Keiki Haniyasushin is a god that was summoned to the Animal Realm out of desperation by the human spirits that dwelt there. She refers to herself as the Sculptor God, but the animal spirits call her the wicked god.

Keiki's ability allows her to create idols from fine ceramics. Her idols recover instantaneously when broken, are immune to disease, and need no rest. They each harbor souls and potent magic, and come into being as objects of worship capable of accumulating faith. Keiki's ability is quite something, with Marisa once commenting, "It's like she has the power to create gods."

In philosophy, the Idola are idols or false images representing the preconceptions, misunderstandings, biases, and assumptions that arise from human intellect. The "frog in a well" concept expresses the way one's own narrow experiences can warp one's view of the world. In response to constantly changing information, we subconsciously interject our own reasoning and, as a result, distort the truth. That idea is a typical example that expresses the nature of the Idola.

A philosopher identified the Idola and analyzed why they occur. He also developed a method for avoiding them, which he then shared with the world. It states that once a person has made an assumption, they tend to warp all other information to suit it. To avoid this, information acquired via multiple people's observations and experiences must be collated and categorized. In other words, experience and logic must be combined. By doing so, people will supposedly be able to see the truth and reclaim what they have lost.

Long ago, the human spirits worshiped the divinity that lay beyond the idols. However, over time, they came to worship the idols themselves, which was unavoidable once the Idola had taken hold. This turn of events is how the idol-ruled Primate Spirit Garden came to be. Having exchanged beast spirits for idols as their rulers, the human spirits' plight continues, but to whom will they turn next...?
