One of the characters of Tsu Mingmei's "Heaven and Earth Are Useless".

三命の顶神

In ancient times, three goddesses joined hands to create the entire universe. They possessed incredible power and the ability to perform miracles, and with or without their records, all mankind in later generations revered them as a symbol of an invincible god.

The lower world they created was the existence of the Tree Thunder Star and the universe, and they were beyond the three-dimensional, high-dimensional, or even extra-dimensional existences. But they don't know if there is a higher dimension above them, so they seek something that can reach beyond the dimension, and wander between the beginning of hope and the end of hope.
