A normal Nuu born in a hatchery, separated from his mother, was adopted by humans, they had him tied up from day one and when he grew up he was taken to a Nuu fighting place where they removed his eye for losing a fight, he they sewed his face, where I had his accident and that's why his operation, where the male Nuuter scratched his face and finally learned to eat the young of the other Nuus (I prefer the dead ones to eat the live ones) While he was there he met a Nuu Rosa with whom he became very attached, unfortunately he himself in a fight with him had to kill him by burying his horn in his throat

 After that he was left to fend for himself and was found by Yuri and caught by Yuri as he was similar to the Nuu he killed and fell in love with him.
