Marte (マルテ) is a US Navy veteran who failed to become a member of Stars due to being injured and losing his ability during training. His pseudonym is "Mars", based off being a Planetary-Class Magician candidate. 
He and the other possessed individuals met up with Shiba Tatsuya to talk about their situation and what they've been doing. When this occurred, a several-party confrontation erupted, resulting in him getting killed when Angie Sirius shot a bullet in his chest, and afterward his body combusted.
