God, also known as Kami-sama, is an omnipotent deity who holds control over the worlds that Touya and other beings inhabit. He has the power to manipulate events and occurrences in these worlds, and is often seen as an all-knowing figure. In order to interact with humans, God has taken on the persona of Touya's grandfather and goes by the name Shinnosuke Mochizuki. While he is a benevolent entity, he can also be unpredictable and mysterious in his actions, making it difficult to predict his motives or intentions.
