Chapter Text

"Toga! Come'here you little psycho!"

The League rolled his eyes, hearing Dabi screaming and the little teen running through their hideout. They didn't really care about it while the arsonist didn't set anything on fire.

Shigaraki and Twice were both playing Mario Kart sitted on the floor, with Spinner and Compress on the couch talking, when the door opened and their newest member entered the place.

"Hey guys!" Hawks smiled, receiving barely a glace from Shigaraki and Twice, and some greetings from the others "Whatcha doing? Where's Dabi and -?"

A little blonde figure collided with his chest, knocking the wind out of him. He barely managed to grab her by the arm before the assasin fell to the floor.

"Hawksie! Help me!" Toga cried, hugging him, the winged hero covered her with his wings protectively, confused.

The appearance of the missing arsonist answered his question.

Hawks's eyes widened. Dabi's hair was completely white.

"Let her go Hawks!" the fury in those azure eyes snapped him out of the shock "I'm gonna kill that brat!"

"I didn't do anything!" Toga replied, watching him from the red wings wrapped around her "We were only playing!"

"Wait, what are you two talking about?" the hero intervened, trying to stop the blue flames licking Dabi's hands to grow even more "What the hell happened? What did you do Himi?"

"I'll told you what happened! This two idiots decided to steal all my dye while I was showering to play with it and try to make slime!"

"Hey! It wasn't my idea! Shut it asshole you're distracting me! -was Twice saying in the argument

Hawks huffed a laugh.

"What's so funny birdbrain!?" Dabi looked at him like ready to roast him

"Sorry, it's just... I didn't knew you dye your hair." the sincerity in his tone calmed down a bit the arsonist anger "I like it, by the way. Looks good on ya."

"Awww~" Toga couldn't help but chirp in Hawks arms "How cute~!"

"SHUT THE F-!"

"Dabi"

The white-haired man turned to his right, were Shigaraki had stand up, watching him bored.

"You're giving me a headache. Stop whining and go get more dye."

"Can't. Doc wants me to help him with something." Dabi said through clenched teeth, crossing his arms in his chest "And it's almost midnight already."

"I'm going on patrol in twenty minutes, if you want I can look for some store still open, and get it for you." Hawks offered with a tiny smile

The arsonist looked at him dumbfounded.

"That would be nice birdy." he muttered feeling a light blush on his healthy cheeks

"Anything for you Hot stuff" the hero winked and Dabi rolled his eyes, Toga, seeing there wasn't any immediate danger anymore flew away from Hawks arms to her room. "Seems you won't be killing her after all, gotta go, bye!'

"Be careful out there pretty bird" with his boyfriends advise as a goodbye, the winged man left.

-------------------------------------------------------------------------------------

" 'Bout time you arrived." that was Endeavor's greeting when Hawks landed by his side at the building's rooftop

"Sorry man, was busy with something" he apologized with a wide smile "Let's go."

They were in Fukuoka, the League had been quite actively lately, their new members of the army knew little about being discreet, and they loved to make some trouble. Crime had increased considerably, so Hawks decided to call Endeavor to help him. Not that he needed, it was just an excuse to spend some time with his hero, but it made the trick.

While they were flying from building to building, Hawks told him about his weekend, with the League. Obviously, without saying who they were or their name. Trough all his talking, Endeavor noticed something.

"Are you on a relationship?"

The blonde almost fell of the sky, taken off guard.

"W-what?"

Enji smiled, seeing his blush with the city lights. "With how you talk about one of you friends, it seems to me that your relationship is more than just that. So, what's her name?"

The winged hero looked away, without answering, Endeavor frowned

"What's wrong? You never shut up" he was sincerely confused and concerned, he hoped he hadn't said anything that hurted his partners feelings.

Hawks landed on a random rooftop, with Enji behind him. He turned his back on the man scratching the back of his neck, nervous.

"It's not exactly a...woman..." he finaly whispered

Enji hadn't expected that.

"You're gay"

Hawks cringed, turning to him "Bisexual, in fact."

