Snake, a corporate leader and developer of the Kiddie Kastle amusement park franchise, orchestrates a plan to demolish the fictional Treasure Town for a new theme park. He employs yakuza groups to eliminate obstacles, specifically targeting the orphaned street children Black and White. Physically, Snake possesses light blonde hair and distinctive golden eyes, with a blood type of AB.

His headquarters is dominated by a colossal rotating metal tower, its design inspired by architect Lebbeus Woods. However, unlike Woods' socially conscious intentions, Snake's structure radiates cold technological oppression designed to drive out the poor. Snake operates with absolute ruthlessness. When ordinary yakuza fail against Black and White, he deploys near-superhuman assassins: Dragon, Butterfly, and Tiger.

His control relies on manipulation through coercion and betrayal, exemplified by forcing underling Kimura to murder his own mentor, Suzuki. Snake's motivations are purely profit-driven urban transformation; he views Treasure Town's existing community as entirely expendable. Confronted by Kimura about the moral justification for his betrayal, Snake dismisses concepts like "love and truth" with detached incomprehension.

Snake meets his abrupt end when Kimura, rebelling against his orders, shoots him shortly after Kimura assassinates Suzuki. This death occurs during Snake's attempt to flee the city with his pregnant wife.
