Chapter 6 New Morning

Eri for the first time she could remember slept peacefully. It was strange and forigne but she liked it. She was safe.

Though that didn't stop her from panicking when she awoke in an unfamiliar room. She calmed down when the memories of the previous night came to her. She didn't know what to do. They were nice to her but the Yakuza would come looking for her. Chisaki would come and then the nice people would die because of her. Eri then began to wrap herself in the sheets wanting to return to her peaceful slumber.

"Are you still tired I can come back later." Eri then saw Tomo looking over her with a big smile on her face. Eri didn't know what to say she wanted to say sorry. She didn't want anyone else to die because of her. That's when another part of her decided to talk.

"Gggrrroowwwl"

"Well it sure sounds like someone is ready for breakfast." said Tomo as she picked Eri up. Eri tensed up a little but soon relaxed to Tomo's gentle touch. "How do pancakes sound?"

"Whats a Pancake?"

"Super yummy food you're going to love."

They soon made their way towards the living room where they found Yushiro watching the Izuku train in the courtyard. "Good morning Tomo, Eri." said Yushiro without taking his eyes off Izuku. "Don't forget to watch your stance. You're going to lose power if you don't get a good stance for the Breath of the earth techniques."

"Yes Sensei. Morning." said Izuku not looking as well."

"Morning." said Tomo

"Morning." said Eri in a small voice. "Can he see us?"

"Hhmm. No he's most likely using his other senses to tell where we are." said Tomo as they watched Izuku for a minute. "Would you like to stay and watch." Eri was a little surprised she wasn't used to getting asked what she wanted. She was honestly afraid of answering but nodded. "Okay then. You can stay here with master Yushiro while I go make breakfast." she said as she put Eri down right next to Yushiro before going to the kitchen.

Eri sat there quietly watching as Izuku ran through several drills as Yushiro gave him some advice ever now and then. Eri was still scared to say anything or to ask anything she just stared at Izuku and glanced at Yushiro every minute or so.

"I can't give you a proper answer if you don't ask a question." Yushiro smiled at Eri. "I will try to answer any questions you have to the best of my ability."

"What are you going to do to me?"

"Well with your permission I would like to help you and give you a permanent fix to your quirk."

"You can help me? You can take the curse away?"

"Yes I can help you. I'm very familiar with quirks and I know a way to turn your curse into a gift that you can use in anyway you so desire, but I would like your blessing to do so." He said with sensarity.

Eri almost couldn't believe it. It was almost too good to be true. "Why? Why would you help me."

"Eri I know I might not look like it but I've been around for a very long time. During that time I've seen people happy and I've seen people suffer. I have suffered as well so has Tomo and Izuku. An old friend of mine showed me that people can be happy that they can become better no matter what life has thrown at you you can still turn it around. He gave me hope after I lost the only love of my life until the day he died, he still showed me the hope of life. I want to help you because I want to and because I have the power to do so. I want to give you a helping hand like my friends did for me."

Eri began to think over everything Yushiro just said not really understanding it. She didn't really know what to think. A helping hand was so strange to her and Yushiro could tell. The way she was squirming he could tell she had barely known what kindness is.

"I know this might be too much for you but believe me when I say we will help you we will protect you." Eri looked at Yushiro and saw no lies. It calmed her enough to feel peace. She felt like she could trust these people. She knew now they wouldn't treat her like Overhaul did. They sat in silence for a little while. "Do you have any other questions?"

"Umm what is he doing?"

"Izuku is going through some of his breathing styles. He's trying to get better at the ones he's not good at."

"Breathing Styles?"

"Breathing Styles are different ways to breathe. Depending on how you use the breathing style changes the way you fight and the fighting style used. It was the main form of combat used by the Demon Slayers."

"What's a Demon Slayer?"

"Heroes who fought a secret battle against monsters that threatened many people. They had made many sacrifices to do so. They won in the end but sense many had no idea what they were doing they became lost to time. I spent a good part of my life gathering and preserving their knowledge and even learning many of their techniques. I thought it was terrible that they would be forgotten so I made it a goal that they would be remembered."

