Both men and women can audition for this character.

Carl is a young boy who, like Noel and Jin, was a student at the Military Academy, but dropped out without warning while Noel and Jin graduated. He is currently after Ragna's bounty and the Azure Grimoire, leading him to become a vigilante. He travels with a maid-like puppet called Nirvana, whom he believes to be his sister Ada. He is unwilling to see that she is in fact the Nox Nyctores Deus Machina: Nirvana, a causality weapon in the form of a marionette which amplifies its owner's desires to kill. After several people attempted to disassemble or remove Nirvana from him, Carl became extremely paranoid and possessive over her. He is the son of Relius, whom he hates and refuses to call his father. Despite this, over the course of the series Carl begins to slowly become more like Relius-a development many characters note. In the end of Central Fiction, Carl peeks into the boundary and is wounded in his right eye, blinding it but giving him an understanding of the nature of souls. The finale of the series hints that Carl will walk down the same path as his father, donning an eyepatch with the same design as his father's signature mask. His Drive, Automaton, enables him to control Nirvana in battle. 

Carl has a very professional mindset, and dislikes being treated as a kid. He is always calm and collected, even when staring down a foe.

This, however, is a side effect of Nirvana. Behind his mature facade, Carl hides an almost crippling dependency upon his sister Ada. He suffers greatly on the inside because he has practically lost his entire family to his father Relius’ experiments. From the get-go, the incident with Relius caused him to believe that all adults were liars who would only use him for their own ends. With the help of Litchi, Carl learns that his beliefs are not entirely true, and he overcomes his sorrows. Carl now wants to grow up to be someone like Litchi and Bang – good people who help those in need. It is for this reason that Carl did not condemn Litchi for siding with Relius and the NOL, and instead shows concern that she is in danger.
