.

''Uh?" Asked Izuku nervous.

The next day

Izuku was doing what Shinobu told him, but it was clearly that he wasn't getting any faster. He had a nice pace, but nothing that would scream fastest man alive. Then a silver blur appear near him.

''Faster kid!'' Said Tengen Uzui.

''Woah Uzui-san, careful there!'' Said Izuku scared.

''If you don't focus on your target then how are you going to get faster? Huh?! Answer me kid.'' Said Uzui.

The teen agreed with him and as soon uzui left Izuku tried to run as fast as he could with a goal in mind.

Later

Izuku was done taking a bath and was going to his room. He wanted to relax but apparently that wanst going to happen.

''You need to do some breathing training every 2 hours.'' Said Iguro appearing at a tree branch.

''Aaah! Iguro-san!'' Said Izuku in shock.

''If you tell anyone that we talk I am going to let the others snakes, have you for lunch.'' Said him.

''Uh what!'' Said Izuku in shock.

''don't make me repeat myself.'' Said Iguro pissed as he was now gone.

The teen was confused, but then he remembered what he was told. Breathing training was Important, but he wasn't ready for that. However, maybe it was an pre class or something.

''What is with them?" Thoguht Izuku confused.

The next day.

Izuku was outside meditating, trying to get the perfect balance of his body so he could do some breathing training. However, while he was focused that was soon broken by a cheerful voice.

''Oh Izuku-kun!"' Said Mitsuri all cherfull as always.

''Mitsuri-san.'' Said Izuku surprised to see the love hashira.

''Are you meditating?" Asked Mitsuri.

''Yes, I need to keep my body in balance I am going to breath more.'' Said Izuku.

''Oh yes, I used to have a problem when I was doing that.'' Said her.

''Really?" Asked Izuku.

''If you need to keep in great balance find some rocks to keep your body in perfect symmetry. It worked for me when I was training, it should work on you.'' Said Mitsuri.

''Oh this sounds perfect.'' Said Izuku with a smile.

''Miss Mitsuri your meal is ready.'' Said a random Corp member.

''Oh ok, by Izuku-kun.'' Said her waving goodbye.

The teen waved back at the woman and then saw over 7 carts full of food being pushed towards the pink haired woman room.

''Why all that food?" Asked Izuku confused.

The next day

Izuku was now training sword swings again and he wanted to make sure his hits were certain.

''Keep a clear view of your surroundings.'' Said Giyuu appearing behind Izuku.

''Uh Giyu-sama.'' Said Izuku confused.

''If you don't k now your surroundings than the demon will attack you at a new angle. We lost a lot of people because of this error, don't mess this up.'' Said Giyuu leaving.

Izuku just look at his surroundings and wonder what else he might learn.

''Why are the hashira helping me?" Thought Izuku.

Later

Izuku was walking down the hall of he headquarters when suddenly Muichiro appeared and walked past him very quickly.

''When breathing just think of that, nothing else.'' Said him very quick as he went off.

''Uh what Muichiro-san…'' Said Izuku confused.

The wind student turned around to see the Mist ahshira was already gone.

''How does he do that?' Asked Izuku.

Later

Izuku was lifting weights and trying his best to not crack, however someone could sense that Izuku was at the point of passing out.

''Oh child, please don't push your limits this far.'' Said the stone Hashira Gymoei appearing out of the blue.

''Gyomei-sama!'' Said Izuku in shock.

''I can hear you heartbeats going at increasing pace. Take some minutes off, have some tea and onigiris. If your body doesn't have nutrients than it might as well be begging for rest.'' Said Gymoei.

The teen just listen to Gyomei and agreed with him. He was super tired and he decided to take a break.

''Thank you Gyomei-sama, I was a bit scared to go on a break, but I don't have to be afraid of that.'' Said Izuku.

''You´re welcome child.'' Said him with a smile.

The teen had his break and it really helped out. He felt like he was back in the game and fully charged.

Later

''Oh Izuku, here is your dinner. I hope you enjoy.'' Said Kanae putting his meal on his room.

''Miss Kanae…do you have any advice?" Asked Izuku.

''Uh…if you keep your breathing and mind at the same time you might be able to achieve what you are looking for.'' Said Kanae as she leaves the room.

Izuku heard that and upon listing to what the Hashiras have been saying to him over the past few days he realized that he has finally understood what he should do.

''I got it!'' Said him.

A few days later.

Izuku was now at the start of the circuit, he was ready this time.

''I got this!'' Said him.

The teen managed to avoid every tap, every attack, every surprise throw at him. He felt a bit sense of accomplishment once he managed to survive every single thing being thrown at him. After months of hard work, he has done it, he finished the entire circuit.

''I did it!'' Said Izuku.

Sanemi was just quiet watching this, he wasn't impressed because Izuku did what he was told.

''Ok kid, you passed this part. Time for the next one, this time I won't be present as much however I will be coming to see your breathing.'' Said Sanemi.

''Uh what do you mean?" Asked Izuku confused as he try to catch his breath

''Its time for the big one.'' Said Sanemi.

''What?" Asked Izuku.

''The most difficult and mind bothering test in all of your training.'' Said Sanemi.

''What is it!'' Said Izuku nervous.

''Come with me.'' Said him.

A few miles away.

The two were now on a foggy area of the headquarters. It was kind hard to see what was around them, all Izuku could see was trees.

''What is all this?" Asked him.

''See that rock? '' Asked Sanemi pointing at the rock.

Izuku saw the rock, it got to be at leas 2 meters tall and it felt like one of those old-style Japanese traditions since it had a robe tied there.

''If you destroy that rock, you will be able to take the final selection. If you don't than we will send you back home. You have 6 months to do it.'' Said Sanemi

Izuku looked in shock at this. 6 months was a long time, but something told him that this wasn't going to be an easy task.

Here we go, we got to the rock scene. Once we get passed that we go first to the UA test than the final selection. This is how I am visualizing everything. I hope you all are liking and sorry if the writing isn't that great.

Here is something to let you all know. All For One doesn't know about the Demons. I know since he is very old he would but he just think hey are legends. The monsters only come at night and he think they are just some people with cannibal quirk.

I know due to his nature he should have known, but Muzan has been around for a thousands years so he knows how to hide better and how to operate in the shadows better.

Now enjoy this silly thing here.

Omake

Because I´ve been binge watching Critical Role and Matt Mercer is the Leader of the Demon Slayer Corps, so I decided to do this stupid thing here.

The hashira were all gathered for their weekly gathering. What cause such a gathering? Play Dungeons and Dragon. It was something that they thought it would be silly, but they ended up enjoying the story and the adventure. The players were: Shinobu an cleric, Tomioka a bard, Sanemi a barbarian, Rengoku a ranger, Uzui a paladin, Mitsuri a sorcerer, Obanai a rogue, Tokito a fighter and Gyomei a monk.

''Alright players, lets start the campaign.'' Said Shinobu.

''Yes!'' Said the Hashira.

Soon Ubuyashiki arrived being acompined by Amane.

''Wiat a minute…Withouth your dungeon master?" Asked him.

''No master!'' Said the Hashiras.

''Good, lets start the game.'' Said him.

''Yes!'' Said them.

This was fun and I am not that much deep into dungeons and dragons, but Critical Role is awesome!
