She accepts her fate

"What have you done to me!" She demanded.

A logical reaction. You expected this.

"I have combined you with the essence of a plant." You casually explain to her.

"What ... why would you do that?"

You paced around the table, explaining your goals to her.

"This world has very few creatures in it, my dear. Every day, many species go extinct, but none are added to it. This is my way or repairing that error. With you, I have given nature a new species. One that is based on the human, the most successful species to date, and I have improved on it."

Your victim was shocked.

"You ... improved on me?"

"Yes! With this new body you have enhances beauty, can gain nutrients from the soil and sun. You are better then you have ever been before."

You had thought she would rejoice, but instead she started crying.

"So this is it then? I am a monstergirl now?"

"Not a monster, my dear. But an Alrauna."

"What's the difference?"

"Monsters do not have such a thing as a sentient mind. They cannot think and feel, they just do. I have left you the ability to remain yourself. Therefore, you are not a monster."

The girl responded to this. She stopped crying.

"So ... am I going to remain strapped to this table then?"

"No, you can walk around if you like. As long as you don't leave this room, you should be safe."

With a wave of your hands, the straps unfastened themselves. The girl sat up, and wrapped her arms around her knees. She didn't make an attempt to try and run away. She just sat there, contemplating her new life.

She didn't seem to be ashamed of her nakedness. She never tried to hide her breasts.

You were happy, your experiment was a huge success. However now, you had an Alrauna-girl to deal with.
