Chapter 13: A Game of Conquest

Tomura awakens from another long sleep after having returned to his master's palace after encountering the successor. His pale eyes stare dully at the pink ceiling of throbbing flesh. Despite the pink, the red, and the black, it is only the color green that sticks in his mind. Green eyes in particular, which have haunted him since falling back to sleep. And now, waking up again, the ceiling stares back at him.

'He looked at me with those same green eyes…' Tomura sits up. 'No. They were not the same. The same color of green, yes, but not that look.'

"Finally awake?" All For One enters Tomura's room. "You slept for a few days, as to be expected. You're still awakening from eons of slumber. One cannot have too much excitement all at once without exhausting himself," All For One walks closer to Tomura's bed, finding it odd that the young demon was not responding to him. "My dear Tomura, are you well?"

"Master?" Tomura senses All For One's presence and glances tiredly up at him.

"Yes, it is I," All For One reaches out a large hand to place atop of Tomura's head. "My chosen one; my son and my heir; something is bothering you, and I must know what it is,"

"...green eyes…"

"...what about 'green eyes'?"

Tomura sits still, staring at his cracked, dry, and pale hands, both of which flash with the images of green eyes. "They haunt me…" he whispers, ignoring the slight pain in his dry bottom lip as it cracks when he speaks.

All For One walks around the bed, which sits in the center of a large, enemy room. "Tell me...what do you remember?"

"...a vast green field...dotted with colors...they flutter on the breeze…"

"The human realm," All For One states for him.

Tomura blinks slowly, his fingers twitching. "Warm air...bright sun...a stream…"

"Go on?"

"...and a person." Tomura's mind conjures the blurred image of someone slowly standing up from having dipped their hands in the stream. A pair of calm, friendly green eyes look upon him, he remembers, without fear. "A familiar person…" Tomura turns to All For One. "Master, who is he? Who do those green eyes belong to? I thought I knew...when I was exploring the wood."

All For One is silent for a moment, then places his hand once again on Tomura's head, stroking the pale blue hair. "The successor," he answers. "The successor to The Symbol of Peace; an omega."

Tomura's eyes slowly widen. "Successor…? Omega…? Yes, I...I recall-"

"What do you recall?"

"I see those green eyes...they haunt me...and yet…"

All For One's hand slightly tightens its hold in Tomura's hair. "Speak, Tomura."

"They don't look upon me with favor...only hate."

All For One grins. "Ah, yes, there is a reason for that, my boy,"

Tomura's gaze slowly turns to his master. "What is the reason, master?"

"The omega successor touched many hearts, just as the Symbol of Peace did before him," All For One explains. "He had a magnificent court of powerful and influential heroes of the realm after the Symbol of Peace chose to retire."

"...his court?" Tomura repeats, conjuring another image of a circular table with many seated at it, and the successor's green eyes peering at him. "Yes, his court. I couldn't get near him…"

"They wouldn't let you," All For One gets up and stands at the foot of Tomura's bed. "No demon could touch such a divine and holy spirit as the successor; an omega of pure heart and body with nothing but power following through his veins and loved by all. Borrowed power, of course. It was not his. No omega has ever held That Power before; the power of Light and Peace."

Tomura stares at All For One and says, "I wanted him,"

"You did, but he denied you that chance," All For One taps the footboard with his index finger. "Does that...strike any other memories?"

Tomura grips the sheets. "There was another. A human alpha…"

"Yes. Go on,"

"His eyes were red...but he was not a demon...he fought like one...and...and…" Tomura clutches his hands to his face. "I can't remember!"

All For One decides to tell him the truth, as it would help to awaken Tomura's still sleeping power. "The omega successor chose a demon-like human to be his mate rather than you, an actual demon alpha. He betrayed you. But, can you blame the successor? Why would he want a demon of the Dark World, a race he is sworn to defeat and wipe from the face of the earth, as a mate? He may have been the successor, but in the end, he was still an omega looking for the best alpha. Appearances play a large part in an omega's desire to choose an alpha, and you were not up to his standards, and it made you very, very angry."

