Obachaji Kaminari had spent most of her internship goofing off with her father, Denki Kaminari, but she honestly didn't mind wasting the time meant for training. Like most children with pro heroes for parents, her mom and dad were often on missions. Obachaji even dared to say she enjoyed the time spent with her mother, she learned how to play a guitar and operated sound stage equipment. With only two days left to enjoy their time together, Denki talked the girls into going out for ice cream.

"When I first started learning how to control my electric shocks, I tried dialing them back until it didn't really fry my brain as much. Maybe you should try releasing yours the same way!", Denki was currently trying to coach his daughter when it came to the use of his inherited quirk.

"And your earjacks are much more useful than just listening through walls! You can also excrete sound!", Kyoka chimed in when it came to her inherited quirk.

"I know!", Obachaji groaned. This was the millionth lecture from them.. that DAY. She plugged her earjacks into her phone to listen to some music and hoped her parents would leave her alone.

"Hey honey, I got an idea! We can invite Midoriya over and have him tutor her! He's always been good with other people's quirks!", Denki turned his attention to his wife when he saw Obachaji ignore them.

"Well, I suppose you're right about that.. after all, he was the one to help you learn how to stop short circuiting yourself.", Kyoka half agreed/half teased her husband with a playful shove.

Denki opened his mouth with the intent for a comeback, but was jolted back by his wife. "Hey, what gives?!", he shouted. Obachaji took notice of the sudden stop and also raised a curious eyebrow, but didn't bother to turn down her music.

"Oh no.. not that bitch.. let's go somewhere else.", Kyoka growled in a hushed whisper to Denki. The confused blonde turned his head to see who his wife was talking about, but received a whack from one of her earjacks as a result. "Don't look, ya idiot!"

"Hey! Hey, Kaminaris, over here!"

Kyoka and Obachaji mouthed an inaudible 'fuck', both unprepared for human interaction.

"Oh, hey honey, look, it's the Seros!", Denki smiled and politely waved back at the family. He then caught the annoyed expression from his wife and daughter, "Ooohhh..."

Bottom line, the Seros were too upbeat and cheerful for the female Kaminari's liking. Regardless, they were forced into interacting with one another now.

…

Iris Todoroki had been forced into a corner, barely holding off against the rapid fire of lasers. Her usual sparring lessons with Spectrum Forge ended this way. A rule had been set in place to improve the young Todoroki's range of creativity. After creating an ice construct once, Iris wasn't allowed to make the same object during combat. The intern could only think of a few ways to shield herself from the bright beams of her mentor before running out of options to defend. Iris created a escutcheon to block a glowing hammer from Spectrum Forge while mulling over other possibilities of protecting herself. As the ice crumbled away and Iris slid back on a slick surface, she watched her mentor conjure a lance. The shields and swords the two kept creating during their match continuously resembled a battle between knights. That's when an idea dawned on Iris.

The heroine in training felt a shiver run up her spine as she began to use her quirk on herself. The ice began to encase her arms first, a hard coating spread further across her body. Much like a knight, the young Todoroki was soon wearing armor. Astonishingly, the ice acted like an exoskeleton and provided perfect mobility. Iris then worked off of the frosty hauberk to retaliate with protrusions. The ice lengths acted like tentacles as they reached for Spectrum Forge. The pro hero created a glowing machete to hack through them like undergrowth. Iris flexed her fingers like the severed pieces were other appendages and made those ice fragments shed protrusions as well. They would soon overwhelm Spectrum Forge and she'd be bound by the newly improvised attack.

Spectrum Forge wriggled and writhed in the restraints before tapping out. "You've come a long ways.", the pro hero praised her intern. The victory meant a lot to Iris, considering it was her first time winning while sparring with Spectrum Forge. The young Todoroki had also learned two new moves that could be incorporated into future maneuvers. The ice unsheathed and receded on both heroines before Iris helped her mentor get off the floor. "I think that's enough training for now. What do you say to a lunch break?", Spectrum Forge shared a hungry grin with her apprentice. The question was answered when the young Todoroki's stomach growled and Iris was forced to respond with an eager nod.

