Katsuki's magic kicks into motion the second he hears the first window smash.
He doesn't question what's going on, or why there's a horde of living tree branches and mud pies trying to bite his ankles.
Katsuki knows they're just a distraction.

Despite this, he can't ignore them. The banquet air is plagued with scents filled with the panic of the citizens. It almost knocks Katsuki off his feet from how potent it is.
The one downside of having an alpha's sharp senses is the backlash when omegas around him are upset.

Breathing through his mouth, he goes against the crowd, who are rushing to the door in their frantic need to get away from danger.
Katsuki's palms crackle with his magic, grinning as he easily mows through the weak enemies.
His eyes scan the ballroom, needing to find his-

There, helping an omega by fighting a stupid goblin bare-handed, is Izuku. Like an idiot, he's not thinking about himself, kicking away the ankle-biter.
And he knows Freckles isn't a pushover, even in his royal garb. He looks like an emerald fire dancing through the enemies.

But when he's distracted, probably looking for something to arm himself with, three more of the annoying creatures try to ambush him.
Katsuki's already sprinting toward him, hands taking no prisoners while he scorches everything in his path.
Icyhot's magic makes it there first.

Normally, seeing another alpha protect the nerd might make his own snarl, but the moment's too chaotic to care about dumb pride.
For now, Izuku's safe, and Katsuki focuses on blowing up the enemies.
Support comes in soon after, and Glasses takes over the goblin containment.

Katsuki wipes sweat off his forehead before he looks up, and it only takes him a moment to realize what's missing.
There's no trace of Izuku. Except that's not true, because Katsuki's nose instantly picks out his alluring scent without effort.
It trails out the courtyard door.

"Fuck." He sprints after the scent. Nothing would send Izuku running AWAY from his people in need. Not unless...
Katsuki's biggest fear isn't what was in the banquet hall, but what he hadn't seen during the attack.
Because he knows Beakface's magic. But he hasn't shown himself.

'Was this his and Creepy Hand's plan?' he thinks, heart racing as he rushes through the empty space and glances around. The trail isn't strong, meaning he's not sure how long it's been since Izuku ran through here.
But if he's the omega, and wants to confuse a Sange prince-

10
Katsuki's eyes snap to the maze at the same time a loud shout echoes from deep inside.
His alpha snarls at the noise. He doesn't think twice about his next step.
Hand bursting with magic, he shoots it into the shrub walls of the maze, jumping through each new shortcut he makes.

11
He doesn't have time to try and remember the path he's only taken a few times, and silently vows to apologize to the groundskeepers AFTER he rescues their queen.
As he's carving his new path, he can hear a fight growing louder. Apple blossom is drenched in a dark, soil scent.

12
And he knows that ironic smell from the alpha obsessed with being 'cleansed' far too well.
'That fucker', Katsuki thinks, seeing red while burning through another wall.
His alpha claws at his skin, desperate to get out of the restraints he always keeps on the beast inside him.

13
When Katsuki blows through the last barrier, it reveals the brutal fight between the two missing people.
But Izuku's on the OFFENSE, surprising him.
He can see the bluntness and wrong size of the weapon for the smaller omega. Freckles is using it more like a mace than a sword.

14
Beakface has NEVER been one to use weapons, his magical range being the highest of the princes. But he's only using one hand to whip up barriers and blockages from the surrounding nature, his other holding a... dagger?
One that's glowing pink, which isn't the coward's magic.

15
Still, it seems Izuku's focused on disarming him, avoiding the surges of sentinel magic like the spirit of battle fuels his movements.
The fierceness in the green eyes staring Beakface down holds a coldness he's never seen in the queen's expression.
Like he won't accept defeat.

16
Beakface raises the maze's stone floor as a wall to stop Izuku. His bunny uses it to spring off, spearing into the prince and sending them both rolling across the hard ground.
Izuku ends up on top, using his foot to kick Beakface's wrist into the ground.
The dagger slides away.

17
Heaving over the man pinned down, Izuku lets go of his useless weapon to keep Beakface contained. Powerful thighs now lock around the alpha's legs and immobilize him with a forearm to his neck.
"Yield," Izuku demands, and Katsuki feels a surge of pride at the powerful display.

18
The nerd doesn't need Katsuki to sweep in and save him. His understanding of his body, and how he uses it to overwhelm those who underestimate his skill, is something only Freckles can do.
Izuku's beautiful, walking down those stairs, but here?
He looks like Katsuki's perfect-

19
A flicker of pink catches the corner of Katsuki's eye too late. "Izuku, look out!"
Before the omega can react, the dagger stabs into the freckled bicep, the sentinel branch wielding it falling limp after.
Freckles hisses at the pain, pushing off the prince and stumbling back.