Tomura starts to growl, ripping the bedsheets little by little.

"He didn't want you. He never wanted you. And when you learned of who he chose, your power exploded, and we attacked." All For One grins. "Oh, what a fine time that was! So much destruction! The Symbol of Peace was gone! The world was ours for the taking!"

"And yet…we are here...in the bowels of the earth,"

"Those green eyes you see are how he looked at you after the transformation of his alpha mate."

Tomura lets go of the sheets to look at his hands and began to remember attacking someone, turning them into a demon. It was the alpha human, the one the successor chose. "I remember now," Tomura says in a whisper. "I remember...turning him to our side…"

"And why did you do that? Can you tell me?" All For One knew the answer already.

"If Izuku was going to love Bakugo, a demon-like human, and repulsed by anything that wasn't human...then I would make what he loved the most into what he detested the most. A demon like me!"

"And I took the human's heart!" All For One can recall that day, standing over Bakugo's changing form, watching the human squirm before reaching into the alpha's chest and ripping out the heart, claiming it as his own. "Chaos reigned after that moment, and it will reign again! Only this time, WE will be in control! WE'LL control the successor! WE'LL control his child! WE will destroy Izuku's court as we did before, and crush Bakugo beneath our might!"

Tomura's lips crack as they turn into a grin.

"You will have your green-eyed omega, and we will reign over both worlds for all eternity! We have their hearts! We have their memories! The power is ours this time, Tomura!"


Izuku is dressed comfortably and sitting in front of the fireplace, waiting for Bakugo to come. Iida had the 'new diet' meal sent up to Izuku, but he just couldn't stomach the food on the plate. Bakugo will likely scold him for not eating, but demon food isn't something Izuku wants to dine on. The plate sits, untouched, on the table beside their bed. Most of it was demon realm vegetables and fruits, but again, they didn't look appetizing. Especially that thin slab of strange meat that might be some sort of tongue or liver of a creature.

He gets excited when he senses Bakugo nearing and the chamber doors open. Izuku smiles at Bakugo, his husband and mate, while the rest of his body craves the alpha's touch.

"You look livelier," Bakugo says.

"Yes, I got some good rest, and Tokoyami's medicines work very well! The bites healed quickly."

Bakugo notices the food on the table. "Why haven't you eaten?"

"I can't eat that," Izuku answers. "It looks terrible to me. That's Iida's special diet plan for me for the pregnancy."

Bakugo narrows his eyes at Izuku. "You need to eat this diet. If you can't eat it, I can have it made into a stew or a drink. Would that be easier?"

Izuku thought for a moment, then nods. Bakugo is being resourceful rather than simply yelling at him to eat the food. "Yes. So long as I don't have to chew anything," he goes over to join Bakugo at the bed. "What is this stuff anyway?"

"It's best you don't know," Bakugo flicks Izuku's nose. "You're a Dom-Omega of a powerful Blood Lord alpha demon and pregnant. You need to have foods that are known to give strength, energy, and health to a growing fetus. I'm expecting an alpha child," Bakugo tells him. "And this diet will help to ensure that it is born alpha and an alpha male at that." Izuku frowns at him, and Bakugo rolls his eyes. "What?"

"What's wrong with the child being born a girl or an omega? Or even a beta for that matter? We spoke of this before. Our child's purpose remains the same regardless of gender or body. Do you think the other Blood Lords will mock you for not having an alpha heir?"

"Not liking your tone, Deku," Bakugo warns him, gently slapping the omega's leg with his tail. "I'm certain it's an alpha because I doubt my cock and seed would produce anything but alpha children,"

It was Izuku's turn to roll his eyes.

"However, this isn't just 'some' child you're bearing; it's the child that will break the barrier between the worlds. I'm not taking any chances," 'And with the change in plans, an alpha child is needed.' He says to himself.

"If you have no doubt in your...abilities as an alpha...why should I have this fancy diet?"

