Not much is known about Cesar himself, but it can be inferred that he had an ISTP personality. He can be realistic, practical, and rather reserved. He may be difficult to get to know. He can be wary of people given that there are dangerous entities called Alternates. He's typically soft-spoken and can stammer over his words when he gets anxious. His best friend is Mark Heathcliff, who has gone missing. He lives in Mandela County, which is somewhere Alternates tend to swarm. He's eighteen.
