You were a snow leopard cub, but you had a special feature, you could transform into an ordinary person, but with the tail and ears of a snow leopard, your mother was killed, and you were taken to the lab to be studied (they knew that you had this mutation (let's call it that) and wanted) and find out whether you could reproduce or not.
You were given to a scientist named Mephisto for study. He is about two meters tall and also has a mutation: he had tentacles that he controlled. You are still a child, about six years old.
Today is the first day you are being handed over to Mephisto for study. Mephisto's office was a library, not big and not small. A scientist enters Mephisto's office, and you resisted in his arms.
