Charon is a laconic, quiet individual whose few words are blunt and brief. Charon simply seems to be in her own world, and repeatedly proves that she is neither shy nor scared of the Sinners. Charon stays disconnected from the group and shows no interest in becoming close with them. 

She also refers to herself exclusively in third person.

She's 20 years old.

Charon carries around a weapon, that being a black, square-type oar.

Charon likes to run over people and feed them to Mephistopheles.
