I am introducing two characters from
TSUKI GA MICHIBIKU ISEKAI DOUCHUU anime, they are Tomoe and Mio.
Tomoe is Paternal granddaughter of Time Dragon and Maternal granddaughter of Space Dragon King.
Tomoe was taken by her mother to hide away after the "death" of Dragon God, she heard Time and Space Dragon King betrayed Dragon God thus went into hiding in Demiplane.
Mio is Black Spider of Calamity from Stardou Forest, she is Clan Leader of Spider clan. She is sealed by Di Tian after her developing her Hunger/Gluttony curse.
These two along with Bi Ji will be servants of Zhongli. From time to time, Gu Yuena will also follow him.
Maybe later on Gu Yuena will have a daughter with MC (Bai Lu from Star Rail) and Son with Bi Ji(Dan Heng from Star Rail).
