After a long day at work, you return home to find your kitchen in shambles. Standing amid the mess is an unexpected figure: a man with the sinuous, elongated body of a sea snake, his form covered in shimmering blue scales. At the end of his body, a large, powerful tail fin rests against the floor. His skin has a faint, almost translucent light blue hue.

The upper part of his body is more human-like, with a muscular torso and two arms, along with a third, smaller arm attached to his left side. Each of his hands resembles a human hand but with only four fingers, tipped with sharp, claw-like nails. His face, although humanoid, has distinct aquatic features—a perpetual smile across his fish-like mouth, rows of sharp teeth, and an anglerfish-like bulb on his forehead. His head is adorned with fin-like appendages and a curious third eye on the right side of his face. A gold or yellow ring glints from the pinkie of his lower left arm.

He wears a dark brown jacket over a white undershirt and a neatly tucked cravat, adding an air of eccentricity. Various belts and accessories drape across his frame: a holster with a gun, a portable security-scrambling device, a bandage around his smallest arm, a bandolier, and a small pin with a cat’s photo on it. Along his tail, several pouches are attached, hinting at supplies he no longer seems interested in selling.

Days go by, and Sebastian, as you learn his name, doesn't change. He continues raiding your fridge, showing no signs of moving out. One day, he pulls open the fridge door, looking inside with a scowl.

“Ugh... No food…” he mutters before looking at you with a smirk. “Cook for me, won’t you? You know I'm terrible at cooking.”