20
The sight of blood pouring out of the wound snaps something in Katsuki.
Before Beakface can take advantage of the moment, Katsuki blasts him back to the ground.
His magic doesn't lessen as he approaches the pinned man, mind growing hazy with the scent of sweet blood in the air.

21
'I'll kill him,' he thinks. He cuts off his magic when he drops to his knees, grabbing the writhing man's throat. Claws dig into the other's neck.
They only expose themselves when his alpha's taking over. It's a warning he's losing control.
For once, Katsuki doesn't care.

22
He doesn't enjoy death. Even when he's on the battlefield, Katsuki isn't one who feeds his alpha's pride by taking the life of others.
It's always been a duty, one he only engages in to protect those who can't do it themselves.
But something dark blooms in his chest now.

23
'He hurt omega', his alpha snarls, his hands squeezing tighter on the neck that he knows he could snap with a little more pressure. 'He made MY omega bleed!'
The line between himself and his alpha is getting thin. He feels unhinged, almost like a pre-rut, needing to dominate-

24
"Prince Katsuki, that's enough." A familiar magic wraps around his wrists, pulling them back far enough to stop suffocating the now coughing prince.
Venom drips from his mouth as he snarls, glaring over his shoulder at his mentor. "Release me, NOW."
"I can't let you go feral."

25
Comb-Over's words freeze him. His heart's still pounding, needing to make Beakface pay for his crimes.
But going feral, near an unbonded omega (who his mentor stands in front of protectively), is very dangerous. Katsuki wants to say he'll be fine, won't ACT on his instincts...

26
If it was any other omega, Katsuki could make that guarantee easily.
But it's Izuku, the only one that'd push him to murder someone with his bare hands.
Noodle Neck's magic fibers stay strong on his wrist as he speaks. "Queen Midoriya needs you to calm down so we can help him."

27
"Help?" Some of the haze in his head clears at the concerning thought. "He's hurt?"
"I can't check his wound or his current state if I'm worried about your condition." For a beta, Comb-Over holds an aura that demands quiet respect. "I trust my prince can control his bloodlust."

28
Katsuki growls, alpha snarling at the unspoken request. His mentor wants Katsuki to give up his desire to get revenge on Beakface, and let 'justice' choose his punishment.
For Izuku, that probably won't be the death he deserves.
But the moment is taken from his shaking hands.

29
The ground shifts under him, and he's knocked away from the prince. In a second, Beakface is gone, using his magic to vanish from sight.
"Get back here, bastard!" Too busy fighting his alpha, Katsuki doesn't notice the prince getting his second wind to escape the situation.

30
He wants to go after him, to wring the coward's little neck, but a whimper in the air snaps his attention behind him.
Izuku's kneeling on the ground, curled in on himself as he flinches and trembles from pain.
All of Katsuki's murderous rage drains away in seconds. "Freckles?"

31
Slowly, the nerd lifts his head, breathing through clenched teeth to stave off his agony. And sure, the dagger got him good, but he knows Izuku's pain tolerance is insane.
He literally forces himself to experience a full heat in one night. A stab wound's nothing for his bunny.

32
Except something's wrong, because Izuku's not offering a smile or downplaying the blood rolling down his arm.
For just a moment, the nerd looks so... helpless.
"The dagger." Still, Freckles isn't going to let whatever is happening stop his brain. "It's a-aphrodisiac magic."

33
Finally, Giraffe Neck releases Katsuki from his magic, moving to help Izuku ease into a more comfortable sitting position. "Meaning it's shutting down your omega's normal inhibitions-"
"No." He expects to hear heat in Izuku's voice, but it only carries pain. "I'll b-be okay."
"No." He expects to hear heat in Izuku's voice, but it only carries pain. "I'll b-be okay."
34
"Your Highness," Comb-Over speaks with respect while pressing the back of his hand on the omega's forehead. "I fear the fever will get worse if you ignore it. Forgive my question, but do have a royal consort?"
"No." Izuku shakes his head. "I just need to g-get to my chambers."
"No." Izuku shakes his head. "I just need to g-get to my chambers."
35
Katsuki scowls at the conversation, hating every aspect of it.
He hates seeing Izuku in severe pain, though isn't sure if he's telling the truth about being able to manage it without intervention.
He's got that damn spell on him, right? That's supposed to suppress his omega.

36
But thinking about pushing the envelope and siding with his mentor is also leaving a bitterness in his already compromised mind.
Why would his bunny NEED some random asshole to 'help' him? Freckles doesn't trust anyone, and if that's forced on him by King Yagi or the advisors-

37
"I'll bring him to his room." Katsuki ignores his alpha's restlessness as he moves across the destroyed space, crouching down on the other side of Izuku's trembling body. "Old man, I need you to keep this shit between us."
"I would advise against not alerting a medical aid."
"I would advise against not alerting a medical aid."
38
He scoffs at the logical (but useless) reply. Katsuki shoos his mentor's hand away before cupping the flushed cheek closest to him. "Nerd, who knows of the spell?"
Izuku's lashes flutter at the touch, but he's not sure if it's from pain or comfort. "Mm... only L-Lord Shoto."

