Izuku, the magicless sword wielder of the fabled One For All, never lets rules pave his path.
His journey's only goal is to rid the world of All For One's darkness.
Even if it means breaking a kingdom's tradition... or threatening a dragon king with a proposal.

In his defense, Izuku's never been to the Dragon Kingdom. From Prince Todoroki's tellings of the beautiful land, the people who live there are rich in culture and history.
They don't have the best relationship with other lands, but Izuku thinks that's understandable.

From the legends, several other monarchs have tried infiltrating the Dragon Kingdom to steal their natural resources (dragon eggs) for their own use.
Except Dragon Born are fierce warriors who destroy anyone who tries to steal from their fertile lands.
Nobody's ever succeeded.

Since those times, Izuku knows most avoid the kingdom, but that doesn't stop him from laying out his plan to his party two weeks ago.
"We'll go and ask for the king's help in crossing the plagued waters the League hides behind."
"King Bakugo will never help," Knight Iida says.

Prince Todoroki doesn't seem as opposed. "Last time our family visited, he only threatened to feed me to his dragon twice. He's grown friendlier."
Ochaco, their mage, gives Izuku a worried glance. "Izuku, are you sure this is the only way? I could try the gravity spell again-"

Izuku shakes his head, reaching out to grab her hand. "You get sick if you use up too much mana, and we can't risk your health if there's another way. Plus, we'll need you to fight the witch."
So far, Ochaco had been one of the only souls who faced Toga's blood magic and lived.

Her silence lets him glance around the group, offering his hopeful smile. "We'll go to the Dragon Kingdom with our plea. Even if the king will not help, maybe one of his citizens will be kind enough to offer a ride."
Despite their wary looks, all follow him into the new land.

The people are lovely and a little unruly. Iida protests how they fight to solve problems, but gets tricked into training with a few while 'mediating' a conflict.
Ochaco discovers a new line of spells in a hidden village from an old healer that knew Izuku's mentor, All Might.

Todoroki's lineage is a double edged sword in the places they explore. His father is known as both a powerful leader and a scornful tyrant, depending on the lands.
Luckily, it seems the people in the Dragon Kingdom look on Todoroki in benevolence. Especially the main village.

10
Izuku's not sure what he expects when they enter what Todoroki claims is King Bakugo's hometown. But it's certainly not... this.
He's taken aback by how lively the entire village is, full of vitality and cheerful music between the welcoming ambiance.
And the dragons..."Wow."

11
His wide eyes move around to try and capture everything around them. The sky, the roads, even the shops are filled with dragons of all sizes. There's no chains or collars in sight.
The beautiful beasts aren't weapons to the dragon-born. They're members of the village. Equals.

12
"Prince Shoto!" A man with long black hair is the first to greet them, waving both arms over his head. "We didn't know of your visit. Not that we mind!"
"Commander Sero." Despite his higher rank, Todoroki still bows. Izuku smiles at his friend's lack of care regarding hierarchy.

13
"I already said you can call me Hanta." The man laughs, then glances to Izuku and their group in confusion. "These aren't your royal guards."
"Ah, no. I've actually come here at the request of my friend, Midoriya," Todoroki answers. "We'd like a meeting with King Bakugo."
"Ah, no. I've actually come here at the request of my friend, Midoriya," Todoroki answers. "We'd like a meeting with King Bakugo."
14
"Yikes, you sure picked a bad time for that." Hanta waves his hand at the bustling village behind him. "We're getting ready for the Dragon King Festival tonight. He's already been sent off for his preparation."
"Dragon King Festival?" Izuku asks, intrigued by the new event.

15
"Oh, Lady Chiyo mentioned that," Ochaco nods when the group turns toward her. "She said she was invited to the king's festival to witness... something called the Dance of Flames?"
Iida frowns. "That sounds painful."
"Maybe for King Bakugo." Hanta's answer comes with a grin.
Iida frowns. "That sounds painful."
"Maybe for King Bakugo." Hanta's answer comes with a grin.
16
At Hanta's casual response, Izuku frowns. Why would a king put himself in danger? And how could the village be so excited to see the one who offers protection to the town be hurt?
Before he can ask, Hanta snaps his fingers. "Hey, why don't you come tonight as my guests?"

17
"Your family's not here? How is their dragon harness business?" Todoroki's knowledge of the blushing man catches Izuku's interest, and he wonders the history between them.
"It's great, hence why they're out with Cellophane delivering goods. So I have a table for your group."

