The primordial god created first by the Creator. Her entire body emits a holy white light or a transcendental divine aura, possessing a cold and silent visual that suffocates and overwhelms mortals who face her without her saying a single word. She presides over the 'Cosmos' and the 'Creation' (Genesis) within the world and is the creator of the cat beastmen. Thus, her appearance resembles a cat. Opposite to Alpha, who is in charge of chaos, she is tasked with maintaining the rules and order of the world. Formal and cold-hearted. She is merciless and resolute, to the point of attempting to judge even innocent mortals. Quite heavy and wise, she gives off a more calm and rational vibe compared to the taciturn and arrogant Alpha.

The second god made by the Creator, standing on equal footing with Genesis. The 'God of Chaos' and the creator of the dog beastmen. His appearance resembles a holy yet majestic dog. While Genesis presides over order and cats, Alpha rules over chaos and dogs. When the lower angels and the Seraphim fail to properly handle the turmoil on earth, he finally loses patience and descends to the surface with Genesis. His personality is very serious and wise, with firm determination regarding his goals. However, at the same time, his arrogance and pride regarding his authority are extremely strong, leading him to openly mock and ignore mortals' struggles as "useless acts." He is the final boss who pressures the shelter in the latter half of IF6, clashing head-on with Lucifer's group and leading the world to destruction (Black Hole Ending) with his overwhelming power.
