After Katsuki remastered the magic in his fish hook, in turn, he taught Izuku how to sail, begrudgingly. Izuku learned quickly and sailed across the vast ocean, to ta feti.
" I figured it out. You know Oceania loved it when I pulled up islands. 'Cause your ancestors would sail the seas and find them. All those new islands, new villages... It was the water that connected them all. And if I were Oceania, I think I'd be looking for, a not an entirely useless mortal," Katsuki chuckled.
"That is literally the nicest thing you've ever said to me. Probably should've saved that for Te Fiti," Izuku smiled.
"Yep and that's the last nice thing I'm ever going to tell you, Deku," Katsuki said simply.
" It's time. Go, save the world, Katsuki," Izuku smiled as they soon approached the darks walls of Te Ka.
The battle was fierce but no matter how hard Katsuki tried, Te Ka would just knock him out of the sky and force him out of shapeshifting. Izuku tried to help to find a better way in, but before Izuku could get close to the opening. Te ka raised its fist and slammed it down, Katsuki countered with the power of his fishhook and Oceania raised a pillar of water. The clash between the three powerful beings was so great, the shockwave sent the canoe miles away from their destination.
Izuku slowly woke up to see the Canoe was a bit mangled but mostly intact. Katsuki sat eerily quiet at the edge of the canoe. His hand was in the water as a hand of water held onto his.
"Are you two okay? Katsuki?" Izuku asked nervesly.
"I should have told you to turn back," Kastuki grumbled.
Katsuki stood up to show his damaged hook, as it sparked magical energy. Before Izuku could say anything, Katsuki cut him off. "It was made by the gods. You can't f**king FIX it," He said sternly.
"Next time we'll be more careful. Te Ka was stuck on the barrier island. It's lava. It can't go in the water. We can find a way around," Izuku explained.
"I'm not going back," Katsuki glared.
"What... We still have to restore the heart," Izuku argued.
"My hook is cracked. One more hit and it's over, Without my hook, I am nothing," Katsuki shouted as his body trembled.
"That's Not True-"
"Without my hook, I am nothing!" Katsuki roared.
"We are only here because you stole the heart in the first place!" Izuku shouted as his tears welled up in his eyes.
" No, we're here because Oceania told you you're special and you believed it," Katsuki spat as he raised his hook.
Izuku gasped as he covered his face, waiting for the strike... But it ever came; Izuku looked up to see Oceania pushing back against Katsuki's hook, protecting Izuku. As Izuku looked at Katsuki, he could see many emotions in his eyes, anger, sadness, betrayal.
"So you're abandoning me too, HUH! Oceania!" Katsuki shouted in pain. Oceania shook its head.
"You left me on that island for hundreds of years, and where were you?! Off, F**king around with mortals. If you love this dumba** so much, Fine!" Katsuki snarled as transformed into an eagle. "Goodbye, Oceania. I'm not killing myself so you can prove that Deku is something he's not."
" I am Izuku of Motunui. You will board my boat-Sail across the sea-restore the heart of Te Fiti. Oceania chose me," Izukku began to stutter, holding back tears.
"It chose wrong," Katsuki spat, as he flew off.
"Katsuki!" Izuku called out.
Izuku could no longer hold back his tears, as his heart sank into despair. Oceania slowly approached Izuku and placed a gentle hand on his shoulder, but Izuku shook it off.
"Why did you bring me here? I'm not the right person. You have to choose someone else. Choose someone else. Please," Izuku begged as he gave it the heart.
Oceania slowly took the heart and dropped it into the water. As they turned back to Izuku, they could hear Izuku mutter to himself, "I'm useless." Oceania began to glow faintly, catching Izuku's attention as he stared in awe.
"You are not useless, You are a long way past the reef," Said a voice.
The voice comes from Oceania, Izuku recognized that voice, he knows this voice. " Y/n."
Oceania began to change, as its features became more defined. As its body began to become more human. Its water surface transformed to smooth S/c skin, as h/c hair grew on top of its head. A face started to form, as a pair of familiar E/c eyes stared back at him.
