"An eternal soul, huh…" The Witch of the Sea murmurs. "You really want one, don't you."
Izuku nods.
"If humans can get one, why can't us merfolk?" The young merman says.
The Sea Witch smiles.

"You /what/?!" Katsuki screeches. "You… you… you idiot!"
"Quiet down." Izuku mumbles. "Someone might hear us."
"Let them," Katsuki growls. "Your stupid tail dragged me out onto some shitty reef in the middle of the night to tell me some pretty disturbing news."
"I shouldn't have even told you what I did." Izuku mumbles. "If I'd known you'd react like this."
"How else did you think I'd react!" Katsuki screams. "You sold away your precious lyre to the fucking Witch of the Sea! So that, what, you could gain the ability to transform into a human whenever you feel like it?!"
"I can only transform into one at night." Izuku replies.
"THAT'S NOT THE POINT!" Katsuki yells. "GOD, YOU'RE…. YOU'RE UNBEARABLE…!"
Izuku lowers his head.
"I'm sorry."
"Izuku. /I'm going to kill you./"
"It wasn't a bad deal!" Izuku insists.
"What do you mean it's not a big deal, you numbskull! Your lyre… your lyre was…"
Katsuki pinches the bridge of his nose.
"You were good at it. It was the one thing you were truly good at. Now you're useless without it."
"I have a good voice, though." Izuku says quietly.
"But you're not a singer, Izuku!" Katsuki shouts. "You're an instrumentalist. You were one of the best in Our orchestra and in our Kingdom. And now… you sold it all away so that what?? You could gain the ability to turn into a freak?!? HOW COULD YOU??"
"Katsuki, wait!" Izuku cries out as Katsuki dives back into the water. "I'm… I'm sorry…!"
"Fuck. Off," Katsuki says, his final words before he descends back into the Sea.