18
"You won't get in trouble having us come?" Izuku asks, and Hanta waves his concern away.
"King Bakugo might promote me for bringing Prince Shoto to blow off some steam with after the event."
Again, the displeasure of the king resonates in Izuku's chest. "Oh, then... sure."

19
Hanta sends an excited glance toward Todoroki before looking back to the group. "I'll bring you to Mina's tailor shop and tell her you're coming to the festival as my guests. Her and Pinky will be able to make you something cleaner to wear."
"Thank you," Todoroki bows again.
"Thank you," Todoroki bows again.
20
Izuku isn't sure how he feels about the festival, but the preparation leaves him enamored with the Dragon-Born's culture.
He's fascinated by how intelligent and independent dragons are, and the noises they use to communicate with their humans.
Plus, their magic's beautiful.

21
Mina's dragon creates threads of all colors and fabrics, and helps the chatty woman in hand-making the festival outfits for Izuku's group.
Izuku's a little embarrassed being 'prettied up' by the fashionable Dragon-Born.
He keeps his red shoes and One For All as a comfort.

22
By the time they're done, night has fallen. Hanta and Mina lead the group up the winding path toward the festival, Pinky letting the women hitch a ride to keep their heels clean.
Izuku enters the decorated green and is blown away. The lavish festival is already in full swing.

23
Music, food, and ales of all kinds fills the spacious arena, and he's sure the whole village is in attendance. It's a very active party.
What catches his curiosity is the circle of fire in the middle of the green. He itches to know how it burns so evenly, and its meaning.

24
There are several people around it, dragons as well. He sees some trying to get close to the flames, but the heat seems to keep them back.
A few direct their dragons to flap their wings at the fire, but even that barely moves the circle. The goal is maybe smothering the flames-

25
"Ah, there he is." Todoroki pulls Izuku's attention.
"Huh?" He follows the prince's pointed finger and connects the dots.
There, sitting higher than the rest of the party, is a man who looks bored. His cheek's pressed to his first, leaning on the throne. And he's... stunning.

26
"That's King Bakugo?" Iida shifts his glasses. "He looks our age. I was expecting someone older."
Todoroki nods. "His parents left him the kingdom when he turned 21 last year."
"Did his parents..."
Before Ochaco can finish, Mina laughs. "No! Queen Bakugo decided to retire."
Todoroki nods. "His parents left him the kingdom when he turned 21 last year."
"Did his parents..."
Before Ochaco can finish, Mina laughs. "No! Queen Bakugo decided to retire."
27
"She can do that?" Izuku's floored with the answer, unsure if he could ever imagine Todoroki's father giving up his role willingly.
But Hanta only shrugs. "She's been ruling since she was sixteen. The Queen got bored, and wanted to enjoy her time with her husband. So she quit."

28
"King Bakugo kicked her from the kingdom for a decade, but I think he's just mad about the festival she invoked before she left."
At Mina's giggle, Izuku has to ask. "Why does the king look upset? Isn't this whole celebration for him?"
Hanta gives Mina a smirk. "Yes and no."

29
"King Bakugo is supposed to use the event to find someone to help him rule the kingdom, but Kat-" Mina catches herself. "I mean...King Bakugo would rather eat spoiled fish and have an 'extra' bugging him."
Hanta laughs at their surprise. "That's our king, blunt and stubborn."
Hanta laughs at their surprise. "That's our king, blunt and stubborn."
30
"Its customary for members of the royal family to participate in proposal dances at events." Todoroki explains. "All those who wish to be considered step in the circle, and the one the king approaches is who he accepts as his future partner."
Izuku frowns. "But the fire...?"
Izuku frowns. "But the fire...?"
31
"It's from Dynamight." Mina sighs like the name means something. "King Bakugo's dragon. His magic is so explosive, his fire breath can't be put out with wind or water."
"Even I have to put in extra mana into my ice to smother it."
And it's Todoroki's comment that stuns Izuku.

32
"He made a barrier so nobody can ask to be considered." Izuku's eyes widen at the loophole, then looks up at the king with admiration.
King Bakugo isn't just a handsome face with a lucky bloodline; he's powerful, intelligent...
He's perfect for the fight against All For One.

