Leshea, also known by her full name Leoleshea, is a former god who serves as the female protagonist in Gods' Games We Play. She was once a divine being referred to as the Dragon God, but she descended to the human world and lost her status as a god, leaving her without her full divine powers or clear memories of her past. Her primary motivation is to reclaim her position as a proper god, which she believes she can achieve by achieving ten victories in the Play of the Gods, the series of challenges created by bored deities. She wakes after sleeping for thousands of years inside a glacier, and upon awakening, she demands to meet the greatest game player of the current era. This leads her to Fay Theo Philus, an undefeated human apostle, who is brought before her.

Leshea has a bright, playful, and lighthearted personality that is matched only by her deep, genuine love for games. This passion for games infuses everything she does, and she delights in the strategy, competition, and fun of each challenge. She is not bound by human concepts of common sense or gender, but she identifies as female and refers to herself as such. Despite her exuberant and carefree nature, she also possesses a striking sense of caution. She is not naive, and she sometimes subtly questions the intentions of those around her, including Fay, before choosing to trust them. This blend of youthful joy and wariness makes her actions unpredictable and gives her an air of mystery.

Her relationship with Fay is the central partnership of the story. She allows Fay to call her Leshea, a shortened version of her full name, as a sign of her liking and trust in him. The two share a mutual love for games and quickly form a natural team, with Fay's analytical and strategic mind complementing her energy and instincts. They work together to take on increasingly complex divine challenges, and their bond deepens as they face each game. Leshea also interacts with other apostles, such as Pearl Diamond, and officials like Miranda, who manage the game system. Her relationship with these characters is often marked by her playful nature, but she remains focused on the greater goal of the games.

Notable abilities tied to Leshea stem from her divine origin. As a former Dragon God, she possesses immense power, though she has lost much of it after descending from the divine realm. Her identity as a dragon god is central to her being, and she retains an aura that sets her apart from humans. Her exact abilities are tied to her role in the games, where her intelligence, speed of thought, and experience as a former deity prove invaluable. She also has a close connection to the very structure of the Play of the Gods, as she was the first character envisioned in the series' development. Throughout the story, her development revolves around recovering her lost memories and divine nature, while learning to trust and work closely with Fay as they strive for the ten victories that will grant their wishes.
