He was sure he'd get a day. One damn day before the hellion descended, but it would seem Katsuki was shit out of luck, because around midday, with the rest of 1-A gone to training and him watching a movie with Atem, the doors burst inward and in stomped his irate sire, steam practically pouring from her nostrils. Atem leaped out of his skin, scrambling off the couch and eyes wide.

"Damn it, Hag!" Katsuki exploded. "Did no one teach you how to open a damn door?!"

"Watch it brat!" The infuriated blonde bellowed back.

Atem startled gaze slipping toward the other male Omega waiting with a patient smile and unsure of what was about to happen. He recognised the pair as Katsuki's parents Mitsuki and Masaru Bakugo, but he wasn't sure how to deal with all the heightened emotions. After several seconds relief flooded him when the tension broke and Mitsuki gathered Katsuki against her. Shuddering a breath, Katsuki nuzzled into the familiar scent of his Alpha parent, letting out a soft pup like huff when the quiet Omega joined in.

Eventually they broke apart, Mitsuki's red eyes zeroing in on Atem. "So…What Nezu told us is true."

Protectively, Atem wrapped an arm about his middle. Anubis stood behind him, rumbling a growl, fully intent on protecting him.

"Damn it, Hag!" Katsuki blustered angrily. "You're scaring him." Going to his wary mate, Katsuki pulled him close and bent his head whispering in his ear, loving how Atem softened against him. When he tensed again, Katsuki let out a warning growl.

"Easy," Mitsuki urged as she approached, watching her tone this time. "He's not in danger Katsuki…Let him scent us."

With some nudging, Katsuki coaxed Atem into scenting his parents and once Atem's Omega was satisfied, they were safe, he relaxed.

Mitsuki smiled. "There now…What's your name then?"

"Atem," he introduced. "My name is Atem Yagi."

"So that's true too," Mitsuki commented. "You're All Might's pup."

Atem nodded, setting a hand on Anubis' large head when the fire panther continued to snarl. Mitsuki grinned at the animal, purposefully flashing her Alpha fangs, but it did little to deter Anubis.

"Did Nezu just blurt out everything?" Katsuki asked, incredulous.

Mitsuki turned to usher Masaru to the couch, before taking a seat and pinning Katsuki with a stern look. "So…A pup."

Katsuki crossed his arms, staring her down. "Please do not hold us responsible for that. We were locked up by lunatics, hoping to breed All Might's Quirk."

"Yeah, but you're still giving them what they want."

Stomach dropping, Katsuki didn't like where this was going. He loved his sire, but it was moments like this where for just a moment, he honestly hated her. "They were caught." He ground out. "The people involved will never see the light of day again. What we make of it now, is our choice…our business."

"So, you're going to sacrifice all you've worked for?" Mitsuki questioned. "Plenty of time for pups, Katsuki."

Every inch of Atem's insides ran cold. She was attempting to convince Katsuki into ending the pregnancy?! Omega laws had come quite far in recent years, but the choice to carry a pup to term, unfortunately, still remained with the Alpha so long as they were mated. If Katsuki forced it, he had no choice but to comply.

"This is what you came here for?" Katsuki snapped. "Heaven, forbid you give a shit I've been held captive for several days!"

"Watch it brat! Of course, I care, but there is the very pressing issue of a pup at only sixteen years old!"

So caught up in their argument, neither noticed Atem leaving. Out in the fresh air of the UA grounds, the Omega scrubbed at his damp eyes and picked a random direction. Anywhere was better than caught between two Alphas tossing testosterone and personally, he wasn't in the mood to listen to Mitsuki convince her son to abort his baby.

Hearing shouts, Atem followed the sounds, curious. He came upon 1-A out doing a training session, with Aizawa barking commands. It was fascinating to watch so many Quirks in action. Anubis sauntered next to him, the fiery cat keeping a watch. He noticed Mineta sat sulking on the sidelines, while Iida dodged attacks from Ojiro. He had made a point to learn all their names.

