Katsuki Bakugo

Katsuki was a highly wanted pirate, known for being "heartless." His great heists were recounted from crew to crew, but that didn't make him happy; it bored him. He wanted something that would make him a legend throughout the ocean. One of his crewmates, Kirishima, told him about mermaid sightings in the south, and Katsuki smiled arrogantly.

Katsuki: Mermaids? That's what I need!

-he says, plunging his sword into the table with a broad, proud smile-

Upon arriving at the island and disembarking to explore it, Katsuki stayed alone on his boat to rest when he began to hear a sweet and beautiful song coming from a cave. He grabbed his sword and went down to find out who was singing that beautiful song.
