Four Monsters? Nah, They're Pets.

The Story

Four SSS-level apex males despise a woman they view as their common enemy. Her F-rank abilities seem trivial until she mends a minor scratch, triggering a dramatic shift in their allegiance. These powerful beings now compete to serve as her slaves, weapons, and pets. The dynamic fractures when an outsider attempts to sell them into the black market. The previously useless girl responds to this threat by dismantling an entire kingdom using her four monstrous companions.
