Celestine

As a powerful celestial being and member of Heaven's council, this character acted as a mentor to Belldandy throughout her training. Witnessing immense suffering in the mortal realm, he devised a plan to accelerate Earth's timeline, hoping to bypass its painful evolution. However, his attempt ultimately failed, as he realized speeding up time wouldn't bring true growth. Despite his unsuccessful scheme, he departed peacefully once he understood that Belldandy found happiness and fulfillment in her life on Earth.
