Until the Mightiest Lycoris Is Reduced to a Sow (Basenokim)

In a Shinjuku Heart hideout, Chihaya-chan dominates a captive male thug, forcing him to drink a substance that induces breast growth and lactation before using a brainwashing device to erase his identity. She overwrites his personality, assigns him the new feminine identity "Zina," and trains him into a compliant, profitable brood sow. After documenting her success, Chihaya-chan commands Zina to begin a mission as she sets her sights on a new target, Chisato Nishikigi.