"I've been meaning to try a new noodle shop not too far from here. Mind if we eat there?", Iris hoped her suggestion would be considered. Spectrum Forge couldn't help but giggle when seeing the pleading expression on her student's face. Kasai had recommended the restaurant and Iris desperately wanted to try its ramen.

"That sounds fine with me, but you're paying.", Spectrum Forge couldn't resist teasing the girl. Much to her surprise, Iris didn't groan or complain about it. The young Todoroki came from a wealthy family and received a hefty allowance as the result. "I- I was only joking about you paying!", the pro hero tried to take back the burden of buying the meals. Iris was polite and humble enough to reassure Spectrum Forge and uphold the promise of paying for the bill.

Much to the duo's surprise, they weren't the only ones that decided to eat at the specified restaurant for lunch. Kasai had somehow managed to talk his own mentor, Shoto Todoroki, into taking them to the same place. Iris wasn't too thrilled to see her father again so soon, but she enjoyed the company of her friends. Hikiyose was quick to make conversation and not so discretely mentioned Kasai's plan to get them into the same noodle shop for lunch. Iris appreciated the gesture and carried on with her friends while the pro heroes got their own table to converse at.

The day turned out to be one full of surprises when another sensei entered the restaurant. Izuku Midoriya basically skipped into the noodle shop with girlish waves. Shoto raised an eyebrow at this, it seemed way too out of character and a tad suspicious. The whole group was shocked to see Izuku, but his daughter was the first to make an audible response. "Dad?!", Hikiyose practically cried out.

Izuku paused for a moment, his gaze shifted to Kasai and back to Hikiyose. The man gave a slow nod to his daughter and the massive grin on his face somehow widened. "Yes, that's me! Totally your father! How's daddy's little girl?", the greeting made Hikiyose groan in embarrassment. Kasai had to hide the fact that he rolled his eyes by face palming. Shoto's suspicions continued to raise as he watched the interaction and Spectrum Forge remained out of the loop. The shining heroine decided it was best to stay out of it to avoid making things any more awkward.

"So.. Midoriya, what do we owe this unexpected visit?", Shoto cleared his throat to gain everyone's attention and chimed in. Izuku's grin faltered a little before settling into a sly smirk.

"Oh, Shoto-Kun, you're so silly! Why else would I be here?", Izuku surprised the half & half hero by invading his personal space. A mild massage on the pro hero's shoulders was odd coming from Izuku to say the least. "I was hoping to speak with my students for just a teeny tiny moment, specifically Iris and Kasai!", he elaborated in a sing song fashion.

Shoto was about to pry further, but was interrupted by the scraping of the chair legs scraping as they were pulled out. Kasai and Iris had both stood up, willing to follow their sensei and unaware of his strange behavior as far as Shoto could tell. Izuku's smirk turned back into a toothy grin as he lightly tapped Hikiyose on the nose, "Sorry to leave you out darling, maybe next time."

The next person to stand up was none other than the number one hero himself. "I'm going for a walk. Spectrum Forge, please stay here and watch young Midoriya for me.", Shoto strolled towards the door while giving his orders. Just to be safe, the half & half hero planned to follow Izuku and the children he had taken with him.

…

It had been a quiet day in Hatsume's workshop, she had even decided to close early. Keeping that in mind, it came as a shock when hey boyfriend kicked open the door with The Green Shadow slung over his shoulder. The vigilante looked completely drained, his face mask equipment had been removed and the lack of a face guard was showcasing his pale skin. What shocked Mei even further, was her boyfriend's attire. There was obviously a lot happening all at once, but the mechanic was quick to act on saving her friend's life first.

"What happened?!", Hatsume rummaged through a med-kit while asking for the details. Mei didn't need to use the miniature flashlight to see the vigilante's pupils were dilated. The Green Shadow's eyes lolled about, rolling around and daring to fall into the back of his head. Hatsume placed a hand on the victim's forehead, expecting a fever but discovering cold & clammy sweat. "Wet a washcloth, make sure it's cold water!", she barked an order while waiting for the prior question's answer.

