Katsuki walked down the halls, looking for his daughter. He couldn't find her. It was pissing him off, "Katsumi? Katsumi? Where are you? You brat you better come out." He sighs before seeing Uraraka, who was walking down the hall while carrying blankets. "Hey round face, have you seen Katsumi?"

Uraraka sighed, she has tried to make the king stop calling her that, but it seems he is never gonna stop. "Not since this morning, your Majesty." He nodded and walked to the kitchen, "Hey sparkle, Katsumi's not in here, is she?" He asks, looking at the chef Aoyama. "No, Your Highness, but her birthday cake is. Ten petite candles."

King Katsuki sighed, walking out of the kitchen. He needed to find his daughter. He just didn't understand where she could have went. He eventually walked to the ball room. He saw his wife, who had happened to be helping plan the party. He smiled, he loved watching his wife work. How she took charge and didn't take shit from anyone. He loved it, "Hey shitty girl, have you, by any chance of the heavens, seen Katsumi?" He asked, causing the queen to look towards him, "No, haven't seen our melody. You know her. She is probably outside somewhere looking for a way out. She will eventually come back, don't you worry."

Katsuki nodded while the queen made her way over to him, "You don't need to worry about her firecracker. She is our daughter. She is strong, smart, explosive, and ect." The king nodded before giving his wife a quick kiss, "Alright, well I am gonna get ready and you should do the same." He says, (Y/N) nodding in response, "I will come with you. Let's go." She says, taking her husbands hand and headed off to their room to change and get ready.

The queen was right about her begin outside...but where outside is surprising. She is in the ocean. Swimming around while Aizawa watched from the rock he had climbed on. Denki flew above before landing on the rock, right beside of the crab. "Whoo-eee! This is gonna be some kind of shindig. Yes, sir, a real swanky soiree, as they say. There's just one thing missin': The guest of honour!" Denki says happily, while Aizawa sighed, muttering to himself how he hated that he was watching another teenager, "Aizawa, you watch over her," he said. I'm too old for this. A crab my age should be retired,getting a tan...playing sea golf...sipping a tuna colada! Not baby-sitting another teenager or well...a brat, as she isn't a teenager yet."

Suddenly the girl had come above the water her long hair blonde hair in a ponytail while wearing her camisole and pantalettes. It was white and also a bit puffy, "Katsumi!" Aizawa yelled when he saw the girl. Katsumi smiled and swam over to her her friends, "Hey, Denki! Hey, Crabzawa! What's kickin'"

Denki, begin a stupid bird, said, "Uh,what's kickin'? Hmm... let me see." He He knocks himself on the head before saying, "Don't rush me!"

"Ha! You know perfectly well what's kicking! Now, come along. Your gonna be late for the..." Aizawa couldn't even finish what he was gonna say as Katsumi apologized, "Sorry, Aizawa."

"Katsumi, child, how many times do I have to tell you?" As he spoke Katsumi copies him, "It is expressly forbidden for you to be swimming beyond the safety of the sea wall." Aizawa stops speaking as Katsumi continues, still imitating him, "Any such swimmin' is a reckless disregard of the rules. Don't ya know?" It is quiet for a moment before Aizawa glares at the girl, "Stop doing that."

Katsumi giggles as she swims a bit out in the water, "Oh, Aizawa I can't help it. I just love the sea!" She says, swimming out more, "Hey! Come back here! You're just like...like your father." He whispers the last part, seeing more of her father in her like everyday. She dived and a fish waved to her and said, "Hi, Katsumi." The girl smiled and sometimes reflected light in the water catching her attention. She swam deeper and found the locket. Picking it up and inspecting it before going back up to the surface.

Now in a cave in the icy waters overhaul is messing around with a spell for Chronostasis while Shin & Joi, who happens to go by mimic watch. These two were also giant manta-rays.

"Ok, ok, ok, Trust me. This time I'm sure I've got it right." He says while the shark sighs, "Yeah, that's what you said last time, and I was sore for a week."

Overhaul sighed, "Oh stop your carping and stand still." The shark shivered as he prepared himself for pain, "Oh, this is gonna hurt."

Overhaul casts the spell & a green lightning bolt hits Chronostasis. He starts getting bigger, making overhaul smirk, "Yes. Yes. YES!" Chronostasis was also happily before he noticed he started to shrink again, ""Uh-Oh!" The spell backfires and he shrinks, making Overhaul sigh in frustration, "Huh." He then throws another bottle into the cauldron and  Chronostasisis turned into an unidentifiable gray fish.

