Hecatia Lapislazuli is a Goddess of Hell. Possessing three bodies, she is one of the rulers of Hell. She seems to be enjoying her current situation, where she can freewheel back and forth between different worlds.

She is a Goddess who rules the Hells of the moon, the Earth, and Otherworlds. All worlds, excluding the moon and the Earth, are Otherworlds, even places such as Senkai and the Dream World. In other words, she is such an exceptionally powerful being that she literally has the entire world in the palm of her hand.

One could say that a woman of her caliber, who is somewhat of an outlaw, left to act with wild abandon is nothing short of a disaster waiting to happen. However, there is not a single soul who can force her to behave appropriately as a ruler of Hell. That in itself shows a glimpse of how alarmingly powerful she is. The only salvation is the fact that she is happy with the way things are. But if she is ever displeased, or grows tired of the status quo, then who knows what will happen...?

The world continues to stay balanced only because she is satisfied with how things are. This, in turn, acts as a deterrent to those who wish to disrupt the status quo. She truly is a guardian of peace, worthy of being called a Goddess. However, one must not forget that this Goddess could very well turn into the worst possible devil imaginable. By her mere whim, the boundaries between worlds could very easily collapse and throw everything into chaos.

Good and evil are two sides of the same coin. Every being can take control of both and willingly choose between the two. Hecatia's choice may have a more substantial effect on the world, but every being's decision has an impact even if they themselves are unaware of it. It is important to understand that the world keeps going round due to the miraculous balance between good and evil, maintained by everyone's decisions―big and small.