Bakugo grumbled to himself, but obliged and followed Mei's instructions. "The dumb fuck got himself stabbed and his shitty blood drained from a crappy device.", Katsuki recalled the alley fight with Himiko Toga.

Hatsume did a temporary job of patching up the knife wound before racing to a locked cabinet. "He'll need a blood transfusion then! Do you know what type he is?!", Mei unlocked the case and dug through emergency blood bags.

"Why the fuck should I know? I think it's fucking O..", Bakugo huffed as he shared the information. When they were children, Izuku's mother had sat with Katsuki and given him all sorts of emergency information, including medical history. Inko had been one of those overprotective moms, and the worry for her son's safety paid off.

After Mei managed to hook up the proper equipment and blood pumped into the vigilante's veins, she allowed herself to relax a little. The stab wound had already been treated and just needed to be stitched, and then her work would be done. As the mechanic tended to the recovering vigilante, Bakugo couldn't help but watch in fascination. "How did you get so good at bandaging and shit? Were you a nurse at one point?", Katsuki shifted uncomfortably as he asked the question. If he had been upfront about his alter ego like Deku, then Mei could have saved him the trouble of ice baths every night. Any scars from the anti-hero's outings were left as permanent markings due to the lack of treatment.

"When you blow up half your inventions, you kinda need the extra blood and bandages.", Hatsume sheepishly rubbed the back of her neck. Bakugo scoffed at the action, it reminded him of Izuku and the answer sounded more like an excuse. It was now Hatsume's turn to scoff and ask a question, "So, are you gonna tell me why you're wearing that getup and were able to bring back Deku?"

Bakugo hung his head, he didn't know if it was in shame or anger that she found out. "It's true, okay? Fuck. I'm a vigilante like shitty Deku.", he avoided making eye contact but managed to face Mei.

Hatsume crossed her arms over her breast, "Why didn't you tell me sooner?"

That was the part Katsuki wanted to avoid. He feared that she would react like Deku, or worse, that she would be scared of him. "I'm.. I'm not a pussy vigilante like fucking Deku over there. When I fuck up a bad guy, I make sure they stay the fuck down.", Bakugo dared to look at Hatsume again and saw she didn't fully understand what he meant. "I kill them, dammit Mei, I kill the fuckers! Is that so bad?!", Katsuki couldn't help the outburst that followed.

Hatsume was the one who couldn't face the other now, she shuddered thinking about her boyfriend being a murderer. "I get it now.. that's why you wanted me to go with you to Deku's house, that's what led to all of this. You knew Deku would get in your way and.. used me as blackmail?", Mei began showing the same anger as Bakugo as she pieced the fucked up puzzle together.

Katsuki resisted flinching at her reaction and reached for her, "It isn't entirely like that..", Hatsume harshly pulled away from his hand. Bakugo's frustration got the better of him and he snapped back, "This is why I didn't fucking tell you! Let me guess, you're gonna say I'm just as bad as the fucking villains, right? You agree with shitty fucking Deku?!"

"You aren't doing anything to show me otherwise! You USED me, Katsuki! You used your girlfriend! How do you think that makes me feel?!", Mei began yelling back. The two had trouble suppressing their anger at this point and let it all out through tears and shouting.

All of the screaming managed to wake up The Green Shadow, he stirred on the mattress and slowly gained his bearings. A weak and heavy hand found itself tugging at the IV, the vigilante barely made out the machine through blurry vision. His ears continued picking up the raising noise of his friends arguing, both of them flinging valid points at one another. His tired and meek voice came out as a whisper that he didn't expected them to hear, "Stop fighting.. please.."

"Deku, don't sit up, take it easy!", Mei dropped her attitude and quickly rushed over to her patient's side. She reassured the injured vigilante that the argument was over and tended to him while ignoring Bakugo's presence.

"Yeah. It's over.. For both of you.."

The statement from Katsuki startled both Mei & Deku. "What the hell is that supposed to mean?!", Hatsume hissed in anger.

Bakugo simply waved the mechanic off and briskly exited the workshop. The other vigilante could no longer lay back and do nothing, so he propped himself up on his elbows to lean forward. Despite Mei's protests, The Green Shadow climbed out of bed and unhooked the IV.

