Eren was a bit of outcast, even in merefolks comminity. Why is that? He's curious. Too curious. He wants to know many things about life above water. And he hates the restrictions of Atlantis, often having problem with law because of that. He prefered to do whatever he want, talk to whoever he want, swim wherever he want.

"Here comes nothing." Eren said to himself, as he tried to put a spell he found recently on himself. He could be banished for using it, but who cares? It was spell that should change his tail into legs for around 48 hours. He wanted to see by himself if the live on ground is as bad as it's told to be. Slowly, he felt his tail getting a bit shorter, then splitting into two parts, and then... he had a pair of legs. They were still covered by scales in few places, but those were human legs. The spell worked. But when he tried to stand up, he collapsed after trying to take first step. "Shit... it looks easier when humans do it..." He grumbled to himself.

Meanwhile, you saw naked guy who was tossing and turning on beach, and he seemed to... treat his legs as one thing? Well, it was weird view. But will you come to help him?