"Who's the lucky man then?" The flaming hero rised an eyebrow at the blonde's stunned wace. "What? I'm not going to judge, it's your life not mine. You can do whatever you want"

'If you knew...' Hawks pushed aside any other depressing thoughts and smiled to the red-head in front of him. "Why the interrogation?"

"Just curious, that's all."

The young hero opened his mouth to answer back when an explosion shaked half the city, interuping him. The two of them shared a look before shoting to the sky again, to the source of the noise.

-------------------------------------------------------------------------------------

" What's with the change of style?"

Dabi rolled his eyes at the doctors laughter "Tell me what I have to do and I leave, got it?"

"Of course" Kyudai pointed to the tanks at his right, filled with nomus on the making "You know that i've been trying to create the best nomu to our dear leader for a while now. I want to build one that can handle higher temperatures that Endeavor's fire itself, to make them almost indestructible. And for that, I need your help, or better said, your quirk."

Dabi's blood ran cold.

"You want to use me as a guinea pig" his calm demeanor betraying the burning rage starting to form inside of him

"I could help you, fix you" the doctor looked him up and down

Dabi greeted his teeth. "I don't need to be fixed" he growled, blue flames on his hands

The doctor laughed "Now don't be a fool, you can't kill me, and I doubt Shigaraki will let you do it any way. My knowledge is too valuable for him.

"I don't think he'll care while I don't kill you!Dabi screamed "I won't let ANYONE use me AGAIN!"

A gigantic sea of blue flames were sent to the doctors face, who disappeared with a chuckle before they could hit him. The arsonist roared shooting another attack to the man when he reappeared in front of one of the tanks to his left.

He realized his mistake to late, Kyudai had been swallowed by the black substance they all knew again, the tank exploted, freeing the creature inside of it. 

Before Dabi could react a tentacle shot from the smoke hitting him on the chest and sending him to the opposite wall. Letting out a scream, he fell to the floor. His body was on fire, the staples had tore part of the healthy skin of his back with the impact, hopefully he wasn't bleeding The villain looked up in time for his azure eyes to see the abomination make a hole on the wall and disappeared.

"You shouldn't have done that" the doctor sighed, watching him get up with shaking arms "But well, I was going to test it anyway, better sooner than later don't they say?

The man walked to his computer, and Dabi saw in the screen the nomu causing havoc. Kyudai had hacked the security cameras nearby the creature to follow it's movements.

"What quirks does that thing have?" Dabi muttered, going closer to the other

The doctor smiled. "They're about to find it out."

The arsonist heart stopped beating, seeing the two figures who had just landed in front of the nomu.

Hawks and Endeavor.

-------------------------------------------------------------------------------------

"Woah, it's a big one." Hawks chirped, eyeing the grey thing from head to toe. "I hope it's not a High end, right Endeavor-San?"

The flaming hero gritted his teeth, without answering. The nomu in front of them looked normal, it was big and grey, with those eyes and ugly face, but at plain sight it seemed it was a normal one, while it didn't talk...it wasn't a High End. The creature's strength was abnormal as it had already shown, but they didn't knew which other quirks could the nomu have. 

It seemed it had a good sight, they have been spotted. With an animalistic howl, black and sharp tentacles shot from it's body to the two heroes. Hawks flied away from their reach, shooting some hardened feathers to cut them and the nomu. Endeavor shot a wall of flames, unfortunately for the two of them, it didn't do anything but making it even more angry, the cuts of the feathers had already healed. 

"This thing is fireproff!" He growled to the blonde "And has accelerated healing!" 

Hawks rolled his eyes. 'Perfect, just what we needed.'

The nomu threw again a mass of tentacles that they ducked, but they weren't only aiming to them.

"Endeavor-san!"

The red-head turned to his left, were a building was starting to collapse. "Fuck!" There was a family under the upcoming debris.

He launched himself to them, taking them out of the way while Hawks used his feathers to evacuate the people inside.

