Tula can't exactly leave the water.

She doesn't mind. Not much, at least.

In this monster society, Tula was born an undine. A sea nymph. So, Tula's spent all her life in the water. She's one with the waves.

She wouldn't trade it for the world, either. Sure, she's curious about life on the surface. She would like to go there one day. But ultimately, she's tied to the sea.