"I've gotta go after him..", Deku staggered towards the door while pulling on his mask.

"You need to rest, why are you bothering with him anymore?", Hatsume was still crying from her argument and it leaked over into the current predicament.

The Green Shadow snapped his mouthpiece into place, completing the mask. He gave Mei one last glance.

"Because.. he's my friend."

Mei shook her head in exasperation.

"Deku.. I don't think he is.. not anymore."

…

Iris had been so distracted by her conversation with Kasai, that she didn't realize Izuku had led them into a bar. She finally took in her surroundings, noticing the place looked brand new, like it was completely prepared for her arrival. Her confusion must have shown through, because Izuku and Kasai were already explaining the situation.

"Don't be mad, don't freak out, just keep an open mind.", Kasai sounded like he was pleading to her.

"We went through a lot of trouble to get you here! I can't believe it's finally happening!", Izuku couldn't stop hopping up and down in glee with a self applause. She now understood why he had done things like this consistently, the out of character actions & remarks suddenly became painfully obvious. The green haired man that she knew as her sensei suddenly turned into a blonde woman. Grey goop melted from the body, a result of this lady's quirk. Iris internally groaned that she fell for a shape shifting styled quirk. "I've wanted to meet my niece for so long! You can call me Aunt Toga, or Aunt Himiko, or whatever you want!", the giddy girl exclaimed.

Another realization suddenly dawned on poor Iris, the revelation of the relationship she had with this woman only meant one thing. "What your aunt meant to say.. was that we didn't have a proper introduction the last time.", her uncle covered in burn marks was also present. Dabi revealed his position from the shadows, she was effectively trapped by the villains.

"Come on, Kasai, we can still get out of here! We can beat them!", Iris attempted to create an attack formation with her friend and fellow classmate. When the boy wouldn't budge, when he refused to fight back to back with her, she finally made the connection. "No.. Kasai, please don't tell me..", Iris stumbled away from him in absolute terror.

Kasai stared into the girl's eyes, she had a look of utter betrayal. Before the boy could respond, Himiko leaped in between them with that usual cheerful attitude. "Yep, we're his parents! We had our little Kasai infiltrate U.A with the sole purpose of bringing you here!", she seemed to speak for her son.

Kasai hung his head, almost looking ashamed. "It's true.", was all he managed to add to the statement.

It suddenly made so much sense. All the conversations they had about their fathers and why it had been such a touchy topic for the both of them whirled around her mind. Kasai's interest in Shoto Todoroki, it all felt like an elaborate ploy now. Even the boy's quirk was a sinister creation between the two villains, Toga's blood type and Dabi's fire side made a destruction combination. Igniter Fluid, he could burn through DNA like gasoline.

"He was the one that gave us the information on the U.S.J. That was only one of the many times he failed to extract you. After so many chances being squandered, I lost my patience. Having Hypno brainwash the Nagaidesu boy was of my own behalf.", Dabi added fuel to the fire in the young Todoroki's heart.

"This whole time.. you were trying to use me as a bait to get my father? Or what, kill me?", Iris felt like she was buried in despair.

"It started that way.. but as I got to know you, I learned we have so much in common! You understand what your father is and the vigilante, the truths between heroes and villains, how they're all labels. I vouched for you, please, you can be apart of something greater like you wanted.", Kasai spoke up before his parents could say anything. His look showed genuine passion, but only through one eye. The scarred side looked like something more sinister, it glared like Dabi's expression and Iris knew better than to accept the offer.

"She'll never join you!", Shoto Todoroki spoke for his daughter while creating a barrier of fire between her and the villains. "I knew there was something off about Midoriya, I should have figured it was you.. Toga.", the half & half hero stood in front of Iris in a protective manner.

"He followed you?!", Dabi's hands fumed with his anger at Himiko.

"Don't be like that, babe, think of it as a family reunion!", Toga exclaimed.

Kasai felt the eyes of Shoto & Iris on him, the other two were drowned out by the inferno. "Iris, run!", Shoto ushered his daughter out the door and sealed it with ice. Kasai was about to pursue her, but ended up being pulled away by his own parent.

