Here is the final chapter! Hope you enjoyed!

The ceremony went well. Izuku teared up at this wonderful day for his brother (before he'd go back to dismantling said brother's empire and capturing or killing him of course).

"If anyone has any reason these two should not be together, speak now or forever hold your peace."

Izuku and every hero present promptly dogpiled Nana, covering her mouth while she desperately tried to object. Across the aisle, several of Inko's coworkers doing the same with Mitsuki while her husband vainly tried to talk her down.

It was nice to see the craziness existed on both sides of this pairing…

Luckily Inko and Hisashi either didn't notice or deliberately ignored them. Soon the two had kissed and were rushing out the door. For some reason Sorahiko had gone missing too…

Hisashi walked out with Inko, to where they should have a car waiting. Due to the importance of this moment, he'd brought his finest classic car. He opened the chapel doors and…that wasn't his car.

He'd brought a classic Gran Torino in pristine condition. The car waiting outside the chapel was a regular consumer grade car that a cheapskate would buy!

Inko looked at him, concerned. "Is something…wrong Hisashi?"

He smiled at her, "Of course not. I was just savoring the moment." They got in the car and drove off together. As they drove Hisashi wondered, what had happened to his car?

Sorahiko hugged his reclaimed Gran Torino. After so many years… finally reunited. The car was back in his hands and pristine as ever.

And all Sorahiko had needed to do was switch the contents of his glove compartment with the Torino's, swap the license plates, then attach the "Just Married" memorabilia to his current car and leave it for the newlyweds.

And Nana mocked him for saving those plates...

The after party was actually going pretty well given that it was full of some of the worst human disasters Izuku had ever met.

Sorahiko was drinking. Banjo was singing bad karaoke, Toshi was telling stories of his exploits as a hero (and gaining several admirers from the civilians and a few mafia princesses), and Tora was currently playing chess with someone Izuku was pretty sure was a Yakuza boss. Nana was with Kotaro's wife and young daughter, floating above said daughter and making funny faces while the young child laughed at her grandmother's antics.

Kotaro Shimura was elsewhere making (very poor) conversation with some of Inko's coworkers around, apparently oblivious to his mother meeting his wife.

Oh and Machia was curled up in the corner, sleeping like a giant cat.

Spotting the newlyweds, Izuku decided to chat with his new sister-in-law.

"Hello!" he said as he walked over. "What are your plans now?"

"Oh we're going to have our honeymoon in Hokkaido," said Inko with a bright smile, "Then Hisashi's finding us a place to move in together!" said Inko.

"That's nice," said Izuku. "Where's he looking?"

"A nice, safe neighborhood with the best of people living in it," said Hisashi.

"What are you going to do? Buy out an entire apartment complex and then fill it with people you'd want as neighbors?" said Izuku.

"That is absurd," said Hisashi, "Where would I get the resources to do that?"

He was totally going to do that, wasn't he?

"What about you?" said Inko. "How's hero work?"

"Oh, pretty good. I obviously can't tell you too much, but me and the others have been making decent headway against several villain gangs. You know, the type led by cult leaders, nutjobs, and losers who cosplay as demon lords."

"Says the man who cosplays as a superhero. In his pajamas," said Hisashi. "By the way, isn't hero work a bit dangerous given your health problems?"

Izuku's eyes narrowed. "Thanks to my power stockpiling quirk, medical treatment, training, and a good diet, my health problems are under much better control then when we last saw each other," he said. "Jerk," he muttered.

"That's what you'd always tell me when you were ignoring them," said Hisashi.

"Well, my teammates are better at catching me lying then you were!"

"Speaking of which," said Inko. "What's it like working in a team of heroes?"

"It's great," said Izuku. "When we aren't working, they're great friends to hang out with! When we are, we have each other's backs whenever things go south. There's no one I'd rather have by my side! Also, Nana was our childhood hero so fighting alongside her is great!"

"She was?" said Inko. "Hisashi never told me that!"

"I'm not surprised. It's actually kind of funny, when we were ten Hisashi had a massive cru-"

"One more word," said Hisashi, "And I'm burning your home down! With your action figures and comics still in it!"

"My comic books!" said Izuku. "You monster!"

"Get used to it!"

"Touch my comic books and I burn…um…your suits!"

Hisashi's eyes narrowed. "Don't even think about it."

"Why are you letting them keep going on like this Inko?"

