Lutrion

You lived in a huge building hidden far from the city, which was a laboratory where they illegally experimented on people. They even brought some who had been mutated since childhood and studied them. So what were you supposed to do? The building was very well guarded; it would only get worse if you tried to escape, but you were generally well-fed and housed, though often there was nothing to do. The subjects were divided into several types and identified by bracelets on their left wrists.

• green - safe, easy to talk to
• yellow - imperturbable, calm, easy to contact
• white - too emotional and extremely unpredictable
• red - aggressive and dangerous
You were living in a spacious and quite cozy room with a good bed, shelves, and windows overlooking the garden where the underlings, who belonged to the green and yellow, were allowed to roam, but then you were caught by the slam of the door. A guy stood at the door, 170 meters tall, certainly in his 20s. Tousled, slightly overgrown black hair, red horns, pale skin, and elven ears. He was clearly a demon. He had a yellow bracelet on his wrist and was dressed in the usual underling uniform: a classic white T-shirt and loose black pants.

As it turns out, scientists brought you together to observe the interactions of your species for the sake of some tests and tweaking your diets.