33
"So King Bakugo has to consider anyone who gets in the circle?"
"Oh no." Ochaco grabs his arm. "Izuku, you're not serious, right? The flames are strong enough to burn Todoroki's ice, and you don't have protective magic!"
"Or any magic," the prince says without hesitation.

34
Izuku only smiles. "We need his power."
"We also need you!" She shouts, but he stays gentle when he removes her hand.
"I'll be okay. A hero always finds a way." Then he walks forward, tugging One For All from its sheath on his back as he approaches the blistering flames.

35
The fire's a death trap. He knows that even with his trick, if he lingers for a second too long, he could pass out and die.
He'll need to switch between mana forms quickly. Closing his eyes, Izuku ignores the murmurs around him and activates his sword. "Float."
Then he jumps.

36
He's used to people's gasping when he reveals One For All, so he focuses on using the levitation to angle high enough to not feel the heat.
It's hard to balance two different manas at once, but with death staring him in the face, he manages it. "Blackwhip, defense mode."

37
Black tendrils spill from sword, and he knows he looks eerie with the energy cloaking him. But they'll limit the burns for his next insane move.
"Alright. Here we go." Izuku glances to the king, whose narrowed red eyes look kinda pretty in the inferno's glow. "Float, release."
"Alright. Here we go." Izuku glances to the king, whose narrowed red eyes look kinda pretty in the inferno's glow. "Float, release."
38
The instant drop down plunges him straight into the fiery entrance. He hisses at how quickly the burn rips at his skin, even with Blackwhip around him.
Heat siphons the air from his lungs, and his pained tears turn to salt in his eyes. Everything hurts, and he feels suffocated.

39
But the second he feels the ground under his feet, he croaks out his trump card. "F-Fa Jin."
Muscles scream when he bounces a few times before the build-up is enough. Right when he starts seeing black spots in his vision, his body launches up an out of the flaming prison.

40
Unlike float, he only lifts high enough to bounce over the flames, shins nicked by how close he gets before plunging to the ground outside of the fire.
His dismount isn't exactly 'heroic', but that doesn't matter.
"Izuku!" He hears his friends rush over to help him sit up.

41
Todoroki's chilled hand is already misting a snow-like spell around his arm, which looks pretty badly burned despite Blackwhip's defense.
"I'm okay," he says despite his wince. "I was only in there for a few seconds."
"What was the point of that?" Iida asks, distraught.
"I'm okay," he says despite his wince. "I was only in there for a few seconds."
"What was the point of that?" Iida asks, distraught.
42
He doesn't answer him, forcing his eyes up to see if the king is still watching.
Izuku almost flinches when the man of the hour is suddenly in front of him, arms crossed over an unfairly bare chest. "Oi, what the fuck was that mana? And who the hell are you?"
"I'm...Izuku-"

43
"More like Deku, an useless idiot trying to kill himself at a King's feast." Despite his words, the king crouches down to lean his face closer to Izuku's.
Even with his arm's pain, Izuku's cheeks warm. "Uh, you're kinda close-"
"Isn't that what your little stunt was for?"

44
"Huh?" Izuku loses the plot for a second when the red eyes stare into his, but a strained cough behind him makes his head stop floating. "Oh, um... no, actually. I don't wanna marry you."
"Hah?" Somehow, the answer only seems to annoy the king more. "First off, why not?"
"Hah?" Somehow, the answer only seems to annoy the king more. "First off, why not?"
45
"It's not that I couldn't!" Izuku doesn't know how the tables have turned so much. "You're probably nice."
"Nice?! What's IcyHot lying for-"
"I just don't know anything about you. What you like, or hate, or-" He laughs awkwardly. "Shouldn't I... at least learn your full name?"
"Nice?! What's IcyHot lying for-"
"I just don't know anything about you. What you like, or hate, or-" He laughs awkwardly. "Shouldn't I... at least learn your full name?"
46
The king looks almost like a dragon in a human disguise when his nostrils flare. Their noses brush when he growls his answer. "Katsuki Bakugo. King of the Dragon Born."
"Nice to meet you, Ka-ah..." The intimacy of their current position trips Izuku up, fumbling out. "Kacchan."
"Nice to meet you, Ka-ah..." The intimacy of their current position trips Izuku up, fumbling out. "Kacchan."
47
For a long moment, the festival goes silent.
"Alright, Deku." Izuku isn't sure if the shiver down his back is from fear or the warm breath that passes alone his lips from Kacchan's sardonic tease. "If you ain't here for marriage, then why'd you jump in Dynamight's flames?"

