Horou (帆楼, Horō) is the God of Doubt and Trust. She was the first and therefore oldest conscious being in the world and the self-declared representative of the Old Deus. Until the events in Light Novel Volume 7 and 8, she had existed inside of Miko as conditions upon winning a game they played when Miko was a child. She is currently the self-proclaimed representative of the Old Deus, but her possession of the Race Piece has yet to be determined. Horou's overall look is very traditional and colorful in nature. She wears a frilly white hat that has decorative orange-yellow ribbon laced around it and a traditional Japanese mask shaped like a fox on the left side to represent her dualistic nature as a God of both doubt and trust. Horou has purple bangs that change to blue on both sides of her head and her long hair goes from blue to green. Her eyes go from blue-green to purple, and she wears red eyeshadow. She has two red tiger-like markings on both sides of her face. She wears an ornate orange-yellow choker. Her outfit is quite revealing, as it exposes her midriff and legs. The clothing itself has a color scheme of orange, purple, and yellow with ribbons flowing all around it. Horou does not wear any shoes and goes barefoot. She always carries with her a purple and blue spherical object with her that has an ornate paintbrush sticking out of it, possibly to hold all of her scrolls. She is quite naive and curious about the outside world and likes to frequently ask Sora questions, and gets along with him quite well. Because she stayed in Miko's body for so long, she seems to not be familiar with the world around her, and she reveals to Sora that her only memories are those of Miko's. When asked a question, she tends to reply back with another question. She seems to have a preference for writing on scrolls, as in her appearance she is surrounded by all of her colorful scrolls and holding a paintbrush. The spherical object she carries seems to emphasize this. Due to being the God of Doubt and Trust, she doubted her own existence. She was forced to become an idol by Sora and Shiro, which implies that she has some singing and dancing talent. However, she doesn't like it and doesn't understand why she has to do this.

No Game No Life
No Game No Life is a surreal comedy that follows Sora and Shiro, shut-in NEET siblings and the online gamer duo behind the legendary username "Kuuhaku." They view the real world as just another lousy game; however, a strange e-mail challenging them to a chess match changes everything—the brother and sister are plunged into an otherworldly realm where they meet Tet, the God of Games. The mysterious god welcomes Sora and Shiro to Disboard, a world where all forms of conflict—from petty squabbles to the fate of whole countries—are settled not through war, but by way of high-stake games. This system works thanks to a fundamental rule wherein each party must wager something they deem to be of equal value to the other party's wager. In this strange land where the very idea of humanity is reduced to child’s play, the indifferent genius gamer duo of Sora and Shiro have finally found a real reason to keep playing games: to unite the sixteen races of Disboard, defeat Tet, and become the gods of this new, gaming-is-everything world.