"So can you use the breathing as well."

"Somewhat, unfortunately I'm not exactly built for them. Though I made sure I understood it enough to pass it on to others. Like Izuku. I think he was born for it."

"Is he strong enough to beat the bad man." Eri said afraid of what would happen when he shows up.

"By himself I'm not sure. I've never met this Overhaul but he won't be alone. I've already contacted several people this morning. The government already has their eyes out for him and if I ask for back up they will give it."

"Government. Thats the people in charge of Japan." asked Eri she didn't know exactly what it was but she knew Overhaul didn't like them. "You work for them?"

"No, I work with them. You see years ago as technology advanced it became harder and harder to hide and I didn't want any of my hard work to go to waste. I thought it was high time I introduced myself to the government after I showed them the truth of the Demon Slayers and the benefits of my advanced knowledge in science and technology. They agreed to make a deal for me. They help me keep the knowledge of old safe and help keep me hidden from others and I would help them on certain projects that I would agree upon. I learned that I would need something to occupy my time before I went crazy with boredom. Though when quirks first started to appear things got real busy. It's been that way for a while, eventually I became acquainted with quite a few people of power around the world that are willing to help me and in turn I've helped them one way or another."

Eri stayed quiet after that mainly because she had no idea how to take the information. Even Yushiro had to admit that was quite a bit of information for someone so young to take, but he wanted to be honest with her so he could build a bond of trust. Even though she may not be able to understand everything he was saying she could at least tell he wasn't hiding was about to say something to make it easier to understand when Izuku finished his drills.

"Morning Eri did you sleep well." he asked. Eri nodded as her stomach growled. "Sounds like someone wants breakfast. Is Tomo making food?"

"I believe so." Said Yushiro checking the time. "Though I have to say she is taking a bit longer than usual."

"Breakfast is ready." yelled Tomo from the dining room.

"Well speak of the devil. Come, children let's get some food." said Yushiro as he took Eri's hand and walked her to the dining room. Only to stop as he entered.

"What's wrong sensei- WHOA" said Izuku as he saw it.

"Tomo what is this?"

"Its breakfast Master." said Tomo wiping the sweat from her forehead.

"This is enough for an army." he said pointing to the mountain of food on the table. "Or Godzilla."

Izuku could only stare at it. "There's pancakes, waffles, omelets, bacon and eggs. So much more. I don't even know if we can eat all of this."

"I'm sorry. I wanted Eri's first breakfast to be special so I just started cooking and kinda didn't stop."

"Tomo" said Yushiro pinching the bridge of his nose as he was lost for words.

"Oh come now sensei at least we now have enough here to find something Eri would like. Right Eri. Eri?"

.munch.

The three look over to see Eri at the corner of the table eating an apple from the fruit bowl.

"It would seem that our new friends hunger has gotten to her." Said Yushiro "Come on. This food isn't going to eat itself."

~o~

To say Overhaul was pisst would be an understatement. First He lost Eri when on ehis men dropped her when he apparently saw some sort of demon girl in pink. Still trying to figure out what that was. The brat known as Demon Slayer took Eri and with little effort beat several of his men who were now arrested. Overhaul tried to bribe the officers to let them go when the government stepped in. That was a very unpleasant surprise and before he knew it this morning three of the Yakuza branches were hit. Not by the heroes or the cops but a special ops unit from the frickin military. Why the hell would the military be after him? They barely do anything domestic nowadays there only really called in for international conflicts or a supervillain goes apocalyptic. One of them even tried to jump him while he was out looking for Eri. He even needed to dirty his hand with one of their feathly disgusting blood. Why the hell were they going after him now? They weren't even using warrants or even trying to arrest them. It was like they were ordered to kill on sight. None of this made any goddamn sense to him. He hasn't even told others about his overall plans, he hasn't even perfected the formula, yet they were treating him like a global terrorist.

Chisaki couldn't help but wonder. He was currently deep in the depth of the yakuza's lair currently cleaning his mask and washing his hands as they still felt dirty. When his right hand Chronos came in. "Overhaul one of the guys who was able to get away from those military guys has returned."