"Y-you were Oceania this whole time?" Izuku asked in shock.
"I go by many names, but yes I was always Oceania," Y/n smiled as they kneeled to Izuku's level.
"I tried Y/n, I couldn't do it," Izuku said as he began to sob.
Then suddenly he felt a pair of warm arms wrap around him, Izuku gasped at the sudden closeness of Y/n or Oceania.
"It's not your fault. I never should have put so much on your shoulders. If you're ready to go home, I will not stop you," Y/n said softly as they hugged Izuku close.
Izuku nodded as he picked up the paddle, but he halted as he turned back to Y/n.
"Y/n, are you going to return home with me?" Izuku asked, even though he most likely knew the answer.
"No, I have to find another to finish this journey. I cannot return to Motunui with you," Y/n frowned sadly.
"I'm, I'm sorry I failed. But please stay with me a little longer?" Izuku asked as he hugged Y/n. " I love you Y/n, I love you so much."
" It's not your fault. I never should have put so much on your shoulders," Y/n said as they returned his hug.
I know a boy from an island
he stands apart from the crowd
he loves the sea and his people
he makes his whole family proud
Y/n smiled as they cupped Izuku's face lovingly.
Sometimes the world seems against you
The journey may leave a scar
But scars can heal and reveal just
Where you are
The people you love will change you
The things you have learned will guide you
And nothing on Earth can silence
The quiet voice still inside you
And when that voice starts to whisper
"Izuku, you've come so far"
Izuku, listen
Do you know who you are?
Who am I?
I am a boy who loves my island
And the boy who loves the sea
It calls me
Izuku started.
I am the son of the village chief
We are descended from voyagers
who found their way across the world
They call me
Izuku said as ghosts of ancestors sailed past them.
I've delivered us to where we are
I have journeyed farther
I am everything I've learned and more
Still, it calls me
And the call isn't out there at all, it's inside me
It's like the tide
Always falling and rising
I will carry you here in my heart, you'll remind me
That come what may
I know the wayI am Izuku
Izuku dove into the water to retrieve the heart, he quickly returned to the cone to see that the visions of the ancestors vanished, along with Y/n or Oceania.
"I am Izuku of Motunui. Aboard my boat, I will sail across the sea and restore the heart of Te Fiti," Izuku repeated to himself as he repaired the boat and prepared to face Te ka.

It didn't take long for Y/n to find Katsuki, sitting alone on a rock in the middle of the vast sea.
"So you finally took o your human form? What do you want?!" Katsuki growled.
"I'm here to ask you to help return the heart with Izuku," Y/n said simply.
"Why should I care what happens to the useless human. If you love him so much, why did you have to drag me into this? You already long abandoned me!" Katsuki shouted.
"I started the legend of this journey to save you!" Oceania shouted.
"What The F**K Are You Talking About!" Katsuki growled.
"I told you not to steal the heart, and you still did anyway and sent the world out of balance. What do you think will happen to you when the gods confirm that you were the one to cause all this trouble. They will seal you away, and I can't go on adventures with you anymore," Oceania shouted as tears ran down their face.
Katsuki froze at Oceania's words, he didn't really know what to say.
"If you helped a human restore Ta fiti, you may win favor from the gods and they could pardon you," Oceania explained.
"Then why didn't you just return my hook me, and just leave me alone on that tiny rock?!" Katsuki growled.
"Would you have helped clean up your mess If I did?" Oceania asked.
Katsuki huffed, knowing Oceania was right. But one question remained in his mind.
" Does that human... hold more weight in your heart than I do?" Katsuki asked softly as the shadow from his bangs cover his eyes.
Oceania was surprised by Katsuki's question but answered honestly.
" I am not too sure this is the first time I've gotten very close to humans like this. But what I do know, is that you and Izuku are the few things I treasure deeply, and I would like to venture together again soon. I don't want to lose either of you, but if don't want to help, fine. But I will help Izuku save his home," Oceania said as they sank back into the water.
