Scipio

Scipio is the being that controls the tower. Liana states that some people look up to him as a god, despite him being an AI. This is further proven as Liana often says common phrases (e.g God help me) but with Scipio replacing the word "God" (e.g. Scipio help me).

Physical Appearance
When Scipio is in a physical form, he has dark hair in a ponytail, and cold blue eyes, giving him the same appearance as Leo.