"Atem?"

Jumping, Atem glanced over, watching Izuku approach, with Mina at his back, the two Omega studying him curiously. "Oh, hello, I hope I'm not interrupting."

"You're not," Mina said with a smile, noticing Atem's agitation. "Hey, you, okay? Did Bakubabe say something he shouldn't have? You know Alphas, total knot heads."

Atem shook his head. "Eh…No…Nothing Katsuki said. His parents are here. Personally, I don't think his sire is overly fond of me or our…um…situation."

Izuku frowned. "She has an issue with the pup?"

"She…She would rather we end the pregnancy."

"WHAT?!"

Livid didn't begin to cover how Izuku or Mina were taking that. As Omegas, they understood just how protective Atem's instincts had to be riding, so to hear anyone suggest termination in front of the Omega infuriated them both.

"MR AIZAWA!" Mina hollered. "WE'LL BE RIGHT BACK!"

"What? Where are you going…hey!"

A little stunned, Atem just followed the pair, trading curious glances with Anubis as they made their way back to the 1-A dorms. The discussion had escalated to full blown roaring and was obviously loud enough to draw attention.

"Mama?" Atem questioned, catching sight of Toshinori approaching, with Enji in tow. Not that he acknowledged his sire…personally he wasn't sure how to contend with the Alpha.

"Atem!" Toshinori rushed out with relief. "I was heading over here with Enji and heard shouting …What on Earth is going on?"

"Kacchan's sire," Izuku began with disgust. "She's trying to convince Katsuki to end the pregnancy."

"She what?!" Enji barked, teal blue eyes narrowing in temper. "She has no right to force that on either of them!"

"SCREW YOU HAG!"

Toshinori jumped at Katsuki's sudden howl of rage and Atem stumbled, dropping to his knees with a grunt when his Alpha's pheromones exploded from the dorms, driving him to submit. The other Omegas were quick to follow, instinct forcing them to.

"Sweet hell!" Enji choked, finding it hard himself to stay upright. "I've never felt an Alpha that strong!"

"Make him stop, Enji!" Toshinori hissed out. "Before he has every Omega in the school on their ass!"

Nodding, Enji made his legs move. It was like walking through sand! Katsuki's enraged pheromones slamming against him, doing everything to drive him back. He heard of Alphas so in tuned to their instincts, they were on a different level, but he had never encountered one. Their Alpha traits were superior in every aspect and other Alphas could not challenge them. They were known as a Prime Alpha and were rarer even than a male Omega.

Truthfully, it was the only reason his sire hadn't already forced him down. The fact is, she couldn't.

"This is stupid, Katsuki!" Mitsuki raged, red eyes livid. "Do you think you can be the best chasing after a pup? Think the young of All Might himself is going to sit home and knit booties?!"

"You both made it work!" Katsuki snapped. "You raised me!"

"Because I had no choice!"

The sudden silence after that little confession was nearly deafening. Katsuki snorted, arms crossing. "You know, I should be surprised by that, but I'm not really."

Masaru looked up from where he was on the ground, shoved down by his son's and mate's pheromones. "Kats…She didn't—"

"Mama, don't…Just this once, please don't defend her bullshit." Shaking his head, Katsuki set disgusted eyes on his sire. "You know. I told my mate how you two met. Romanticised it a little. But truthfully, you got your dick wet, and I was the consequence."

"Oh, don't be so dramatic, brat," Mitsuki sneered.

"I'm emancipated."

Mitsuki jerked as if slapped. "Excuse me? The hell you are!"

"It's the law, hag!" Katsuki snarled in response. "A mated Alpha is automatically emancipated if under eighteen! You've no say in my life, my mate's, or our unborn pup's!"

"Alright, that's enough!" Enji barked, having heard plenty. "Bakugo, pull your Pheromones back before you cause your mate anymore discomfort…Mrs Bakugo…What they decide is nothing to do with you. I think it's time you left."

