Needed backstory

So the shamchat sorta went like this: Bill bumps into Nico and messes with him a bit, then offers him a deal to get his sister back in exchange for him staying out of his way. Nico said no after some debate with himself and so Bill put him in a perpetual nightmare of his sister's death. Bill also took his sword and left him there, on the sidewalk, and he never told Nico his name just that he's a dream demon.

"N-no!... No…" He whimpered and sat up, bringing his knees to his chest. He closed his eyes and cried, but in true torture fashion, the scene was crystal clear no matter what he did.

"D-dam demon." He crawled away, though it did nothing with the images that followed him. Soon he forgot all thoughts of him though, only thinking about the death of his sister before him.

B-B-Bianca…. Bianca! I-I'm so s-sorry… Bianca…" He sobbed, giving up on moving. Little did he know, a certain sea king's son was walking home from school, and heading right towards him.
