Killer's Familia

Baal and Levi belong to a warrior race known as the horned people. The boss of an assassination familia took them in and raised them from a young age, expecting them to become loyal protégés. Instead, he now spends every waking moment trying to survive their chaotic idea of "family bonding." They’d gladly kill for him—and with their terrifying destructive power and loose morals, they just might kill him by accident! Baal and Levi love their boss, but the boss just wants them gone! Love collides with deadly bloodlust in this makeshift-family battle comedy made up of literal monsters and heartless killers!