"Everyone get out of here! Now!" Endeavor screamed to the crowd who left in fear, a loud moan make him tense. He turned again, seeing a tentacle cut through his partner's left wing. "Hawks!"

The named collied with the ground with a muffled screech. Enji shot a flare to the abomination, making it go back, away from the blonde. 

"Hawks! 'You alright!?"

"I'm fine, it's nothing" the young man got up, flexing his wing, it was bleeding and it hurted like a bitch, but it wasn't that bad. "I'll live."

The nomu roared, fed up of them getting in the way, it may not talk, but it had emotions. He attacked, but this time, it was something more subtle.

"What's it doing?" Endeavor saw it moments before it happened. Tentacles, moving under the floor, to them. "WATCH OUT!"

Hawks shot to the sky moment's before they could impale him, hearing Endeavor's warning. But the man hadn't notice that they were going for him as well. "ENJI!"

The flaming hero found himself on the floor suddenly, he looked up and his breath got caught on his throat. "No..."

The blonde had one tentacle on his stomach, and other on his shoulder, going through him. He cough, blood spilling from his wounds and mouth, his golden eyes on the red-head. "E-Endeavor-san..."

The tentacles retracted, making Hawks scream before he collapsed to the ground, immobile.

"NO!"

Everything burst into flames.

-------------------------------------------------------------------------------------

Kyudai watched the different feelings that crossed through Dabi's face while he was busy seeing the heroes fighting his nomu. Curious. He knew the arsonist hated Endeavor, but that grimaced he had done when Hawks have been hurt by one of the nomu's tentacles, confused him. What would it be their relationship?

"Send me there." He blinked, his eyes on Dabi

" Pardon?"

"Send me there." The villain repeated with a growl. "Endeavor's mine, I'm not letting that thing take away my vengeance."

The doctor raised an eyebrow but nodded. Dabi felt the familiar taste of the black substance in his throat, and in matter of seconds, he was on the street. A flew blocks away from the fight for what he could hear.  He ran.

'For fuck's sake. You better not be dead birdy or I'm killing you.' 

He arrived at the square, at the same time that the black tentacles impalated said bird when he threw Endeavor away of the danger. He watched them retire and the blonde fall before his brain could process what he was seeing.

No..."NO!" 

Not even knowing what he was doing, he launched to the nomu with an inferno of blue flames on his hands. Only one thought on his head. Destroy that damn thing.

He didn't care about the pain it brought using his fire at his hotter temperature, it was worth it while it melted the nomus body, nor he cared about the fact that the staples of his left arm were melting as well.

He did not care.

Blue flames engulfed everything, forming a circle with Dabi, the nomu, and Hawks in it, burning everything on it's reach, even the security cameras couldn't resist the heat. Endeavor watched from afar, dumbfounded. What the hell was Dabi doing there? He didn't knew, trying to see something between all the fire and the nomu's shrieks. Finally, silence fell, and the flames lowered enough for him to see Dabi collapse on his knees, holding one arm and literally fuming all over his body, breathless.

Gasping for air, the arsonist forced himself to rise on his feet before running to the winged hero on the floor, kneeling beside him.

"Birdie!" he turned him, puting his head in his lap, his azure eyes eyeing the blonde's injuries "No no no no no no..." His right hand put pressure on the wound on his stomach, Hawks was breathing although shallowly, thank god "Birdie?"

Golden eyes opened barely to see him, Dabi wanted to kiss him so badly.

"D-Dabi?" Hawks didn't knew how he was there but he smiled "H-hey..."

The arsonist barked a shaky laugh, "Hey pretty bird, you're...gonna be alright okay?" He tried to convince himself more than the hero "Just...hold on, ok? Hey!" He shook him when the birds eyes closed "Don't you dare close those precious eyes you hear me?"

The winged hero coughed, Dabi panicked seeing the blood spilling from his mouth. And the feeling of warm blood sipping from his wound and through his hand on his stomach, as well as the other two on the shoulder and wing of the man sicked him.