Bakugo scoffs and crosses his arms. "There's the fact that you're a human and we don't know how well a human can carry a demon child. We're taking all the precautions." He pinches Izuku's lips together when the omega was going to speak, most likely to contradict him. "I thought we were spending the evening together doing...I don't know...mate stuff. Not debating over these political matters," Despite the news and excitement that he's come to learn, taking a break from it for the night was a refreshing thought.

Izuku gently pushes Bakugo's hand away. "You're right. I don't think I know what 'mate stuff' is, either. I just want to spend time with you."

"Do you like games?" Bakugo asks him.

"I guess that depends on what they are?"

Bakugo leaves his side to go into one of the wardrobes and takes out a wooden box. He brings it over to the small table by the fire. "I'll teach you how to play 'Conquest',"

Izuku tilts his head as Bakugo sets up a checkerboard and starts lining pieces of two different colors at opposite ends. One side is red, and the other is black. Izuku reaches out to pick up one of the pieces, noting how they are all different from one another, yet the pieces mirror each other.

"It's a game of war," Bakugo tells him. "Pick a color."

"A color? Oh! Um, I guess I'll take red?"

Bakugo nods. "The losing color. Good choice."

Izuku sits on his side and Bakugo on the other. "Is that why you don't like to choose red? Because you'll lose?"

Bakugo sneers at Deku's taunting. "I never lose. No one has ever beaten me in a game of Conquest."

Izuku glances up from studying the board and says, "I wonder if you only win because of who you are, and your temper."

"Excuse me?" Bakugo growls at him.

"Well, you ARE a Blood Lord, the Flame Lord, the Alpha Prime with a fierce reputation and even fiercer temper. Maybe people are afraid to let you lose to them because you'll get angry if you don't win." He wouldn't put it past Bakugo punching someone in the face for beating him at a game.

Bakugo is silent for a moment, then throws his head back and laughs maniacally. "Oho, are you in for it now,"

"I'm a fast learner," Izuku tells him. "I won't lose to you, Kacchan." he smiles gently and says, "Shall we, then?"

Bakugo couldn't believe it; everything Deku said was right. Deku learned how to play quickly, and well, by the third round. Then, on the fifth round, Bakugo experienced defeat for the first time as Deku's queen piece takes his king piece. He never saw the finishing move coming! How could he have missed it? He kept looking over the board of pieces to try and find where he went wrong.

"Oh, look at that," Izuku points out his win. "I guess we can't say that red is the losing color any longer."

"Pfft! Beginners' luck!" Bakugo says. "Another game!"

By the eighth game he won, Izuku was terribly tired and couldn't stand to play another round. He had beaten Bakugo each time, amused at the demon's sore loser ranting and demanding to play again. "Kacchan, I'm very tired and I need to sleep,"

"No! Another game! Right now! I'll kill you if you don't play!"

Izuku gets up from the chair. "Maybe tomorrow," He goes to a seething Bakugo and gently kisses the demon's temple. "Come to bed with me?"

"No! Not until I figure out how you keep winning!"

Izuku just shakes his head, leaving Bakugo to his seething and gets ready for bed. He almost falls fast asleep the second his cheek hits the pillow, but stays awake to enjoy the whispered mutters and rants of his mate a little while longer. Bakugo is, without knowing it, showing Izuku his sensitive side. Never once, after each defeat of Conquest, did Bakugo physically try to attack or hurt him. Verbally, yes. But not physically. Perhaps, if Izuku had been anyone else, his nose, jaw, and neck would be broken, or he'd be burned to a crisp.

When Izuku wakes up, it's to the clenching pain in his stomach. He rubs the small bump, trying to soothe whatever is happening in there. It eventually forces him out of bed, attempting to use the water closet in hopes of relieving the pain. No such luck. The pain is still manageable, but just uncomfortable. Izuku can go about the day normally if he needs too. Then he sees Bakugo asleep at the game table. He giggles softly and approaches his mate, placing two hands on Bakugo's shoulders. The demon mumbles something, and Izuku kisses the sensitive spot at the base of Bakugo's left horn. The mumbles turned into a purr, making Izuku's heart swell with joy and the pain to leave his belly. He wants to hear more purrs from Bakugo, so he kisses the base of the other horn. Success! Izuku then brings his hands to massage the horns, pulling a deep groan from Bakugo's throat that wakes the alpha up.

