Weakest Black Ant? Actually the SSS Broodmother!

A slum girl summons a legendary broodmother after retrieving her destroyed potion from a fire.

Anna Black endures three years in the slums selling her father's blood to afford a single summoning potion. When a wealthy antagonist incinerates the vial, she plunges into the flames to recover the liquid and completes the ritual. The process manifests the SSS Broodmother, a entity absent from all human records. Bystanders immediately ridicule the summon as a worthless E-rank insect, unaware of its true nature.