Overhaul kept his eyes on his cleaning. "He wasn't followed was he?"

Chronos then put a letter down on the table. "NO, he was actually saved by another group of villains."

Overhaul knew Chronos long enough to know he wasn't joking. He put his rag down and picked up the letter and began to read it. "The League of Villains? I've never heard of them."

"Neither have I. They seem to be new and it appears they know a thing or two about this Demon Slayer kid and what to do something about it."

Overhaul put the letter down. "So they want our help and it seems they want to talk to us as well."

"Would you like to give them the usual response." meaning to go and tell them to shove it.

Chisaki thought for a moment before coming to a decision. "No. Right now we aren't in a good position. We refused before because we didn't want to get absorbed or taken over. Though without Eri we can't make more quirk removal bullets and with the military hunting us. It might benefit us from making a few friends, even get a few new recruits to refill our ranks."

"Make sense so you want me to tell them will help them out."

"Yes but tell them I want info on that Demon Slayer brat first." Said Overhaul as he thought about the brat that has put the brakes on his operations. His anger began to reach a tipping point. "I want to find that brat and turn him into a pool of blood over and over again till I get bored."

~o~

Izuku was filling great as he walked out of the bathroom just getting done with taking a shower. Even though Yushiro's home was an old Japanese style house it was quite advanced with a lab and medical wing. It even had the basic household needs but those were definitely better than anything other people had. If he didn't know Yushiro was an immortal who got bored easily he would never believe he built all of this stuff himself.

Though he did feel slightly bloated. Tomo made a lot of food and with so many options Izuku tried a little bit of everything. Tomo is a great cook, there was no way he could deny that. Usually he would finish his plate but this is the first time he could remember where they had left overs.

Izuku went into the living room to see Yushiro and Tomo sitting on the poarch in the sun with the wooden box between them. He knew they would be there apparently when Yushiro was able to stand in the sun again after not being able to see for over two hundred years. He spent a whole year just watching the sun. He still loved sitting outside in the sun.

"Sensei, Tomo."

"Izuku how was the shower."

Izuku patted his stomach "Great. Though I think I can wait a bit for dinner."

Tomo scratched her head and apologized.

"You know you don't need to make so much all the time. I don't need to eat food to live." said Yushiro as he was reading something on his phone.

"I'll always make food for you master."

"Wait, don't you get hunger sensei."

"Not really. To be honest if it wasn't for others telling me to eat I would forget for days. All I need is to take my medicine and with the recent improvements I've made I only need to take it once a year. Though of course I do eat if others are offering, the rare craving or the foods too good to pass up."

Tomo puffed her chest with pride. "That's why I always provide the best so you'll keep coming back for more."

Izuku couldn't help but chuckle a little. "Hey where's Eri?"

Tomo reached into the box moving the blanket revealing Eri sleeping at the bottom. "She fell asleep real quick after breakfast. After I put the leftovers away she had already climbed into the box and fell asleep, I just bought her the blanket."

They couldn't help but think how cute she was. "She's so peaceful when she sleeps. Though why would she go to the box to go to sleep? We have plenty of beds."

"It probably brings her comfort." said Yushiro "When she ran into the spirit of Nezuko she suggested to hide in a box. It was most likely the only reason she wasn't found and was able to stay safe. Some part of her believes the box is a safe place."

This reminded Izuku how he met Eri and what horrors she's lived through. "Sensei what's going to happen now with Eri."

Yushiro closed his eyes as he thought everything that needed to be done to help this girl. "She's going to need surgery. Even though she's in one piece the villain overhaul had used his quirk to destroy and recreate her over and over again. Though clearly it has had an effect on her quirk in more ways than one. Her quirk not only went out of control but also tried to heal her. Even when Overhaul used his quirk to repair her, her quirk was also trying to repair itself. Overtime it has moved and distorted several parts of her internal organs which lead to her quirk to go crazy even more, not to mention the drugs used to increase her blood cell count. It may not be a problem now but as her body grows it could cause many medical issues as she gets older, so the first thing she needs is basic surgery to correct the organs and after that we can tackle her quirk. Until then I'll simply redirect her quirk to keep it under control."

