Babylon

Babylon is the Goddess who resides in the Holy Grail that was in Demon King’s Labyrinth. Babylon appears to be a middle school student wearing her uniform. Her figure is small and can fit in the palm of Horn's hand which is the size of a child. Babylon is a playful sort, very bright and bubbly. She likes to provoke Horn, has an adventurous spirit, and often withholds information that is valuable to Horn, which causes her problems. She acts like a spectator, but Horn makes use of the fact that she is the only one who can see her and hear her, to force her to work in her favor about threatening to damage the Holy Grail.
