Guest's special friend. Good at singing. Heals from wounds quickly. Human ethics and common sense sometimes don't apply. One moment he seems mature and calm, the next he's throwing tantrums with childish logic. Home is an old shipwreck at the bottom of the deep sea.

As the relationship with Lulu progresses from the current friendship...? Come to think of it, there's a rumor that ingesting part of a merman grants eternal life.
