(Years later…)
"Dad, Dad! Look!" a white-haired girl with several strands of blond said as she crafted a small ice castle out of nothing.
The King of Arendelle picked her up and spun her in the air at arm length joyfully.
"That's wonderful Kusa," Naruto complemented as the Queen coughed a bit behind the pair to get their attention.
They were busy playing with each other and didn't realize she had entered the room moment ago after dealing with some important task.
"Momma here; let's run," Naruto called out childishly with a foxy smile, but his leg was frozen in place before he could.
A flaming wisp was floating nearby.
It smirked at the idiot.
The crowned princess disappeared in a swirl of flames and materialized by her mother's side.
The queen immediately kneeled and patted the girl lightly on the head.
"Now, Kusa, you shouldn't teleport like that. It's very dangerous," Elsa scolded her daughter, who nodded in shame.
Flame teleportation had an inherent danger of reforming in an already occupied space as demonstrated by the King a while ago.
"Can we go visit the town? And can we see Aunt Anna and Uncle Kristoff? Oh yeah, Olaf too, he's funny! Can we? Can we?"
The three year old asked her mother, who rubbed her nose a bit and picked her up.
"Of course, we can," Elsa hugged the girl and headed toward the door.
"Umm… Elsa? What about me?" Naruto asked.
He was still half frozen.
The Queen looked back at her husband.
"You can free yourself, I'm still angry at you for burning off the prince's clothes in public," Elsa said with a slight approval voice and disappeared.
The Southern Isles had decided to punish Hans's transgression and placed him in Arendelle's custody for the duration of five years.
Naruto can control his flames to burn specific things now and always used Hans as a testing dummy.
He was still annoyed at how the disgraced prince had tricked him and tried to murder his wife.
"I'll go tell the guard for a new set of clothes," Kurama said before floated out the room and into the hall.
Since Naruto tend to set fire to his own attire when thawing out of his wife's ice prison, they have stocked countless of suits just for the occasion.
The couple teased each other a lot.
Just recently, Naruto spent a whole day encased in ice block because he took Kusa for a flight after the Queen told him not to.
(Arendelle)
Not much has changed in Arendelle in the four-year time, except the town got wealthier thanks to their ruling monarch.
Naruto's power could smelt any ore to its highest purity state, and he was capable of crafting some of the most complex ornaments.
Tourists were always a big bloom in town aided by the fact that people far and wide wanted to see the royal and magical family.
While they were here, they might as well enjoy the never-ending wonderful climate.
The city was always in summer while the mountains side was stuck in winter.
Naruto and Elsa walked side by side down the cobber stone street as Kusa skipping just ahead of them.
"Yo-ho, come to see my ware?" Oaken called out from his counter.
He was sitting in front of his shop as Naruto waved at him.
"My supply is up, but my demand is even higher. It was just like before, how I fix this?" Oaken asked as Naruto chuckled.
Influx of tourists really made business in Arendelle bloom, so much that supply had become a constant problem.
Elsa was waving at several other bystanders, who greeted her and the crowned princess; the king and queen tend to wear simple clothing, unlike those of nearby kingdom.
"Run, meanie Kusa is here!" one of the boys called out as several more pointed at the girl.
The crowned princess huffed a little and creating a swirling ball of fire and ice in her each of hands, but Elsa tapped her on the head in a patronizing manner.
The fire and ice dissipated as Kusa's cheek puffed up.
"But they tease me!" the little girl said and looked at her mother.
"Now, Kusa, you might hate them now, but you will learn to love them. They are your future citizens, hatred and self-loathing will make you lose control of your powers. I know because it happened before," Elsa said while rubbing her daughter's cheek gently.
"Beside, people do change. Did you know that when your father and I first met, he actually attacked me," Elsa said as Naruto stood behind her, listening in.
"Then you turned me into an ice sculpture and crashed a castle on top of me," Naruto argued back. Elsa turned around and stood up before jabbing her finger on Naruto's chest.
"Are you regretting staying with me?" Elsa asked; her ruby eyes glared directly at Naruto's.
"The only thing I regretted is that you didn't give me another child sooner!" Naruto replied before rubbing Elsa's swollen stomach. The wise men said the chance of it being a boy was very high.
"Just few more months and daddy will show you…" Naruto did baby talks as Kusa giggled at her father's behavior. Naruto realized everyone was standing around him with a grinning face and muttering something with each other.
"Ahem! Move along or I will arrest you for making fun of your King!" Naruto said after standing up. He placed Kusa on his shoulder afterward while the citizens dispersed.
"Your mother and I fought when we first met and now we married and have you," Naruto said as he skipping down the road as Kusa laughed.
"Does that mean if I attacked the boy before, I will marry him?" Kusa asked as Naruto stopped dead in his track.
"I sure hope not, you can do better! Let's go see your uncle and aunt via Naruto's express. Just like your mother used to!"
Naruto said before jumping off in the air and used his fire magic to propel him while his daughter, Kusa, screamed excitedly, holding onto the King's head.
The crown princess still couldn't fly perfectly yet, as her magic hasn't developed fully.
She could barely make a miniature ice castle, not as complex as her mother.
Both daughter and father left the Queen and dozens of bodyguards behind.
Elsa just shook her head and continued walking toward where her sister now lived while rubbing her stomach.
"I hope you will grow up to be like your father, he had shown me that my life was worth living."