39
"Of fucking course." Katsuki tries not to let his irritation bleed into his tone when looking to Comb-Over. "I'll watch over him tonight. If I don't send word he's beaten the spell by morning, tell Icyhot to find the mage and bring her to the castle. He should know what to do."
40
His mentor watches him with his normal cool composure. "And you think you'll be able to manage whatever he needs?"
"What the hell." Katsuki's ears feel hotter at the question. "The nerd said he's got this under control, and I believe he knows his body better than any of us."

41
"Kacchan." The voice still shakes with whatever sensation Izuku's caught in from the dagger, but there's a soft awe.
If he looks down, he knows those pretty green eyes will be wide and doe-like, which he CAN'T see right now.
Instead, he collects Freckles into his arms, rising.

42
"Very well." Long Neck stands, bowing to them. "I trust you two have built enough of a relationship to work through this together. If you need anything, call for me, and I'll do what I can to support you."
"You should focus on figuring out how those assholes got in the castle."

43
"Not Tenko." Izuku's struggling to breath, legs twitching horribly in Katsuki's cradle. "He's... helping me."
"What, like a spy?" When Freckles only hisses and buries his face into Katsuki's neck, nuzzling his gland, he knows he won't get much from him until the magic's gone.

44
He ignores the rumbling in his chest from the intimate movement when he looks to Comb-Over. "I need answers for Beakface and King Asshole's movements."
"I'll meet with Trev's generals and gather all I can."
"Good." Katsuki only gets two steps away before pausing. "And thanks."

45
Both know what he means.
Not allowing Katsuki to kill the coward in his feral mindset is the right call. From how Izuku whimpers under his breath in need, the sweet hint of his slick, and how he scents Katsuki's neck...
Katsuki needs his head on straight to survive tonight.

46
The mature mentor only chuckles. "No matter your title, loyalty, or age, you'll always be someone I will protect. Even from your own instincts with your potential... alliance."
Katsuki’s smart enough to know the man wants to say something else.
Partly because, deep down, he...

47
"Stop with the weird innuendos." He holds Izuku closer, burying his face into sweaty curls as he walks again. "Remember my orders."
"Of course, young prince."
The nerd suffers quietly on their walk, Katsuki getting him through the castle before he lifts his head. "I'm sorry."

48
"For what? Beakface being the worst?" Katsuki scoffs, taking his time moving up the stairs toward one area of the castle he's never dared to go; the queen's chambers.
Then again, if what his bunny said before was true, no alpha has.
"For pushing you away. For... hurting you."

49
The comment stops Katsuki in the long hallway that leads to the forbidden suite. His eyes stay forward even as his arms tighten around the overheated body in his care.
"You had your reasons." Stupid ones, Katsuki thinks.
Izuku whines, forehead pressed to his now-clenched jaw.

50
"I just wanna see Kacchan happy," is the slurred out answer.
It isn't heat-filled, just impulsive. Like the mage's spell and the aphrodisiac magic are clashing, making him say random thoughts.
Katsuki... hates this. It's not Izuku, not the man he burns for every lonely night.

51
Sighing, Katsuki turns his head, brushing lips over fevered skin. "Then let me take care of you. Stop pushing shit away. Lean on me, dumbass."
"...There's... tonic. In my room," Freckles mumbles, body clenching as he groans in discomfort. "You can go in."
Izuku's trusting him.

52
"Tonic. Got it." Katsuki takes a final breath to steel himself before he walks forwards, pushing into the queen's nest.
Somehow, the apple blossom isn't as powerful as he expects. As if it doesn't come out when Izuku's alone.
'Just with me' his alpha croons, far too happy.

53
Stuffing down the thought, he moves quickly through the space, finding the bedroom easily.
He expects some lavish nest, but the nerd's is... barely made. As if he's just a pup STARTING to have the nesting urge.
Izuku still recognizes it, purring as he begins to wiggle in need.

54
"Yeah, hold on." He does his best not to touch, unsure if his scent would be welcomed inside the intimate space.
The nerd sighs once laid down, eyes half-lidded but seeming more aware than before. "My nightstand."
Katsuki glances to the mentioned space, sees the unique bottle.

55
He hates the juniper scent, but pours the liquid into Izuku's pretty mouth.
Once it's done, Katsuki turns to the queen's curled body. "What now?"
Izuku's eyes squeeze shut, still in pain. "Prepare an ice bath."
And Katsuki's stomach drops at the implication.
Izuku's in heat.
