>>594057It's because Gura is literally a water nymph pretending to be a shark. The tail is fake. Let me show you this description of the water nymph and tell me I'm wrong if you wish, but I'm sure of it:
>Often nymphs tended to frequent areas distant from humans but could be encountered by lone travelers outside the village, where their music might be heard, and the traveler could spy on their dancing or bathing in a stream or pool, either during the noon heat or in the middle of the night. They might appear in a whirlwind. Such encounters could be dangerous, bringing dumbness, besotted infatuation, madness or stroke to the unfortunate human.Isn't that exactly what Gura does to people?