"Good morning, Kacchan!" Izuku chuckles as Bakugo mutters something incoherent but his demon tail is wagging like a dog's. After Bakugo's defeat last night, the least Izuku can do is make his husband feel good physically.

"...grrr...another game!" Bakugo says, now awake.

"No. It's morning and I'm sure you have work to do," Izuku says. "And I would like to NOT be in this room all day. Can I accompany you throughout the day?"

Bakugo sits up and batts Izuku's hands away, letting out a yawn mixed with a little roar. "I'm not letting you get off with winning. You must have cheated!" He grumbles when Izuku's arms wrap around his neck in a tender hug.

"I promise we'll play tonight. So, can I accompany you today?"

"Sure. Whatever. You might as well learn the ways of the castle. And I won't forget tonight! You're going down!"

"Yes, yes, I'm sure of it,"

"Don't patronize me, omega! Stop kissing me! It's annoying!"

Izuku laughs and pulls away. "And yet, you weren't pushing me away at all. I think you like my kisses!"

"They're shit kisses!"

There's a knock on the door and Bakugo shouts for them to enter. It's Tokoyami carrying a tray with a mug and a bowl. In his beak are two pieces of parchment. Izuku rushes over to help, taking the tray from him. They exchange 'good mornings' and then Tokoyami proceeds to explain to Izuku about the tray.

"It was mentioned that you cannot eat the special diet food as is, so it's been made into a porridge for you and sweetened with honey."

"Oh, thank you,"

"And the mug is a special herbal tea and medicine blend that you are to drink every morning to help with any cramping or morning sickness."

Izuku tilts his head. "Morning sickness? Oh, that must be the pain in my stomach that woke me up. Bakugo helped to make it pass!"

"What do you have there, bird-brain?" Bakugo asks, referring to the letters.

"Shoji and I are leaving soon. I need you to sign these. Same as every mating cycle."

Izuku places the tray down on the eating table but takes the tea first instead of the porridge. He joins the two at the game table, watching Bakugo unfold the letters. Tokoyami brings Bakugo a quill and ink. "What are these?" Izuku asks.

"As the Dom-Omega, you need to sign these as well," Bakugo tells him.

Izuku looks to Tokoyami for further clarification.

"These are legal documents that I present to Lord Hawks, the King of the Gargoyles," Tokoyami tells him. "One ensures that I only mate with Shoji, and as a member of Lord Bakugo's territory, Lord Hawks does not have the right to take me as part of the mating harem. The second is, should another alpha gargoyle of high standing challenge Shoji, and something happens, we are not liable for any injury or death that Shoji may cause to them."

Bakugo growls. "I just finished paying off Shoji's last case, by the way," he mentions to Tokoyami.

Izuku sighs. "An omega's word or choice isn't taken seriously then?"

"Not during mating season or a rut," Bakugo says, signing the first document. "Alpha Primes and high ranking lords, like Hawks, have the right to take and mate with as many omegas as they want, whomever they want, regardless of title or rank or mating status. An omega would need the written protection of someone like me, an Alpha Prime, to make their word hold true. And, should these documents be ignored by the other party, I have full rights to punish the other."

Izuku puts his mug down to take the quill. "I see." He looks to Tokoyami and says, "How do you feel about all this?"

Tokoyami shrugs his shoulders. "It is what it is,"

"Hm." Izuku pauses and asks, "Wait, how do I sign this? What name and title should I use?"

"I'll show you," Bakugo gets up to stand behind Izuku and guides his hand in the signature.

Izuku watches the signature appear; Dom-Omega, Mate of Katsuki Bakugo.

"There. Now sign the second," Bakugo says. Izuku hesitates. "Now what?"

"Kacchan, I have a name," Izuku's brows furrow a bit. "I wish to sign these documents with my name."