"Well that shouldn't be too hard." said Tomo "We both have several years of medical practice we can easily handle her surgery to help her out."

"I'm afraid it isn't that simple. The reason we were going to focus on fixing her body first is so that I can safely redirect her quirk because it clearly can affect her physically like self healing and the effects on the horn. This way we can not only get rid of the build up of her quirk but also hasten her healing process. In short we will be working with her quirk and can you tell me what would happen if we mixed her quirk and yours together."

Tomo was silent for a moment as she looked at her hands and then to the sleeping girl. "That would be a disaster."

"I'm sorry Tomo I know you want to help her especially since you know somewhat of what she's going through, but your quirks are too risky together. One wrong move and we could create a bigger problem than the one we were already dealing with."

Izuku put a comforting hand on Tomo's shoulder. "So what do you need if there's anything I can do just say the word."

Yushiro smiled. "Don't worry Izuku you'll have plenty to do. There will be numerous things we'll need to make this work and I'm going to need you to see some people personally. The doctors needed to make sure this surgery goes off without any problems are a bit stubborn unless you grab them in person they won't come."

Tomo raised an eyebrow at Yushiro's words. "Stubborn doctors? Wait a minute. You don't mean those maniacs do you."

"Tomo they maybe have some egos but.."

"Egos that's what you're going with."

"Okay their crazy."

Tomo simply just gave him a deadpan stare.
"Okay their batshit crazy but you can't deny their skill."

Izuku sat there partly confused on who they were talking about and happy Eri was still peacefully sleeping through this bit of madness. "Um who exactly are we talking about here."

"I'm only guessing here" said Tomo "But I think master is thinking of calling a doctor called the dissector, another one that has a flaming serpent, one that is obsessed with a perfect body, an old snail lady and an old mountain witch that has a talking tanuki, and one thats called the dissector."

"You already said the dissector and the mountain witch has a reindeer not a tanuki. One thing I've learned over the years is that the most talented people in the world have the s The sooner we get that done, the sooner I can personally fix her quirk so the Yakuza will never use her again."

Tomo seemed to accept his reasoning but it just gave Izuku more questions. "How exactly do you know these people, sensei?"

"Around five years ago during there was a villain attack with a quirk that allowed them to create a super plague. Though luckily he was an idiot and gave us time to get several doctors together to find a cure. I met them there and yes, several doctors came from more than questionable backgrounds. They also know I'm hundreds of years old."

"WHAT" they both yelled in surprise.

"SSSSHHHHH" as Yushiro pointed to Eri. "The villain may have been an idiot but he found out about the doctors and attacked the hospital where we were. During the attack several of the other doctors ran away but a few of them stayed and fought. During the attack I may have lost a few limbs so when I got backup. Well lets just say there were a few questions they wanted answered of course I lied about most of it. They accepted I was one of the oldest people on the planet and one of the first people to get a quirk that healed me and stunted my growth. So not only are they good but they know who I am so they'll help."

"Master with all do respect they're crazy. Isn't there anyone better for the job?" asked Tomo not wanted people so unhinged near Eri.

"Don't worry I'll make sure they stay in check. The government owes me so they'll pay them off and just in case I can call a few people in for security if needed. " Said Yushiro also thinking of what else they'll need. "Though the equipment here is good they will need an upgrade to make sure we can monitor Eri's condition and the amount of energy her quirk outputs. Looks like I'll be calling Shields a lot sooner than expected."

"Wait Shields as in David Shields All MIght FIrst sidekick." said Izuku shaking trying to control the hero nerd deep inside of him. He was failing.

"Yes he was here yesterday before you brought Eri home. Wanted my help on a project but he refused to tell me what it exactly is. Something to do with enhancing quirks but that's as much he was willing to tell me. That and a personal request to check what I assume is a patient. I guess I'll need to give him a call."

Yushiro began to make sure he had Shields number as a contact before reassuring Izuku that he could get David Shields autograph. That's when his phone began to ring.

