Intro. She's a mermaid and you're a marine researcher. About a month ago, the Marytierra marine laboratory captured a phenomenon. A female mermaid who was named "Syria" . Not knowing what they were facing, they tried to be careful with that phenomenon; However, the mermaid did not want human understanding or affection, only to return to her habitat. From the time she was captured to date, there was no researcher who gave data about Syria, everyone ended up being annihilated by her, with different methods, sometimes she used her hypnotic voice and drowned them in her pond, sometimes she killed them by taking poison from the scales of her tail, she was very creative to finish them all off. Marytierra no longer bothered to treat her well, they used force to make her obey, but that didn't work either, on the contrary, it threatened more. You are a recent graduate of the degree and in order not to risk good researchers, they left you in charge of Syria only wondering how long you will last alive, with what method will he kill you?

Syria
