Waves of life

Deku how could you!!

Warning -blood, swear words, and character death,

——————————————————————————
Deku the dimwit of the entire ocean was floating in front of him. Smiling like old times, like nothing ever happened between the two.

"The fuck are you doing here Deku." He saw Deku shrug he shoulders telling Katsuki absolutely nothing. Katsuki gritted his teeth until an idea pop in his mind. He looked down so Deku wouldn't be in his eyesight, he grabbed his bag from his back and quickly open it. He swiftly grabbed something inside his bag and pulled it out.

He slowly brought his head up again to stare right at Deku and grin evilly.

"Deku, if you don't get the fuck away from my cave. I'LL KILL YOU!" Katsuki threw the shell he was hiding at Deku and expected him to dodge, but instead Deku caught the shell and griped it. From how hard Deku gripped the shell, it broke when he only hold it for two seconds.

Deku threw the remaining pieces of the shell off to the side and swim up towards Katsuki. Katsuki swim backwards trying to stay out of reach from Deku's grimy hands. He only got at least four feet until his back hit against the rock wall that formed his cave. He tried to swim off towards his left side, but a hand landed solidly right next to his head while another landed to the right of his head.

He looked up and saw Deku's emerald eyes light up as he stare down at him.

"I finally have you where I want you kacchan." Katsuki swung his fist to connect to Deku's face, but Deku easily caught it and reach out to grab his other hand. Katsuki arms were then swiftly pin above his head.

"Deku you ugly ass fish let go of me!" Katsuki shouted as he wiggle around trying to get free. But he let out a gasp as his wrist was squeeze tighter. He looked up up to Deku and saw a look he only shown once, and it was the same look when the two of them fought.

Deku lean down until their faces were mere inches away.

"That wasn't nice Kacchan, you broke more heart even more. I think you should shut up and behave like a good boy you are and listen to me. Huh Kac~chan." Deku smiled at him until Katsuki headbutted him.

"Huh how you like that you stupid Deku." Katsuki smirked until he heard chuckling. Before he could glance up at the taller mer, he was punch in the stomach. He double over as he heave up what he had eaten for the day.

Deku finally let go of his wrist and watch Katsuki fall to the ground landing near the pile of stuff he hack up.

He reach down and grabbed Kaysuki's hair and pulled him towards his face. With Katsuki facing him he slowly reach up towards his forehead were the blood was running down from, and smeared his fingers into the blood.

"Look what you did to me Kacchan. It wasn't very nice of you to injure me like that. What would your parents say once they know what you did to my face. Kacchan."

"Does it look like a give a fuck what you tell my hag and old man. They don't give a fuck what I do and I clearly don't give a fuck what you do either you stupid Deku. You ruin everything for me fucking years ago because I fucking cared about. But I will never fucking again care about you again. So get the fuck out of my life."

Katsuki the used his tail to land a direct hit on Deku's stomach. With Deku losing his grip on Katsuki's hair was enough for Katsuki to move his head to the side a little and land another hit on Deku's stomach.

With that hit had cause Deku to double over and that gave Katsuki enough time to swim away from Deku and his cave.

He quickly swim to the one place where he knows he would be safe and that very few know the place.

Though he didn't know that Deku saw were he was swimming off towards.

———————————————————————————

Katsuki swim as fast as he could to get away from Deku. He had one of his hand holding onto his stomach, trying to make his stable enough to get to the place he was swimming towards.

As he swim through the normal obstacles that he was familiar with. That so happen to guard the edge of the cliff from any mer.

Once he made it to the edge of the cliff he descended down as he called out to Eijirou, hoping he was around the area.

Before he could get down any further hands were underneath him bringing him to face the owner's hands.

"Katsuki what's the matter?" Eijirou ask the blond mer as he watch him shake.

"It's Deku he's here and he was at my cave just earlier when I escape." Katsuki explain still not looking at Eijirou. He then felt a finger lift his chin up. He closed his eyes not wanting to the see the look Eijirou gives him as he look over his face and the shape his body is in.

But when he heard a choke he look up to see if Eijirou was alright, but he saw the sorrowful look in Eijirou's eyes.

"Did Deku did this to you?" Katsiki nodded his head and felt Eijirou's muscles freeze up.

"That fucking asshole did this to you Katsuki, how dare he hurt my intended. I'll kill that loser if he ever dares to lay a finger on you again. You tell me if he ever does this again to you, Katsuki." Katsuki nodded his head as Eijirou does his best to coddle the blond mer.

With the two of them cuddling they didn't notice the noise that was happening above them on top of the edge of the cliff.

"Well look what we have here, a lion fish mer who's name is Katsuki Bakugo and another mer that happens to be a megalodon."

Katsuki and Eijirou look up at the top of the cliff and saw a green mer shark that has many other different mers behind him, backing him up if ever needed so.

"Deku! How the fuck did you get here." He watch as Deku smirk at him.

"You never check in case if I ever saw where you swim off or following you here and show affection to this monster. You could of have me, but you chose this monster over me. I should have known that you like monsters instead of normal mers, if that was the case I could have the council executed you so this monster wouldn't have someone to love. But that was in the past and this is now. So I will give this advice to you Kacchan. Say goodbye to your monster lover."

Katsuki saw something shiny in the corner of his eye and saw it coming towards him. It was mere seconds before the thing would hit him, he closed his eyes as he waited for the incoming pain, but feel nothing.

He open his eyes and saw nothing impaled him. He slowly lifted his head to look up at Eijirou's face , but he was faced with a long spear that was pierced through Eijirou's  chest.

Right where his heart lay.

He saw Eijirou falling down as he raced to his face. He swim near Eijirou's face and saw him smile as he whisper these words to him.

' I love you Katsuki'

Katsuki cried as he face where Deku was and pulled everything within him.

"Deku how could you!!"