"Come on, Kasai, your dad has a few things to work out with your Uncle Shoto!", Toga giggled while dragging her son away from the inevitable battle.

Dabi stepped through the barrier his brother had created, unharmed by the flames.

"Shoto."

"Touya..?"

It was years before Touya was left in the fire to die by his own father. It was a simpler time, with two brothers curled up on a couch watching a movie together. The film was essentially a ripoff of America's 'The Lion King', but Shoto was too young to mind. The young boy looked to his older brother with a question in bound.

"What is it, Shoto?", Touya raised a curious eyebrow.

"What's a.. d- daa, da-", the young boy had trouble pronouncing the word.

"A daddy?", Touya guessed what Shoto meant to say. The younger brother nodded in confirmation. Touya sighed, he expected as much. The film was about fatherly love, something Endeavor never showed any of his children. "A daddy is someone that.. cares for his kids, like, really cares. He spends time with them and wants to make them happy.", Touya did his best to describe the definition despite their own father being far from it.

Shoto looked to the side for a moment, as if he was pondering what his older brother told him. Touya worried that the boy would realize what Endeavor failed to be. When Shoto looked back, he had a small smile. "Then, you're kinda like my da- daa- Dabi.", the young boy pronounced the title wrong in an adorable manner.

Touya felt his heart clench. He was supposed to be this boy's older brother, not his father.

That didn't stop him from accepting the name though.

Shoto stood across from his older brother. It had been a long time since the two last saw eachother.

Touya said his brother's name again, but this time, without any resentment held.

"Shoto.."

The number one hero stared the number one villain in the eye before responding.

"Dabi.."

…

END CHAPTER FOURTEEN

AUTHOR'S NOTES:

Sorry for the wait! I hope it was worth it.

So, that's the last of Dabi's origin. Next chapter will be the conclusion of that story arc, the fated battle between brothers!

On another note, I recently released a new story! Another quirkless version of Izuku Midoriya, but this one is a villain! If you haven't already, I'd appreciate it if you checked that out! It's called 'World So Cold'.

That being said.. ONTO REVIEWS!

Sunshine's Armageddon:

I think I've said this before, but I agree, this version of Bakugo is probably the hardest I've written. I want to keep the 'same ol Kacchan', but also show how much he's grown with age. Sorta like I did with Izuku and his stuttering/murmuring. Hopefully I can manage to keep that up for as long as that arc goes.

patrickthenobleman:

That is actually a MUCH better codename than the one I went with. I should have asked you all what to choose like I did with Izuku's vigilante alias. However, I think you may find some comfort in knowing Omo Hatsu Satsujin roughly translates to Lord Explosion Murder. I just took the Baku part out of Bakuhatsu, which means that's pronounced 'splosion', which makes it ten times better.

As for the family interactions, I love writing those. Especially the Todorokis, Tokoyamis, and Midoriyas. I have to find a way to work more of that in! Especially when it comes to confrontations!

purpleflowers10:

Yeah, I do apologize for the somewhat shorter chapters, it's surprisingly hard to get a high word limit. I try and aim for 5,000 at the least, but sometimes settle for around 4,000.

As for Kasai's and Iris's relationship, I love a fire & ice romance, but they are unfortunately cousins. I don't want to implore incest, they never really kissed or anything, so those feelings could be considered a confusion for brotherly/sisterly love. We'll see!

Jadegem02:

I'm happy that reveal came as a surprise for some readers! It was like Tobi in Naruto, I desperately made up lies and excuses to hide his somewhat obvious identity when my friends watched it haha!

As for the internships and Bakugo, there wasn't too much this chapter, but I can probably fit in some good stuff in the next as I close out the arc!

Guest:

I hope you'll love this as much as I do: Omo Hatsu Satsujin roughly translates to Lord Explosion Murder. A lot of the names I pick out have literal or comedic translations, so feel free to ask or search them up!

Ooobserver:

I'm glad I could stump you with another cliffhanger, those are my pride and joy! There's plenty more of those to come, so get ready!

Before I close out this chapter, I want to thank you all for over 100 followers and favorites! You're the best!

Hope to see you next time!