Seething, Mitsuki glowered up at Enji. "And what's it to do with you, Endeavour?!"

Enji sneered. "Yes, that little sliver hasn't gotten around yet. I am Atem's sire, and I am here to tell you, to back off, you're distressing my pup!"

Mitsuki startled. "What? That's a lie!"

"Actually, it isn't." Atem said, managing to finally drag himself off the ground outside. "Endeavour is my father and he's right. It's time you left."

Snarling, but realising she was cornered, Mitsuki barked at Masaru to follow her, and the couple left, doors slamming behind them. Atem sagged, catching himself against the couch. He chuckled when Katsuki, Toshinori and Enji surrounded him.

"I'm fine! Katsuki's pheromones just left me a little bit shaky."

"Shit! Sorry, baby," Katsuki apologised, tugging him close and letting his scent wash over Atem, calmer now. The Omega shuddered with relief. "Better?"

"Much." Atem pulled back, gesturing toward Izuku and Mina who stood in the doorway. "I went for a walk. Bumped in to Izuku and Mina. I wasn't in the mood to listen to your sire convince you I should abort."

Katsuki chuckled. "That old hag wasn't going to convince me of anything and thanks to the law, she'll never have a say again."

"We'll get her blocked from the campus," Toshinori promised. "We were coming to see if you'd like to come to dinner at Enji's. He wants you to meet your other siblings."

Atem blinked in surprise, looking up at Enji. "Your wife knows?"

Enji winced. "In honesty…She always knew about me tending to Toshi's heat…but no…she doesn't know about you and right now is not the best time with her in hospital. I told your other siblings…Your sister Fuyumi is excited. Natsuo is angry, but he'll come around. He's always angry at me. This is just something else."

Atem rubbed his arm, shuffling on his feet. "I-I don't know. Shoto doesn't seem terribly fond of me, and I don't want to create any more upset."

"You won't!" Enji reassured him hastily, determined to get to know his youngest. "None of this is your fault, Atem. It's going to be okay. But I won't force you."

In the end, they came to a compromise. He'd go, but only if Katsuki could come with him. He wasn't going anywhere without his mate. Since he had nothing to wear, or possessed anything really, Atem borrowed some clothing, his mother promising to take him shopping first thing in the morning. Unfortunately, because he was so tiny, Jiro's clothing was the only thing that fit him.

"Do I look okay?"

Sat waiting in the common room with Icy-Hot and Deku, Katsuki glanced over, and his jaw dropped. Atem would have been gorgeous in a paper bag, but in clothing that fit, he was positively mouthwatering.

Courtesy of Jiro he wore black skinny jeans that hugged every inch of him. A plain black t-shirt fell to his hips, and she had lent him a bright red leather jacket that fell to mid-thigh. He was even wearing leather boots with a low heel and his hair had been tied up, falling in a thick tail of black and red, the sunny blonde framing his face.

"You're perfect," Katsuki said with a sultry growl, prowling toward him, dipping his head, he nipped at the mating bite on Atem's neck.

Atem arched with a purr, snuggling into Katsuki's warmth. Laughing when his mate began kissing along his shoulder blade. "We have to go, Katsuki."

Groaning, Katsuki pulled back, pressing a last kiss to his mouth. "Alright Icy-Hot, Deku! Let's get going!"

Atem blinked. "You're coming, Izuku?"

Izuku flushed. "Um…Yeah…Shoto and I are sort of…uh…together."

"That's wonderful!" Atem grinned cheerfully. "You're perfect for each other!"

Shoto smiled a little. It was taking him time to get used to his brother and he was coming to terms with the fact, the younger boy wasn't at fault. Hell, his father wasn't even at fault and there was something extremely sweet about the boy. Yet, fierce. Shoto felt given time, his brother would be a hell of a powerhouse. Speaking of… Anubis joined them, the panther sticking close to his master and as a group, they headed out.