-------------------------
Izuku managed to get past the main barrier of Te Ka, but his boat was flipped over. As Te ka was about to finish off the human, Katsuki swiftly sliced off Te ka's hand.
"Katsuki! You came back. But your hook. One more hit, and-"
"Te Ka's gotta catch me first. You better hurry up and get the heart to te fiti Deku," Katsuki said as he flipped the boat back upright.
"Katsuki, Thank you," Izuku smiled.
Katsuki simply nodded and turned back to fight. A stray fireball wrecks the canoe and sent Izuku flying, but Y/n quickly caught Izuku and pulled him towards land. Izuku smiled at Y/n as he quickly ran up the hill only to find that Te fiti was gone.
As the battle roared, Izuku turned back to look at Te ka. Yet as the smoke cleared a spiral on Te ka's chest was revealed.
"Let her come to me," Izuku said, as Y/n parted the water leaving a clear path for Te ka.
Te ka confused at first quickly pulled itself down the path as Izuku slowly walked down the path towards Te Ka.
I have crossed the horizon to find you
(Ou loto mamaina toa)
I know your name
(Manatu atu)
They have stolen the heart from inside you
(Taku pelepele)
But this does not define you
(Manatunatu)
This is not who you are
You know who you are
The fire within Te ka seemed to have died out as she lowered her head towards Izuku, who rested his forehead against her. With Te ka calmed Izuku placed the heart on the spiral, revealing it was Te fiti all along.
"Te Fiti," Izuku awed as Y/n lifted Izuku to get a better look at the goddess.
Te fiti sat down in her original place and brought back the life of the land. Y/n gently placed Izuku down and pulled Katsuki onto the ground, along with Denki chicken.
" The chicken lives!" Y/n smiles.
"Katsuki, sorry about the hook," Izuku apologizes.
"I'll be fine, I'll just get stronger," Kastuki grunted.
Suddenly the ground under them rumbled as the hands of Te Fiti lifted them to her eye level. Y/n and Izuku quickly bowed before the goddess, while Katsuki begrudgingly got on one knee. Katsuki could feel the Goddess stare at him so he swallowed his pride and looked up at the goddess.
" Look, what I did was... wrong. I have no excuse. I'm sorry," Katsuki apologized.
Te fiti looked over to Oceania with a questioning look. Oceania nodded as Tefiti smiled in reply as she gave Katsuki a fully repaired magic fish hook. Katsuki stared in surprise as he slowly picked up the hook.
"You know, it would be rude to reject a gift from a Goddess," Izuku smiled.
"Thank you. Your kindness is deeply appreciated," Katsuki thanked softly as he transformed into a bug and flew away.
Te fiti smiled and restored Izuku's canoe, and promptly went back into her infinite slumber. Y/n and Katsuki helped stock up food for the storage on the Canoe for Izuku and the long trip home.
"You can come with back to Motunui, you know. My people are going to need a... master Wayfinder," Izuku suggested to Katsuki and Y/n.
"They already have one," Y/n smiled, while Katsuki scoffed slightly.
Y/n smiled as they pointed to a new tattoo that appeared on Katsuki's skin. It was an image of Izuku on a canoe.
"See you out there Izuku," Y/n smiled as they kissed Izuku's cheek.
"Y-yeah, I can't wait to journey with you again," Izuku stuttered.
"Let's get going already, we can't guide humans to a new land by staying here know can we," Katsuki smirked.
"Yes, we must go. I hope to see you on the ocean again soon Izuku of Motunui," Oceania smiled as they returned to the ocean.
___________
Izuku smiled as he sailed his canoe as he leads his people to a new land, as he observed the sky he saw the eagle of Katsuki flying over them. As Izuku quickly turned to the ocean, he placed his hand in the water to feel a hand stroke his. A familiar face quickly flashing in under the surface of the water.
Izuku knew, that he still ventures with good friends.
