Katsuki doesn't know how he got here. Really, he doesn't. Sitting right across from Izuku's father, who is staring daggers into him while he awkwardly stares back. Izuku, like the naive little mother fucker he is, flutters around in the kitchen, unaware of the brewing tension.
Katsuki gulps, throat was dry and full of cotton, carefully picking up the water glass with two fingers, making sure not to shatter it, and throws the water back quickly. Placing the glass back down, Hisashi crosses his arms, glare digging into Katsuki. "So, Bakugou-san? How'd you meet my son?"
Fuck you, Izuku.
Fuck you.

Earlier.
Izuku stares up at Katsuki with glittery eyes, a smile on his face. Katsuki narrows his eyes, tail twitching slightly, large hand smoothing up and down Izuku's back. Izuku continues to stare, unblinking, his second eyelid sliding out to keep his eyes from drying up, keeping his stare on Katsuki. Neither of them break the tension or silent staring contest, settling on staring at each other for the time being. Katsuki finally breaks, sighing heavily, seeming to deflate a bit. "..what do you want, you little heathen?" Katsuki mutters as Izuku pushes up slightly, eyes glowing with something devious, and Katsuki regrets talking.
God damnit.
"Kacchan! Meet my dad!"
..what?
Katsuki blinks, then blinks again, then blinks aga-
"What?" Katsuki asks, narrowed eyes staring down at Izuku, who smiles brightly, and Katsuki has to force himself not to look away. It's like staring at heavens (overly) shiny gate without sunglasses. "Repeat that again, slower," So I can make sure I'm hearing this shit right, Katsuki muses in his head as Izuku's tail swishes and wags like an excitable puppy.
"Meet my dad, Kacchan! Come over for dinner! Maybe you can also meet my class!"
Oh. So his ears weren't playing tricks on him.
(Why. Why him? Sure, he loves his boyfriend, but why him. He's a Demon Lord; for god's sake, he shouldn't be scared!
WHY IS HE SHAKING???)
"Sure."
Oh my god, he's a fucking dumbass.
"Yay!"
As long as Izuku is happy, he'll suffer.
It's not like Izuku's dad is scary?

Okay, he redacts that statement, Izuku's father, Hisashi, looks two seconds from hopping the table and strangling him. Even though he's nine feet tall, could smite the entirety of Japan out of existence, has thousands of blood-thirsty demons at the tip of his fingers, he's nearly shaking in his boots, feeling like he's back to being four years old as his Sire, the previous Demon King, or well, Queen for his mother, scolds him for tracking dirt through their precious castle.
(It's been thousands of years since that day, but it still feels like he's been slapped into the past.) Katsuki holds Hisashi's stare, making sure his body isn't shaking, but internally, alarm bells continue to ring, his mini-me inside his head screaming, ready to make a swift escape. So what if it looks cowardly to escape to hell if Hisashi tries to murder him? It doesn't matter if he could escape with his life.
Izuku flutters and flits around the kitchen, humming softly, tail swishing and twirling as Izuku bounces on the balls of his feet, a nervous but small smile on his face. He hopes papa and Kacchan get along! He swirls the mapo tofu around, making sure it's spicy enough till he's coughing up spurts of fire. Perfect! Katsudon is placed in bowls and the mapo tofu (one dish for Katsuki that would cauterize the innards of a human) and one mild for his dad.
Izuku uses his tail to hold his bowl of Katsudon as he walks out, humming as Hisashi's entire body changes, from protective dad to happy, soft father, imaginary sparkles, and soft pink bubbles flitting around Hisashi as he grabs the mild dish of mapo tofu from Izuku. Katsuki uses his hand to grab Izuku's katsudon bowl, placing it in front of Izuku's seat as he nearly drools at the sight of the red-hot mapo tofu that Izuku made for him. Giving a low, happy croon and a small kiss on the cheek to Izuku, who smiles and nearly glows. Hisashi's eyes narrow, and he glares at Katsuki, who sweats nervously before returning to his sparkly self, thanking and praising Izuku.
-
So, Hisashi sits across from a demon lord, who looks very awkward and seems to wilt under his firey stare. He knows who this bastard is. He was tasked to keep the book for a mission, and if needed, they'd summon the bastard. Luckily, they never needed the book because, well, it was gone. And now he realizes that Izuku must have gotten ahold of the book and summoned him. This is a mess of a mess. After dinner, which was very good, Hisashi places his elbows on the table, resting his chin on his intertwined hands, shooting another nasty glare at the Demon Lord, making the man stiffen. Hisashi can see Izuku's soft tail intertwine with Katsuki's dragon-like tail, winding together.
