In the world full of unique quirks possessing a healing power was like a kiss from fortune. There weren't many people who could use this type of power. With villains on the rise this kind of thing becomes worth more than gold. Of course for a person who possessed this kind of power it wasn't just fun and games. Constant work with id…. heroes could burn out anyone. That's why she wasn't too happy with the sudden request for her attendance in Japan. It wasn't her dream coming true. Long airplane ride from Europe hasn't helped her mood.
She was grumpy and tired. It's not like it was different from her normal work mood of course. She chose Nightingale as her hero name. Some speculated it originated from how she always sang songs when using her healing power. It couldn't be farther from the truth. She chose it because nightingales were small and annoying in the morning. For an European woman she was short, more in Asian standard like she liked to joke.
She sighed even though she had a pair of wings, flying from Europe to Japan wasn't worth the effort because of the energy it would take. She neatly tucked them behind light poncho. The look of them was quite unique and she didn't need any attention. Her wings were her mana manifestation. The more energy she had the thicker the feathers were. If she used energy after certain amount, the feathers one by one would start to disappear.
She sighed again. The circles under her eyes were as heavy as her mood when she slowly walked towards the big flashy sign saying "Welcome in Japan Nightingale". She murmured under her breath. Sure why not? Maybe also add gun salute to it? Duck being incognito.

" You could just say who I need to find." She said trying to look cool and not to yawn. Damn you airplane.

"Oh of course, it seems like you are a tired miss, you will be staying at teachers quarters as was said in the letter." Said short person with the appearance of a mouse.

" I didn't memorise it fully. I know you need healing support and that's all I care about. We can talk fully about details when I rest a bit. Damn I had to heal a woman who went into labour." she started complaining. It's not like she didn't like to help people. She wouldn't work here If she didn't. Well she would because money was good but it wasn't her only reason. Her grumpy mood came from a complete lack of sleep from the past two days.

" Your Japanese is pretty good young lady." commented a tall man with blonde hair. He wanted to change heavy atmosphere

" Thanks. My friend used his quirk on me… I'm almost always in a hurry." she muttered

" Let's go to the car, you can rest there" she gladly accepted. Any rest was welcomed.

" Sorry for being late, my first plane got delayed and it all become messier from there" she sighed

"How is your energy level?"

"Work already? Pretty good, I wrapped myself in my wings so they won't cause trouble"

"Great… the action that we planned… didn't go like it was planned and" started Allmight looking troubled at the woman. He heard many things about her and was hopeful she would be a great help in their case.

"Please lead me from room to room according to the severity of the cases. I should be able to help at least fifty people in grave condition. If I have a snack break during healing I'll be able to help another 34." she said sharply.

"The worst cases are tops but even kids got injured."

"Said a man with half organs missing" She snorted, shocking the retired symbol of peace who suspiciously looked at the young lady. She sighed "My quirk would be only half effective if I could heal without knowing what's going on. That way I can decide on parts that need my attention."

"That's pretty amazing miss"

"It's useful and it makes up for my total lack of offensive skills. Of course that's why I have gun but…" all three men got quiet for moment

"Gun?"

" I know it's hard to find info and contact me but it should be known to you I got the colonel title during my work with the military. They for sure loooove their ranks. I can only protect myself by making a shield from my wings so I'm using a gun. Of course I can smack someone with a wing but you have to say the gun is more effective" she took out a beautifully decorated white Venetian mask. It covered her eyes and part of her nose. " I heard you really like costumes. In the army I would wear a plague doctor outfit as per request from higher ups but learning about kids I figured out they wouldn't be too happy with it." she chuckled and the rest of the passengers relaxed visibly.

"We should arrive in two minutes, one of the nurses will lead us."

"Roger." she said calmly and strapped her bag better.

She let out a sigh after the worst load of work was done.

"I was shocked to see you have kids in the top ten of your rankings." All might get a bit abashed.

" If it was up to me I would also wait…"

" Miss, aren't you also 23?" Asked the mouse man.

"Yes, thank you for your notice but I come from a country where there was war. It's a different situation, so all is left for me to greet the youngsters you want to train as weapons against…" she checked documents "league of villains?"

"Exactly. Will you help?"

" If I can help with making more kids survive I'll lend my power to you" she bowed and stretched her wings. She lost a lot of her feathers but still would be able to heal if there was need.

" The kids are waiting here. They mostly needed patches and probably would need some cheering" said the nurse.

" I'll talk with them first." said Toshinori "I know how they feel."

" Oho I feel like I need to prepare for the main concert part after a great opening band." she said and adjusted her mask. She couldn't hear what they were talking about. She smiled at herself. She was more afraid of making a good impression than healing. Healing was easy, that's what she was doing for most of her life. But human interaction? Man that's the hardest part!

"I told them they have a special guest miss, do you want me to go with you?'' asked the blond man. She shook her head.

