Kuroneko no Kenshi

Branded as useless despite his true potential, Nine is secretly one of the strongest adventurers alive. With a magic value of just 1—nearly zero—and stuck at the lowest F-rank, he works as a frontline fighter in a party that exploits him, forcing both him and his beloved cat Enu to handle all the menial labor. Everything changes when the party leader sells Nine’s treasured black sword, a keepsake from his father, and even resorts to violence against Enu. Having reached his breaking point, Nine declares his departure to begin a new life. At that moment, he crosses paths with the S-rank adventurer known as “Dahlia of Flash” and is soon recruited by the continent’s most powerful team, the legendary “Red Hawk,” setting him on a path toward revealing his overwhelming strength.