Bakugo dramatically groans. "Fine! But you need to sign 'Dom-Omega' first,"

Izuku smiles and does just that on the second document. "There."

Bakugo folds the papers and gives them back to Tokoyami. He gives the gargoyle a hard stare, reminding him not to say anything to Hawks. Tokoyami nods in understanding.

"Shoji is aware as well," Tokoyami tell Bakugo, referring to their group meeting yesterday. Bakugo nods silently.

Izuku notices the silent exchange of information between the two and wonders if he should attempt to ask what it's about. However, he figures if he does, they wouldn't tell him anyway.

"Have a safe trip, Tokoyami," Izuku tells him. "I hope you won't be gone long?"

"No," Bakugo answers for him. "Tokoyami and Shoji will be back before you know it,"

"Yes, we won't be long," Tokoyami bows his head to Izuku. "Thank you for your signature. And make sure to eat the porridge and drink that tea."

Izuku chuckles and picks up the cup again. "Don't worry. I promise." After Tokoyami leaves, Izuku turns back to Bakugo. "Kacchan, I thought I was in charge of all the omegas in this castle?"

"You are," Bakugo says. "What's your point?"

"Wouldn't my signature have been enough to protect Tokoyami?"

Bakugo smirks. "For something like that, you need MY signature as well. Omegas under our rule report to you first, and then the matters are transferred to me for further approval. Before you open your mouth to counter, Deku, I'm not finished!" he warns. "Tokoyami is a very important omega here at my castle and therefore a different matter. He is to obey you; that much is true. But for something like the gargoyle mating ceremonies, my signature needs to be on those documents. When dealing with high ranking officials, the word of a Dom-Omega does not hold as much power as an Alpha Prime. Understand?"

Izuku only nods and goes to the table to eat his special porridge and tea. He can hear Bakugo muttering under his breath as the demon demands a kobold to have breakfast sent up. Izuku tries the porridge, finding it to be a bit bland but tasteful enough where it is tolerable. The tea tasted the best, though. He shouldn't be upset over what Bakugo told him, nor should he be surprised. He expects to make changes once they are back in the human realm. And, when their child comes, Izuku will be the one to educate them. There will be time to break that news to Bakugo.

"Okay, listen; I can sense your annoyance and distress from all the way over here. If I was fucking BLIND I would know it! Stupid bond,"

Izuku turns to look at Bakugo. "I'm listening."

"I am behind on a little bit of business concerning people of the territory," 'I have so much more shit to be doing, but I can't leave Deku to do it all by himself. Those other bastards better be working hard!' "We'll see people today, our people, and whenever an omega is involved at the hearing, I'll let you make the decision. Okay? Will that make you stop fucking sulking?"

Izuku smiles and replies, "The fact that you are offering this opportunity to me is more than enough, Kacchan. I guess I'll let you win at Conquest tonight," If all it takes to alter Bakugo's thoughts is some pouting and martyring, then that's what he'll do!

"Oh, you won't have to let me win tonight because I KNOW how to beat you!" he smirks and pounds his fist into his palm. "You're going DOWN!"

Izuku's brows lift. "If that is true, and you figured out how I win...then lets up the stakes a bit. Unless you're afraid?"

"Ha! I'm not afraid of anything! What are the stakes?"

Izuku wants to feel that he has at least some control over Bakugo, and winning at Conquest seems to be, at the moment, the only form of control he has. And, with all the previous omega and alpha mating talk, Izuku, shamefully, thought of an idea. "The loser has to-" he blushes beet red, ashamed of the words he's going to say, but knowing he's only saying them to his mate and husband, the words came out a little easier. "Suck the other off."

Bakugo stares at him, eyes wide with surprise, then he smirks. "I don't suck off anyone," he says. "That's a sign of weakness."

Izuku shrugs his shoulders and returns to his meal to hide his little smirk. "I thought you weren't afraid of anything,"

"I'm not!"

"Then why not accept my challenge," he looks over his shoulder at Bakugo. "Unless you know you'll lose?"