They glanced at Mitsuki, who'd walked next to Inko. "Whenever I go at it with that bastard, you tell us to stop."

"They're brothers. They're supposed to do that," said Inko, though she did look a bit nervous.

"And I'll have you know that my parents married before having me," said Hisashi with a smug grin.

Mitsuki rolled her eyes. "You say that every-"

"My brother is being a lying liar who lies!" said Izuku. "Mom and dad married a month after he was born."

Hisashi snarled at him. "You little…"

Mitsuki pointed at Hisashi. "You lying son of a bitch!"

"That is also accurate," said Izuku. He smirked. "Mom was known to be an unpleasant person."

Then Mitsuki…laughed? "S-so you're saying...that your brother is both a bastard and a son of a bitch?!" She whipped back her head and broke into full blown cackling. "That's the funniest thing I've heard in a LONG time!"

Hisashi hung his head in embarrassment. "She's going to be bringing this up for a long time, isn't she?"

Inko patted Hisashi on the back while her friend continued her evil laughter. Izuku, seeing his work was done, wandered off so his brother couldn't find him.

He found Second and Miichirou standing in the corner, obviously finding the party too much. He walked up to them and said, "You know, you can leave if you want to. You don't have to be here.

"No."

"We're fine."

"We like being at the party. It's just participating that's too much."

"So your solution is to stand in the corner facing the wall?" said Izuku.

"Yes," they both said.

Couldn't argue with that. Hikage was telling a long, boring story that everyone was trying to find a convenient excuse to get away from. Banjo playing…a pair of banjos (he was pretty good at it too). Tora was still playing chess. He was sitting with his feet on the chair while holding his chess pieces like L from Death Note (and they said Izuku was the nerd…). Tora's opponent took his queen, causing literal steam to come out of Tora's ears.

He finally found Sorahiko watching Nana, who was hugging a crying Kotaro. Izuku hadn't expected them to make up over the course of a single party. Especially not with the way he'd been glaring at her earlier. He glanced over at Sorahiko.

"His wife told me he was a nice drunk. So I started roasting Nana with him until I could swap his sake with my personal vodka," said Sorahiko.

Izuku's eyes went wide. "You gave him that?! How much did you give him?"

"A single glass. Nana's kid's a freaking lightweight."

"Sorahiko, literally the only two who can actually drink that stuff besides you is Nana and Banjo," said Izuku. "Everyone else passes out by the third glass.

"So?"

Izuku sighed. "Never mind."

He left the happy family reunion, only to find himself with a less happy one when Hisashi came up to him, a grave expression on his face. Izuku returned it with a stern one of his own. This was not going to be a pleasant conversation.

"Little brother, we need to talk. Shall we go somewhere more private?"

"Sure," said Izuku narrowing his eyes. Hisashi led him to a backroom and closed the door. Hisashi then said. "So, how shall this affect our little…game?"

"It won't," said Izuku with a stern glare. "Unless you give up your criminal ways, I'm bringing you down. You and your fledgling empire.

"And what of Inko? How will she factor into all of this? You know the problems that come from being close to a criminal, especially a quirked one. So tell me, little brother, what is your plan for my wife?"

"As long as she doesn't do anything villainous I'll keep her out of this. After capturing you I'll hide any connection to you I can find and try to take care of her like a good brother-in-law."

"And before then? You can't seriously expect me to believe that you'll avoid using any public address we have against me?"

"Oh that's easy," said Izuku with a smirk. "Just don't do anything involving your criminal empire from your and Inko's home and that'll be fine. I'm sure you have the resources to commute a few jurisdictions over to work."

"And I suppose you'll be keeping an eye on my home to make sure I keep my end of the bargain?"

"Well that's the price of having a home that I can find you at Hisashi. Besides, I'm giving you a lot more than I have to to keep Inko out of this."

"I suppose so," said Hisashi as he rubbed his chin. "Very well. I accept your terms. Inko is kept out of our war, and I avoid running my criminal empire and engaging in supervillain activities from my civilian ho- "

A cold chill came over them both, followed by a terror worse than anything Hisashi could conjure squeezing Izuku's chest like a vice. He looked up at Hisashi, who was staring terrified at the door. Izuku followed his gaze to find Inko glaring at them.

"You two, explain. Now."

As it turned out, Inko had noticed they'd both disappeared and gone looking for them. And found Hisashi and Izuku just in time to learn Hisashi was a supervillain.

