Louis/History

Background
Louis' birth parents are unknown. When he was 5, he was brought to the tower to be raised as livestock and locked up with other herbivore children in the Black Market for the purposes of being eaten by carnivores. He was tattooed with a "4" on the bottom of his right foot.

Louis also had two friends, a female rabbit called Number 9 and a male alpaca called Number 3. Through a series of lotteries, children herbivores would be taken to waiting customers. None of the children were taught how to speak or read, as seen by the sounds that Louis makes in attempts to communicate.

Oguma approaches his cage, stating that he will buy Louis, much to his displeasure. Once in the elevator to leave, Oguma introduces himself and reveals that he suffers from a birth defect that prevents him from producing children. He states that he plans to raise Louis as his own son due to Louis' lack of own parents.

As a test of his abilities, Oguma opens the elevator door and pushes Louis into a room full of hungry carnivores with only a knife to protect himself. At first, the carnivores question the situation then slowly approach Louis as the small fawn holds the knife up to his own neck, screaming.

Oguma quickly pulls Louis back into the elevator and composes himself. He states that Louis is "exactly what he's been looking for" and opens the door again to reveal a shining sunset. He hugs Louis, claiming that he will be able to turn his pain and suffering into strength.

After being adopted, Louis grew up in an environment where displaying emotions and failure were prohibited. Since the tender age of seven, Louis was groomed by his father to be the next heir of the Horns conglomerate. Though Louis performed well academically and wasn't abused, Louis didn't receive very much warmth from his adoptive father. Thus, forming Louis' steely personality.