" I got this." she said with confidence and went inside. She looked at a group of kids and took a deep breath "Good evening to you. I'm Colonel Nightingale, I'm 23 years old. Currently I have no place of my own since my work requires me to travel. I'm yet to marry.
I need to have my energy in check since it is required for work. I can go with a little amount of sleep and still be able to function pretty well. I don't like people dying on me so I found the easiest solution for that. Heal quickly enough to not let anyone die.
That way I can go to bed without worrying and sleep like a baby…" she started talking, not sure what the hell she should tell these kids.
She was holding her hands like to prayer all the time. It was out of reflex when she was healing someone.
They could easily see she lost some more feathers during the talk. Green haired boy raised his hand after feeling a warm sensation in his body and lack of feeling pain after a moment.

"Miss, what exactly is your quirk?" He asked curiously 'how direct' she thought before sitting on the free chair.

"I possess the healing quirk. People call it a blessed song but that's just bullshit. I can heal any organic organisms, be it land, animal or human. My quirk is weak against viruses but does great against any damaged cells. In other words it will be highly effective against broken bones, missing limbs, cancer but could be proven useless against common cold"

"How does it work? I feel like we all have been healed, it had a nice and calming feel to it. I saw you had your hands together, do you need to do that to use it?" He asked writing it all down in the notepad. She sighed. She needed to trust these kids since they would cooperate together.

" It's a mutated quirk. It's activated at will after I use the second part of this ability that is checking what exactly needs healing. Normally I would sing so no one will have an idea what exactly is activating it. It saved my life on a few occasions since people think damaging my vocal cords is enough to make me useless.
I can easily remember body energy and associate it with people especially if I don't have to heal them fully. My power radius is around 50 meters so please if I'm working as your support don't go too far. My power level is easily checked. The more feathers I have in my wings the more energy I have. As you see I lost around 50 percent of them. You are my last stop in hospital.
It can be easily replaced by eating and sleeping so it's not a problem. If there was an urgent need I could probably refill my energy fully 2-3 times before my body would give up" she hoped she gave him a satisfactory response.
Seeing how radiant the boy became she sighed taking it as yes. " I'll need some time to learn all your names, so please take care of me" she stood up and bowed like a knight with one arm stretched and a second bend on her chest. Her now short wings followed the lead of arms. Kids whispered between themselves before tall brunet got up and bowed to her

" Class president Illda, I'll introduce everyone". She greeted every person personally and sighed.

" Remember, even if you don't win battle… if there is hope and will you can always reach out and grasp back what's stolen from you. I'll do my best to support you so please now rest a bit more." she said with a smile and left them at that. She let out a sigh looking at All Might talking with current Japan number one.

" So this is the special help you found? Hope she will be useful."

"I healed your sorry ass so watch your language." she responded angrily. Man gave her a dead stare but was met with something more powerful, a woman furry.

"Please, I don't think we will be able to find someone with a more powerful healing quirk. As you see the whole hospital is healed by now." the taller man snorted.

" They probably changed their location by now anyway. Someone will need to show her the ropes. You, how are you called?"

"Colonel Nightingale, but Nightingale is enough," she answered, saluting.

" Great, how is your work method?"

" Effective sir"

"Don't joke with me!" He said angrily and she could see some small flames forming on his moustache. She let out a sigh.

" My main job is to make sure people are in good condition. I can protect myself with my wings since they are great shields and slam someone with them but that's it. My main objective is to be fast enough so no one gets hurt. I also use a gun with different bullets."

"Another fast brat. I know who will be in charge of you."

" We thought her help would go well with kids training, you can't be so hard on people, Endeavour."

" We don't have time for being nice. Besides she can do both like most people."

"I don't mind. Since I can easily find people with specific injuries. Besides being in the army, being a hero. Seems like everywhere you have an asshole supervisor."

"You better watch your language. You will be informed soon about details."

"Roger!" She answered angrily.

"Miss I'm sorry, he is not a bad person but…"

" He has a bad person's energy." she murmured. All might sighed with worry and ran his hand through his hair.

" He is not that bad. Anyway let's take you kids back to school. You are probably tired from all those things."

" I'm okay. But the kids will need probably a really great peep talk to raise their spirits"

She didn't get much time to rest since she was called right after they showed her room in the teacher's dorm. If it was possible her mood would become even grumpier. She hoped they would give her at least one night of good sleep. She let out a sigh going inside the room the men in suits showed her. In contrast to rest she was wearing her civilian clothes. She growled seeing Endeavour sitting on one of the chairs.

" Miss Daiana Filin?" Asked men sitting behind desks." I'm Tamaki Aoi, I will be one taking care of miss case so in the future ask for me please"

" Yes, nice to meet you sir." She took out her id and handed it to men " sorry if I knew I would change into more proper attire, never would dare to guess someone would be so rude to call a person after sixteen hours of travel and quick rescue work." she said with a bright smile.

"I-i'm sorry we are understaffed and…"

"Please. The faster we get this thing done the faster I will be allowed to hit the bed."

