A boy born to a scoundrel and a lowlife, Levi had very little growing up. His father was a passerby who impregnated Itte and left her with the pups. They weren't more than three months old when Itte died and left them stranded. Were it not for their elder brother Kenny, the children would have been left to starve. Kenny spent a good deal of his time as a traveling mercenary, so he took an opportunity to leave Erwin and Reiss with a trusted friend - a she-wolf called Uri - where they were promised a good life. Levi was taken under his wing and taught how to work. Kenny taught Levi everything he knew and the young wolf flourished.

Already in his first year of life, Levi has managed to get himself in trouble with a gang and make a name for himself as a dangerous opponent. The yearling has recently branched out on his own, opting to work a scouting job for a friend of his brother's. Before waking, Levi was entangled in a fierce battle between an opposing group.
