At a young age, Brahm was abandoned by his family and thus has no memory of them. He was alone for roughly two years until he was eventually taken into the Mothfia by Luminia. This group became like an adoptive family to Brahm, although he had some trouble getting along with others in the group. Being young meant he wasn't exactly considered skilled enough to do many missions. This pushed Brahm to want to learn to throw knives and eventually evolved to him learning to fight with any type of blades.

As a teenager, Brahm was considered old enough to take on missions, much to his adopted mother, Luminia's, dismay. Brahm has since been working for the Mothfia, mostly handling some matters pertaining to the Drugsune Mafia. Brahm has been in countless fights, including one where his eye was badly damaged by Crys (a member of the opposite Mafia). The action led Brahm to take a temporary leave from his jobs in the Mothfia until he was fully healed.