Hisashi continues to keep his glare on the demon lord, uncaring of his and his son's intertwined tails. Hisashi clears his throat, making Katsuki stiffen (it's very odd and mildly amusing to have this power over a Demon Lord who could kill him with the snap of his fingers. Guess that's his dad power,) and Izuku trill softly, looking up at his father. Hisashi leans forward, making Katsuki lean back, eyes switching from Izuku to Hisashi. "Eyes here, boy," Hisashi speaks, pointing to his eyes as Katsuki nods swiftly, looking Hisashi in the eyes. Not even going through awkward small talk, he cuts to the chase, asking very straightforward, dry questions. "When did you meet my son?" "Six, he summoned me on accident."
Ok- wait, WHAT- Hisashi keeps cool, "What are your intentions with my son?" Izuku groans as he slams his head into the table. Without looking, Katsuki catches his head in his hand before Izuku's head makes contact, not even looking, "I intend to cherish your son for all of eternity, and I plan, with your and his consent, to make him my queen of hell. But that is for the future; right now, I plan to be a good boyfriend for your son." Hisashi nods, eyes flitting over to Izuku, who's now beet red, steam hissing off his pointed ears, and Hisashi's glare softens just the tiniest bit for a moment, making Katsuki's shoulders relax momentarily before Hisashi's glare gets more heat behind it, making the blond tense, all the scales on his tail puffing. "So, let me get this straight, my son does not have a quirk? It is not a mutation of my quirk?"
Hisashi asks, not even acknowledging the tiny tinge of disappointment in his tone. "Yes, sir, he had demonic powers I gave him when he asked me to protect him. It was a demonic deal with my seal on it, but it was not out of malicious intent. If you think that after I have done my duties to protect him, I eat his soul, you are mistaken. My deal shall be there for eternity and will never waver. It is a one-way deal, for I gain nothing from it." Katsuki speaks the truth and nothing but the truth.
It was a one-sided deal that usually, no demon, even himself, would participate in. But he does not want to feast on Izuku's pure soul, even though it may make his mouth water with temptation, but he will do his duty to protect Izuku. Izuku's ears twitch as Hisashi's brows furrow, eyes glancing over to Izuku, who is still beet red, head buried in Katsuki's large palm.
"Is he a half-demon?" He asks, turning to the Demon Lord, who shakes his head. "My powers were potent enough to turn him into a demon fully. If he were quirked, he would have been turned into a half-demon, but his body latched onto my powers and turned him into a full demon." Katsuki explains, thumb caressing Izuku's head, making the teen purr slowly, leaning into the touch as Katsuki takes his palm out from under Izuku's head when he pulls his head up.
Hisashi nods, seeing that Katsuki has no ill intent towards his son, and sighs. "Okay, you two seem happy. But, Bakugou-kun, even though you may be a demon lord, I will hunt you down, drop you in the largest vat of holy water I can buy, and leave you there to writhe if you dare to hurt my son. Got it?" Katsuki's eyes are blown wide as he nods fervently, making a dull shudder travel up his body. Scary. Izuku snickers at the look on Katsuki's face as the awkward tension is broken, and they all slip into easy conversation, Hisashi and Katsuki talking about many things, and Katsuki retells funny tales from hell.
It's domestic.
-
What's not domestic is Aizawa choking out his boyfriend with his capture weapon, glaring at him with the full intent to kill. While Kastuki sits there, slowly losing blood circulation to his head, hands twitching and eyes wide as Izuku sits off to the side, while Katsuki is throwing pleading glances at his beloved little boyfriend. Aizawa threatens the same threat as Hisashi did if he as much touched a hair on his problem child's head, while Katsuki started to look blue.
Katsuki's hands twitch as he chokes, unable to rip the capture weapon off his throat, knowing Aizawa would slaughter him with a holy weapon he confiscated from his student. (Tokoyami. It was Tokoyami.) Izuku starts to fret, and instincts kicked in, his claws slicing through Aizawa's capture weapon to relieve the pressure around Katsuki's neck, allowing blood and air to come through while the blond collapses on his back. "Does everyone you- cough - meet swear death for you? Jesus Izuku-" Katsuki whines, rubbing his throat, the bruises left from the capture weapon fading away.
"Yeah, pretty much."
"Fuck."
-
When Katsuki meets the class, Tokoyami screams and fires off question after question. Luckily, he's known Izuku for nine years, and Izuku's mumbling is much faster than the rapid questions. Luckily he can answer them at the same pace they're coming. After the rapid questions are done, Tokoyami faints, and Shoji catches him.
The rest of the class is pretty chill and seems to really get along with Katsuki, who spits insults out every two seconds, but that's different.
It's a good day.
(Katsuki quietly continues to think as Aizawa glares at him,
why him?)
