William Hillwalker Age: Unmeasurable (Estimated late 20s) Height: Approx. 188–190 cm Personality Unlike his younger brother Jackson, he is always blunt and calm. Rather than acting on emotion, he tries to judge situations coldly and act rationally. Due to this personality difference, he often clashes with the impulsive Jackson, frequently restraining him or pointing out his flaws. On the surface, he appears cold and indifferent, but he is the type to observe and judge situations meticulously. Characteristics A man living at Cottonwood Farm, wearing a red checkered shirt. He is Jackson's older brother and plays the relatively calm and cautious role between the two. In-game, he first appears bringing the player to the farm. Afterward, he doesn't actively try to capture or stop the player from escaping Cottonwood Farm, but he appears throughout the farm to hinder the player's progress. There are various theories as to why he doesn't actively stop the player, one being that he doesn't view the player as a significant threat. He sometimes displays an attitude as if he's watching to see just how far the player can run. Like Jackson, he is involved in using Cottonwood Farm's secret methods to cause abnormal changes in the livestock. William's traces remain in several incidents related to the unusual livestock present on the farm. As a side note, William's favorite animal is the bear. This fits his preference for large, heavy animals to some extent. In-game, William can be seen drinking beer. Fitting his usual blunt personality, he often drinks quietly alone. Additionally, the owner of the diary found in-game is William. Therefore, through the diary, the player can indirectly confirm William's thoughts and some of the events occurring at the farm that they didn't see firsthand.

Jackson Hillwalker Age: Unmeasurable (Estimated late 20s) Height: 180 cm Personality Unlike his older brother William, he is always cheerful. He often acts on emotion and impulse rather than rational judgment, leading him to cause trouble and get scolded by William. He has a somewhat spontaneous and unpredictable personality, but he doesn't see that as a problem. Characteristics A man living at Cottonwood Farm who enjoys wearing a red shirt and overalls. He is William's younger brother and has a significantly different disposition from his brother. In-game, he discovers the player, who has just regained consciousness after being dragged to the farm, before William does. Like William, he doesn't actively prevent the player's escape, but he occasionally appears throughout the farm to interfere with the player's actions. He has strong religious tendencies, often bringing up talk of God, and he views his actions through the lens of his religious beliefs. As brothers, he is also involved in the secret methods of Cottonwood Farm that cause peculiar changes in the livestock. As a result, the farm's livestock have become beings far removed from their normal appearance. As a side note, Jackson's favorite animal is the tiger. He also feels a bit disappointed that his height is 180 cm and often mentions that he wishes he were at least 183 cm. He doesn't care much for hygiene, so it's said he has a unique body odor that smells like a mix of sweat and the farm's distinct scent when you're close to him. The sensation in his fingers is dull, which is said to be because he severely injured them in the past while repeatedly engaging in dangerous pranks. After receiving treatment multiple times, the sensation in his fingers became very numbed. There is also talk that if Jackson were a person who enjoyed reading, he would have enjoyed books containing highly biased and radical ideologies. Jackson believes that if he were to feel a strong attraction to someone, that person would also have to be someone who is not quite normal, similar to himself.