After a quick and thorough explanation by his snitch of a brother, Inko was brought up to speed to the true nature of their…rivalry.

"So, you're a criminal mastermind running a borderline cult of villains using your ability to take and give quirks. You're brother has been fighting you with a quirk you forcibly gave him-"

"It also fused with my own latent quirk!" said Izuku.

"You have a latent quirk?" said Hisashi. "How does it-"

"Later!" said Inko. "Anyway, you both had been doing this for a long time, and all of your teammates knew it," she said looking at Izuku," and none of you told me. Is that right?"

"In my defense I didn't think Hisashi was dumb enough not to tell you!"

"And how would I have explained that to her?!" said Hisashi.

"I don't know! You said she was terrifying so I thought you'd have prepared for-"

"Enough!" said Inko. "Did you ask him if he told me?"

"Uhhh," said Izuku.

"He did not!" said Hisashi.

"You should have," Inko said, her glare intensifying. Izuku wilted beneath her gaze

Hisashi gulped and said. "I know you're upset…"

"Oh I'm furious," said Inko her face becoming one of poisoned honey. "But I'm also kind of flattered."

Flattered?

Hisashi and Izuku exchanged a glance.

"After all," Inko said. "You're giving up that entire criminal empire to spend your life with me. Right?"

Seeing the writing on the wall, Hisashi quickly nodded. "That's right!"

"What?" said Izuku. "That's no-"

Hishashi stomped on Izuku's foot so he'd shut up. "That was neither an assumption, nor a request you idiot," he hissed.

He turned back to his wife. "And have I ever told you you're positively radiant when you're completely terrifying?" he said hoping this would prevent his impending doom.

"Thank you Hisashi," she said. "Now I suggest you both enjoy the party. We'll be discussing this in further detail later." And his attempt had failed. He only delayed the inevitable.

Hisashi and Izuku nodded, then quickly exited the room.

Once Inko had rejoined Mitsuki, Izuku glanced over at Hisashi and said, "You said she was terrifying, but I didn't expect...that."

"Well now you know, and now we're both in for it…"

"Yep…" said Izuku.

Izuku needed to calm his nerves. Nana and Mitsuki were chatting. And mocking Hisashi! That might be just the thing!

He began walking over.

"If you'd bothered raising your daughter, maybe she could have known what a decent guy was like!"

"Hey! I had good reasons for giving her up! What's your excuse? You were her best friend, how could you let a guy like him within a ten-foot radius of her?"

On second thought, maybe not. He slid back next to his brother.

"So, that's the end of it," said Hisashi taking a swig of sake. "Our glorious clash of good and evil ended."

"Yeah," said Izuku. "To be honest I'm kind of disappointed."

Hisashi glanced at him. "You are?"

"Yeah. I always expected it to end in a climactic showdown between good and evil, if not in my lifetime then in future generations. And if you did end it because of your marriage then I was expecting some grand declaration of love and renunciation of your evil ways. Not…"

"Being implicitly threatened by my beautifully terrifying wife."

Izuku shook his head. "Weird tastes…"

"Hey!"

"Well, I guess this is the end of it. On the bright side this could be the dawn of a brand-new era for us both!" said Izuku. He held up a glass. "A toast?"

Hisashi nodded, "A toast."

Izuku smiled and stepped forward. "Here's to a bright fut-" Unfortunately, he tripped and fell, knocking over a large table with a very loud crash.

He quickly got up and surveyed the damage. Everyone was staring. But that wasn't the worst part. Inko was looking at both of them with an annoyed expression. Uh oh.

Izuku and Hisashi, being mature adults, pointed at each other. The crowd didn't seem to instantly turn on the other. Izuku glanced at his brother.

Hisashi was already running away. Backstabbing weasel.

Izuku let the power of One for All flow through him, letting it surge into his legs. With a burst of white lightening, he rushed forward and tripped his brother, running ahead while laughing saying, "Enjoy the honeymoon!"

Because even if he couldn't escape Inko, he could at least make sure Hisashi was caught first!

The End

Author's Note: Unfortunately Banjo, being a dirty coward, used Blackwhip to capture them both, allowing Inko to give them a light scolding about being careful as a prelude to the bigger one she'd be giving all of the heroes and All for One after the party. In exchange for his help, Banjo would receive a slightly lighter scolding.