"Hello…. Yes… Really already. I gave you that info this morning. I see …. I guess that makes sense. There's no need to apologize, I understand how this could have been a political problem. Thank You, please keep me up to date." said Yushiro as he hung up the phone and smiled at the sleeping child. "The government used the info I gave them and took out several Yakuza bases. Apparently they've been paying attention to the rumors of a quirk erasing bullet and have had their eyes on the Yakuza for quite some time. When I told them about Eri they jumped on the chance."

Izuku was shocked and somewhat confused. "What I thought they would only get involved if a villain was going to somehow destroy the country entirely."

Surprisingly Tomo decided to answer that question. "Izuku they were working on mass producing a bullet that could destroy quirks can you imagine what would happen to the country that has relied on quirks for years if that bullet got out. It would end the country."

Izuku played the scenario in his head realizing how much damage it would do to society. "That would be bad."

Yushiro nodded "Indeed but that aside we have work to do. So we're first going to need-" He stopped as they heard a cute yawn as they looked to see Eri waking up in the box. "Oh good morning again, Eri."

Eri stretch a little before rubbing the sleep out of her eyes. "What happened? What's going on?"

Tomo couldn't help but smile at the cuteness of the girl. "You fell asleep right after breakfast."

"I think food coma would be more accurate."

~o~

David Shield was currently laying down in his hotel room just staring at the ceiling in his own failure. Weeks ago the scientist was ecstatic to learn not only the legendary immortal doctor was real but also willing to talk to him. He had come all the way to Japan to ask for his help. He wanted his help into finding a way to increase the power of a quirk but the immortal said no even when David said it was for a hero. He had also figured out that the Immortal Yushiro had somehow unlocked the quirk to the new hero Demon Slayer but the second he asked about it Yushiro was silent and David could tell he was making Yushiro angry. He then informed him that he's willing to help with projects that will help society as a whole and will not help any personal project without being given proper information. Even though this doctor was a secret himself he couldn't reveal his friend's condition. In the end he had gotten nothing.

He was now just waiting for his plane later tonight to take him back to I Island and back to his daughter Melissa who has been calling him over and over again. David had already deduced his assistant had told her that something had happened.

There goes his phone again. Time to finally tell her he failed and would be on his way home. He picked up the phone without looking at it. "Hello Melissa I'm sorr-"

"This isn't Melissa"

David immediately shot out of the bed. "Mister Yushiro!"

"Hello Mr. Shield" said Yushiro

"What ….Why are you calling me?"

"As you know I don't get involved with projects when there are secrets involved, but I need help to be more precise, I need some special medical equipment to help a friend. So in turn helping me with my problem I will take a look at your quirk project and your patients."

"Really you're willing to help." said David a little bit in disbelief. "Wait patients?"
"Yes. You are trying to make a quirk enhancement device for a Hero whose injured right. I already have an idea who it is, but I won't push just have their medical records with you when we meet again. You can redact their names if you want. As for the second one you'll need to either bring them with you. When you began asking me how I unlocked Izuku's quirk that was for someone else wasn't it. Someone who's having problems with their quirk correct."

"Uhh Yes. The quirk enhancement device is for a hero and the questions about the boys quirk was for someone who has problems with their quirk." David never mentioned anything about Melissa being quirkless. He had done some research and saw that Izuku was medically stated to be quirkless. He had hoped that Yushiro could somehow give Melissa a quirk he knew how much she had looked up to All Might and how much she wanted to be a Hero. Everytime she came up with some new invention she always mentioned, she wanted to see in action helping heroes but he knew she wanted to use them herself.

He knew he could have mentioned her to Yushiro but was afraid sense he knew how well quirkless people were treated. He didn't know how well someone who was immortal would take helping a quirkless person. That was like asking a god to help a peasant.

Little did David know Yushiro would have helped. He's a nice guy. "Very well then it looks like we have a deal. I'll be emailing you a list of items we are going to need. It isn't much but I do need these quite soon so do you think you can return exactly a week from now."