" Yes… Miss knows why we contacted you and signed contact."

"Yes. Yes, you hope I will be helping with healing injuries during the fight and be usable against decay quirk, that's correct, right?"

"Yes and…"

" Person localisation based on injuries. Understandable. You think he will be back in the capital?"

"Yes since his master is here."

"Understood. I will start patrolling tomorrow." she answered and took back her id and also small plastic card. Hero license. She smirked. They didn't have such fancy things back home.

" Please wait a moment Miss!" He stopped her when he noticed she wanted to go out.

" You are a foreigner. Yes we need your help but we don't fully trust you… yet" said Endeavour while getting up. He tried to remember to not be so hard on people. She let out a sigh.

" So you want one of your dogs to accompany me to make sure I'm not just an evil European spy?"

" Someone will have to show you how it's done here. And the second part is a yes." he said with a stern expression. The person behind the desk coughed slightly.

" Let me introduce you, he is one of our most trusted people and…" he started enthusiastically before she cut him.

"Please skip the small talk."

"Uh yes…" he said, a bit taken aback.

" You could tell me sooner we will be having another bird bud!" She heard a cheerful voice. She murmured. 'great. Another one' she thought before turning to voice direction. She froze in her place looking at the man in front of her. Her cheeks got almost as red as his wings. She kinda hoped to meet him from the moment she learned she would be going there but witnessing it with her own eyes so soon? She was amazed by his assets.

" Oh my… what a nice view. Such strong and long features." she said going around him. He smirked and before he had a chance to say something he squealed when she pulled out one of his feathers. " Great condition, seems pretty strong on its own" she caressed it with fascination on her face before the man angrily slapped her hand with said feathers.

" You shouldn't take someone's feathers without asking!" He said angrily. Few people chuckled from the show that was happening in front of them. She let out a sigh.

"Sorry I couldn't help. I always gather some feathers for my organisation to run some tests. Yours are one of the nicest I touched" she said without any remorse or regret.

" Glad you two are getting along. Hawks that's your new objective. You will be responsible for showing ropes to miss Nightingale and miss Nightingale; he will be responsible for you for now. Any questions?" Said a man who started to look as tired as a woman after her journey.

" No sir. There is no need to waste more time on such frivolous matters" she said and saluted with her wing.

" Let's talk about details and …"

"Just give me your number and we will discuss the details before tomorrow's meeting." she said, looking at him with a bored expression. He sighed, taking out his phone.

" You can discuss things outside. I have few things to discuss here." said Endeavour.

" As expected of number one." Hawks answered and gently pushed Nightingale out of the meeting room. Feeling she took his feather again he angrily took out a paper bag from her big bag.

"Oi, that's my sandwich… or chicken nuggets, or maybe that was croissant" she said angrily.

" Hey you took my feather I took your…" he curiously opened a bag and ate one of the nuggets " chicken" he said with a smile. Her face got murderous look

" Oi chicken wing that means war!" She said angrily " my phone number is" she started saying her number. When he called she saved him as chicken

" So instead of Nightingale should I call you magpie? Since you like shiny feathers?"

" Mine have nicer shine, besides you have an average size of wings."

" They are a bit longer than six metres." she smirked at his words

" Mine are seven but can get a bit bigger with proper training." she said proudly. He looked at her for a moment. She was slightly shorter than him since her head was reaching his eye level. Her puffy dark blue hair was a short mess, excluding two strikes going up like owl fake ears. He smiled and grabbed her cheeks. She was soft.

" Oi, what's wrong with you and the wings measure war!" He asked, pulling them slightly before releasing her. Her golden eyes give him a murderous look.

" You are just jealous since they are so long." she stretched one of her wings with a proud smile " see? And now they are small since I used so much energy to heal a bunch of ungrateful heroes." she said and yawned." I'll have my revenge for the eaten chicken after I sleep enough." she murmured and started heading outside.

" Wait, first Tokyo is not my region so let's hope we won't have to spend that much time together and second… you are responsible for healing us after the attack?" He asked curiously, looking at the grumpy woman.

" Yes I did. That's why I'm so sleepy since it's been a few hours ago and I just got here." she murmured angrily. His expression softened before he smiled.

" Thanks for your help. I bet most of us are alive thanks to your help!"

" That's my job. Being faster than death. I heard you fly too fast for your own good, so probably that's why we ended together. Don't worry. If you are close to my radius I can protect even the chicken wings of yours." she pointed at him while doing finger guns. " I don't like seeing kids get hurt."

" I'm 23 you know!"

" Such a pure age, I'm 24 since few days"

" We are same age then, it's uncommon to find someone this age to work alone"

" Probably. I spent most of my life in the army before getting out. Anyway I'm going back. We can discuss the rest of matters via phones. And one more thing. You don't have to be so stiff. Maybe try acting more natural?" She left him at that without explaining what she means.
