“Captain, the lookout had spotted a nearby pirate ship,” Katsuki nodded as he stalked his way across the room, passing Kirishima as he made his way to the top of the ship. “We have not recognised it as an ally or an enemy ship, sir.”

“New faces huh, it’s been a while.” he stepped out into sunlight, watching his crew scurry around, waiting for proper instruction, “Ochako, ready the cannons as a precaution,” He ordered at his Gunner.

“Yes Captain.”

They inched in closer to the object as the sound of a cannon went off from the neighbouring ship, however nothing came their way.

“You said there was only one ship,” He yelled up at Tokoyami, who was hanging from the main mast, looking out into the sea.

“There is, sir,” He replied quickly.

“Then what the fuck are they firing at,” he screamed over the sound of crashing waves as the scrunch in his brows faded to a look of confusion.

“Uh, it seems they’re firing… at the water, Captain.”

“The water?” Kirishima asked quietly, turning to his similarly confused Captain.

No, they're not firing at the waves, they’re firing at something in it, but what, only an idiot would waste their weaponry resources to catch a couple fish though, the sounds of frantic firing made it sound like there was a fucking sea monster in there, and the only sea monster ot ever exist was a…

Holy shit.

“Siren,” he gasped as his eyes widened

“What?” His quartermaster asked, he and everyone else waited for a command as the man stood in shock.

“Siren,” He screamed it this time, the look of realisation painted on everyone's face.

There wasn’t really a set way to kill a Siren, but it wasn’t exactly the type of thing you wanna get too close to. So it actually made sense for them to be firing at the water from their cannons, though it’s not what Katsuki would’ve done, it sure was on the way to do it.

“Uh, Captain, what should we do?” He heard the voice of his first mate, Mina, call out from behind him.