Bakugo's eyes turn black. "Oh...oh you...you little shit…" he growls and bares his teeth, his tail twitching. "Very clever, IZUKU. You have your challenge! When you lose, I won't go easy on that mouth of yours!"

Izuku counters with, "Hmm. If you've never sucked anyone off before, then you're probably not good at it. I wouldn't know the difference between a good one or a bad one, so I guess you will have lucked out at the end- AH!" He never saw Bakugo move, but the demon was suddenly next to him, clawed hand gripping his chin. Izuku is pulled against Bakugo, forced to face him. He trembles at the sight of those solid black eyes staring into his. Izuku can't see his reflection on the black surface. "K-Kacchan? Oh-" Izuku feels Bakugo's hard cock pressing against his thigh.

"Be thankful we have work to do and you're still recovering from our wedding night, or I'd have you fucking screaming yourself hoarse with pleasure at how hard I fuck you,"

Izuku blushes and is turned on by Bakugo's statement.

"Maybe you're not the whiny pushover I thought!" Bakugo eyes return to normal. "Daring to challenge me? Very dangerous, but also very brave! Stupidly brave, but more entertainment than I've had in ages!" He lets Izuku go. "Let's get dressed. We have work to do, then a full, fun night!"

Izuku gives a lopsided smile and thinks, 'what did I just get myself into?'


Iida sits at the library table in the far corner surrounded by towers of books, painstakingly going through each one of them, looking for specific keywords or details. He was getting frustrated at the lack of information. With their newfound knowledge, he hoped to find some amount of supporting evidence, no matter how big or small. But the books turned up with nothing. How can he face Lord Bakugo without any information to help them? Iida removes his glasses to pinch the bridge of his nose. His eyes burn from staring at words for far too long.

'There is no time for rest! Lord Bakugo and the Dom-Omega depend on me! I must focus!'

"Tenya Iida?"

Iida lifts his head to the familiar voice and sight of Shoto Todoroki. He stands up quickly and bows. "LORD TODOROKI!"

"I'm not used to seeing you here," Shoto says, putting his own books down on the table. "Not at Black Ram Hall? Shouldn't you be preparing for the Black Moon Ball?"

"Yes! I'm working on the Black Moon Ball! I'm just doing some side research on-" he has to think of a topic and fast. "On humans! Yes, on humans! For the Dom-Omega! He's pregnant, you know,"

Shoto doesn't look surprised. "I will send him and Lord Bakugo a gift," he takes a quick moment to read the spines of the books Iida is reading. Most have to do with the history of the demon realm. "This wouldn't be about the successor, would it?"

Iida tries not to panic. "Nonsense! The successor hasn't been born yet! I just want to learn more about humans!"

Shoto raises a brow. "So, you're looking through history books of the demon realm to learn about humans?"

Iida snorts and says, "No known books of the human realm exist here! Any information about humans will be found in our history books!"

"I see. Have you had any luck?"

"No, I haven't. All these books...and I can't find what I'm looking for,"

"You know, my family has their own library deep in the bowels of our castle that has been locked away for as long as I can remember," Shoto tells him. "My father always guarded the key to that place. No one was ever allowed in there. If you'd like, I can let you search there and maybe you can find what you're looking for?"

Iida's eyes widen and he puts his glasses back on. "Do you know why it was kept under lock and key?"

Shoto shakes his head. "I don't. When I killed my father, that is one of the first things I did as Blood Lord. I didn't pay it much mind because it was just a dank old room full of moldy books. I know that some are in ancient Abyssal."

"Ancient Abyssal? Damn! I regret that I have never had the time to learn the ancient tongue in full!"

"My sister studies it," Shoto says. "I'm sure she can help you."

Iida claps his hands together and bows deeply to Shoto. "Blood Lord Todoroki, I cannot express my deepest gratitude for your kind offering!"

"I can bring you there now if you'd like?"

"Yes! Yes, I would like that very much!"

"Alright. But before we go, you need to be honest with me first. No truth, no library."

Iida lowers his glasses. "What do you mean?"

Shoto leans in to whisper to Iida. "I know that Izuku is really the successor. What is Bakugo planning?"