The two words his boyfriend whispered broke him. "D-Dabs...i-it h-hurts..."

"J-just hold on please, birdie. Help must be on the way..." he tried with broken voice, blood flooded from his own eyes "Y-you..."

Dabi didn't care if he was arrested, he prefer it if it meant that someone would save his birdie. He would never forgive himself if he died. 'God...this is all my fault...'

They didn't notice Endeavor's presence, watching them, the man was petrified. He couldn't understand. Seeing Dabi now(with white hair) helping Hawks... He didn't understand anything. What the hell was happening? He didn't dare to try intervene.

The villain winced when he took out his phone from his pocket, using his injured arm. 

Compress answered right away. "We're on our way" the man told him, the sound of a car o something like that muffled on the background "We saw everything, Toga's prepared, Spinner and I are going for you two, hang on a little more."

'Oh fucking god...' Dabi couldn't ask for better friends "Thanks"

"Always, hold on, ok?"

The arsonist hang up and focused on the hero on his lap, he's eyes were open in slits and slightly unfocused "Hey, help's on the way, 'kay? Don't fall asleep, stay with me pretty bird, you hear me?"

A weak nod was his answer. Hawks could feel himself running out of time as his strength faded away with every drop of blood flowing out of his body. He wanted to tell him something, but everything hurted so much. 

"T-Touya..." He gathered the energy to speak, his voice barely a whisper, noticing the white-haired villain tense when hearing his real name. "I-I..." A cough ripped it's way from his throat, leaving him breathless and in a world of agony, he tasted blood again, he had to hurry

"Hey, birdie, don't. Don't talk" Dabi caressed his cheek, Hawks could see through his blurry vision the blood on his face. He was crying, for him, he had to tell him. Before he couldn't anymore.

"I-I...love you...T-Touya Todoroki..." The villains heart broke in a million pieces

" I-i love you too K-Keigo Takami" he whispered back, he couldn't take it anymore, he kissed him. Hoping. Praying. That it wouldn't be their last together. 'This can't be the end for fuck's sake.'

Enji Todoroki felt his world stop turning, when he heard that name leave Hawks lips. 'It can't be...' He thought, horrified. 'M-my son...T-Touya...h-he's alive...'

It was like the missing piece of a puzzle, now all made sense, everytime he saw Dabi came back to him with a different meaning, Hawks words about his boyfriend...How couldn't he saw it before?

Dabi broke the kiss and his heart dropped when he found the hero's eyes closed. "Kei?" He shook him "Keigo!"

Nothing.

"No..." his voice broke "You can't do this to me... Kei? OPEN YOUR FUCKING EYES! He sobbed, dropping his head onto Hawks's, closing his eyes. "P-Please..  Y-you...you can't leave me birdie...N-not like this... P-please pretty bird...don't leave me...I'm so sorry...

A white van passed through the ring of dying blue flames at full speed, coming to a stop meters from the villain and hero on the floor.

"DABI!" The doors opened and Spinner hopped from the vehicle with Compress behind him, from the driver's sit. "Oh my god, Hawks!"

With the lizard's help, Compress and him managed to lift the miraculously still breathing hero to the van, being careful with his injured wing. The illusionist helped Dabi to his feet, who seemed that was going to collapse at any moment, leading him to the van as well.

Endeavor, finally found his voice, seeing them about to leave.

"TOUYA!"

Dabi turned around so fast that his staples ripped open part of the healthy skin on his neck. Two identical azure eyes met. The villain looked away, unable to bear the horror and pain in his father's gaze. The doors of the van closed behind him.

Enji didn't notice when the other heroes and the authorities showed up, or the news helicopter that apparently had been flying above them, neither did he heard their voices asking him questions. His phone rang, and he found himself answering, his eyes never leaving the last place where he had seen his son.

"Tell me it wasn't him...TELL ME IT WASN'T HIM!" his other son begged him, sounding so desperate,  but he couldn't lie, not anymore, not to his family

"It was..." He whispered to the phone "Touya's alive..."