He would have to change a few meetings but if this could help his friend, HIS daughter he would make it work. "Yes I can make that work."

"Good I'll inform all the necessary contacts on my end. I'll see you in a week."

"Wait before you go I have a question about quirkless people."

"There's no such thing as a quirkless person. Well at least not for anyone younger than fifty. It maybe weak but everyone should have a quirk now. Izuku Midoriya is proof of that." Said Yushiro hoping David would buy it. 'Damn it I had forgotten that..' thought Yushiro. 'Nana mentioned her successor was quirkless. Did All Might tell him about One For All. David was his first sidekick so maybe. He seems desperate to help his friend as if he's about to do something rash.'

David stood there as silent tears fell from his face. As Yushiro's words filled him with hope for his daughter. David always felt he had failed his daughter when they found out she was quirkless. It had eaten him up on the inside every time he saw her looking on the computer at heros. If he couldn't help her then the next best thing was to find someone who can. "I see thank you so much."

"It's fine we'll talk more next week." said Yushiro as he hung up the phone. "He's definitely a smart one. I'm going to need to come up with some solid lies for him to get him to stop digging into the origins of quirks."

David smile keeps growing as he may have found a way to help two of the most important people in his life. Then his phone rang again. "Hello Mr Yushiro did you forget something."

"Mr Yushiro? No dad it's me, Melissa . Are you okay? Your assistant said you were down, did the meeting go that bad."

"Melissa. Yes the meeting didn't go so well at first but he just called and changed his mind."

"Really that's great Dad so are you two on your way back to I Island."

"No not exactly. In fact in a week you and I will be visiting him here in Japan."

"What?"

~o~

"I see… thank you Lockrock and congratulations on the child." said Sir Night Eye as he hung up the phone exhausted.

"Is everything alright Sir?" asked his very enthusiastic intern Mirio. Both of his sidekicks were also wondering what was going on. Ever since this morning Sir Night Eye had been on the phone calling hero agencies all over the country, he was so busy that everyone else had become nonexistent. He hadn't realized that he ran out of tea two hours ago. He had been sipping an empty cup for awhile now.

Night eye sighed as he collected his thoughts. "I've been calling heroes across the nation regarding the sudden intervention of the military special forces. Three days ago they began immediate raids on the Yakuza hideouts we and some other heroes have been following. Something just doesn't seem right about any of this." he said as he began to rub his forehead.

"I'm guessing I'm missing something here, because to me that sounds like a good thing."

"You need to see the bigger picture Mirio. Bubble Girl, Cenitpider, did we get any message from any kind of official about this or even another hero agency?"

"No Sir we've checked every hour today and yesterday and nothing."

"The military moved suddenly in several populated areas without notifying a single hero and without any official word from anybody. The break too many rules to count and as far as we know they didn't deserve this level of retaliation. What incidents happened with the Yakuza three to five days ago."

Bubble Girl quickly went through the computer. "Nothing from any official hero agency's but it seems that the Demon Slayer kid got into a fight with a small group of them saving a child."

"Demon Slayer!" Night Eye had been trying to figure the boy out for months, he was wrapped up in mysterious and the 'official' reaction made it even more strange. 'Did he have something to do with what was going on?' Night Eye began to get lost in thoughts as he stared at one of his various All Might posters.

"Sir?"

"Mirio if at any time you wish to switch internships I'll help find someone to take you in."

"Wait what?"

"Bubble girl, Centipider. The Same can also go for you if at any point I cross a line that you feel uncomfortable with. Say the word and you can leave the agency."

"HUH!"

"Right now the government is acting strange and somehow Demon Slayer is involved. If the government keeps withholding information and keeps us in the dark, I maybe forced to start doing things off the books."

This left the three in a bit of shock. Centipider recovered first. "Sir do you really think that is necessary?"

"Yes. If things continue this way but for now we will wait and keep an eye on Demon Slayer. Though for now I think it's time for me to reconnect with an old friend."

Yeah this was a setup chapter because things are gonna get crazy for our cast sooner rather than later. Hope you enjoy cause now I can get to some chapters I'm personally excited for.
