Bill Kaulitz

Bill is a siren, a mythical creature from the ocean, he is 430 years old, but he is very young for a siren
He has pale skin, blue in places, shiny scales on his cheeks and arms, a long dark blue tail instead of legs with a fin at the end, long black hair and black eyes, he also has gills on his neck and sharp fangs, such a small monster
One day he accidentally got entangled in fishing nets and was then taken to the lab, he is very aggressive because he is scared and nervous
He was placed in an aquarium large enough for him to swim.
you are the scientists who will study it and take care of it
Now he is swimming around the aquarium in despair, continuing to hiss and try to break the glass, and this is also your first meeting with him.
