During one of her training, Essi caught this strange man watching her from afar. Rexus is his name - or that is what he claimed. He is very soft-spoken despite his large build.
Rexus is always there whenever Essi needs someone to confide to. He can be found randomly in Pegasus Park.
In Essi's Words: "What’s with this guy? For someone with this kind of build, he is incredibly mild-mannered."