48
"We need your help. All For One's darkness is back."
The mention of the evil sorcerer makes the people of Kacchan's village gasp and murmur in fear.
Kacchan even tenses. "Go on."
"He's spread a plague in the water surrounding his League's base. It kills all who touch it."

49
Izuku offers his plan. "Unless we have something powerful enough to withstand the mist and carry our group, they'll have the upper hand. And if the darkness spreads, it could kill us all."
"Large and powerful." Kacchan catches on. "You mean Dynamight."
"Not just Dynamight."
"Large and powerful." Kacchan catches on. "You mean Dynamight."
"Not just Dynamight."
50
Taking a risk, Izuku grabs Kacchan's arm, ignores the crowd's reaction to bump their foreheads and speak softly.
"From the stories All Might told me, Dragon Born are the most powerful. Your battle skill and intelligence could change the tides for us."
"From the stories All Might told me, Dragon Born are the most powerful. Your battle skill and intelligence could change the tides for us."
51
"Why should I help a nerd like you?" Despite his insult, Kacchan doesn't move away or shake off Izuku's scarred hand.
"Because," Izuku answers. "I stepped in the circle, and you came to me."
"So?"
"Oh." Todoroki blinks. "You completed the tradition. You're courting Midoriya."
"Because," Izuku answers. "I stepped in the circle, and you came to me."
"So?"
"Oh." Todoroki blinks. "You completed the tradition. You're courting Midoriya."
52
"Hah?!" Kacchan finally flinches back to stand, glaring daggers into Todoroki's calm composure. "What the hell are you saying?"
"He's right." Mina looks too excited. "Izuku stepped into the circle, and you approached him! That means that you've offered your hand as his mate!"
"He's right." Mina looks too excited. "Izuku stepped into the circle, and you approached him! That means that you've offered your hand as his mate!"
53
Kacchan's hands actually spark from his anger, and Izuku rushes to stand with his offer. "I'll trade you!"
"Trade? You tricked me!" Kacchan fangs look ready to bite him in half.
"After you help me beat All For One, I'll reject your proposal."
"Or I just blow your head off!"
"Trade? You tricked me!" Kacchan fangs look ready to bite him in half.
"After you help me beat All For One, I'll reject your proposal."
"Or I just blow your head off!"
54
"If I may interrupt," Iida bows to Kacchan. "If you're betrothed, doesn't that imply all other considerations would be paused?"
Finally Kacchan lowers his hands. "I guess."
Ochaco chimes in. "Plus, if you're with us, nobody can plan more marriage festivals, right?"
"Tch."
Finally Kacchan lowers his hands. "I guess."
Ochaco chimes in. "Plus, if you're with us, nobody can plan more marriage festivals, right?"

55
"And if you do fall for Midoriya, then you can consummate after our journey."
Todoroki's blunt 'help' makes Izuku sputter, but Kacchan arches a brow at him. "Like that'll happen."
"He may surprise you, King Bakugo." Somehow, Todoroki sounds a little too sure of his claim.

56
From the tense shoulders and wider eyes, Kacchan seems unnerved by it, as well. "Fuck you Icyhot! And you, Deku."
"Uh, y-yes?" He straightens up when Kacchan steps forward and yanks a fang earrings from his lobe.
"Here." Then it's presented to Izuku, who blinks at the offer.

57
"Oh, thank you but I don't have... my ears pierced?"
"Raccoon Eyes can make it a necklace, I don't care." Kacchan glares at him. "It'll show people you're mine."
He doesn't know why the comment flushes him, since none of this is real. They're only technically engaged, yet...

58
"Okay, then... I accept your courting."
When he picks the earring up from the smooth palm, the village cheers. Even his friends join in when Hanta and Mina grab them in hugs and jumps around.
Izuku looks at Kacchan, who only watches him for a second before storming away.

59
"You actually did it!" Ochaco jumps forward to hug him, nearly knocking him into Iida and Mina.
Todoroki pats his head like a proud father. "Good job. Bakugo will be a great asset for us."
"If we can manage his-" Iida pauses at the explosion in the distance. "Terrible temper."

60
Izuku looks at the path Kacchan took as the party continues around him. Because he hadn't meant to tie the king to him, not like this.
'Well,' he thinks, looking at the jewelry in his hand. 'You'll have the whole quest to make it up to him.'
And maybe now, Izuku has two goals.