Overhaul becomes even more frustrated & throws in more bottles, turning Chronostasis into something weird each time until he's back to being small. The two manta-rays chuckle at the sight. "Oh. It's just no use. The power of the trident is just too strong for me to overcome."

Now Chronostasis, having a death wish muttered under his breath, "I bet Shigaraki could've done it." Overhaul glared at the fish, "What, was that ,you said?" The tiny shark shook his head, "Nothing, I'm just saying-" Before he could finish Overhaul throws a vial at him, but misses.

"Stop, criticizing me! That's all that bastard All for one ever did was criticize me. It was always,"Shigaraki this" or,"Shigaraki that"or,"Kai,why can't you be more like Shigarki?!" Overhaul hurls a starfish like a dart at a picture of Shigaraki.

"Well, it's not his fault I got miniturized. It's yours!"

"Is not." He says.

"Your fault we had to hide out here for TEN FROST-BITTEN YEARS!"

"Is not!"

"YOUR FAULT WE CAN NEVER SHOW OUR FACES IN POLITE SOCIETY AGAIN!"

"You're really pushing it, Small-Fry."  Before the two could finish their fighting a shell that seemed to be some king of projection device had green smoke come from it, it showed Katsumi, holding the locket. The two swam over and smirked before looking at one another, before both saying "It's the locket!"

"This is just the kind of break in the ice we've been waiting for. When Katsuki's innocent little daughter...uncovers the secret of that locket... she's going to have lots of questions. And who'll be right there with all the answers?"

"We will." Chronostasis says and Overhaul nods, "Exactly! She'll be the perfect tool for the sea kings undoing."

"And I'll get to be big again." The shark says happily. While Overhaul continues to look at the projection, "Finally I'll succeed at the one thing Shigarali never could."

"Really,really big again!" The shark says, in his own little world, "Total domination of the seas!" Overhaul used his hand to make the projection disappear before swimming off,

"I'll be huge!" The tiny shark didn't even care about Overhaul plans, he just wanted to be big again.

Now back at the castle or should I say outside of the castle, Aizawa and Katsumi were sitting on the rock, the princess looking at the locket before placing it in her bag, "Katsumi, please. If your father ever found out you'd been swimming out here..."

Katsumi sighed, "know,I know. He'd flip. I had a thought here. Now, where'd it go? Hey, Aizawa... what's my dad got against the ocean anyway? I mean, how could there be anything wrong with something so...wonderful?" She asked, making Aizawa have flash backs where Katsuki said something similar about the land.

Katsumi then leaned in close to the crab and whispered, "You know what? Sometimes I even pretend I have fins. I wish I could tell my dad how I feel. But he'd never understand. I can talk to crabs, but not to him." Hearing this causes the crab eyes to widen. She pretended to have fins? She has never said a word about this to her father? Oh. My. God! She really is her fathers child. But expect there was a difference. Katsuki would pretend to have legs. That was the only difference. Katsuki never talked to his father about his wants and now his daughter was doing the same.

Now Denki, who had happened to fly onto the rock at the right time suggested something, "Wait a minute. It just hit me. How 'bout you tell Kacchan... how you really feel? I mean he might actually be able to understand you."

"Oh, yes, by all means. Just waltz right in and tell him you been out here...swimming in the ocean! We could all just have a big party." Hearing the word party caused the princess eyes to widen and she gasped, "The party! Oh dad will not be happy if I miss that!"

"Say, that reminds me of somethin'." The bird says, feeling a sense of deja vu. Katsumi says a quick goodbye to Denki before swimming towards the wall, Aizawa not far behind. They swam underneath the castle to a part where she could leave and enter. All she had to do was move it. She quickly did before picking up Aizawa and putting him into her bag. She looked around and saw her father walk out. She ducked down and hid, before quickly running in the castle when she was sure her father wouldn't see her.

On the way she bumped into a young noble, "Woah!" The young noble almost fell, but was caught by his friends, "Oh, Your-Your Highness." The boy says, turning to face the young princess. The only two nobles one female and another male watch look at the princess curiously, "Sorry. My fault. I gotta go. Can't go to the party without shoes." She says while the boy noble nods. Once out of war shot the three make fun and laugh at the princess. She was odd, a weird tomboy princess.

They even thought the king  and queen was weird, not that they would ever say it to their faces of course. After all...who want to deal with the king? A man who would not mind hurting a child for hurting his daughter or wife.
